Free LLM grammar check vs the $144/year industry standard. Where each one wins, when to pick which.
If you write in many places (Gmail, Word, Slack, LinkedIn) and want grammar suggestions everywhere with real-time underlines, Grammarly Premium is worth the $144/year — its desktop apps and browser extensions are unmatched.
If you mostly write in web apps and want a clean, LLM-quality check on a finished draft, TextSight is the same quality at $0 — and the click-to-accept-each-fix UX gives you finer control than Grammarly's bulk-accept flow.
Bloggers, students, writers who copy-paste their draft into a checker before publishing. The 5-15s LLM round trip is fine for finished drafts. Saves $144/year.
Professionals writing in Gmail + Slack + Word + LinkedIn all day. The browser extension and Word add-in are genuinely good. Worth the $144/year if writing volume is high.
Grammarly catches typos as you write. TextSight catches the issues Grammarly missed when you do a final pre-publish review. They're not mutually exclusive.
Yes. 5 checks per day with no signup. Sign in (free account) for 50/day. No credit card required at any tier. Grammarly's free tier exists too but is heavily limited compared to Premium ($12/month).
Three scenarios: (1) you write in Word, Slack, Gmail, and many other apps and want grammar checking everywhere — Grammarly's desktop app + browser extensions + Word add-in are unmatched; (2) you need real-time as-you-type underlines instead of click-to-check; (3) you write business documents and need tone detection. For pure web-based grammar checking on finished drafts, TextSight is the same quality at $0.
For longer-form writing, yes — generally fewer false positives. Rule-based checkers flag every long sentence and every passive voice as a "style issue" because they can't see context. LLMs only flag issues that actually hurt readability. The trade-off is speed: 5-15 seconds per check instead of instant.
Grammarly Premium's plagiarism check runs against ProQuest's database — paid, web-indexed, real plagiarism detection. TextSight ships a "Plagiarism Risk Analyzer" (free) that flags clichéd phrasings and uncited specifics — different product, honest framing. For real plagiarism detection, use Copyleaks/Quetext/Turnitin (or Grammarly Premium).
Yes, but it does a different job. TextSight: AI Detector & Humanizer is on the Chrome Web Store: select text on any page and it scores how AI the writing reads, then rewrites the sentences that give it away. It is not a live grammar checker and does not correct you as you type, so for grammar suggestions while writing in Gmail, Twitter or LinkedIn, Grammarly still does that better.
Yes. Grammarly for everywhere-real-time, TextSight for the focused web-based "I want a clean LLM check on this draft" moment. They serve different points in the writing flow — they're not mutually exclusive.
