Drift is especially strong for B2B sites where live reps aren’t always available, offering instant engagement with warm prospects.

Top Free AI Chat Assistants for Websites

Chatbase

Chatbase lets you upload your own content — like website pages, PDFs, or help docs — to train a ChatGPT-powered bot that answers visitor questions with context. The setup is code-free, and you can embed the assistant on your site via a simple widget. It’s ideal for personal sites, blogs, or early-stage startups testing AI chat without a budget. The free tier includes a limited message quota but still provides meaningful value for small-scale use or prototyping AI support workflows.

Tidio (Free)

Tidio’s free plan includes a basic live chat widget and chatbot templates for automating common replies. While AI features like Lyro require a paid upgrade, the core system lets users respond manually or use rule-based bots to engage customers. It's a reliable entry point for solopreneurs and small websites looking to offer real-time support without investing upfront. Integration with platforms like Shopify and email marketing tools helps unify customer engagement into a single dashboard.

Crisp Chat

Crisp offers free live chat with a modern UI, multi-device support, and basic automation tools. It’s great for startups and small teams looking to centralize messages from email, Messenger, and website chat in one inbox. While its AI assistant is part of the paid plan, the free version still provides powerful features like canned replies, file sharing, and a shared team inbox. For those needing a polished support solution with room to scale later, Crisp is a smart pick.

Botsonic

Botsonic is a no-code AI chatbot builder that lets users upload documents or link to web pages to create GPT-powered bots. You can then embed the assistant as a floating widget or iframe on your site. The free plan includes limited usage and branding but is enough for small websites or MVPs testing conversational AI. Botsonic also supports API integration and custom styling, making it suitable for creators, educators, or businesses looking to offer helpful support without coding.
