Still the smoothest inline correction across every app, and the free tier covers most people. But generative models ate its rewrite features — Premium is hard to justify if you already pay for ChatGPT or Claude.
Known limitations
- Suggestions can flatten personal voice into corporate beige.
- Premium overlaps with what free LLM chats now do.
- Occasional confidently-wrong grammar calls.
- Business plan retired; parent company renamed Superhuman (2025-10).
