Local web UI for the Pi coding agent — browse sessions, switch worktrees, manage models, and chat beside your project files in a browser.

Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.

Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
Model Comparison: Rerun the same task against different configured models to compare output quality.
In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.
