Private content is excluded by default, mirroring bbPress's own visibility rules. You can opt in selectively, for example to expose a moderators-only forum to a moderators-only bot. Even when opted in, retrieval still respects user role, so public visitors never see private content even if the indexed corpus contains it.

Yes, both topics and their replies, with respect to bbPress visibility. The reply text is what usually contains the working answer, so indexing replies alongside the topic is essential. Pending and spam replies are skipped, and trashed replies are removed from the vector store on save so deleted content stops being citable within minutes.

Yes, the visitor's display name and member role are exposed to the system prompt. The bot can greet a returning member by name and adjust tone for moderators versus regular subscribers. Role-based context also unlocks per-role display conditions, so a moderator-only bot can run alongside a public bot on the same forum.

OpenAI Files vector storage indexes tens of thousands of topics per forum without query latency creeping up, because retrieval runs on embeddings rather than the topic post type table. Indexing is incremental, queued on post save, so years of archive can be ingested once and then maintained on the fly forever after.

Yes. BuddyPress leans on the same bbPress topic and reply types for its forums, so the same setup covers a BuddyPress + bbPress integration with no extra config. Activity streams from BuddyPress are not indexed by default, since they are conversational rather than canonical, but they can be opted in if the activity stream is your knowledge base.

Yes, works with WPML, Polylang and TranslatePress for per-language replies. The visitor's language is detected and the bot replies in it, even when the source topic was written in the site's default language. International plugin support forums end up with a single bot rather than one bot per locale.

Splits and merges trigger a re-index on the affected topics. The bot picks up the new structure within minutes, so a freshly merged topic stops citing the old fragments. This matters for active moderation, where re-organizing the archive should not break the bot's accuracy until the next manual re-index.

Subscriptions are not used as a ranking signal by default, but they can be exposed to the system prompt so the bot says 'you are subscribed to this topic, you'll get an email when there's a new reply.' That turns the bot into an account assistant on top of a forum search, which is useful for support forums where notification settings are a recurring question.
