Quickstart

Start with a small, disposable project or a clean branch. You will ask for a bounded change, review the proposed edit, and check the result. A model connection is required; a V3Code account is not required for BYOK.

1. Open a project

   Launch V3Code and open a folder. On first open, V3Code builds a local semantic index of the codebase — this is what lets the agent answer without reading every file.

2. Connect a model

   Use your existing provider plan, your own API key, or an available free model. Free-model capacity can change. A V3Code account is used for V3Code account features and hosted usage; it is separate from provider sign-in.

3. Pick a mode

   Open the chat panel. Choose Read to inspect without changing files, Plan to outline the work, or Agent to make a change. Design is a separate composer option. See Modes.

4. Make a change

   Try: “Read this project’s README and existing setup files. Propose one correction to the README’s setup instructions. Explain your evidence before editing, and leave all other files unchanged.” Review approval requests before allowing the edit.

5. Review and check

   Inspect the changed lines. Ask the agent to check the instructions against the actual project configuration and report what it verified. Keep the edit only if it is correct; do not treat the model’s confidence as proof.

6. Try the in-editor prediction layers

   Start typing and press Tab to accept a V3Code Tab completion. Then make a small edit and pause: V Go can prepare the likely next change point. For a whole-file draft, put the cursor near a TODO and press Shift + Tab to open a reviewable Turbo Draft.

7. Let it remember

   Ask the agent to record a confirmed project decision. In your next conversation, check that the retrieved context is accurate. See Memory.

What success looks like

You have one reviewed README change, no unrelated modified files, and an explanation of what was checked. If the model cannot connect, fix the connection first using the provider guide; repeatedly submitting the same edit request will not resolve sign-in or capacity problems.
