Private WhatsApp chat archive & PDF — processed only on your device
ChatKeep turns a WhatsApp chat export into a searchable archive and a clean, printable PDF. Everything — parsing, full-text search, filters, and PDF generation — runs locally in your browser. Nothing is uploaded, and there is no account, login, OAuth, or password. Free to open and search; a one-time US$12 Pro unlock removes the 20-message PDF cap and watermark.
