AI coding gets messy when the project loses context.

The problem is not that AI cannot write code. The problem is that it forgets the real shape of your project, misses recent changes, guesses at file relationships, and burns your time re-explaining the same work.

Context drift

Stop re-orienting every session

Fsidecar keeps project state, recent work, and focused files visible so your next prompt starts closer to reality.

Safe refactors

Preview before files change

Inspect source ranges, proposed helper drafts, and future-state previews before committing to edits.

Local-first

Your project stays on your machine

Fsidecar is designed around local project awareness, deterministic workflows, and user-controlled execution.

A workbench for AI-assisted development.

Fsidecar is not just memory. It is a project alignment layer: capture what matters, focus the right files, guide the next step, and stage safer code changes.

Project-aware Work Focus with active files, recent changes, and viewer context.
Guided refactor workflow: Candidate Review → Source Preview → Extraction Preview → Apply Plan.
Preview sandbox for proposed future files without modifying your repo.
Local memory and project context designed to reduce repeated explanation.
Built for developers using ChatGPT, Claude, Codex, Cursor, Copilot, or other AI coding tools.
