Changelog

Every update that reached NeuralWriter, from the first paraphraser in 2022 to today: new tools, improvements and fixes. Newest first.

2026

Lock words the paraphraser must not change

Some words have to survive a rewrite untouched: a brand, a product name, a legal term, a quote. Now you can tell the paraphraser which ones.

  • New Don't change field under the text: type a word or phrase and press Enter, up to 20 per text
  • Suggestions from your own text (acronyms, brand names like iPhone, quoted phrases, names in the middle of a sentence), added with one click
  • Locked phrases keep their exact spelling, capitalization and form. The sentence is rebuilt around them, so it stays grammatical even in languages with cases and genders
  • If a locked phrase still goes missing in the result, the text is rewritten again before you see it
  • Formatting survives the rewrite: Markdown headings, bold text, lists and tables, HTML tags, links, inline code and citations such as (Smith, 2020) or [1] come back exactly where they were
  • Texts sent to the writing tools are deleted automatically within 24 hours. The Privacy Policy now says so explicitly

Paraphraser: 8 writing styles and plain-language standards

Until now you could only choose how hard the paraphraser rewrites. Now you also choose what the text should sound like, and who it is for.

  • 8 styles: Standard, Fluent, Formal, Academic, Simple, Creative, Shorten (30–50% fewer words) and Expand (30–60% longer)
  • 12 language standards for writing that has to follow a rule, not a taste: ISO 24495-1 plain language, Easy-to-Read (ISO/IEC 23859), CEFR A2–B1, the CDC Clear Communication Index, ASD-STE100 Simplified Technical English, Attempto Controlled English, UX writing, Amazon-style narrative, and four English word lists (Oxford 3000, Ogden's Basic English, Globish and the Academic Word List)
  • National standards appear when your text is in their language: Leichte Sprache and Einfache Sprache for German, Lectura Fácil, FALC, Klarspråk, Selkokieli, やさしい日本語 and others, 17 in total
  • Strength stays a separate choice: Light keeps your sentence order and voice, Hard rewrites thoroughly
  • Rephrase again gives you another version of the same text in one click
  • Check with AI detector opens the AI Detector with your result and starts the check right away
  • A guide on the page explains every style and standard and links to the official documents

NeuralWriter 2.0

We rebuilt neuralwriter.com from scratch. Every tool kept its address, so your bookmarks and links still work.

  • New design with a sidebar that groups the tools into Write & Rewrite, Analyze, Images, Video, Convert and Developers. Each tool has its own color
  • Light and dark theme, or follow your system setting
  • Faster pages: fonts and images are cached for a year, and nothing in the background starts before the page has finished loading
  • All 30 languages translated in full, including the guides and FAQs on every tool page
  • Every tool page has a quick-facts table, a guide and an FAQ

Eight new tools

  • Grammar Checker fixes grammar, spelling and punctuation and highlights every correction
  • Email Writer turns a short brief into a complete email with a subject line, greeting and sign-off, in any tone
  • Business Name Generator gives you 10 short, brandable names from a plain description of your idea
  • Background Remover cuts out the subject, including hair, and returns a transparent PNG
  • Change Background swaps the backdrop for a solid color, a soft blur, your own image or an AI scene described in words
  • Image Resizer sets an exact size or a ratio such as 1:1, 16:9 or 9:16 and exports PNG, JPG or WEBP
  • Video to MP4 converts MOV, WEBM, AVI and MKV into MP4 with the resolution and quality you choose
  • Page to PDF saves any web page as a PDF in A4, Letter or Legal, portrait or landscape
  • Files up to 7 MB, no sign-up and no watermark
  • Video Background Remover is in preview and marked "soon"

AI Detector: six engines, sentence by sentence

  • Every text is checked by six detectors at once: QuillBot, ZeroGPT, Originality.ai, Copyleaks, Grammarly and Ahrefs
  • Sentence highlights show which parts were flagged as AI, using the per-sentence data from Originality.ai, QuillBot and Grammarly
  • Each result appears as soon as its engine finishes, so one slow detector doesn't hold back the rest
  • When an engine doesn't support the language of your text (Originality.ai reads English only), its card says so instead of showing a score it can't stand behind

Image tools and long texts

  • Image Upscaler has two modes: Instant enlarges the image right in your browser, so the file never leaves your device, and AI redraws the details before scaling to the size you pick
  • Image Generator shows each result in a large preview, ready to download
  • Long texts no longer time out. A text task now runs in the background while the page checks on it, for up to four minutes
  • If our main AI engine is slow or unavailable, a backup engine finishes the job, so you get a result instead of an error

AI Detector: Grammarly added, all engines run in parallel

  • Grammarly's AI detector replaces Winston AI
  • All engines now start at the same time, and each result shows up the moment it is ready
  • Clearer messages when an engine doesn't support your language
  • Long texts get more time before a check gives up

New AI Detector with five engines

The AI Detector no longer relies on a single model. It now asks five well-known detectors and shows you each answer.

  • Checks with QuillBot, ZeroGPT, Originality.ai, Copyleaks and Winston AI
  • A score per engine, labeled Human, Mixed or AI
  • Progress steps while the engines work, so you know the check is still running

Image Generator: 25 styles and a prompt helper

  • Style picker with 25 looks, each with a preview: cinematic, anime, watercolor, oil painting, 8-bit and 16-bit pixel art, 3D render, comic book, low poly, polaroid, sketch, synthwave and more
  • Improve prompt turns a few words into a detailed description the generator understands better
  • A new generation model with sharper, more accurate images

2025

New Chrome extension

  • A short note under each tool's main button: starting a tool means you agree to the Terms of Service

A 404 page that helps

  • Mistyped or outdated links now land on a page that points you to the tools, instead of a bare error

Word Counter, rebuilt

  • Text metrics next to the counts: Text Nausea, lexical diversity, average sentence length and Flesch Reading Ease, each with a plain explanation of what a good value looks like
  • Keyword selection: pick a word and see where it repeats in your text
  • Pasted text loses its formatting, so counts aren't thrown off by hidden markup
  • Better language detection for Cyrillic texts
  • The cursor no longer jumps while you type

Image Generator: sizes and history

2024

Fair-use limits keep the tools free

The tools are free, and a handful of automated scripts were using up capacity meant for people.

  • Each tool has a per-minute limit that a person typing won't notice, with a clear message if you reach it
  • Image generation has a daily limit. Installing the NeuralWriter extension raises it

Image prompts in any language
