See which tradition each sentence of a theory text belongs to.
What this tool does
This tool sorts the sentences of a theory text into schools of thought using keyword buckets. Built-in buckets cover behaviourism, cognitivism, constructivism, and psychoanalysis, and you can add your own school with your own keywords in the second box. Each sentence is assigned to the bucket with the most keyword matches, and the tool reports counts per school alongside the labelled sentences.
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 a theory passage into the first box, and optionally add custom schools in the second box using the format school name, colon, comma-separated keywords. Press the categorize button and read the counts first, then the labelled sentences. A sentence with no matching keywords is left unclassified rather than forced into a bucket.
Worked example
From two sentences, one about behaviour shaped through reinforcement and stimulus response, and one about memory and schema processing, the tool labels the first as behaviourism and the second as cognitivism, with one sentence each. That split tells you the passage mixes traditions, which matters when you describe what a theory actually claims.
How to read the results
The output has a counts table per school and a full list of sentences with their assigned school in brackets. Custom buckets appear in the table alongside built-in ones, so your own categories are treated exactly like the built-ins. Unclassified sentences are listed too, so nothing is silently hidden.
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
Keyword buckets are a blunt instrument. A sentence can use a word from one tradition while arguing against it, and many sentences genuinely blend traditions. The tool counts word matches, it does not understand positions, and it cannot resolve borderline cases. Use the labels as a first sorting pass, then judge the tricky sentences yourself.
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.
