Capture a note, link, image, or document

Save an idea quickly to the inbox, add context and tags, and choose a collection when you are ready to give it a home.

Follow the steps

Open Inbox or Library and choose Capture an idea.
Choose Note, Link, or Image or document. A note needs a title; a link also needs a safe external URL; an upload uses a local file.
Add optional notes, comma-separated tags, and a collection, then choose Save idea. New captures go to the inbox until you move them out.
Open the item later to edit its context, add it to a canvas, extract a palette from an uploaded image, or start document extraction.
When automatic smart tags are enabled, a new capture can queue tagging automatically. Successful tags are added to the saved item and can be edited or removed immediately.

The server upload allowlist currently includes JPEG, PNG, WebP, GIF, PDF, plain text, Markdown, DOCX, PPTX, and XLSX MIME types.
Uploaded files are stored as file or image assets. Binary uploads use the session-authenticated upload flow; the personal REST capture endpoint accepts an externally hosted image URL instead.
A link must use a safe external URL. The API rejects unsupported or unsafe URLs rather than treating them as ordinary text.
Smart tagging sends only the item title, up to 8,000 characters of saved text, current tags and, for a stored image, a sanitized 512-pixel thumbnail. It does not scan the rest of the library, fetch a remote source URL or run routine OCR.

If a file is rejected, check both its MIME type and size. The API accepts files from 1 byte through 20 MB.
If a link will not save, include an https or other accepted external URL and remove local-file or unsupported URL schemes.
If the item is not in Library, open Inbox or clear the collection/type/search filters. New captures default to inbox=true.
