ChatExhibits turns a WhatsApp chat export into a court-ready PDF: every message numbered, Bates numbering, a SHA-256 integrity certificate with the source ZIP embedded, photos in a numbered appendix and voice notes transcribed for your review. Everything runs in your browser: no server, no account, no upload. The parser is deterministic, not an LLM, so every word stays exactly as sent. Free unlimited preview on your real export.
