Isn’t the export file enough?

Often, yes. For a small uncontested case, the export or screenshots may be enough. ConvoKeep helps with long conversations, selected passages with context, third-party privacy and numbered references. Keep the original export.

Does this prove the chat is real?

No. The integrity page records fingerprints of the file you loaded and the rendered transcript so changes can be checked. It cannot establish authenticity, completeness or what happened before export. Keep the original device and file. A court or agency decides what it accepts.

Where does my chat go?

Nowhere. Your browser reads the export and builds the PDF on your device. No message or attachment is uploaded. No messenger login or account is needed.

Why not just paste it into an AI chat?

You can, and for a short chat an AI may copy the messages correctly. Two things differ. Long exports may not fit: a two-year, 30,000-message chat is over a million tokens, more than some AI chats accept in one go, so it may have to be cut into parts and the answers joined by hand. And an AI answer is new text with no way for another person to check it against your original file. ConvoKeep works in your browser, never uploads your file, and prints the messages from the file itself with their dates and a SHA-256 fingerprint of the original.

Which chat exports can I use?

Use an exported file from WhatsApp, KakaoTalk, LINE, Telegram, Instagram, Facebook Messenger or iMessage. The guides below explain the export formats.

Can I preview before paying?

Yes. The free preview shows the first 3 pages with a watermark. Saving the full PDF requires a one-time purchase.

Can I remove private messages?

Yes. Select a date range, rename participants and redact individual messages before creating your PDF. Redacted text is removed from the PDF.

Are right-to-left scripts (RTL) supported?

No. Right-to-left scripts such as Arabic and Hebrew are not currently supported.

How can I check that nothing is uploaded?

Airplane-mode test: open the page once, turn off the internet, make the PDF — it still works, because no chat or attachment is uploaded. Keep the tab open; reloading or reopening the page offline is not supported. First visit and offline preparation, payment, license activation/revalidation and optional AI features need a connection; let preparation finish before disconnecting.

Turn your chat export into a PDF for submission. Keep the original untouched.

Prepare a PDF for a dispute or report: keep surrounding messages, hide third parties, and include a fingerprint to compare with your export. Your original stays untouched. No chat or attachment is uploaded.

Synthetic raw export: the same seven messages with context and a photo placeholder, without PDF page or message numbers or redaction. — Printed .txt excerpt

Synthetic paid Record excerpt: numbered page and messages, surrounding context, redaction marker, omitted count and source fingerprint detail. — ConvoKeep Record PDF

Synthetic paid-version example. Both sides show the same seven messages, including surrounding context; export formats vary. The Record side combines the actual PDF page with omission and integrity details.

Step 1 of 3

Paid version

1. Before: the whole chat
2. Search, then narrow the dates
3. After: a PDF of just the key messages

What the record shows, and what it does not.

You can tell if it changed

The PDF carries a fingerprint (SHA-256) of your original file and of the text. If even one character changes later, /verify shows it.

What it cannot prove

A fingerprint cannot show that a chat is genuine or that nothing is missing. Keep your original file.

Nothing is uploaded

Your chat and attachments never leave your device. Check for yourself: open the page, turn off the internet, then make a PDF.

Prepared for submission; acceptance is decided by the court or agency. Not legal advice.
