Silkworm Study
Study the way your mind connects.
Map ideas as fast as you think them. No dragging boxes. Just type, and the map lays itself out.
Free while in beta. No sign-up, no card.
Silkworm StudySpeed
Faster than pen and paper.
Most mind-map apps make you drag boxes around. Silkworm Study lays the map out for you, so your hands never leave the keyboard and your thinking never stops.
Link view
See only what connects.
Link any two topics and write on the line between them, like “causes” or “same idea”. Then one tap trims every branch that doesn’t lead to a link. Same map, same places, nothing deleted.
Links never get in the way: drag a line to bend it, slide its label along, and words always sit on top. Topics you’ve written twice get a ×2 badge, so you can hop between every place an idea appears.
Recall
Say it before you see it.
Recall hides every branch. Pick a topic, explain it out loud as if someone just asked, then reveal one branch at a time to see what you missed. It’s the fastest way to find out what you really know.
Key terms
A glossary that keeps up.
Keep a running list of terms beside your map and sort them into your own categories. Point at any topic on the map and its definition appears. Blur them all to test yourself.
- Osmosis
Water moving across a partially permeable membrane, from a dilute solution to a more concentrated one.
Biology - Opportunity cost
The value of the next best option you give up when you make a choice.
Economics - Treaty of Versailles
The 1919 peace settlement that ended the First World War and placed heavy terms on Germany.
History
Silkworm AI Pro
Definitions that write themselves.
Add a key term, leave the definition blank, and the AI fills it in. Pick plain or technical wording and how much detail you want. Anything it writes is marked, so you know what to check.
Two keys. No more typing out definitions.
Type a term into your glossary and press Return on the blank definition. Mapping fast? Press = at the end of any topic and it lands in your key terms, defined, while you carry on to the next point.
- Photosynthesis
How plants use light energy to turn carbon dioxide and water into glucose and oxygen.
AIBiology - Inflation
A general rise in prices over time, so the same money buys less.
AIEconomics - Mitosis
Cell division that makes two identical copies of the original cell.

And the rest
The details are done.
Photos on the paper
Drop in diagrams, photos or screenshots. They float beside your map with captions and resize with a drag.
Links that bend
Drag any link out of the way and slide its label along. Words always stay on top.
Definitions on hover
Any topic that matches a key term shows its definition when you point at it.
Arrow keys, mid-thought
Hop between topics while typing. Blank branches tidy themselves away.
Paste a list, get a map
Paste notes from anywhere. Every indented line becomes its own branch.
Search everything
Find any topic or key term across every map in one keystroke.
Spots repeat topics
Write an idea twice and it’s flagged. Headings like “Diagnosis” are ignored, and you choose the rest.
Undo anything
Every change, even halfway through typing, is one ⌘Z away.
On every device
Mac, iPad, iPhone or any browser. Maps and key terms sync as you go.
Why it exists
Your mind already works this way.
Thoughts don’t arrive in tidy lists. They branch, loop back and connect, which is why mind maps are such a good way to learn. The problem is the software: in most mind-mapping apps, drawing the map takes longer than having the thought.
Silkworm Study is built to get out of the way. Type, press Tab or Return, and the map lays itself out as fast as the ideas come. Then link anything to anything, and test yourself on it.

Questions
Good to know.
What do I get in the beta?
Everything, free: unlimited maps, links, key terms and photos, plus AI definitions. When the beta ends, the free plan keeps three maps, Standard gives you 30 and Pro removes every limit.
Where are my maps saved?
During the beta, in your browser on the device you use. Nothing is sent anywhere except the terms you ask the AI to define. To keep a copy or move to another device, open the menu and choose Back up all maps, then Restore from backup on the other device. Accounts that sync across devices are coming.
What does the AI do?
On Pro, the AI writes key-term definitions for you. Leave a definition blank and press Return, or press = at the end of any topic on your map. Choose technical, moderate or plain wording, and low, medium or high detail. AI-written definitions are marked so you know which ones to check. Pro includes up to 1,000 AI definitions a month, far more than a heavy study week needs.
What can I use it for?
Anything where ideas connect: exam revision, lecture notes, essays and research, learning a language, or planning a project. If you’d sketch it on paper, it’s faster here.
Which devices does it work on?
Any modern browser on Mac, iPad, iPhone, Windows or Android. During the beta, each device keeps its own maps; Backup and Restore move them across.
Can I get my work out?
Yes. Copy any map or your whole glossary as clean text that pastes neatly into documents, flashcards or anywhere else.
Can I cancel anytime, once plans start?
Yes. Your plan runs to the end of the month or year you’ve paid for. Nothing is ever deleted: if you’re over the free limits, your maps stay open to read and copy, and you just can’t add more until you upgrade.
Your next exam, mapped.
Start with the topic you’re most worried about. It’s free while in beta.
