Frequently asked
FAQs
Answers to common questions about projects, canvases, and AI features.
1. What’s the difference between a Project and a Canvas?
A Project is the container for a product/initiative. A Canvas is where you build and connect invention ideas inside that project.
2. How should I structure a canvas?
Start with nodes for the problem, core solution, key components, data flow, and benefits. Add variants/alternatives and connect nodes to show how it works end-to-end.
3. What are nodes, and what should go in a node?
Nodes are the building blocks of your invention narrative. Include what it is, how it works, inputs/outputs, edge cases, and alternatives—written clearly enough that someone else can follow.
4. Why connect nodes?
Connections document relationships and dependencies (e.g., data/control flow). This improves clarity and makes it easier to turn your canvas into a patent-ready description later.
5. Can AI help me write node content?
Yes. AI can draft, rewrite, and expand technical descriptions, suggest missing elements, and propose variants. Treat it as a starting point and always review for accuracy and novelty.
6. What should I do when AI suggestions feel generic?
Add more specifics: constraints, system boundaries, concrete steps, thresholds, failure modes, and implementation options. The more grounded details you provide, the better the output.
7. What is AI Analytics used for?
AI Analytics helps you assess your work from multiple angles (clarity gaps, differentiation opportunities, completeness). Use it to iterate before sharing with counsel.
8. How does the Learning section help?
Learning provides practical guidance on patents and how to describe inventions. Use it to strengthen descriptions, avoid common pitfalls, and improve the structure of your canvases.
9. How do subscriptions and limits work?
Plans can control feature access (e.g., collaboration/AI usage) and may include daily AI limits depending on tier. When you hit limits, you can still view/edit your work, but AI features may pause until reset or upgrade.
10. How do I send feedback or report a problem?
Use the Feedback option in the app. Include what you were doing, what you expected, what happened instead, and which project/canvas you were in—this speeds up troubleshooting.
