Ask about a Beta invitation

Access

Request an invitation.

Email Solen support. If access is available, we will send you an invitation code. Solen stays locked until a code activates your account.

Sign in

Create your account.

After installing, create an account with your email and enter the short sign-in code Solen sends you. Then redeem the invitation code in Settings.

AI allowance

Included once.

The Beta itself is free. An invitation may include a one-time amount for online AI use through Solen. Any unused amount stays available until used; it does not refresh monthly. When it runs out, those online AI requests stop. There is no Beta subscription or checkout.

Check before opening

Verify the file.

The current Beta installer is not signed with a Windows publisher certificate, so Windows may show a security warning. Its SHA-256 lets you check that the downloaded file matches the value shown above, but it does not verify the publisher's identity. If you are not comfortable running unsigned software, wait for a signed installer.

Updates

Solen keeps itself current.

Once installed, Solen checks for new Beta versions, downloads them in the background, checks them, and asks you to restart to finish. If you installed Solen 0.9.0, install this version once from this page; later versions then update themselves.

0.9.8-beta.21

Diagrams draw again.

A diagram that builds up step by step failed to draw in the last beta. It draws now, and a figure Solen can’t draw says so within a few seconds.

Endings

A run that stops short says so.

When Solen stops without being sure, it shows its ending straight away instead of waiting on Carry on.

Questions

Long questions keep their buttons in reach.

However long the question, its answer buttons stay where you can press them.

Asking

The ask bubble closes itself.

Hold Ctrl + Alt and don’t use the bubble, and it goes away after a few seconds.

Fixes

Small fixes.

Wording, alignment and screen-reader names in Setup and Settings.

Going back

Going back is manual.

Returning to 0.9.8-beta.20 means reinstalling it yourself.

Installing

Check your PC first.

This build is for 64-bit Windows 11 on a PC that is yours. It has been tried on Windows 11 only: Windows 10 and ARM PCs are untested.

Screenshots

Saved on your computer.

Screenshots are stored unencrypted. When another capture is saved, Solen tries to remove captures older than seven days and keep at most 100. If no later capture triggers cleanup, older files can remain longer. Screenshots may include private details, including sign-in screens. See what stays on your computer.

After uninstalling

Remove local data yourself.

Uninstalling leaves Solen's local data in %LOCALAPPDATA%\Relay. Open File Explorer, enter %LOCALAPPDATA% in the address bar, then delete the Relay folder if you want to remove those files. Read the privacy policy.

Feedback

Tell us what happened.

Settings → Feedback sends us what you write, with the app and Windows versions — nothing else is attached. The Export diagnostics action creates a report on your computer; it is not sent automatically. What feedback includes.
