How it works
- Pick the best engineThe page checks for the Writer and Rewriter APIs first, then the general Prompt API, and says which one it found.
- Generate or rewriteYour text and options go to the on-device model. Nothing is sent to a server.
- Check the resultEvery edit runs the local writing check, so you see the reading score change as you type.
// Draft new text
const writer = await Writer.create({ tone: "neutral", length: "short", format: "plain-text" });
const draft = await writer.write("An email moving the launch to Wednesday");
// Change the tone of existing text
const rewriter = await Rewriter.create({ tone: "more-formal", length: "as-is" });
const formal = await rewriter.rewrite(draft);
// No Writer or Rewriter? The general Prompt API can do both
const session = await LanguageModel.create();
const reply = await session.prompt("Rewrite this more formally: " + draft);
