Caret

Caret provides an on‑screen AI assistant that can be invoked with a single Tab press in any macOS application. When activated, it reads the current window and offers text completions, suggestions, or continuations based on the surrounding context. The tool remains continuously running, building a memory of the user’s activity to improve its responses over time.

The software is aimed at users who type frequently on a Mac and want AI‑driven assistance without switching to a separate chat or editor. Because it works across all apps, it can be used for drafting emails, writing code, composing documents, or any other text‑heavy task that benefits from predictive completion.

Caret distinguishes itself by operating at the system level, monitoring the screen and providing context‑aware completions directly where the user types, rather than requiring a dedicated interface. It is distributed as a macOS 26+ application and is currently in an experimental stage.
