The Carbon Cycle — Core Idea
Carbon is recycled between Earth’s major reservoirs. Photosynthesis moves it into living matter; respiration, decay, and combustion return it to the atmosphere.
Remember these
- The cycle moves carbon; it does not create or destroy it.
- Oceans and rocks are major long-term reservoirs.
- Human combustion increases atmospheric CO₂.
Made for real-world captures
From “save for later” to ready when you need it.
CaptureNote works best on the things that are hard to summarize yourself: a dense slide, a diagram with arrows, a page full of definitions, or a screenshot that you know you will forget.

Starter Web Credits
Enough to test CaptureNote on 1–3 real images. No credit card required.
Web Credits only pay for cloud AI processing. They are separate from the one-time-purchase iPhone app.
Questions, answered
Good to know.
How much can I try for free?
New Web accounts start with 3 Credits, typically enough for 1–3 real captures depending on the image and output length. Web Credits are separate from the iPhone app and are never shared with it.
Is the Web version private?
The Web version sends the image to a selected multimodal AI provider so it can generate a note. We use short-lived processing and do not use your images for model training. The iPhone app is the local-only option when the source is sensitive.
What kinds of images work best?
Clear screenshots, textbook pages, presentation slides, whiteboards, and diagrams work well. Keep the important text large enough to read and avoid combining several unrelated pages into one image.
Can I keep the result?
Copy the Markdown or download a clean .md file from the result panel. The iPhone app adds a local library with folders, search, and Shortcuts for a more permanent workflow.
