One room holds the whole session.
- One sun for everyone
- Start a focus block and the sun starts sinking for the whole room. When it sets, the room moves to a break, with a longer one after every fourth block.
- Your group on camera, encrypted
- Video and voice are encrypted and go directly between browsers over WebRTC. Flow’s servers never see or store them. Mute or turn the camera off whenever you like.
- A task list you finish together
- Add goals for the session, assign them to people, and watch the room’s progress fill in.
- Chat, with a study assistant
- Message the room, or start a message with /ai to ask a question without leaving.
- Sound for concentration
- Rain, ocean, a fireplace, wind, a quiet night. Share a YouTube or Spotify link when the room wants music.
- Open study groups
- List your room on the board and people studying the same thing can take a seat. Groups hold two to six.
From a link to your first focus block.
Create a room
You get a six-character code. Add a PIN if you want the room private.
Share the link
Your friends open it, sign in, and land in the same room.
Start the timer
Twenty-five minutes of focus, then a break. Change the lengths whenever you need to.
Pick your sky.
Ten skies, from a forest dusk to plain daylight. Choose one and this page changes with it. Your room will match.
Open source, start to finish.
