Detailed take after daily use: Flatkey AI is strongest on speed and decent on quality when the brief is clear. I tested it against two alternatives on the same tasks (blog outline, meeting notes cleanup, and a short product FAQ). Flatkey AI was the fastest and produced the least awkward tone. Weak points are edge cases — niche jargon and multi-step instructions sometimes drift. I solved that with a saved prompt style guide. Pricing is okay if you actually use it several times a week; otherwise the free tier may be enough. Overall I would recommend it to freelancers and small teams who need reliable first drafts, not final publish-ready copy every time.

Ciddi iyileştirme lazım. Yavaş, tutarsız ve destek yardımcı olmadı.

Simple, focused, and not bloated. That alone makes it stand out among AI tools.

Solid tool overall. A few rough edges, but it saves me time every week.
