Sign in and create a workspace

  1. Sign in at twill.ai/login with GitHub or Google.
  2. Name your workspace and pick a URL slug.
2

Connect GitHub

From your workspace home, install the Twill GitHub App and choose which repositories it can access. Twill clones every connected repo into one shared dev environment, so connect all the repos that make up your stack — the agent decides which ones a task touches.
3

Create your first task

Describe a change the way you’d hand it to a teammate. Start small, with a clear before/after, so the first PR is easy to judge:
Fix the empty state on the settings page: show a link to create the first workspace.
Twill reads the relevant code and asks clarifying questions if the request is ambiguous.
Before the first real task, click Set up dev environment on the home screen. Twill installs dependencies and starts your dev servers once, and every future task starts from that working state — which is what makes runtime verification possible.

Review the pull request

You get a PR with the change plus whatever proof applies to your repo: test output, logs, screenshots, or a screen recording.
Nothing merges automatically. You review Twill’s work like any other PR.
