Free AI Summarizer in the Format You Need
Paste an article, notes or a report and choose what comes back: five bullet points, one clean paragraph, a one-line TL;DR, the key quotes, or a list of action items. With a free account you can attach a PDF instead.
Summary Formats
A summary is only useful in the shape you will use it. Tell the summarizer which one you want, or ask for two at once.
Five to ten short points, one idea each, in the order the text makes them. Good for study notes, research and anything you will skim again later.
A connected summary in full sentences, with the argument and how it gets there. Good for a report introduction, an abstract or explaining a text to someone else.
One or two sentences with the main point and nothing else. Good for a long email thread, a news story or deciding whether a text is worth reading in full.
The sentences that carry the argument, copied word for word, each with a line on why it matters. Good for essays and articles where you need to quote the source.
What needs to happen, who does it and by when, pulled out of meeting notes, a brief or a long message. Good for turning talk into a to-do list.
A table of pros and cons, a summary for a 10-year-old, one line per section, a summary in another language. Describe it and the AI builds it.
How to Summarize with AI
Paste or attach, pick a format, check the result.
Tap one of the formats above the box. The instruction goes in and waits for your text.
Paste it after the instruction. With a free account, use the paperclip to attach a PDF or a text file instead.
The summary arrives in seconds for a short text and a little longer for a long one.
Compare the summary with the source for anything important it left out, then ask for another format or a shorter version in the same chat.
For a better summary
- • Say what the summary is for: an exam, a meeting, a decision.
- • Ask it to keep numbers, names and dates exactly.
- • Ask what the text does not say, as well as what it does.
- • Turn on web search if you want it to add background from the web.
How Long Can the Text Be?
Pasting works for anything from a paragraph to a long article or a set of meeting notes, and it needs no account. For a very long text, such as a book chapter or a report of many pages, split it into sections and summarize each one, then ask the chat to combine the section summaries into one. That keeps each summary detailed and makes it easy to see where every point came from.
To summarize a file, create a free account and attach it with the paperclip. You can add up to 5 files per message: PDFs up to 20 MB each and text files such as txt, md, csv or json. Word files are not supported, so save a docx as a PDF first. PDFs are read by the Claude and Grok models, not by the GPT models, so pick Claude Haiku 4.5 or Grok 4.5 before you send.
You can also ask for more than one format from the same text. A common pair is a TL;DR on top and bullet points below it; for meeting notes, a one-paragraph summary followed by action items. Ask once, and the answer comes back in that order. If the text has sections, ask for one line per section, which keeps the structure of the original and shows you where to read in full.
A PDF that is a scan of paper pages, or mostly images, may read less reliably than a PDF with real text in it. If the summary misses parts, paste the text of those pages directly.
Models That Summarize
All of them can summarize pasted text. For a PDF, choose a Claude or Grok model.
The default in the chat. Fast, reads PDFs, good for everyday summaries.
Quick summaries of pasted text. Reads images, not PDFs.
Direct, compact summaries. Reads PDFs.
For long or dense documents. A little energy per message, reads PDFs.
For careful reading of complex material. More energy per message.
A new account gets energy to start and can claim more every day.
How fast does it summarize?
We sent one 300-word article, pasted into the chat with a request for five bullets and a TL;DR, to each free model on 9 October 2026. Grok 4.5 finished first, in 7 s.
| Model | First words after | Full answer after | Answer length |
|---|---|---|---|
| 01Claude Haiku 4.5 | 10 s | 14 s | 218 words |
| 02GPT-5.6 Luna | 8 s | 9 s | 115 words |
| 03Grok 4.5 | 3 s | 7 s | 178 words |
Summarizer FAQ
What people ask before they summarize a text with AI.
Yes, to start. Claude Haiku 4.5, GPT-5.6 Luna and Grok 4.5 summarize pasted text for free, with a daily limit for guests. Attaching files needs a free account.
Yes, with a free account. Attach a PDF up to 20 MB with the paperclip and pick a Claude or Grok model, since the GPT models do not read PDFs.
Not directly: docx files cannot be attached. Save the document as a PDF, or copy the text and paste it into the chat.
Paste the text of the page into the chat for the most reliable result. Videos cannot be uploaded to the chat; if you have a transcript, paste that.
A summary keeps only the main points and is much shorter than the original. A paraphrase keeps roughly the same detail and length, in different words. Both need the source cited if you use them in your own work.
Yes, with an account: attach up to 5 files in one message and ask for one summary of each, or one summary that compares them.
Usually good, never guaranteed. AI can miss a point or state something the text does not say. For anything important, check the summary against the source.
Yes. Ask for it: "summarize this in Spanish" works for text in any language the model reads.
