Is my text sent to a server?

No. The summarizer runs entirely in your browser with a self-hosted AI model. Your text never leaves your device, and after the one-time model download nothing is sent over the network.

Why is the first summary slow?

The first run downloads a ~75MB model once and caches it in your browser. It also uses your device's CPU (or GPU via WebGPU when available), so longer text takes longer. Subsequent runs skip the download.

How good are the summaries?

This uses a small, efficient model chosen so it can run in a browser without uploading your data. It's great for getting the gist, but it's not as polished as a large cloud model — always read the result before relying on it.

Is there a length limit on the input?

The model reads a limited amount of text at once, so very long inputs are trimmed. For long documents, summarize a few paragraphs at a time and combine the results.

Does it need a fast computer?

It works on most modern devices. Browsers with WebGPU run it noticeably faster; otherwise it falls back to a single-threaded WASM engine that still works, just more slowly.

AI Text Summarizer

Summarize long text into a short version on-device — paste an article or notes and get the gist, with nothing uploaded.

Runs entirely on your device— nothing is uploaded, so processing uses your own CPU and memory. Large files can take a while (don't worry, it hasn't frozen), and very large files may be slow or crash the tab on phones — for big files, use a desktop or laptop.First run downloads about 77MB — the model is cached after that, so later runs start instantly. Best on Wi-Fi.

Paste a news story or blog post and get the key points in a few sentences instead of reading the whole thing.

How to use the Text Summarizer

Paste the text you want shortened — an article, meeting notes, documentation, an email thread — into the box. Nothing is uploaded; the summary is generated on your own device.

The first time you use it, a small AI model (~75MB) downloads once and is cached in your browser. After that it runs instantly, even offline.

Pick a summary length — Short, Medium or Long — then click "Summarize".

Read the summary, tweak the length if you want a shorter or fuller version, and use Copy to grab the result.

For best results keep the input to a few paragraphs at a time — very long text is trimmed to what the model can read at once, so summarize in sections if needed.
