Use automatic smart tags

Automatic tagging

1. 1

   Save a new note, link, image or document while Automatically tag new captures is enabled in Settings. Canvas Perch queues tagging for that item only.

2. 2

   Open the saved item and find Tags. Canvas Perch adds successful generated tags while preserving existing tags.

3. 3

   Use Add tag or a tag’s Remove control to change the result immediately.

4. 4

   Choose Tag again to generate and apply a fresh set for this item.

What is sent

• The request is limited to the item title, up to 8,000 characters of saved text, as many as 100 current tags, and a sanitized 512-pixel thumbnail for a stored image.
• Canvas Perch does not send the whole library, follow a saved remote URL, or run routine OCR for smart tagging.
• Smart tagging sends this limited content to Mistral Large 4 through OpenRouter. A transient failure may send one immediate fallback request to Microsoft Azure-hosted GPT-6 Luna. If both requests fail temporarily, up to four recovery rounds at least six hours apart may use GPT-6 Luna, then Google Vertex-hosted Claude Haiku 5.5 after a transient Luna failure. All routes require Zero Data Retention and deny provider data collection. Canvas Perch still stores your saved items and tags. Read Privacy and processing for retention details.

Control and recovery

• If automatic tags are disabled, open Settings → Notifications and enable Automatically tag new captures. Enabling it does not backfill older items.
• If smart tagging is unavailable, your item is still saved. You can add tags yourself.
• If a newly queued capture or Tag again job fails because providers are temporarily unavailable, up to four automatic recovery rounds may be scheduled at least six hours apart. You can choose Retry automatic tagging now; that supersedes pending recovery. Turning tagging off cancels recovery. Older items are not backfilled; use Tag this item or Tag again to request a new job. Legacy stored suggestions remain unapplied.
