AI Chat (full-page)¶
Use AI Chat when you want a dedicated, full-width conversation with HERC: history, typing comfort, and the same features as the floating chat — without leaving the module.
When to choose this¶
| Need | Use |
|---|---|
| Focused, long session | AI Chat (/chat → open a conversation) |
| Quick question while working elsewhere | Floating chat (bottom-right) — stays on the page you’re on |
| Transcription, keys, or experiments | AI section routes — not the chat lander |
Permissions¶
- Run chat: your role must include HERC / agent run (same as using the assistant elsewhere).
- Thumbs and optional feedback text: same gate as sending messages; aggregated feedback for analytics is admin / AI editor (see AI platform for organization settings).
What you see¶
- Lander (
/chat): KPIs, trend, and a table of conversations (active / archived) — open a row to continue. - Thread (
/chat/conversations/…): full composer, message actions (e.g. helpful / not helpful, edit-and-rerun where available), and command surface (type/for saved prompts,#for catalog/glossary/contracts/flows,@reserved for future agent shortcuts).
Mentions in the composer use structured tokens; matching items are read-only (navigate via links, no mutations from the picker).
Limitations¶
- Replies require a configured model / provider (see AI platform). If nothing is available, the UI explains the gap — not a silent failure.
- Edit-and-rerun replaces the tail of the thread from that user message; it does not keep parallel “versions” of a branch in the UI.
- Stop cancels the in-flight request from the app; provider-side buffering may still finish outside Datahub in edge cases.
Audit & compliance¶
- Feedback and chat usage follow your tenant and roles; do not put secrets in prompts. Provider keys and licensing are covered in AI platform.
Troubleshooting¶
| Symptom | What to check |
|---|---|
| 403 / can’t see AI Chat | Role must allow agent / conversation access. |
| Empty or “no provider” | Admin: provider keys and model config (AI platform). |
| Mention search slow | Large org / many entities; try a narrower #type: or shorter query. |
