WriteGooderer proofreading a paragraph with a Gooderness score and inline diff

Works in Gmail, Slack, Notion, GitHub, LinkedIn, and the rest of the textareas you live in.

Why this exists

Chrome bundled a 4GB AI model. We gave it a job.

Out of the box, Chrome's on-device Gemini Nano mostly powers Help me write inside the omnibox. For most of us, that's a 4GB roommate sitting around doing nothing. WriteGooderer points the same model at every other text field on the web, so the AI already on your disk has actual work to do.

Privacy

Private by default

Every keystroke stays on-device. No accounts, no servers, no telemetry. Just Chrome's built-in Gemini Nano, doing the work locally.

Review

Edit before you commit

A side-by-side diff shows every fix before it touches your draft. Apply the whole rewrite, or only the changes you actually want.

Tone

Sound how you want

Switch between Professional, Friendly, LinkedIn Influencer, and Passive Aggressive in one click. Same point, different voice.

How it works

Three clicks, zero context-switching.

  1. 1

    Click into any text field on the page. A small floating W appears beside it.

  2. 2

    Open the card to proofread, check your Gooderness score, or pick a tone.

  3. 3

    Skim the diff, then send the edits straight back into your draft.

Install

Up and running in under a minute.

  1. Clone the repo: git clone https://github.com/victorhuangwq/WriteGooderer.git
  2. Open chrome://extensions and turn on Developer mode.
  3. Click Load unpacked and select the dist/ folder.

If the popup says the Prompt API is unavailable, check the requirements for the flag and on-device model setup.

Open source

If it earned its keep, star it.

WriteGooderer is free, MIT-licensed, and built in the open by one person in spare hours. A star takes a second, helps other writers find the project, and is the clearest signal to keep shipping updates.
