environmental impact
We get it — AI uses real energy and real water. But the problem isn't using AI, it's using it inefficiently. Uploading a messy PDF means the AI has to work harder, retry more, and consume more resources to get you a useful answer. Slidedown makes every prompt count.
A note on honesty:AI energy use is real, but often overstated online. The bigger win is using AI intentionally — fewer, better prompts rather than dozens of frustrated retries. That's what Slidedown helps you do.
why it works
AI tools have a limit on how much text they can read at once. PDFs are full of hidden junk — layout code, image data, metadata — that eats into that limit fast. Slidedown strips all that away so the AI reads your actual content, not the noise.
raw PDF — hits the AI limit fast, often cuts off mid-lecture
after slidedown — same content, a fraction of the space used
your whole lecture fits without upgrading your AI plan
