Best Free AI Customer Service Tools

Help Scout's free plan is a human inbox, not a bot: up to five users, one inbox, one Docs site and 100 contacts a month. Autonomous AI is a separate add-on billed per resolution, with a three-month free trial included. Choose it over Zoho when five people share replies and you want a customer-friendly tool, and accept that contacts, not agents, are what runs out.

• +The shared inbox is mature and feature-rich, including assignment, tagging, SLAs, snooze, saved replies, and workflow automation that requires no developer involvement.
• +AI features are genuinely integrated rather than bolted on, with AI Answers acting as an autonomous agent inside Beacon and inbox AI handling drafting, editing, and translating.
• −Help Scout is not designed for enterprise teams or solo operators, leaving those outside the small-to-mid-sized sweet spot underserved.

The free plan starts without a credit card and centers on live chat that the Lyro AI agent can answer, trained from FAQ uploads, a website scraper or imported Zendesk articles. Anything outside that training is passed to a human. The catch is how paid plans count: billable conversations and Lyro conversations are separate meters. Pick it over tawk.to when an AI agent is the point of the chat widget.

• +Lyro AI agent performs better than expected, handling repetitive queries like order status, return policies, and FAQs without human intervention.
• +Available across web, iOS, Android, Windows, Mac, and Chrome, giving small teams the flexibility to run support on the go.
• −Pricing structure is likely to frustrate buyers who don't fit the specific use case Tidio is optimized for.

Two seats, a website chat widget, mobile apps and a contact form for 100 customer profiles make up the free plan, with no AI credits at all. Hugo, its AI, runs on usage credits that begin on Mini, and a pay-as-you-go switch keeps it running when they are spent. Choose Crisp over tawk.to when a pair of people want phone apps and a tidy widget, and AI can wait.

• +Flat-fee workspace pricing eliminates per-seat chaos, making costs predictable for growing SMB teams.
• +Shared inbox consolidates WhatsApp, Facebook Messenger, email, and website chat into a single unified view.
• −The chatbot builder and Hugo AI workflow tool are two separate systems, which frequently confuses new users.

This one is free for good: unlimited agents and chats, with an inbox, CRM, pipeline, knowledge base and automations included, so a growing team never pays per seat. Chat, email, WhatsApp and SMS land in one place. The catch is that AI and some other features sit behind paid add-ons, and there is no trial because the free plan is the product. Pick it over Zoho when seats matter more than ticket depth.

• +The core platform is genuinely free with unlimited agents and full chat history included at no cost.
• +tawk.to holds over 20% market share in its category, suggesting strong reliability and widespread adoption since 2013.
• −Removing tawk.to branding from the chat widget requires an additional paid add-on, which undermines the fully-free positioning for many businesses.

Botpress gives 100 conversations with no top-ups or overages, so there is no surprise bill when they are gone. Studio, Desk and the Agent Development Kit are all on the free plan, with no time limit on access. That makes it the builder to pick over Chatbase if you want flows you shape yourself. The catch is that 100 conversations disappear quickly once a site has regular visitors.

• +Botpress Studio and Botpress Desk are both included on every plan, including the free tier, which is genuinely unusual in this category.
• +The Agent Development Kit (ADK) is available on all plans including free, whereas most platforms gate API access behind paid tiers.
• −Custom domain support for knowledge bases is only available on Plus plans and above, limiting free tier users in meaningful ways.

One bot, 50 source pages, 100 AI credits a month and one user, with no card needed. DocsBot can learn from 37 or more content sources, and Freshdesk or Zendesk can feed it, which suits a support team with a written knowledge base. The catch is reach: there is no WhatsApp and no native email channel, and unbranded widgets are listed from Business. Pick it over Chatling for document-heavy help.

• +Supports 37+ content source types including PDFs, Google Drive, Notion, Confluence, YouTube transcriptions, and Zendesk articles, covering an unusually wide range of inputs.
• +No coding required to build a functional AI chatbot from existing documentation.
• −No native live chat interface or agent inbox, meaning DocsBot only handles the bot layer and teams must manage post-escalation conversations elsewhere.

The free Support Agent runs on 20 credits, one AI agent and 50 stored webpages, good for roughly 10 resolutions a month, and a Conversion Agent for lead qualification has its own free plan. The product also reaches WhatsApp, SMS, voice and Microsoft Teams, with a mobile SDK. Choose it over DocsBot when channels matter, but ten resolutions is a trial, not a month of support.

• +Trains on a wide variety of content sources including websites, PDFs, Google Drive, SharePoint, and past support tickets.
• +Every chatbot reply cites its sources, giving users transparency and building trust in AI-generated answers.
• −The dual Support Agent and Conversion Agent framing is ambitious, but it's unclear whether the execution consistently delivers on both use cases.

Live chat, a bot trained on a knowledge base of up to 500,000 characters and one seat come with the free plan, no card needed. Customization is limited, and paid plans add credits, agents and seats. It reaches your website and the major social messaging apps. Pick it over Wonderchat when you want room for a big help library, and treat the free credits as a trial pot rather than a month of support.

• +Genuinely functional free plan includes 200 AI credits per month, one AI agent, and live chat with no credit card required.
• +No-code AI chatbot builder allows small teams to deploy bots without writing a single line of code.
• −No ticket management or SLA controls, making it unsuitable for teams migrating from Zendesk or Freshdesk.

Built for online shops, the free plan allows up to 1,000 monthly visitors and 100 products, with generative AI, order status, abandoned cart messages, five FAQ prompts and six months of data storage. It runs as website chat, with handover to a human available. Pick it over Chatling for a Shopify store, and skip it for long documents, since document prompts are listed from the paid Starter plan.

• +Built specifically for ecommerce with native integrations for Shopify, WooCommerce, and BigCommerce via a single JavaScript snippet.
• +Generative AI is included even on the free plan, which is rare among competitors at this price point.
• −Ticket management is form-based with email alerts only, it is not a proper helpdesk solution.

Dante-ai builds a GPT-4 chatbot from your own content with no code, then places it on your site or WhatsApp, with Slack reachable through Zapier. Its plans count credits, extracted-text characters and team seats. Branding removal, human handover and knowledge gap insights are listed on Pro, so a small team should expect a paid plan before the bot looks like its own. Pick it over Ochatbot for general website help, not shop catalogs.

• +No-code setup allows businesses to build GPT-4-powered chatbots without any engineering resources or programming knowledge.
• +Supports training on multiple content types including PDFs, URLs, and plain text, making data ingestion flexible.
• −Analytics and reporting are weak, with minimal documentation and no notable user enthusiasm around dashboards or conversation insights.

The Start plan has no platform fee, asks for no card and comes with two credits and an inbound number. Per-minute billing begins straight away, which keeps a first test cheap but makes the free part small. The caps are stated plainly: 10 concurrent calls and 100 calls a day. Choose Bland over Vapi when phone call automation is the whole job and you want those limits and commercial rights spelled out.

• +All-inclusive per-minute pricing covers the language model, transcription, and voice synthesis together, no hidden API stacking from third parties.
• +Runs entirely on proprietary infrastructure with no OpenAI or ElevenLabs pass-throughs, reducing unexpected costs at invoice time.
• −Voice cloning is locked to Enterprise tier and requires a custom voice actor arrangement, limiting access for smaller teams.
