Capabilities

Built for how you actually work

Scope-aware intelligence

Paer reads your codebase, understands imports, types, and relationships. Suggestions are contextual, not generic.

Integrated terminal

Run commands, see output, and let the AI act on errors — all without leaving the editor. No copy-paste loops.

Tool-call transparency

Every file read, edit, and command is visible. You see exactly what the AI does — no hidden actions, no surprises.

Inline diff review

See additions and deletions rendered inline with syntax highlighting. Accept, reject, or modify changes in-place.

Session memory

Conversations persist across restarts. Branch, compare, and revisit sessions — your context is never lost.

Local-first privacy

Your code stays on your machine. Paer runs as a native desktop app — no browser, no cloud storage, no telemetry.
