Submission insurance for real life
Upload it before they reject it.
Three minutes before “Submit” can save three weeks after “Rejected.”
Think of it as submission insurance: a final check for missing signatures, attachments, contradictions, deadlines, and other rejection risks before you send.

Preflight check
Check my submission
Try Preflight free. No account. No card.
Your basic Preflight check happens locally in your browser.
Upload your submission
Documents, images, audio and video. Browser and codec support varies; media checks stay local and files over 500 MB are not opened.
Audio and video receive a technical readiness check for things like format, duration, silence, clipping, dimensions and playback problems.
Handwritten documents? You can try them too. Clear handwriting works best, and Preflight will warn you when OCR confidence is low.

Technical submission readiness
This checks whether the file itself appears ready to submit. It does not currently evaluate what is said in the recording.
Speech transcription and spoken-content review are not currently offered. Audio and video stay on your device.

Handwriting or low-confidence OCR
Handwriting detected or OCR confidence is low. Please check the extracted text before relying on this result. Corrections stay in this browser and are used only when you rerun the basic Preflight.

One document or fifty. If someone else is going to review it, Preflight it first.
Preflight looks for submission risks such as missing information, signatures, attachments, inconsistent details, dates, deadlines, and other potential problems before you send. It does not guarantee acceptance or replace professional advice.
Not sure if Preflight is for this? If you’re about to submit it for someone else to review, it probably is.
How it works
Three minutes before “Submit” can save three weeks after “Rejected.”
Fix rejection risks
Preflight surfaces blanks, signatures, conflicting fields, likely missing attachments, and deadlines.
Run it again
Make the fixes, rerun the check, and submit with fewer preventable mistakes.
Privacy by architecture
Your submission is not our product.
The basic checker processes extracted document text in your browser. Preflight does not need an account or a server copy of your files to perform the basic check.
Deep Review is optional and clearly labeled. If enabled, only extracted text needed for the review is transmitted. See the privacy policy.

FAQ
Is Preflight insurance?
No. “Submission insurance” is a metaphor for prevention. Preflight is software that checks documents and submission packets for potential problems. It does not issue insurance policies, guarantee acceptance, or reimburse losses.
