The first visit downloads about 13 MB. After that it opens from your browser's cache.Handwriting reading uses Claude, so it needs your own Anthropic API key. Get one at console.anthropic.com (API keys), then paste it here. It's saved only on this computer, and each answer read costs a fraction of a cent.
On the website, the key stays in this browser and goes only to Anthropic. Use it on a computer you trust, since browser extensions you install can read what websites store.
