Setting Up Auto-Sync So Your Chatbot Never Goes Stale

LLumen Chat Team2 min read

A chatbot is only as good as the last time it read your docs. If someone updates pricing in Notion and the chatbot doesn't know for two weeks, it'll confidently give a wrong answer — which is worse than not answering at all.

Turning it on

Each connected source (Notion, Google Drive, or a website crawl) has an auto-sync toggle and a sync interval. Turn it on and the source is re-checked automatically on that schedule — no manual re-sync required for routine updates.

Choosing an interval

There's no single right answer; it depends on how often the underlying content actually changes:

  • Fast-moving docs (a changelog, active FAQ) — sync more frequently so edits show up in chatbot answers quickly.
  • Stable reference material (a terms page, an onboarding guide that rarely changes) — a longer interval avoids unnecessary sync runs without meaningfully delaying updates.

Manual sync still works

Auto-sync doesn't replace the manual Sync now action — if you just published something and don't want to wait for the next scheduled run, trigger a sync directly from the source's page.

What happens on a sync

Only what changed gets reprocessed — a sync doesn't re-chunk and re-embed your entire source from scratch every time, so frequent syncing isn't wasteful. If a sync fails (a revoked permission, a deleted file), the source shows the error so you can fix it rather than silently falling behind.

Set it once per source and stop thinking about it — configure auto-sync on your existing sources so the next doc update reaches your chatbot on its own.
