Friend invite only. This gate stops casual visitors — it is not cryptography. Your chat still never leaves your device once you are in.
Your chat never leaves this device. Free means import a WhatsApp, Telegram or .txt chat export, or try the sample. Everything parses and scores in your browser. No account, no cloud upload of message text — only optional localStorage for the last score snapshot.
This Telegram export has several chats. Choose the one-on-one chat you want to look at.
Your file stays on this device. It’s opened and scored right here in your browser and never uploaded anywhere.
Exporting needs Telegram Desktop, the free computer app from desktop.telegram.org. The Telegram phone apps and the separate “Telegram for macOS” app from the App Store don’t have this export, so use Telegram Desktop.
result.json file here. To use it on your phone, move it over first (for example with AirDrop or iCloud Drive).Already exported as HTML? That works too: select all the messages.html files at once, or a .zip of the export folder.
Download the installer, open the DMG, then double-click Install Relationship Companion. It’s signed with an Apple Developer ID and notarized by Apple, so macOS opens it normally.
Version 1.7: phone connects with a Mac link code + 6-digit code over the encrypted relay (no LAN / Mac.local). Also includes 1.6: live sync from WhatsApp for Mac as well as iMessage — pick the source with the iMessage / WhatsApp toggle in the Mac Live Sync card. Also includes 1.5’s security update: each phone or browser connects to your Mac once with a 6-digit code shown on the Mac, and optional end‑to‑end encrypted access for when you’re away from home (off until you turn it on). Installing over an older version keeps your settings, sharing link and connected devices.
One-time: if chats look empty, macOS needs your permission to read Messages (and WhatsApp, if you use it) —
System Settings → Privacy & Security → Full Disk Access → enable /usr/bin/python3.
Live iMessage and WhatsApp stay on your Wi‑Fi; nothing uploads unless you turn on the end‑to‑end encrypted live share or away access.
On the Mac running Live Sync, open http://127.0.0.1:8788, copy the 6-digit Connect code, then tap Connect my Mac and enter it here. Chats sync over an end‑to‑end encrypted relay — no Mac.local address needed.
