See the rhetoric behind the words.

Select text on any page, and Colorphrase colour-codes it: the techniques that try to persuade you, facts and opinions, the emotions it plays on. Hover a highlight to see why it was marked.

An opinion article in which Colorphrase has highlighted manipulation techniques — urgency, us vs them, fear-mongering, appeal to authority — with a legend counting each colour and a tooltip giving the reason for one highlight.

Palettes

Read a text through the lens you need

A palette is a set of colours, each with a description of what to mark. Five come with Colorphrase; make your own in a minute.

  • Manipulation techniques

    Fear-mongering, us vs them, urgency, appeals to authority, flattery, guilt-tripping, cherry-picking.

  • Fact vs opinion

    What can be checked, what is someone's view, what is a guess about the future.

  • Emotions

    Fear, anger, sadness, shame, hope: what each phrase is built to make you feel.

  • Your own

    "Praise", "Complaint" and "Specifics" for product reviews, or anything you need: a name and a description per colour.

How it works

Select, right-click, read

  1. Set up once. After installing, click "Download the model": Chrome fetches its built-in AI, Gemini Nano (about 4 GB), and keeps it on your computer.
  2. Select text on any page — a paragraph or a whole article — then right-click → Colorphrase → a palette, or press ⌘⇧Y (Ctrl+Shift+Y).
  3. Read it in colour. Links and layout stay as they were. Hover a highlight for its reason, click a colour in the legend to show only it, copy a report, or clear the page.

Needs desktop Chrome 138 or later, 22 GB of free disk space, and a graphics card with more than 4 GB of memory or 16 GB of RAM. Works best in English, Spanish, Japanese, German and French.

Privacy

Your text never leaves your computer

Colorphrase runs on Chrome's own built-in AI, on your computer. There is no server, no account, no API key and no analytics: the extension makes no network requests at all. It reads a page only when you ask it to. The privacy policy says exactly what it handles.
