vji — AI Cheat Sheet Maker for Students, Developers and Creators
Turn messy notes into clean, shareable cheat sheets. Paste your notes or drop in a screenshot, pick a style and an aspect ratio, and a finished sheet comes back in seconds — ready to share or print, with no prompt writing and no design skills required.
Two ways to get one
AI generation — turn just about any material into a sheet. Up to 5,000 characters of text, or up to 10 images: screenshots, photos of handwritten notes, slides. 15 aspect ratios from 1:1 to 21:9, or let Auto pick one from your content. Styles work the same way — choose one yourself or let Auto match it. Failed generations are refunded automatically.
Topic templates — exact, editable, free and unlimited. The site ships ready-made topics (the first is tmux). Every entry is finalized at build time and laid out in your browser, then exported straight to PNG. No model involved, no credits spent, no sign-in, no limits — every character comes from the template, so you can adjust as much as you like.
Look around
- Style library: every style in one place, each with its public sheet count and a preview — one click to generate with it.
- Public gallery: sheets users chose to publish, organised by category, browsable and searchable.
- Sheet pages: every public sheet has its own page, ready to download or share as a link.
Who it's for
- Students and exam prep: collect scattered notes into one revision sheet
- Developers and ops: commands, configs and API references
- Creators and knowledge workers: turn articles, meetings and research into postable cards
Your content stays yours
Sheets generated with paid credits start private and enter the public gallery only when you choose to publish. While your plan is active you can flip any past sheet between public and private. You can delete your records at any time. Free generations are watermarked and public.
