How does this text summarizer work?

It is an extractive summarizer: it picks the most important sentences from your text and doesn't write new ones. Each sentence is scored with TextRank, which links sentences that share words and ranks the ones most connected to the rest of the text. That score is blended with the sentence's position (opening sentences of paragraphs get a small boost), how many of the text's top keywords it contains, and its overlap with the title.

No. It uses a published ranking algorithm and simple statistics, and it runs entirely in your browser. Because it only selects sentences, the summary never contains facts or claims that aren't in your text.

Why does the summary sometimes read a little choppy?

Sentences are taken out of their context, so a picked sentence may start with "This" or "However" and refer to something that was left out. Keep the original order on, add a sentence or two, or edit the result lightly before you share it.

What do focus keywords do?

Sentences that contain your focus keywords get a strong extra score, so the summary leans towards that topic. Separate several keywords with commas. Matching ignores simple endings, so "automate" also matches "automated" and "automates".

How long can the text be?

Long reports and transcripts of 100,000 words or more work. The ranking uses an index of shared words rather than comparing every pair of sentences, so it stays fast. Uploads are limited to 10 MB of plain text or Markdown.

Which languages work?

It works best in English, because the stop word list and word endings are English. Other languages that separate words with spaces and sentences with full stops still get a usable result.

Why fast replies win more Instagram sales

Most Instagram sales start in the DMs. A follower sees a post, comments a keyword like "PRICE" and waits for an answer. The speed of that first reply decides a lot.

Studies of sales leads have shown the same pattern for years. Leads contacted within five minutes are far more likely to buy than leads contacted an hour later. Instagram buyers behave the same way. They scroll on, see a competitor and forget about you.

Replying fast by hand is hard. Comments arrive at night, on weekends and during busy launches. A small team can't watch every post all day. One skincare founder told us her team missed about 40% of comments during a launch week.

Automation solves the speed problem. A comment-to-DM tool replies to every keyword comment in seconds, sends the link or price, and can ask for an email address. Your team then picks up only the conversations that need a person.

The result is simple. Faster replies mean more conversations, and more conversations mean more sales. Start with your most popular post and automate the first reply there.

An extractive summarizer, explained

There are two kinds of summarizers. Abstractive ones write new sentences, which is what AI chat tools do. Extractive ones, like this tool, choose the most important sentences from the original and leave them word for word. The result is less smooth, but every sentence is something the author really wrote, so nothing is invented or misquoted.

How sentences are ranked

The text is split into sentences. Abbreviations such as "Dr." and "e.g.", decimals and quotes don't break a sentence, and headings are recognised and used as the title.
Each sentence becomes a set of meaningful words: common words such as "the" are removed and simple endings are trimmed.
TextRank links every pair of sentences that share words and runs a PageRank-style calculation (damping factor 0.85). Sentences that share ideas with many others rank highest.
The final score blends TextRank (55%) with keyword weight (20%), position in the text (15%) and overlap with the title (10%), plus a boost for your focus keywords.
The top sentences are picked, skipping near-repeats, and shown in their original order unless you turn that off.

Getting a better summary

Well-structured text with clear paragraphs summarises best. Transcripts with very long run-on sentences are harder.
For a short email, 2 or 3 sentences is usually enough. For a long report, 10-20% gives a readable overview.
Check pronouns: a picked sentence starting with "It" or "This" may need the subject spelled out.
