The record

Style suggestions: Yes
Purpose: The online checker reviews English spelling and grammar and offers proofreading suggestions.
Checks: Free Check reviews grammar, spelling, punctuation, and contextual usage, with corrections users can review individually or apply together.
Deep Check: Deep Check is described as catching issues such as misused words, advanced punctuation, run-on sentences, tense shifts, and style issues.
English variants: The editor supports American, Australian, British, Canadian, New Zealand, and South African English.
Writing tools: The editor includes readability insights, sentence-flow analysis, word and phrase frequency, writing goals and timers, a thesaurus, translation, and a title capitalizer.
AI detector: The editor offers an experimental AI-style signal estimate and says the result is not proof of authorship.
No rewriting: Free Check does not use generative AI to rewrite text and suggests targeted corrections instead.
Account requirement: Free Check and the editor’s writing-analysis panels and supporting tools can be used without an account or sign-in.
Text limit: Free Check is limited to 10,000 characters; the editor says installing the free app enables review of longer text.
Privacy: The privacy policy says free-check text may be temporarily sent with technical metadata to third-party API providers and advises against submitting sensitive or confidential information.
Compliance: The privacy policy says data is handled within the limits of Swiss law and, where applicable, the GDPR.

Intended users: The editor describes its audience as English writers, including students, English learners, teachers, tutors, content creators, professionals, editors, and proofreaders.
