Yes. The visitor-side chat is free on every site, with no credit card, no trial wall, and no per-message fees. You bring your own AI key (Anthropic Claude, OpenAI GPT, Google Gemini, or DeepSeek for the public chat), so token cost stays at the provider's API rate — PressBot does not mark it up.
The paid plan is PressBot Pro, which adds the admin agent, 99 tools, Plugin Guardian, Shield, Telegram bridge, GA4, lead capture, and the full 99-tool MCP server. Pricing starts at $99/year for a single site, with Business (5 sites) and Agency (50 sites) tiers above that — the full breakdown lives on the Pro page. External Knowledge (RAG) is included on the free tier — you only need Pro for the admin features above.
