AI Summarizer

What the summarizer is good for

Long texts pile up: a report you were asked to read before a meeting, a forty-message email thread, a lecture transcript, a policy document with the important part buried on page six. The summarizer reads the whole thing and gives you the core in the shape you choose, so you can decide whether the full text needs your attention.

It runs on Grok 4.20. The model can take in far more text than this page's input box allows, so the limit you notice is the character counter under the box, not the model. Its instructions are strict: keep the facts, numbers, names and decisions; leave out repetition and side remarks; never add information that is not in the source and never give an opinion of its own.

How to use it

1. Paste the text into the box. If the counter turns red, split the text into parts and summarize each one.
2. Pick a shape. Key points gives a bulleted list. Short paragraph gives flowing prose. TL;DR + details puts the gist in one bold line with bullets underneath. Section outline follows the structure of the original. Decisions and tasks pulls out who agreed to what and by when. Questions and answers turns the text into four to six questions a reader would ask, each answered from the text.
3. Choose the depth: very brief (the three most important things), normal (about five points) or in depth (every section with its supporting details).
4. Generate, then copy, regenerate with a different shape, or press Continue in chat to ask follow-up questions about the text.

Tips for sharper summaries

• Remove the noise first. Navigation menus, cookie notices and signatures pasted along with an article only distract the model.
• Use Decisions and tasks for meetings. It is the fastest way to turn rough notes into a list you can send to everyone who was there.
• Try Questions and answers for studying. It shows what a text actually answers, which is a good test of whether you understood it.
• Ask follow-ups in the chat. "Which of these points does the author support with data?" is a useful second question.

Example

We pasted a short Russian news item about a city council plan to close a central street to cars at weekends, with the shape set to Decisions and tasks. Grok 4.20 answered in Russian, as it should. In English, the result read:

Nothing was added, and the one hard number in the source, the ten percent threshold, survived.

Limits to keep in mind

• A summary is a lens, not the source. Before you quote a figure or act on a decision, find it in the original text.
• Nuance gets compressed. Hedges such as "early results suggest" can come out sounding more certain. Very brief summaries lose the most.
• Text only. This tool cannot open links, PDFs or videos. Copy the text itself, or a transcript of the video. To work from a screenshot of a page, attach it as an image in the chat instead.
• Confidential material. The text is sent through our server and AI gateway to the model provider. Think twice before pasting internal documents your employer would not want shared.

Frequently asked questions

How long can the text be?

As long as the counter under the box allows. For a book chapter or a long report, summarize it section by section and then ask the chat to combine the partial summaries.

Can it summarize a web page from a link?

No. Grok on our site has no internet access, so it cannot open a URL. Copy the article text from the page and paste it in.

Does it work in other languages?

Yes. Paste a Spanish report and you get a Spanish summary; the tool always answers in the language of the source. To get it in another language, summarize first and then run the result through the AI Translator.

Is it free?

Yes. A summary costs one message from the free daily allowance of 30, the same pool the chat uses.

Can I trust it for research?

As a first pass, yes; as a final source, no. Our guide on how to fact-check AI answers shows quick ways to verify, and this chat prompt helps: summarize and flag claims to check.
