About

Sinceerly is a lightweight AI-powered “humanizer” designed to reverse the polished, formulaic tone of AI-generated writing and make emails feel more natural, imperfect, and authentically human. Positioned as the opposite of traditional writing assistants, it integrates directly into Gmail as a Chrome extension, allowing users to draft emails normally and then transform them with a single click. It focuses on removing common AI writing signals, such as em dashes, repetitive phrases like “not just…,” and overly structured language, replacing them with simpler wording, abbreviations, and intentional imperfections. It introduces controlled variability through a single slider with three intensity levels, each progressively altering tone, structure, and formatting to mimic real-world communication styles. Users can preview all edits through highlighted changes and selectively apply them, maintaining control over the final message.

Pros & Cons from Real Users

Pros

  • It literally helps avoid mistakes and generally makes your document interesting. it's grammar checker is also good.
  • I've looked at a lot of the AI writing tools out there, and found Quillbot to offer a lot of features for their pricing. The software rewrites content very well and allows you to expand upon text used.

Cons

  • It is a great tool, i don't really see any problem with it.
  • The interface could be nicer and the speed of rewriting / rephrasing could be faster. But overall it's very good.
