One app for you and your AI — private by design, honest about what works today, and already Eleanor's home as she grows.
By downloading, you accept the Terms of Use.

Use the web app meanwhile →In final preparation. Companion on your phone, with the same boundaries you set at home.

You can talk to her on the web today. Her voice and deeper memory arrive in Companion as they're ready — everything you set up is already hers.
Every build we publish comes with a fingerprint (a SHA-256 checksum). If the fingerprint of the file you downloaded matches the one below, it's byte-for-byte the file we shipped. Most people never need this — it's here because you should always be able to check.
On Windows: open PowerShell, type Get-FileHash followed by a space, drag the downloaded file into the window, and press Enter. Compare the result with the fingerprint above.
