WhaGrOU
Stay personally connected on WhatsApp — reconnect with people you've lost touch with, remember who everyone is, and reach group members one‑to‑one. In your own voice.
What it does
🌱 Reconnect
It quietly finds people you haven't spoken to in a while — a balanced mix of recent and long‑lost — and writes each one a short, warm message picking up a real thread.
🧠 Remember
Every contact gets a living profile: who they are, their language, the way you write to them, your shared history, and a little note so you always know who's who.
💬 Invite personally
Pick a group, say what you want — "invite everyone to Sunday" — and it drafts an individual 1:1 for each member. Not a broadcast. A personal note to each.
How it works
Link WhatsApp — scan a QR once, the same way as WhatsApp Web. Your messages stay on your computer; there's no server.
It learns your voice — from your own past messages, so drafts sound like you (your greetings, your length, your emoji) and in each person's language.
You review — read each draft, edit anything, approve the good ones, skip the rest. You're always in control.
It sends, gently — approved messages go out one at a time with natural pauses and a daily limit. No spam, no blasting.
Install on Mac
1. Download WhaGrOU-2.0.0-arm64-mac.zip and unzip it. Drag WhaGrOU into your Applications folder.
2. The first time, macOS may say it's from an unidentified developer. Right‑click the app → Open → Open. (You only do this once.)
If it still won't open, open Terminal and run: xattr -dr com.apple.quarantine /Applications/WhaGrOU.app
Windows
A Windows version is on the way. WhaGrOU is built to run on Windows too — we just need to produce and test the Windows build. Want it first? Let us know and we'll prioritise it.
What it costs
WhaGrOU is free. The only cost is the AI that writes the drafts — billed by Anthropic to your own key, and it's small. There's no subscription, and you pay only for what you use.
~1¢
per draft
~$0.50–1.50
a batch of 50 reconnections
~$2–6/mo
reaching ~50–100 people a week
Profiles are built only when you actually message someone, so you never pay up front. Full cost breakdown →
Your privacy
WhaGrOU runs entirely on your own computer. Your contacts, chats, and drafts live in a local file on your Mac — there is no WhaGrOU server and nothing is uploaded. Drafting uses your own AI key. You decide what gets sent, and to whom.
