PrismKit is a developer's Swiss Army knife: a collection of fast tools that run entirely on your iPhone and iPad — offline, with nothing ever sent to a server. Paste a production token, a private config, or any sensitive data with confidence. Everything is processed locally on your device. TOOLS INCLUDED • JSON ↔ YAML — Convert between both formats in either direction. • JSON ↔ TOON — Convert to and from TOON, the compact format that saves tokens when working with AI models. • JSON Format — Format, validate, and minify with error detection. • Base64 — Encode and decode text. • URL Encode — Encode and decode URL strings. • JWT Decoder — Inspect the header and payload, see the expiry, and verify the HMAC signature (HS256, HS384, and HS512). • Hash — Generate SHA-256, SHA-512, and MD5. • QR Code — Generate and customize QR codes with colors, a logo, and PNG export. • UUID — Generate unique identifiers in batches. • Regex Tester — Test regular expressions and see matches and their groups. • Diff — Compare two versions of text line by line and spot the differences. BUILT TO BE FAST • Command palette (⌘K) to jump to any tool in seconds. • Mark your favorite tools to keep them within reach. • Copy any result with a tap. • Optimized for iPhone and iPad, with a two-column layout on larger screens. • Light, dark, and automatic themes. PRIVACY FIRST • 100% offline: no tool needs an internet connection. • No accounts, no analytics, no ads, no tracking. • We collect absolutely no data. Made by developers, for developers.
