MADE FOR THIS FORMAT
Retry without duplication
Use an Idempotency-Key when creating a task. Poll existing tasks after a connection interruption instead of uploading again.
Try before you integrate
Trial keys last up to 24 hours. The trial allows 20 tasks per visitor per day and 2 active tasks, subject to total capacity. No paid subscription is currently offered.
Before you upload
How is the file handled?
Files are processed on our managed servers, without sending document content to third-party LLM APIs. Completed task data is automatically cleaned up after 24 hours; active tasks follow the retention policy.
Can I recover the original information?
Blackout and placeholders do not include a restoration map. Keep your original file separately.
Will every sensitive detail be found?
Automatic detection can miss information. Inspect the output before sharing, especially handwriting, poor scans and unusual layouts.
