AI grounded in your community's own knowledge.
ForumBot is a managed AI assistant for XenForo. Your registered members get answers drawn first from your own content, and you decide who can use it, how it's grounded, and whether its public replies are reviewed before they post. There is no OpenAI or Anthropic account to bring, no API keys, and no server access, and a license key is the only credential your forum needs.
Note: ForumBot is developed with AI assistance using XenForo's publicly released 2.3.10+ developer tooling and following its documented resource standards (see the HYS here). Releases are built and tested locally and run on TONMO before they ship.
Running on a 25-year archive
TONMO.com has run this stack in production since 2025 (as "Octobot"), answering from a 25-year archive of community knowledge. Member feedback:"...For someone trying to learn this makes it so much easier to find what I'm looking for. So far the responses have been excellent, or leading me to previous threads to read more."

What your members get
- A private chat page: a 1:1 AI conversation on its own forum page (guests are prompted to register or log in).
- "Ask about this post": a robot icon on posts opens a chat pre-loaded with that post and its thread context for an explanation, summary, or follow-up.
- @tag in threads: permitted members (based on usergroup) can tag the bot by name in any post, and it replies in the thread in a visually distinct reply. Its replies are held for moderator approval before they appear, unless you grant the usergroup a bypass.
- Project Info: members save personal context (setup, goals, background) and opt in to include it per chat for more tailored answers.
- Daily message counter: members see how many messages remain today and when the count resets, and unlimited groups see a running tally.
- Share a chat: members can create a public, read-only snapshot of a conversation (off by default). Shared snapshots are stored in your forum's own database and auto-delete after 5 days.
What you control
- The agent prompt: engineered for your forum's domain, tone, and rules, combined with our standard XenForo-optimized instructions.
- Per-usergroup permissions: you decide which groups can use the chat and which can tag the bot (guest access is not supported).
- The moderation queue: bot replies to member @tags go into XenForo's standard Approval Queue for staff review, and trusted groups can be granted an instant-post bypass.
- Knowledge base ingestion: you can optionally ground answers in your own articles, threads, and forum structure (see below).
- Chat logs: an admin chat-log viewer with member feedback ratings, plus a viewer for active shared chats.
- Bot identity and starter prompts: set the bot's name and notice text, offer clickable starter prompts, and ship with auto-installed privacy and help pages.
- An optional upgrade nudge: show daily-limited members an "Upgrade for unlimited access" link beside their counter (off by default).
How it works
The AI backend is powered through Xpertloop. A bot answers from its agent prompt and general knowledge, and you can ground it in your own content with three optional CSV exports that we upload and configure during onboarding:- {site}-articles-kb.csv: articles, blog posts, docs, or other non-forum content the bot can cite.
- {site}-forums-kb.csv: thread titles and post content, so the bot can draw on community discussion.
- {site}-nav-kb.csv: your forum's sections, so the bot can point members to the right place.
