Why I Built This Summary Tool
Look, we've all been there. You've got a massive article sitting in front of you, maybe 5,000 words about something important, and you just need the key points. I got tired of highlighting paragraphs and taking notes manually, so I created this tool to do the heavy lifting.
What started as a simple text shortener turned into something bigger. I realized that just condensing words wasn't enough. People remember things better when they can see pictures alongside the text. And some folks prefer listening to information rather than reading it. That's why this tool gives you all three options at once.
Here's What Actually Happens When You Use It
Paste your long document into that text box. Could be anything - a news article, a chapter from a textbook, even meeting notes. Hit the generate button and watch what happens next.
The system chops your text into separate paragraphs and figures out what each one is talking about. If you've pasted something about factories and the Industrial Revolution, you'll see drawings of factory buildings and smokestacks. Writing about cities? You get skyline illustrations. It's not perfect, but it does a decent job matching images to topics.
Picking Your Preferences
There's a dropdown menu where you can choose between simple or detailed images. Simple mode draws basic shapes and gets straight to the point. Detailed mode adds more elements to make things look fuller. Honestly, I usually stick with simple because it loads faster, but detailed looks nicer for presentations.
You can also pick which voice reads your summary. Your computer probably has a bunch of different voices installed - some male, some female, different accents. Just pick whichever one doesn't annoy you after hearing it a few times.
Who Actually Needs This Thing
Students cramming for exams keep telling me this saves them hours. Instead of re-reading entire textbook chapters, they paste sections and get quick summaries they can review before tests. One person told me they made summaries of all their lecture notes and watched the videos on their commute to campus.
I've also seen teachers use it to create review materials. They paste curriculum content and share the videos with students who need extra help outside class hours.
Business people like it too. Someone from a marketing agency mentioned they summarize competitor reports this way before strategy meetings. Takes them 5 minutes instead of an hour to prep.
The Psychology Part Nobody Talks About
There's actual research behind why this works better than just reading. When your brain gets information through multiple senses at the same time, it creates stronger memories. That's not some marketing fluff - scientists have measured it.
| How You Learn | How Much You Remember |
|---|---|
| Just reading | 10-20% |
| Just looking at pictures | 30-40% |
| Reading + pictures together | 60-70% |
| Reading + pictures + listening | 75-85% |
So yeah, combining all three methods isn't just convenient - it literally helps you remember stuff better. That's the whole reason I bothered adding the audio narration feature instead of leaving it as just text and images.
The Technical Stuff (Skip If You Don't Care)
How the Images Get Made
Everything happens right in your browser using something called HTML5 canvas. The tool doesn't download images from Google or pull from some database. It actually draws the illustrations fresh each time based on keywords it finds in your text. That's why the images always relate to what you wrote, even if the quality isn't gallery-worthy.
About That Voice Feature
Your web browser already has text-to-speech built in - most people just don't know it's there. This tool taps into that existing feature. Whatever voices your computer or phone has installed will show up in that dropdown menu. I set it to speak a bit slower than normal talking speed because people complained they couldn't keep up otherwise.
Downloading the Video File
When you click download, the tool records what's happening on screen and mixes it with the audio. Everything gets saved as a WebM video file. This all happens locally on your device - nothing gets uploaded to my servers or anyone else's. Your document stays completely private.
Tips From People Who Use This Daily
Works best when your text is already broken into clear paragraphs. If you paste one giant wall of text, the results get messy. Aim for somewhere between 3 and 7 paragraphs per session.
Each paragraph should cover one main idea. Don't mix five different topics into the same paragraph and then wonder why the illustration looks generic. Keep things focused and you'll get better visual matches.
One more thing - if you're summarizing academic papers, copy just the main content. Leave out the reference lists and footnotes. Those don't add anything useful to your summary and just clutter everything up.
Your Privacy Matters
I get asked about this constantly, so let me be clear: Nothing you paste into this tool goes anywhere. No uploads, no cloud storage, no data collection. Everything processes right there in your browser tab. Close the tab and it's gone forever. I built it this way on purpose because I wouldn't want my confidential work documents floating around on random servers either.
Does It Work on Your Device?
Should work fine on Chrome, Firefox, Safari, and Edge. Basically any modern browser from the last few years. Really old browsers might have trouble with the voice or video features, but the basic summarizing and images should still work.
Phones and tablets can run it, though recording videos on mobile browsers gets iffy depending on your device. The main features - making summaries and showing images - work perfectly fine on smartphones if you need to process something while you're out and about.
