Wordtune

  • Wordtune (AI21 Labs, Tel Aviv & SF, 2020)

    Status: Active (spun out of AI21 Labs 2020 by Ori Goshen/Amnon Shashua-adjacent founding team; AI21 Labs Jamba models back the rewrite engine; wordtune.com + Chrome/Edge/Safari extension + Word add-in + iOS/Android reachable 2026-08, no discontinuation — note: AI21 has slowed net-new feature dev, product in maintenance-leaning mode). Category ai-productivity-data; pipeline_stage=none. Not a grammar checker, not a from-scratch generator​ — it is a sentence-level AI rewriter + tone shifter​ that gives 5–10 alternative phrasings per selection, plus Spices (enrichment) and Read (summarizer) as satellites.

    1. Introduction

    Wordtune highlights a sentence (or paragraph) in Gmail, Google Docs, LinkedIn, Slack web, or its own editor and returns multiple rewrites filtered by Casual / Formal / Shorten / Expand, each preserving meaning but shifting register. Underneath: AI21 Jamba/Instruct family + heuristic alignment, not a chatbot. Wordtune Spices​ injects examples, statistics, counterarguments, transitions; Wordtune Read​ summarizes URLs/PDFs/YouTube transcripts to bullets with follow-up Q&A. It is the “I wrote it, make it sound human” layer — stronger than Grammarly on natural rephrase, weaker than QuillBot on bulk paraphrasing modes, not a substitute for Grammarly’s error-catching or ChatGPT’s open drafting.

    2. Core Features

    Layer Capability Notes
    Sentence rewrite​ 5–10 alternatives per selection, meaning-preserved Core differentiator vs Grammarly’s 1-suggestion
    Tone control​ Casual ↔ Formal, Shorten, Expand Toggle-driven, not prompt-driven
    Spices​ Add example / statistic / counterargument / joke / transition in-place Unlimited tier only
    Read (summarizer)​ URL/PDF/YouTube → bullets + Q&A Secondary feature, not core draw
    Translator​ Non-English → natural English (ja/es/fr/etc input) Rewrite is English-first
    Editor + extensions​ Web editor, Chrome/Edge/Safari/Firefox, Word add-in, iOS/Android Inline in Gmail/Docs/Outlook web
    Grammar​ Light spell/grammar on free; not​ a Grammarly replacement No plagiarism check ever

    5. Reviews (2026)

    • Aggregate: 4.3–4.6/5 across G2/Capterra (~278–13k reviews depending on aggregator); PCMag: “shines on rewrite, weak on grammar”.
    • Strengths cited: most natural sentence rephrases of any rewriter; tone toggle actually shifts register; extension works everywhere; non-native speakers gain fluency fast.
    • Gripes: free 10/day too tight; not a grammar checker​ (pair with Grammarly); no plagiarism; Spices only on top tier; sentence/paragraph scope only (no doc-wide consistency); AI21 slowed feature dev; mobile < desktop; occasional extension stale-reload bugs.
    • Verdict: best-in-class style rewriter, mid-pack writing assistant. Buy it for “make my sentence land”, not “proof my essay”.
