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.
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.
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.
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.
