How long can the text be?

There's no hard limit — text above a configurable character threshold is automatically split into overlapping chunks, summarised, then merged into one final summary so context isn't lost at the seams.

What's the difference between abstractive and extractive?

Extractive picks and lightly trims existing sentences; abstractive rewrites the ideas in new, shorter sentences. Abstractive usually reads better; extractive stays closer to the source wording.

Can I get a summary focused on one topic?

Yes — set focus keywords or a specific question and the summary is instructed to prioritise passages relevant to that, ignoring unrelated tangents.

Are the word/sentence stats accurate without AI?

Yes, the local statistics panel is computed directly in your browser from the raw text and doesn't depend on the AI call at all.

Is my document uploaded anywhere?

No — it's only sent as a prompt to the AI provider you're using (your own key, or the site's stateless shared key), never stored in a database.

About ai summarizer

AI Summarizer condenses long text into exactly the shape you need: a paragraph, bullet list, numbered list, one-line TL;DR, executive summary, key takeaways, action items, study notes, an abstract or meeting minutes.

Control the target length by percentage, word count or bullet count, choose abstractive or extractive style, focus on specific keywords or a question, and keep quotes, numbers and names intact. Long documents are automatically chunked with overlap and merged into one coherent summary.

Local statistics — words, sentences, reading time and compression ratio — are computed instantly in your browser, no AI call needed for those numbers.
