Reference Channels
/settings → Reference → Manage button → Reference channels field → pick channels or a category → submit
Picking a whole category expands to every text channel inside it. For each selected channel, Aiko:
- Reads up to 500 recent messages
- Keeps up to 40,000 characters, favoring the newest content
- Skips Aiko’s own messages and empty messages
- Combines multiple channels under channel headings
Submitting this field always replaces the whole channel list with whatever’s selected at submit time — it’s not additive. Clearing every channel and submitting removes the channel-based reference entirely (uploads and links are untouched).
Add or Remove a Single Message
Right-click any message → Apps → Add to Reference / Remove from Reference Lets you include or exclude one specific message without touching the channel list as a whole — useful for pulling in a message from a channel you haven’t fully added, or excluding one noisy message from a channel you have.Both context commands require Discord’s Manage Server permission (or this server’s admin role) — same as everything else on this page.
Upload Documents
/settings → Reference → Manage button → Reference documents field → attach file(s) → submit
Plain-text formats only (.txt, .md, .csv, .json, and similar).
Document Links
/settings → Reference → Manage button → Document links field → one URL per line → submit
Aiko fetches each URL’s readable content (stripped of navigation/boilerplate) and folds it into the reference material the same way a channel or upload is.
- Each link’s content is capped at 40,000 characters.
- Fetching a single link times out after 20 seconds.
- All links are validated (fetched successfully) before anything is saved — if any one URL fails, none of the links from that submission are saved.
Unlike uploads, this field is a full replacement list, not additive — it’s pre-filled with your current links, so if you clear it and submit, all links are removed.Editing in place (add/remove a line, keep the rest) works the way you’d expect.
Limits
Reference channels have no plan-based count limit — only the per-channel 500-message / 40,000-character caps above.Going over your upload or link limit doesn’t delete anything — it just stops including the oldest ones in what Aiko actually reads from, in favor of the most recent ones, until you’re back under the limit.
