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.

Pick a mode
Open the chat panel and choose a mode: Ask to understand the code, Plan to
scope a change, Agent to let it execute, or Design to generate UI. See
Modes.
Make a change
Try: “Add input validation to the signup form and run the tests.” In Agent mode the
model reads the relevant code via the Context Bridge, edits it, and runs your tests —
no manual file-hunting.
Let it remember
Anything the agent learns about your project is written to memory and surfaces next
session, so you never re-explain your codebase. See Memory.
