Free AI Text Summarizer
Summarize any text into organized topics and subtopics.
A text summarizer for clear topic structure
The text summarizer is intended for plain text that does not fit a specialized format. It finds the central subject, separates related topics and places supporting information underneath them, turning dense paragraphs into an editable hierarchy.
Unlike the article mode, it does not assume that the source contains a thesis or formal conclusion. That makes it suitable for instructions, transcripts, explanations, copied document sections and other multi-paragraph text where the main challenge is seeing the structure.
Text that benefits from a structured summary
Instructions and procedures
Group prerequisites, steps, warnings and expected outcomes into a more navigable overview.
Interview transcripts
Organize recurring subjects, notable responses and follow-up points without treating every sentence equally.
Copied document sections
Reduce selected chapters or passages to the information needed for review, planning or discussion.
How summarized text is organized
The output favors topic hierarchy over sentence order. Related ideas that appear in different parts of the source may be grouped under one branch, while distinct subjects become separate branches.
You can then edit labels, split an overloaded branch, merge repeated points or add context. This is especially useful when the original text contains good information but lacks visible headings.
- A short label for the overall subject
- Topic branches created from recurring or important ideas
- Definitions, facts and details grouped by relevance
- A reusable map for review, explanation or planning
How it works
Find the important information without reading the same text repeatedly.

Source-grounded
The generated structure is checked against the supplied text.
Editable result
Continue refining the summary in the mind map editor.
Prepare text for better summarization
Use meaningful boundaries
Submit a complete topic, section or conversation rather than cutting the text in the middle of an explanation.
Preserve useful headings
Existing headings provide strong clues about structure and should remain unless they are unrelated page furniture.
Remove repeated boilerplate
Delete email signatures, navigation text, disclaimers or duplicated headers when they do not contribute to the subject.
Split unrelated subjects
If one input contains several independent topics, summarize them separately to avoid a shallow or confusing hierarchy.
Text length and interpretation limits
Each submission is limited to 40,000 characters. Very dense text can still produce a large map, and shortening the source does not guarantee that every detail will be retained.
The tool summarizes meaning from the supplied text; it does not proofread, translate, verify facts or infer missing context reliably. Review technical terminology, numbers and ambiguous references before using the output.
Frequently asked questions
How much text can I summarize?
You can submit up to 40,000 characters at a time.
What does the result look like?
The result is an editable mind map with topics, subtopics and source-backed details.
Can I edit the summary?
Yes. After generation, you can continue editing and exporting the mind map.
What is the difference between Text Summarizer and Article Summarizer?
Text Summarizer works with general multi-paragraph text and organizes it by topic. Article Summarizer is tuned to look for an article's thesis, arguments, evidence and conclusion.
Can I summarize a transcript or conversation?
Yes. Pasted transcripts can be grouped by recurring topic and notable point. Keep speaker names when attribution matters, and verify the map before quoting anyone.
Does the text need headings?
No. Headings can improve the structure, but the tool can identify themes in ordinary paragraphs. You can add or rename branches after generation if the source structure is unclear.
Will every sentence appear in the mind map?
No. A summary intentionally prioritizes important and recurring information. If a small detail is essential to your task, confirm that it appears or add it manually in the editor.
