Aider
Aider is an open-source AI pair programming tool that runs in your terminal, builds a map of your whole repository for context, works with almost any LLM including local models, and commits each change to git with a written message so every edit can be diffed and undone.
- AI changes become ordinary git history — diffable, revertible and cherry-pickable with tools you already trust
- Per-commit granularity means you can keep the good changes and discard the bad ones separately
- The repo map degrades gracefully in large codebases where context-window approaches fail
- Model-agnostic, so a provider's bad quarter does not become your problem
- Terminal-only, which is a real barrier for developers who work primarily in a GUI
- Cannot see your selection, cursor, failing tests or language server errors the way an IDE agent can
- Bring-your-own-key billing has no floor and no ceiling, so spend is invisible until you check
Pieces
Pieces runs in the background on your computer forming a searchable memory of your work, capturing what you see and what you copy by default and what you hear only if you opt in. It builds a chronological timeline across Gmail, Outlook, browsers and Slack, and generates standups, briefs and recaps from real context.
- Solves a problem everyone has and almost nothing addresses
- The capture split is drawn at the line people actually care about
- Making audio opt-in while screen content is default is the right way round
- A timeline answers what happened, which search cannot
- Continuous screen capture is a large permission that deserves real thought
- Records what you saw, not what you understood, which can mislead
- Cannot capture what happened without you, which is often what matters
