What's new

New in ToneSwap: April 2026

A roundup of everything we shipped this month. Student tools, a new Summarizer, auto-built voice profiles, and more.

For students

Essay Rewriter

A dedicated page for rewriting essay paragraphs in academic English. Five student-shaped tones: Essay paragraph, Research paper, Discussion post, Email to professor, and Thesis section. Each is tuned for a specific academic context.

Length controls

Choose Shorter, Same, or Longer before you rewrite. ToneSwap adjusts the output to a specific word-count target. Useful when you are writing to a word count or need to trim a paragraph without losing substance.

Freeze words

Wrap any word or phrase in [square brackets] and it stays exactly the same in the rewrite. Citations like [Smith, 2024] and technical terms like [Constructivism] survive intact. No more fixing mangled references after every rewrite.

Readability stats

Every rewrite now shows word count, sentence count, reading level (Easy to read, Standard, Complex, Very complex), and estimated reading time. No voice profile needed. Shows on every single rewrite.

New tools

Summarizer

Paste a long text and get the key points extracted. Not a rewrite, a real summary: overview sentence plus bullet points for each claim. Works on journal articles, textbook paragraphs, research papers, long emails. Preserves names, dates, and citations.

Voice matching

Auto-built voice profiles

ToneSwap now learns your voice automatically from your normal rewrites. After a few uses, it builds a voice profile in the background. Your next rewrite sounds more like you, with a voice match score showing how close it got. No setup page, no onboarding modal, no extra steps.

Voice score breakdown

Click the ? next to your voice match score to see a 4-category breakdown: Sentence rhythm, Vocabulary, Tone and formality, Structure. Each gets its own 0-100 score so you can see exactly where the rewrite matches your voice and where it diverges.

Chrome extension

Updated to the new design

The Chrome extension now matches the website: pure black background, Instrument Serif logo, gold accent. Same tones, same voice matching, same quality. Rewrite text on any page without leaving it.
