What is CheatGrid? Most references are a wall of prose, or stop at the obvious basics. CheatGrid is different: every topic is a cheat sheet broken into clean concept, example, description tables, sorted from most-used to most-advanced, with an interactive mind map and a quick index. Each sheet...

As answered by people managing Sejda and CheatGrid.
CheatGrid's answer:
Every cheat sheet uses the same consistent 3-column format (concept → example → description), ordered from most practical to most advanced. Most resources cover only the obvious top 20% — CheatGrid covers the full topic including edge cases and advanced patterns. Every topic also comes with an interactive Mind Map, and the platform combines reference lookup with practice tests, certification prep, XP tracking, and a personal vault — all in one place.
CheatGrid's answer:
Tools like devhints.io and OverAPI are community-contributed with no consistent structure. CheatGrid uses a single carefully designed format across all 1300+ topics, sorted by real-world importance rather than alphabetically. It goes beyond lookup — practice tests, certification study guides, Mind Maps, and progress tracking mean you can learn and certify, not just reference.
CheatGrid's answer:
Developers, data engineers, DevOps professionals, cloud architects, and tech professionals who regularly look things up at work, prepare for technical interviews, or study for certifications. Also used by students and career-switchers entering the tech industry.
CheatGrid's answer:
Built out of frustration with spending 30+ minutes a day re-searching the same answers across dozens of tabs and articles. The idea: one structured, consistent place for every technical topic — not a wiki, not a forum, but a reference you can scan in seconds and actually trust.
CheatGrid's answer:
Next.js, React, TypeScript (frontend); Convex (backend/database/auth); Python + FastAPI (AI chatbot RAG pipeline); Vercel (hosting).
CheatGrid's answer:
Individual developers, data professionals, and engineers using it for daily lookup and certification prep.

This is a week late, but through the FreeMediaHeckYeah sub, I was able to discover sejda.com , which is basically an (almost) all-in-one PDF editor website. Was neat to realize I didn't even have to download any software whatsoever. Source: over 3 years ago
Sejda.com - By far my most favorite experience but limits you to a # of docs per day. Source: about 4 years ago
Might try sejda.com. Also as u/jakethepeg111 suggests, Libreoffice Draw could be an option. Source: about 4 years ago
