Typeahead

Typeahead is a native AI auto-completion tool for macOS.

That provides inline continuation suggestions for content being typed across almost any Mac app, making everyday text input like emails, Slack messages, Notion documents, editor instructions, ticket replies, and research notes completed faster. It runs as a native Mac app, supports Tab suggestions, and operates in a straightforward and natural way; The built-in model processes text locally, does not rely on cloud generation, requires no account, and does not perform telemetry, making it suitable for users who value privacy, offline usability, and writing efficiency. After a period of use, the software gradually adapts to personal expression habits, making the content more user-friendly rather than the rigid tone of a general robot. With GPU acceleration and a lightweight design, Typeahead is suitable for high-frequency email writers, developers, writers, support teams, researchers, and non-native writers, helping to reduce repeated input, fill in common expressions, improve sentence fluency, and save a lot of typing time.
