Marvin tested AI chatbots including ChatGPT, Claude, and Intercom across real business workflows, evaluating accuracy, agentic capabilities, and integrations with existing tools.


“My order is wrong” became my quickest test for an AI chatbot. I watched to see whether it asked a useful follow-up question or pasted a help article that missed the problem.
A good answer was only the start. I checked whether the bot could find the right company information and take the next step. If it had enough detail to help but still left a messy ticket for a person to sort out, I counted that as a miss.
Over several weeks, I tested more than 20 chatbots across support, lead qualification, document analysis, and connected workflows. I looked at their answers, knowledge retrieval, integrations, and ability to act after answering.
I wanted to know what happened when a request was unclear, the answer was buried in a document, or a customer needed someone to take over. I used five checks to compare how each tool handled those moments:
I kept checking what the rep received. If the bot had already asked about budget and timing, those answers should be there when a person steps in. Having to ask the visitor again made the handoff feel unfinished.
AI chatbots for businesses handle conversations with customers or employees. They can answer questions using company information, ask for missing details, and help with the next step. Some book meetings, create tickets, or update connected records.
Some chatbots answer customers on a website or in a support inbox, while others help employees find information and finish work across their apps. If calls are part of your workflow, the Bland AI alternatives comparison covers tools built for phone conversations.
ChatGPT, Gemini, Claude, and Perplexity sit in your team's browser and handle drafts, analysis, and research. They have no built-in help desk, so they rarely face customers directly.
Platforms like Intercom, Zendesk, and Tidio plug into your website and inbox. They answer customers from your help center and hand tough cases to a person. Dialpad covers phone support, and Manychat handles social DMs. Most teams end up with one of each.
Lindy is an AI teammate that lives in your Slack, connects to your tools, and knows your company. It answers team questions with sources, handles support replies, and finishes tasks like CRM updates and meeting follow-ups.
Who is it for? Teams that want one teammate for company knowledge, support replies, meeting follow-ups, and CRM updates, with no code and no IT ticket.

Pricing: Lindy has a free plan with $50 in credits that last 7 days, with no credit card required. Team costs $29.99/user/month for 3,000 credits, pooled across your team. Enterprise pricing is custom.
It takes very little setup to get a useful answer. I asked a plain question in Slack, such as what customers had pushed back on during recent sales calls, and Lindy returned the main themes with a source attached to each one.
I also liked how context carries across conversations and teammates. When a request needed a person to step in, the handoff included enough history to continue without retracing the entire exchange.
Lindy runs on credits, and bigger jobs like dashboards or heavy scheduled workflows use more of them. Monthly credits don't roll over, though top-up credits stay until you use them, so heavy months may call for more monthly credits or a top-up.

ChatGPT is OpenAI's conversational AI platform for writing, coding, data analysis, and workflow automation. You type a request in plain language, and it drafts, explains, or analyzes the answer in a chat, and it can pull from connected company files such as Google Drive and SharePoint.
Who is it for? Businesses that want one versatile tool across marketing, sales, engineering, and support.

Pricing: Free plan available. Business starts at $20/user/month on annual billing ($25 monthly), with a two-seat minimum. Enterprise pricing is custom.
One workspace covered several kinds of work. I could draft a campaign, clean a spreadsheet, and ask for an unfamiliar repository to be explained without moving between specialist tools.
Answers drawn from connected company sources included citations. When I needed to verify a detail, I could open the original file without searching through old Slack threads or wikis.
ChatGPT lacks a built-in customer chat widget and help desk. Teams serving customers will need another platform for routing, ticket management, and agent handoffs.
I’d also review any answer before it reaches a client, especially when it combines information from several company sources.
Claude is Anthropic's AI assistant for deep reasoning, document analysis, and complex problem-solving across business workflows. You chat with it in plain language, and you can upload files like PDFs, spreadsheets, and documents for it to read, summarize, and work from.
Who is it for? Teams that work with large documents, codebases, and nuanced writing, especially engineering, product, HR, and marketing.

Pricing: Claude plans start at $20/month for Pro, billed monthly. Max starts at $100/month. Team costs $25/seat/month for Standard or $125/seat/month for Premium. Self-serve Enterprise starts at $20/seat/month billed annually, plus usage fees. A free plan is available.
Projects changed how I'd run a long piece of work. Open a chat inside one and the context is already loaded, so there is no re-uploading the brief or repeating instructions.
Seeing a summary of Claude's thinking is the other win. It lets you catch a bad assumption early, before it costs an hour of backtracking.
Customer support features are the main limitation. Claude lacks a customer-facing chat widget, ticket queue, routing rules, and live-agent handoffs. Adding those tools would let support teams manage conversations without paying for a separate platform such as Zendesk or Intercom.
Gemini is Google's AI assistant, built into Gmail, Drive, Docs, and Chrome to help with research, document analysis, and communication tasks. It answers questions, summarizes documents, and drafts messages using the emails, files, and web pages open in those apps.
Who is it for? Teams already on Google Workspace who want AI help without switching between apps.

Pricing: Gemini plans start at $4.99/month for Google AI Plus, with Pro at $19.99/month and Ultra from $99.99/month. A free plan is available.
Gemini feels most useful inside Gmail and Drive, where I could ask it to find a restaurant a client recommended or summarize a spreadsheet without opening the file and copying its contents into another tab.
I also found Gemini Live helpful during early planning, especially when I wanted to talk through a strategy before I had enough structure for a document or presentation.
Workspace settings can create an uneven experience across a team because admins control which Gemini features and connected apps each employee can access. This can make rollout and troubleshooting harder.
Teams that rely on Microsoft 365, Slack, or other ecosystems may also need more setup to bring their company context into Gemini.
Perplexity is an answer engine that delivers real-time, cited research across the web and internal company data. It answers a question in plain language and attaches a source link to each claim, so every answer can be checked against where it came from.
Who is it for? Sales teams, investors, R&D departments, and anyone who needs fast research backed by verifiable sources.

Pricing: Perplexity plans start at $20/month for Pro, with Max at $200/month. A free plan is available.
Perplexity makes verification part of the answer by placing sources beside its claims. When I asked about a competitor’s pricing model, I could open each citation and check the details within seconds.
For customer research, Social mode helped surface recurring complaints from Reddit threads and community discussions that were easy to miss in polished company pages.
Perplexity lacks built-in help desk and CRM workflows, which limits what happens after the research is complete. A finding still needs to be copied into another system before a team can act on it.
Source quality also varies across the web. I’d open the citations behind any claim that could affect pricing, strategy, or a customer decision.
Intercom is a customer service platform with an AI agent called Fin, a shared inbox, and a Messenger widget for web and mobile. Fin answers common customer questions from the company's Help Center, and human agents take over the harder conversations in the same inbox.
Who is it for? Companies that want live chat, AI support, and automation in one place, especially those with a high volume of customer queries. Our best customer service chatbots comparison covers 11 tools built for round-the-clock support.

Pricing: Intercom plans start at $29/seat/month for Essential, with Advanced at $99/seat/month and Expert at $139/seat/month. Fin AI Agent costs $0.99 per resolved outcome. A free trial is available.
Fin answered common support questions within seconds and pulled its replies from the existing help content. I didn’t have to rewrite the knowledge base or build a long FAQ before it could handle useful conversations.
During testing, most tier-one questions stayed with Fin and reached a resolution without a human handoff. Messenger also took only a few clicks to match the site’s branding and control what visitors could see.
Per-resolution pricing makes the bill harder to predict because the $0.99 outcome fee sits on top of Intercom’s seat costs. A successful month with more automated resolutions can also become a more expensive month.
The interface packs in a lot of settings for inboxes, workflows, Messenger, and Fin, which made the first setup feel dense even with the guided instructions.
The naming now takes extra explanation. Intercom renamed its company Fin in May 2026, while Intercom remains the help desk product. Salesforce completed its acquisition of Fin in September 2026, and Fin AI Agent continues to work with other help desks such as Zendesk.
Zendesk is a customer service platform that combines AI agents, a ticketing workspace, and messaging across email, chat, social, and phone. The AI agents answer common questions and hand harder ones to human agents, who work from the same Agent Workspace.
Who is it for? Growing businesses that want a full suite of support tools, especially teams that pair live agents with AI automation to handle high inquiry volumes.

Pricing: Zendesk plans start at $25/agent/month for Support Team, or $19 billed annually. Suite Team costs $69/agent/month ($55 billed annually), and Suite Professional costs $149/agent/month ($115 billed annually). Suite Enterprise + Copilot uses custom pricing.
Zendesk's bots read the context well enough to land a helpful reply partway through a multi-step flow.
Automation flows plug into the messaging system, so common questions get answered before they reach a human. When one does, the Agent Workspace keeps the whole thread in one place.
AI agent costs rise with automated resolution volume, which makes the base seat price an incomplete estimate. Support Team includes five automated resolutions per agent each month, while additional committed resolutions cost $1.50 each. I’d estimate expected volume before choosing a plan.
Tidio is a customer service tool for chatting with website visitors, answering questions, and running email campaigns from one dashboard. Lyro, the AI responder, answers product and support questions, and live chat lets a person step in when a shopper needs help.
Who is it for? Small and mid-sized ecommerce businesses that want to boost sales, handle support, and stay connected with customers in real time.

Pricing: Tidio plans start at $29/month for Starter, with Growth from $59/month and Plus from $300/month plus usage fees. Premium pricing is custom, and a 7-day free trial is available.
What surprised me most was how naturally Lyro adjusted its replies after reading the conversation context. Its answers felt specific to the customer’s question and avoided the stiff wording I expect from a scripted chatbot. Having everything in one panel also cuts down tab switching during a support session.
Tidio meters human-handled conversations and Lyro conversations separately, which makes the monthly cost harder to estimate for a busy store. I’d model both types of usage before choosing a plan.
Free, Starter, and Growth also cap teams at 10 seats. Larger teams need Plus, which starts at $300 per month and adds usage fees.
Dialpad is an AI-powered platform that brings voice calls, video meetings, and messaging into one app. Call AI transcribes conversations, takes live notes, and writes summaries, while Dialpad Support gives agents coaching tips during customer chats and calls.
Who is it for? Businesses that need a strong communication system, especially remote or hybrid teams that rely on voice and video to stay in sync.

Pricing: Dialpad Support, its contact center product, starts at $95/user/month, or $80 billed annually. Dialpad Connect, its calling and meetings plan, starts at $27/user/month for Standard and $35 for Pro. Enterprise pricing is custom, and Connect comes with a 14-day free trial.
Using Dialpad for meetings and customer support in the same week showed me its range. Live notes, transcripts, and summaries appeared during each conversation without any manual note-taking, which felt like having an assistant follow every call.
During one call, I moved from desktop to mobile without reconnecting, and the conversation continued while the notes stayed current.
Initial setup requires more planning than a basic chatbot. Phone numbers, routing rules, permissions, and contact center workflows all need to be configured before a team can use the full system.
Teams looking mainly for website chat may also pay for calling, meetings, and routing features they won’t use. Dialpad’s contact center products cost more than its base communication plans.
Manychat automates replies to comments and direct messages on Instagram, TikTok, Facebook Messenger, WhatsApp, and Telegram. A comment or keyword triggers a DM flow that sends the promised link, collects an email, and tags the contact for follow-up.
Who is it for? Creators, social-first brands, and ecommerce stores that win customers in DMs and want to capture leads without staffing an inbox all day.

Pricing: Manychat plans start at $17/month for Essential, with Pro at $39/month, Business at $99/month, and Advanced at $199/month. A free plan is available, while Essential and Pro include 14-day free trials.
The comment-to-DM flow was the feature I kept coming back to. When someone commented on a post, Manychat sent the promised link by DM within moments and continued the conversation from there.
For brands with an active Instagram audience, that shortens the path from engagement to lead capture. Nobody has to monitor comments or copy email addresses into another tool.
Manychat offers limited support management compared with a dedicated help desk. There’s no full ticketing system or help center for tracking complex customer issues.
Pricing rises with active contacts, which can make audience growth more expensive. I’d estimate the monthly contact count before choosing a plan, especially for accounts running frequent campaigns.
If you want a bot trained on your own documents, two builders belong on the shortlist next to the picks above.
Chatbase fits teams that want a bot trained on their help docs and live quickly, while Copilot Studio fits teams already on Microsoft 365 that want custom agents billed by usage. Both bill by credits, so estimate your monthly conversation volume before choosing.
The best chatbot depends on where the conversation begins and what needs to happen next. A support question, sales inquiry, and internal research request each call for a different tool.
Intercom fits teams handling a large volume of repeat questions. Fin AI Agent answers from approved support content, costs $0.99 per resolution, and passes unresolved conversations to an agent with the context attached.
Zendesk combines AI with a full support operation, including tickets, messaging, routing, and agent tools. Every plan includes a monthly allowance of automated resolutions, and resolutions beyond it are billed.
Tidio gives ecommerce stores a lighter setup for common product and order questions, and it has a free plan for testing. Dialpad focuses on customer conversations over the phone.
Manychat turns activity on Instagram and WhatsApp into sales conversations. A comment, keyword, or message triggers a DM flow that collects contact details and guides the person toward an offer. WhatsApp access starts on the Pro plan.
Lindy takes over once a lead needs follow-up. It drafts replies, schedules calls, and updates CRM records, and your team can ask it in Slack what a prospect said on past calls.
Dialpad Sell supports sales calls with live coaching, transcripts, and automatic record updates.
The AI lead generation chatbots guide focuses on capturing interest, while our AI sales chatbots roundup covers qualification and conversion.
ChatGPT works well for drafting, analysis, and questions that draw from connected sources such as Google Drive, SharePoint, and GitHub. Claude keeps project files and instructions together, which helps with work that continues across several conversations.
Gemini fits teams working in Google Workspace, where it pulls context from Gmail, Drive, and Calendar. Perplexity is stronger for sourced research, giving each claim a link you can open and verify.
Lindy lives in Slack and answers questions from your meetings and connected tools, with citations. It also handles work that crosses several apps, such as updating a project board after a meeting or sending reminders before a deadline.
Our AI agents for small businesses guide ranks tools by ease of setup and real-world value.
Free plans let you pilot a chatbot before committing budget. Each one caps something, whether messages, contacts, or AI conversations, so use them to test fit with real questions.
For a no-cost start, pick by goal. Tidio suits customer support, Manychat suits social leads, and ChatGPT or Claude suit internal work. Move to a paid plan when you need your own knowledge base, integrations, or team controls.
Ask a traditional chatbot "What's your refund policy?" and it replies with the policy. It follows set conversation flows and answers from the content you gave it.
An AI agent can take the next step too. It can look up the customer's record, log the ticket, update your CRM, or schedule a follow-up in another app.
In a sales flow, one agent qualifies the lead, another books the demo, and a third drafts the follow-up with the meeting notes. Anything with outside impact, like sending an email, can wait for a person to approve it.
Agents take more setup than a basic chatbot, and heavier workloads can raise usage costs. Many teams do fine with a single chatbot for support answers. Consider an agent when answers need to trigger work in other apps.
Setup takes an afternoon on most platforms. This is the order I'd follow:
If you would rather build from scratch, this walkthrough shows how to build an AI chatbot without coding in eight steps.
Match the tool to your workflow before you compare features. Six checks narrow the field:
Tidio is the easiest start for an ecommerce store, with a free plan and Starter at $24.17/month on annual billing. ChatGPT and Claude cover writing and research at $20 per seat. Lindy suits teams that want scheduling and follow-ups handled for them.
Yes. ChatGPT, Claude, Gemini, Perplexity, Tidio, Manychat, and Lindy all have free plans. Tidio's free plan covers 50 conversations a month and Manychat's covers 25 active contacts, so expect to upgrade once real traffic arrives.
Start with one job, such as answering refund and shipping questions. Upload your help docs, FAQ, and a few past support tickets, then write rules for tone and when to hand off to a person. Test with 20 to 30 real questions, launch on one channel, and review conversations weekly.
They can be, but protections differ by vendor. ChatGPT Business and Enterprise don't train on your data by default. Intercom, Zendesk, and Dialpad each report SOC 2 Type II compliance.
HIPAA comes on Intercom's Expert plan, as a Zendesk add-on from Suite Professional, and on Dialpad with a signed agreement. Lindy is SOC 2 and GDPR compliant, with HIPAA on Enterprise. Confirm on each trust page before buying.
Costs range from free to custom enterprise quotes. ChatGPT Business and Claude Team start at $20 per user on annual billing, Lindy Team at $29.99 per user per month, and Intercom at $29 per seat on annual billing plus $0.99 per resolution. Zendesk starts at $25 per agent per month, or $19 billed annually.
