See the key ideas of a paper as a simple flowchart, built by transparent rules.
What this tool does
This tool turns a dense abstract or introduction into a simple flowchart of its key sentences. It picks sentences that define, explain, or link concepts, using fixed rules such as looking for phrases like “is defined as” or “leads to”, and then stacks them in reading order with arrows between them. The result is a quick visual skeleton of the argument that you can scan before reading the full text closely.
It works fully in your browser. Nothing is uploaded to a server, and you do not need an account. Paste your text, press the button, and read the result on the same page. That makes it useful for students, researchers, and anyone who has to get through a long paper quickly without losing the important parts.
How to use it
Paste an abstract, an introduction, or a single dense section into the box and press the map button. Read the flowchart from top to bottom, and check each box against the original text. If a box looks wrong or out of place, remember the tool only matched words, it did not understand the idea, so trust the original sentence over the flowchart.
Worked example
Consider an abstract about motivation: “Motivation is defined as the drive to act toward a goal. Intrinsic motivation involves personal interest, while extrinsic motivation depends on external rewards. This distinction leads to different predictions about persistence.” The tool picks all three sentences, because they contain definition and linking phrases, and stacks them as three boxes with arrows. In one glance you see the definition, the two types, and the consequence, which is the whole skeleton of the abstract.
How to read the results
The output is a vertical flowchart: one box per picked sentence, in the order they appear, with a count of sentences shown out of the total pasted. Sentences that define or connect ideas appear first in effect, because the rules favour them. If very few sentences are picked, paste a longer passage or accept the first five sentences as a fallback skeleton.
Do not treat the output as a final answer. It is a starting point for your own reading. Skim the highlighted parts first, then read the full passage around anything that matters for your work. A tool can point at the likely important sentences, but only you can judge whether they are actually important for your question.
Honest limits
This is a heuristic, not comprehension. It can pick a sentence that merely mentions a linking word, and it can miss the true main idea if that idea is phrased unusually. It does not rank importance the way a human would, and it cannot tell whether a link the author claims is actually supported. Use the flowchart to orient yourself, then read the real text.
This tool does not use artificial intelligence, and it does not understand your paper the way a human reader does. It follows fixed rules that you can inspect in the results. That is a strength when you want transparent, repeatable results, and a weakness when a passage needs real understanding, context, or judgement.
Tips for best results
Paste clean text. Remove page headers, footers, and reference lists before you paste, because they add noise to word counts and sentence scores. Work on one section at a time for long papers, and keep your original file open beside the tool so you can check anything surprising against the source. If you use the result in your own writing, always cite the original paper, never the tool output.
Frequently asked questions
Is it free? Yes. The tool is free to use online, with no sign-up and no download.
Is my text stored anywhere? No. Everything runs in your browser tab. Closing the tab removes your pasted text.
Can I trust the output completely? No tool of this kind should be trusted blindly. Use it to speed up reading and checking, then verify the important claims yourself in the original text.
