CosmoKnowledgeMap, an iPhone app that turns web pages and notes saved from Safari into a 3D map of stars and connections, is free on the App Store for a limited time. New Mobile Life lists its regular price as US$0.99. Neither source gives an end date, so the offer can change at any time.
What does CosmoKnowledgeMap do?
It is a personal knowledge map. According to the App Store listing, pages and notes you collect become stars, and the links between them become lines you can follow. You can save from the Safari extension, the Share Sheet or by typing an entry yourself. The listing calls the app CosmoMap in its description.
Features named on the listing:
- Fast full-text search, with a jump from a result to its star and on to connected items
- Four views of the same map: Sphere, Nebula, Neural Network and Plane
- Topic expansion: the app writes text you can paste into an AI tool you already use, such as ChatGPT, Claude or Gemini, and you import the reply. You can choose 30, 100 or 200 items. The listing says the app does not connect to AI services directly and needs no API key or extra payment
- A separate numeric passcode for each notebook, with Face ID or Touch ID on supported devices
- A sample Japan star map built from 50,000 Japan-related articles from Japanese Wikipedia and 151,153 real article links
- Cosmic Collapse, a game-like mode where you tear through and fling the stars of your own map, then close it to return to the original map unharmed
- An Ask tab, added in version 1.6, with on-device answers that cite your saved pages and notes
Is CosmoKnowledgeMap really free?
Yes, at the time of writing. The App Store listing shows the price as Free, and New Mobile Life says the regular price is US$0.99 and the free offer is for a limited time. Neither source gives a Canadian price, so check the Canadian App Store listing before you download. Prices and availability can change and can differ by country.
The listing is for iPhone only. The app is 22.7 MB, carries a 13+ age rating and supports English plus one more language. Apple notes that it is not verified for macOS.
Where does your data go?
The listing says imported information is stored on your device and that the app does not automatically send it to external servers. Using an outside AI tool is a manual step: you review and copy or share the text yourself. Pages from Safari Private Browsing are excluded from automatic capture. The sample data uses article titles and introductory excerpts from Japanese Wikipedia under the CC BY-SA 4.0 license.
Who it suits
Researchers and students who collect a lot of links. If you save pages across weeks of reading, full-text search plus a map of connections gives you a second way back to what you saved. Separate passcode-protected notebooks let you keep study, work and hobbies apart.
People who like to explore, not only file. The four views and the Japan star map give you something to browse before you add anything. Readers of Japanese will get the most from the sample, since it is built from Japanese Wikipedia.
Anyone who wants a light game mode. Cosmic Collapse is a play copy of your map, so it is a harmless way to try the app. It will not matter to you if you only want a plain notes list.
What is still unknown?
The sources do not say how long the app stays free or what it will cost afterwards. The listing has not received enough ratings or reviews to show an overview, so there is no independent feedback yet. It does not list an iPad or Mac version, and the interface is available in English plus one more language, which the listing does not name.
How do you get it?
Open the CosmoKnowledgeMap listing in the App Store on your iPhone, check that the price reads Free, and tap Get. If a price appears, the offer is over.
