The coding copilot that asks before it commits.
Describe a change in plain English. SolarGlyph Copilot reads your GitHub repository, writes the code, and shows you exactly what it will commit. Nothing lands until you approve it.
Add a card to start. You are not charged until the trial ends, and you can cancel any time before then.
Your own AI key
AI usage bills to your own Tomdacat account.
Your GitHub, your branch
It works in your repositories and nowhere else.
You choose commit safety
Ask, use an AI safety review, or commit automatically.
Passkey sign-in
Add two-step sign-in with a passkey or authenticator app.
How it works
From a sentence to a reviewed commit.
Connect your key and your repository
Paste your Tomdacat key once, sign in with GitHub, and pick a repository and branch. Your key is stored encrypted and is never shown again.
Describe what you want
Ask in plain English. Copilot reads the files it needs, explains its plan, and proposes the edits.
Choose how commits are reviewed
Ask to approve every commit, let an AI reviewer flag anything uncertain for your approval, or choose automatic commits in Settings. You can inspect the exact diff before approving a change.
Three ways to work
Decide how much leash it gets.
Plan
Think first. Copilot explores the code and proposes an approach, and changes nothing.
Agent
The everyday mode. It proposes each edit and waits for your approval before anything is committed.
Autopilot
Keeps working through a bigger task without stopping at every step. You can still stop it, and review what it did.
Always in control
No surprises, on your code or your bill.
Review before commit
A full diff and the commit message, every time, before anything is written.
Branches and pull requests
Work on a branch and open a pull request when you are ready.

Questions
The short answers.
What does “bring your own key” mean?
Copilot uses the AI models on your own Tomdacat account. You pay Tomdacat for the AI, and SolarGlyph for Copilot itself.
Do I need a card for the free trial?
Yes. You add a card and pick a plan to start. You are not charged until the trial ends, and you can cancel any time before then under Settings, then Plan & billing. After that you will not be charged.
Can Copilot change my code without asking?
No. In Agent mode every edit is shown as a diff first, and nothing is committed until you approve it. Autopilot works through bigger tasks with fewer pauses, and you can stop it at any time.
Which repositories can it see?
Only the ones you connect through GitHub, and only the repository you pick for each conversation.
Where do I see how much I have used?
On the Usage page, and in the Copilot usage pop-up inside the app. You get a heads-up when you are close to a limit.
