UnderCurrent Soloweb beta

The web beta runs in Google Chrome

Open this page in Chrome on a Windows or Mac computer.

During a call Solo floats a small strip over your meeting. That needs a Chrome feature other browsers don't all have yet.

    There is also UnderCurrent Solo for Windows, a desktop app in an invitation-only beta. Write to feedback@undercur.com to ask about it.

    Your email

    The web beta includes three free 40-minute sessions per person. We ask for your email to make sure each person gets three. We will also need permission for your microphone and webcam, when a popup comes on - please approve it. Nothing is saved or sent.

    Before we send your code

    What we keep: a one-way fingerprint of your address, how many of its three free sessions have been used, and which terms you agreed to. Not the address itself. Resend, which sends the code, keeps a copy of that email for 30 days, then deletes it.

    Check your email

    We sent a 6-digit code.

    The code expires in 10 minutes.

    Beta tester code

    Testers get unlimited sessions. Enter the code you were given.

    Before you use the code

    Testers can also sign in with their email: a tester's address is recognised after the usual code check.

    Your camera and microphone

    Solo coaches on your voice and your face. Allow both now, so the strip can start the moment you say you're ready.

    It stays on top of Zoom, Teams or Meet. Keep this tab open: closing it ends the session.

    Camera and microphone

    Use headphones if you can, or keep your microphone and your call audio on the same device, so Solo hears only you.

    On by default. Off means nothing is sent.
    Exactly what is sent

    One small message when Solo opens, when a session starts and when it ends: event, app version, chrome, windows or macos, camera on or off, the session length in bands (0–5, 5–15, 15–30, 30–40 minutes), whether it reached the limit, and three yes/no flags: first time today, this month, ever. Never your email, a name, an identifier, your address or anything Solo heard or saw.

    Account

    We keep a one-way fingerprint of your address and how many of its free sessions are used, until 30 days after the web beta ends. Resend, which sends the code, keeps a copy of that email for 30 days. To have both deleted sooner, write to privacy@undercur.com from that address.

    Tell us how it's going

    There's no feedback form, because a form would mean sending something. This opens your own email app with a message already written, which you can read, edit or throw away. Nothing is sent unless you press send.
