A digital assistant for your work communications: it reads the WhatsApp, Telegram and Microsoft Teams chats and the email you select, locally on your Mac, and answers in chat — digests, search, translation, reminders. It sends nothing without your confirmation and marks nothing as read.
Requires: macOS 13 (Ventura) or newer, Apple Silicon (M1 or newer). For now some features need a newer macOS: smart search — 14, text recognition in images — 26.4, voice transcription — 27. For WhatsApp — the WhatsApp for Mac client from the App Store (the web version and WhatsApp Business are not supported).
Open the downloaded Synpl <version>.dmg and drag Synpl into Applications.
Launch it from Launchpad or Applications. The app is signed and notarized by Apple — it opens right away, without warnings.
First launch
Terms — read and press “I accept”.
Sign in — with your work email and a one-time code, or with Microsoft: a Microsoft page opens, sign in with your work account and enter the code shown. Microsoft sign-in also connects Teams, Exchange mail and calendar; your password never reaches the app.
Voice transcription (optional) — the app offers to download a model (~574 MB, once). Voice messages are transcribed locally and never go to the server. You can skip this and enable it later on the “Connections” tab.
Connections — check the sources:
WhatsApp — on first read macOS asks for access to WhatsApp's data; press “Allow”. This grants access to the whole database; which chats are actually read, you choose on the “Chats” tab.
Telegram — press “Sign in”, enter your phone → the code from Telegram → your password (if 2FA is on). The session stays on your Mac only; in Telegram's device list it appears as “Synpl”.
Teams — connects automatically after the Microsoft sign-in.
Chats — tick the chats the assistant may read. The rest are never extracted. Press “Save selection”.
The app shows a short tour on the first visit to each screen. Skip it if you like and reopen it any time with the “?” button in the top-right corner: “Tips for this screen” or “Restart the walkthrough”.
Using it
The “Chat” tab: ask in plain words or press a quick button:
“Today's digest”, “This week” — a summary of the selected chats with reply drafts;
“what did <name> write”, “translate the last voice message from <name>”;
“what is pending on me”, “what did I promise and not do”.
Reply drafts are copied with one click, or sent from the app after you confirm the recipient and the text.
Your own data
Under Integrations you can connect your own services — with your own keys, read-only, straight from your Mac:
CRM, Jira, Zendesk — “what is going on with <client>”: the deal stage, open tickets and what your chats say about it, together;
Databases and spreadsheets (PostgreSQL, MySQL, SQLite, folders with CSV or Excel files) — the Data Analyst counts, compares and draws charts;
Knowledge base (a documents folder, Notion) — the Product Expert answers from your documents and names the source.
Keys stay on your Mac. The assistant reads and changes nothing in these services.
If something is off
“WhatsApp not found” — install WhatsApp for Mac from the App Store and launch it at least once.
Teams “no connection” — sign out and sign in with Microsoft again on the “Connections” tab.
Updates — when a new version is out, the app shows a “Version … available” banner.
All data (conversation history, sessions, cache) stays on your Mac in ~/Library/Application Support/Synployee.
