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).
Not yet. Grammarly's Chrome extension is the gold standard for in-browser grammar checking; TextSight's extension is on the roadmap but not shipped. If you want grammar suggestions while writing in Gmail, Twitter, LinkedIn, etc., Grammarly currently does this 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.
