Editor's Review
Grammarly in 2026 has an identity crisis: it acquired Superhuman Mail (July 2025) and rebranded the entire parent company to Superhuman (October 2025) — "Grammarly" now survives only as a product name alongside Superhuman Docs (the former Coda) and Superhuman Go. Pricing: Free (basic grammar, 100 AI prompts/month); Pro $12/month billed annually ($144/year) — but $30 month-to-month, a billing gap that traps the inattentive; the $144 hits upfront after trials. Superhuman Business bundles Grammarly Pro + Mail + Docs at $33/member/month. Enterprise is custom.
The 2026 scandal worth knowing: Grammarly pulled its "Expert Review" AI feature after a class-action lawsuit filed March 2026 (journalist Julia Angwin, S.D.N.Y., damages over $5M) alleging it used writers' names and identities without consent to mimic author styles; CEO Shishir Mehrotra apologized on LinkedIn. The company cites 40M+ daily users, $700M+ annual revenue, $13B valuation.
Who should pay? Professionals whose writing is the work product and who want plagiarism plus AI-text detection in one subscription — the Pro bundle is still the most complete. Who shouldn't? Anyone on a budget: Microsoft Editor ships free with 365 and Apple Intelligence writing tools ship free with the OS — bundling is the existential threat, and the moat is thinning. For writers specifically, ProWritingAid at $10/month annual or $399 lifetime breaks even against Grammarly Pro in ~2.8 years; Grammarly is subscription-only forever. Watch the $30→$12 monthly/annual gap — it's the oldest trick in the book.
