A weekend of muscle memory pays off for years.
Plugins and themes from huge community ecosystems.
Plain-text Markdown keeps your content portable forever.
Hands stay on keys; the mouse becomes optional.
Customize prompts, tools, and behavior; no black box.
Every change is a reviewable diff — you stay in control.
Swap between frontier APIs and local models per task.
Lives where you work: VS Code, JetBrains, Neovim, or plain terminal.
Download the source and move into the project folder.

# see README for the exact launch commandIt is an open-source project at purocean/yn with 922 forks. Check the repo's contributors and recent commits to see how active maintenance is.
AGPL-3.0 — free to use, including over a network, with source-sharing obligations.
VS Code and terminal are universal; check each tool for JetBrains/Neovim.
With local models, no. With APIs, check the provider's retention policy.
Cloud frontier models code best today; local keeps everything private and free.
