What it does

Everything inside Grammar Fixer.

Review-and-approve error cards

Every issue appears as a card showing the exact wrong text, the suggested fix, a plain-English explanation of the rule, its type (grammar, spelling, punctuation, or style), and an AI confidence badge. Fix or skip each one individually, or Fix All, Skip All, and Undo All, with pending and resolved tabs plus type filters to work through them.

5 fix modes × 6 writing styles

Target everything or just grammar, spelling, punctuation, or style, and tune strictness to General, Formal, Casual, Academic, Business, or Creative, the AI preserves a casual or creative voice instead of flattening it.

Live streaming corrections

The corrected text streams onto the screen word by word the moment checking starts, so you see results immediately instead of staring at a spinner.

Deep writing analytics

Each check returns a readability percentage, Flesch-Kincaid grade level, passive-voice count, word and sentence stats, top word-frequency chips, and a 4-part writing quality score (clarity, conciseness, engagement, correctness) out of 100.

Diff view and tappable highlights

Toggle a word-level diff that color-codes every addition and removal between your original and corrected text, or tap any highlighted phrase in the result to jump straight to its error card.

Built-in AI writing coach

Open a chat that already knows your full check, original text, corrections, every error, and your stats, and ask why a fix was made. It teaches the underlying grammar rule, even acknowledging debatable calls like the Oxford comma.

Version history with smart rechecks

Keep up to 10 versions per check and flip between them with previous/next navigation. Refine with one-tap chips (be stricter, more lenient, style only, grammar only) or your own custom instructions.

Voice and photo input

Dictate your text with built-in voice recording (transcribed by Whisper) or attach up to 5 photos for extra context, straight from camera or gallery.

Listen to your corrected text

Tap Listen to hear the polished version read aloud with natural AI text-to-speech, a quick final proofread for your ears.

Export, save, and search history

Copy to clipboard, share, or export as Markdown or a formatted PDF. Every check is saved to a searchable cloud history with today/week/month filters, bookmarks, and version counts.

How it works

From idea to done in seconds.

  1. 01

    Paste, type, or dictate your text, attach optional photos for context, then pick a fix mode and writing style and tap Check Grammar.

  2. 02

    The AI asks 3-4 quick clarifying questions (skippable) before streaming the corrected text live alongside readability stats and a quality score.

  3. 03

    You then review each error card, fixing or skipping changes one by one, open the coach chat to ask why a rule applies, or recheck with refinement instructions to spawn new versions.

  4. 04

    Finish by copying, sharing, exporting to PDF, or bookmarking the check to your searchable history.
