Cantera: Code Snippets & Ideas

Capture from anywhere. Screenshots become searchable, notes file themselves, and everything exports as plain Markdown. One-time Pro, no subscription.

Ideas don't wait. The good ones show up while you're doing something else — and they're gone before you find somewhere to put them.

Cantera is where they land.

CAPTURE FROM ANYWHERE Share a screenshot, a link or a snippet straight to Cantera from any app. Point the camera at a whiteboard. Dictate to Siri. There is no account and nothing to set up — capturing costs one gesture, always.

SCREENSHOTS STOP BEING DEAD ENDS Cantera reads the text inside every image, on your device. That folder of forgotten captures becomes something you can actually search — months later, by the words that were on the screen.

FILING HAPPENS WITHOUT YOU Every note lands sorted as a task, an idea or a reference, tagged on its own, with dates pulled out of plain language. A small model trained on development and design vocabulary ships inside the app and runs on any iPhone. Correct it whenever it's wrong — it learns nothing and asks nothing.

BUILT FOR PEOPLE WHO BUILD Paste a snippet and it's treated as code: straight quotes, no autocorrect, no wrapping. Turn any note into a ready-made prompt for your AI assistant. Let Shortcuts read and write your notes so they flow into whatever you already use.

FIND IT AGAIN Search covers titles, your words, tags — and the text read from your images, with every result saying where it matched. A reference board for what you saved to look at. A review screen for what slipped. A map of notes that resemble each other, so you don't save the same thought five times.

YOURS No account, and nothing you write ever leaves this device — not a note, not a tag, not a search. Your notes export as plain Markdown whenever you want them elsewhere. What does leave is anonymous: which screens get opened, whether the app crashed, and whether you bought Pro.

CANTERA PRO — ONE PAYMENT, NO SUBSCRIPTION Sync across your devices through your own private iCloud, and keep a live folder of Markdown files your Mac can read. Everything else is free forever.
