vji — AI Cheat Sheet Maker

vji — AI Cheat Sheet Maker for Students, Developers and Creators

Paste your notes or drop in an image, pick a style and an aspect ratio, and vji hands back a clean, shareable cheat sheet in seconds. No design skills, no prompt writing.

How it works

1. Input — paste text (up to 5,000 characters) or upload up to 10 images (screenshots, handwritten notes, slides). PDF is not supported yet.
2. Choose — pick a style and one of 16 aspect ratios (default 2:3, from 1:1 to 21:9).
3. Generate — submit once. The prompt is assembled by vji, not by you. Download, print, publish to the public gallery, or share the link.

Who it's for

• Students & exam prep — turn scattered notes into one revision sheet.
• Developers & ops — command, config and API references.
• Creators & knowledge workers — visual summaries of articles, talks and research.

Highlights

• Prompt written for you. Input template → style → content rules → watermark, assembled in four layers. You only make choices.
• Any aspect ratio. 16 presets including portrait, landscape, square and ultra-wide.
• Reference images supported. Drop in a screenshot or a photo of your notes and it becomes the source.
• Public gallery or private. Paid generations start private; you decide when to publish.
• Bilingual & dark mode. English and Chinese UI, light/dark themes.
• Runs on the edge. Single Cloudflare Worker with D1, R2 and KV — fast, no servers to babysit.

Pricing

Free forever tier: 3 credits a day, one generation costs 2 — enough for a sheet every day, watermarked.
