Rankify
Any question-paper PDF becomes a real CBT in your browser
What it does
Rankify turns any question-paper PDF into a genuine CBT — free, no signup, nothing uploaded. What's different: extraction has two free paths. Our public Gemini GEM needs no API keys - upload PDF, paste JSON. Or let the built-in AI read papers page by Mistral, NVIDIA with checkpoint-resume so a rate-limited crash costs one page, not eighty. Diagrams are never AI-guessed — you drag a box on the actual PDF and that exact crop ships with the question. Papers live only in your browser's IndexedDB.

- EEExplainpaper – Explain jargon in academic papers with GPT-32022 · explainpaper.com · ▲223
heyo! Explainpaper lets you upload a research paper PDF. If you don't understand a formula or sentence, just highlight it and the tool explains it for you I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper). Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
