Built so that nothing is lost, nothing is changed
A faithful record of what was on your screen, with the evidence of its own integrity.
AI that reads your messages
On-device AI (Apple Vision) reads a screen recording or screenshots. Nothing is uploaded.
Never retouched
What was read stays as read, next to the original image. Corrections are added as annotations.
Sealed and verifiable
A SHA-256 fingerprint for every file, listed in a certificate.
Nothing goes missing silently
Gaps in the conversation are flagged right in the record.
Every format you need
PDF, chat-bubble PDF, CSV, TXT, HTML and JSON.
Exact export
WhatsApp, Telegram and LINE export files are imported as they are: original text and times.
How it works
Four steps, all on your device.
Capture the conversation
Record your screen while you scroll slowly through the chat (most reliable), or take a series of screenshots. For WhatsApp, Telegram and LINE, you can instead share the exact export file.
Analysis on your device
Convoseal reads each message with Apple’s text recognition, follows the scroll to avoid duplicates, and flags any gap. Keep the app open while it works.
Review
Tell the app which side is you, and check the few uncertain messages against the original excerpt. Every correction is logged.
A complete record
A PDF with numbered messages, dates and annexes of the original images, plus a certificate with the SHA-256 fingerprint of each file. Also available as CSV, TXT and HTML.
A look inside a real record
A cover page with the details of the record, then numbered, dated messages. Fictional sample.
- Numbered, timestamped messages
- Annexes with the original images
- A certificate with the SHA-256 fingerprint of each file
Screens from the app
Your conversations never leave your device
Messages are sensitive. Convoseal was designed so that we never see them.
Processed on the device
Reading, layout and PDF creation all run on your iPhone or iPad, offline.
No account, no ads
Nothing to sign up for. No advertising, no analytics, no tracking.
You stay in control
Records are stored on your device. Deleting originals from Photos is optional and always asks for your confirmation.
