Why you'll like it
Faster than opening a notes app
Ideas tend to show up at the worst times: in the shower, on a walk, halfway through something else. IdeaBox is built so you can save one in a few seconds and get back to what you were doing.
Type a line, record a voice memo, snap a photo, paste a link, or scan a page with the camera. Everything lands in one place, and folders with their own icons and colors, plus tags, filters, and search, mean you can actually find it again later.
A thinking partner when you need one
Some ideas stall after the first sentence. When that happens, brainstorm with Claude right inside the app. Type a topic and get suggestions and new directions to explore, next to the notes you already have.
There's also Daily Spark: one creative prompt a day, at a time you choose. It's a small habit that keeps you thinking even on days without a big idea. The free plan includes one AI brainstorm a day, and IdeaBox Pro raises that to ten.
From idea to plan
An idea only matters if something happens with it. IdeaBox lets you break an idea into milestones and nested tasks, then follow a progress bar from zero to done, with a little haptic feedback each step of the way.
To start faster, there are more than 50 templates, like an App Idea Canvas, a Business Model, and a Content Calendar. Widgets keep your top ideas on the Home Screen and Lock Screen, and you can export to PDF, CSV, JSON, or Markdown when it's time to move an idea into another tool.
