Team communication made easy, and kept private.

Fern is one app where your company chats, calls, shares screens and sends files. Your admins stay in control of it.

  • What Fern is

    A team chat app for companies: direct chats, groups, voice and video calls, screen sharing and file sharing in one place.

  • Easy for everyone

    Chats, calls and files sit together, so nobody has to switch between tools. The same conversations follow you from desktop to Android.

  • Privacy at the centre

    Privacy mode frosts messages on screen, notification previews can hide their content, and calls connect directly between participants.

06 Calls

Voice, video and screen sharing

Calls connect directly between participants over WebRTC. The call opens in its own window with a tile per participant, and a compact call bar stays in the main window so you can keep chatting. Record a call, switch to focus layout, pop a participant out, go full screen, and choose devices, voice suppression and video quality.

  • Voice
  • Video
  • Screen sharing
  • Record a call
  • Full screen
  • Start from any chat with the phone or camera button in the header.
  • Live screen sharing for walkthroughs and reviews.
  • On-demand coordination: the call coordinator only runs while a call is active and switches off after the last call ends.
  • Live now lists calls you can join in your conversations.

03 Deployment

Three ways to run Fern.

Pick where your conversations live: hosted by us, held in your own infrastructure, or passed directly between devices.

Available today

Fern Cloud

We run it for you

  • Fern hosts the server, database and file storage.
  • Nothing to install beyond the desktop app.
  • Updates roll out automatically.
  • Sized by plan (see Plans).

Best for teams that want to start this week.

Your database, your storage

You hold the data

  • Connect your own database so chats are stored in your account.
  • Connect your own storage service for files, voice messages and call recordings.
  • Fern provides the app and the coordination; your data stays in infrastructure you own.
  • Offered on the Enterprise plan.

Best for companies with data-residency or compliance rules.

Live for calls

Peer-to-peer

Device to device

  • Voice, video and screen sharing connect directly between participants.
  • Call media never passes through a central server; signaling carries no audio or video.
  • Next: peer-to-peer messaging, so chats travel device to device as well.
  • Works alongside the other two modes.

Best for small teams that want the least data held anywhere.

04 Security & privacy

Private by design, and honest about what is live.

Privacy runs through the whole product: controls your team uses every day, and deeper protection arriving in the next releases. The two are kept apart below.
