ai-text-watermark

Invisible, key-verifiable watermarks for AI / LLM text — SynthID-Text style, in Rust + WebAssembly. Generate, detect, embed a secret provenance message, and run an ultra-low-latency decode-loop proxy — Node and browser.

This is a thin standalone wrapper that re-exports @claude-flow/watermark verbatim, so you get a memorable install name without any code duplication.

npm install ai-text-watermark

const { Watermarker, StreamProxy, detect } = require('ai-text-watermark');

const wm = new Watermarker({ key: 'my-secret', scheme: 'gumbel' });
const out = candidatesPerStep.map((c, i) => c[wm.step(c, probs[i])]);
detect(out, { key: 'my-secret', scheme: 'gumbel' }).isWatermarked(1e-6); // true

Browser / bundlers: import { init, Watermarker, detect } from 'ai-text-watermark/web'; await init();
