Command reference
Use /recall in Slack. Answers and search results are private to you and include source links.
/recall ask
Ask a question in plain English. RecallHQ retrieves relevant messages and produces an answer grounded in that evidence.
/recall ask <question> [in:#channel]/recall ask Why did we switch to Postgres? in:#eng/recall search
Return ranked message excerpts with links to the original Slack messages.
/recall search <terms> [in:#channel]/recall search pilot success criteria in:#product/recall catchup
Recap updates, decisions, blockers, and next steps over an inclusive date range of up to 32 days. Dates use your Slack timezone, with UTC as fallback. Large ranges or incomplete imports carry a partial-coverage notice.

Summarize an indexed thread. Paste the message link from Slack’s Copy link action; the channel must be indexed and accessible to you.

Find explicit decisions from the last seven days in your accessible, ingested channels.

Inspect accessible channels, message counts, history coverage, embedding backlog, and import errors.
/recall status/recall status/recall syncADMIN / OWNER
Workspace admins and owners can retry a full history import for a channel. Slack’s history limits still apply.
/recall sync #channel/recall sync #eng/recall forgetADMIN / OWNER
Workspace admins and owners can disable ingestion and purge a channel’s indexed content. The bot asks for confirmation before removal. Inviting the bot again explicitly re-enables a disabled channel.
