A private text summarizer that works the way you read

Summarize It shortens long writing into something you can take in at a glance, right inside your browser. It is built for the everyday jobs a good summarizer should handle: skimming a long article before you commit to reading it, pulling the decisions out of a meeting transcript, turning a wall-of-text email thread into three lines, or condensing research notes into key points. Because the work happens on your device, the text you paste is never uploaded, there is no account to create, and there is no per-character cost — summarize as much as you like.

Two engines, one simple tool

The Instant engine is an extractive summarizer: it analyses your text, scores every sentence by how much of the document's meaning it carries, and keeps the strongest ones in their original order. It needs no download, runs in a fraction of a second, and handles text of any length — paste a whole report and it still works. The optional AI engine downloads a small summarization model once and then rewrites the gist in fresh wording for a smoother read; it runs entirely on your device and automatically splits very long input into chunks so nothing gets cut off.

Control the shape and length

Pick the output that fits the moment. Paragraph gives you cohesive prose, Bullet points break the summary into one line per key idea, and Key points distil the few most important takeaways into a tight TL;DR list. A Short / Medium / Long control sets how much detail to keep, scaling with the size of your text. Turn on key-sentence highlighting to see exactly which lines in your source the summary was drawn from — useful when you want to jump back to the original for context.

Built for getting work done

When you need to keep or share a summary, Pro exports it as Markdown, plain text, JSON or a clean PDF. The batch digest takes a stack of documents — separate them with a line of dashes — and returns a summary of each plus one overall digest, which is ideal for a reading list or a week of notes. Focus keywords let you steer the summary toward specific topics, the saved library keeps the summaries you revisit, and PDF import opens documents straight into the tool. Everything still runs on your device — a genuinely private alternative to cloud summarizers that meter words or require an account.

Frequently asked questions

Is the summarizer really free and private?
Yes — summaries are generated in your browser, so the text you paste is never uploaded. No signup, no per-use cost.
What's the difference between the Instant and AI engines?
Instant is an extractive summarizer in plain JavaScript — it keeps your most important sentences, needs no download, and works on any length. The AI engine downloads a small model once and rewrites the gist in fresh wording, all on your device.
Can I get bullet points or key takeaways?
Yes. Choose Paragraph for prose, Bullet points for one line per key sentence, or Key points for a short TL;DR list.
How do I control the length?
Pick Short, Medium or Long. Length scales with your text, so a long report produces a proportionate summary rather than one line.
Can it handle a very long document?
The Instant engine handles any length directly. The AI engine auto-splits long text into chunks, summarizes each and combines them.
What does Pro add?
An export suite (Markdown/TXT/JSON/PDF), a batch digest for many documents at once, a saved-summary library, focus keywords, and PDF import — all still on your device.
Note: Summaries are generated automatically and may omit nuance or context — check the source before relying on them for important decisions. The AI engine downloads a model from a CDN on first use and then caches it for offline use; all processing happens in this browser and nothing you paste is uploaded.
