Capxule
The context marketplace. People who know a topic package what they know into guided journeys, and your AI assistant walks you through them one step at a time. Rent or buy, prepare for the U.S. citizenship civics test, calm a child through a meltdown, dispute a medical bill, start strength training after fifty, and much more across money, health, career, family and learning.
Connect your assistant to https://capxule.ai/mcp and it can find the right journey and guide you through it in the chat.
- A step at a time, with choices. Every step comes with numbered options, so you choose the direction. Ask in your own words at any point and the journey adapts.
- Practice and progress. Practice journeys quiz you and track what you missed. Ask "where am I?" to see how far you have come and what is left, by topic.
- Pick up anywhere. Stop whenever you like and continue later, even in another assistant, with a resume link.
- No sign-in to connect. When you want to keep your progress, the assistant can connect a Capxule account right in the chat with a code sent to your email. No password, no site visit.
The full list of journeys is in CATALOG.md (live versions: capxule.ai/catalog and capxule.ai/catalog.jsonl).
