The Ysra app for iOS and Android — start work in one sentence, follow it as a conversation, answer what needs you, review the output and ship it, from your phone.

On this page

The Ysra app puts the autonomous engineer in your pocket. It is built as a chat: say what to build, and Ysra works on its own — you follow it, check the output and ship it from the same conversation.

Mobile home: "What should Ysra build?" with a repository chip and a $20 budget chip, quick starts, sessions working now and sessions ready to check with Preview buttons

Home: one box, a repository and a budget.

Start work#

The app opens on What should Ysra build? — one box, a repository chip (remembered from last time) and a budget chip. Send creates the session and moves straight to the conversation; your message appears instantly and is delivered in the background.

A session started from the phone is autonomous by default: it may spend up to its budget and, once the work is verified, open a draft pull request. Destructive changes and outside writes still ask. Your account policy always wins — the phone never allows more than your account does. Where your account doesn't deliver automatically, the conversation offers Open PR.

Only real asks need you#

The drawer shows what needs you: a question, a budget stop, a plan to review. A finished-but-unverified or paused session is output to check, not an ask — so the "needs you" count stays meaningful.

Built to be safe on a phone#

  • Your sign-in is stored in the phone's secure keychain.
  • Require unlock adds biometrics or your passcode before sessions are shown.
  • Private files are fetched with your sign-in, cached on the device, and opened in the system viewer — never exposed as public links.
  • Money is shown exactly, never rounded by the phone.

What stays on the desktop#

Some jobs are deliberately desk work in the portal:

  • connecting GitHub and signing in to other services;
  • authoring workers from scratch;
  • approving a large project architecture.

The phone still shows a plan waiting for review, and lets you ask for a revision.

See Sessions on your phone for the conversation and output in detail.
