What is Franz 6?

Franz 6 is a cross-platform desktop application that consolidates WhatsApp, Slack, Signal, Telegram, Gmail, Outlook, and 75+ other services into a single, fast workspace. Instead of juggling multiple browser tabs or separate apps, you get one unified view for all your messaging, email, and collaboration tools. The latest version introduces a built-in AI assistant that summarizes long chats, transcribes voice notes, triages your inbox, and drafts replies—all processed on-device for privacy. With over a million downloads and recognition as Product Hunt’s Desktop App of the Year 2016, Franz 6 is a mature, Vienna-built solution for serious communication work.

Who it's for

• Consultants and operators who need to move seamlessly between client messages, team chats, and email handoffs without losing context.
• Recruiters and founders who manage multiple accounts across different platforms and require a single workspace to track conversations, follow-ups, and approvals.
• Privacy-conscious professionals who want AI assistance and unified messaging without compromising data security, thanks to on-device processing and optional EU-hosted cloud.

Key features

Cross-channel workspace

Franz 6 displays every service—WhatsApp, Slack, Gmail, Signal, Discord, Telegram, and more—in one working view. Each service runs in its own isolated container, so you get unified notifications and unread badges across all channels without cross-contamination. You can even add any website as a custom service.

Cross-channel AI assistant

The built-in AI can catch you up across email, WhatsApp, Slack, and Signal simultaneously. It summarizes threads, transcribes voice notes, and drafts replies with the right context already attached. All processing happens on-device by default, with optional Franz Cloud or your own API key for flexibility.

Franz Mail

Email is treated as part of the same workflow, not a separate chore. Franz Mail offers a priority inbox, sender intelligence, and local search that understands your work context. It neutralizes tracking pixels before they can report back, keeping your reading habits private.

Native Signal integration

Signal runs natively inside Franz 6, with support for voice note transcription, thread summaries, and action items. Sensitive conversations stay inside the same workflow while benefiting from the same AI features available across other services.

What stands out

"Franz is built to help you work faster, not to watch you work."

This philosophy drives every design decision. Unlike many productivity tools that monetize user data, Franz blocks trackers, kills email pixels, and keeps secrets encrypted. The AI runs locally on your device by default, and the optional cloud is hosted in France with zero retention. You get the speed of a unified workspace without sacrificing privacy—a rare combination in today’s messaging landscape.

Worth checking out if…

You manage multiple messaging and email accounts across different platforms and want a single, privacy-respecting desktop app to handle them all. Franz 6 is especially valuable if you need AI assistance for summarizing conversations and drafting replies, but refuse to trade your data for that convenience. It’s also ideal for teams or individuals who rely on Signal for sensitive communications and want native support without leaving their main workflow.
