What does Franz Messenger do?
Franz Messenger is a desktop app that brings all your messaging services into one window. It supports over 75 services including WhatsApp, Slack, Gmail, Signal, Discord, Telegram, and Microsoft Teams. Each service runs in its own isolated container, so you can stay logged into multiple accounts at once without constant sign-ins. The app shows unified notifications and unread badges across all your channels, and you can even add any website as a custom service.
What makes Franz Messenger different is its AI assistant and cross-channel features. The AI can search across your email, WhatsApp, Signal, and Slack messages to find specific conversations or catch you up on what you missed. It drafts replies with the right context already attached. Franz Mail gives you a priority inbox with sender intelligence, so formal handoffs and approvals don't get lost. The app also includes native Signal support with voice note transcription, thread summaries, and action items. You can group services into workspaces by mode or priority, run two services side by side in one tab, and turn messages into tasks with a built-in manager.
Franz Messenger is built for people who move between multiple messaging platforms all day — consultants juggling client chat and team chat, recruiters tracking candidates across channels, founders managing investor conversations, and operators handling handoffs between email and Slack. The app runs on Mac and Windows, with AI options that include local on-device processing, cloud, or your own API key. Privacy features include tracker blocking, email pixel neutralization, and end-to-end encryption for Signal.
