About Manifold
LLMs have made it fast to turn an idea for a product feature into a working prototype. The slow part is now everything after: getting the right people to try it, collecting feedback that is specific enough to act on, and keeping track of the versions that follow.
Manifold is a place for that. You upload a prototype as a single self-contained HTML file, a micro instance, and share a link. Reviewers use it like the real thing, then pin comments and draw directly on it. Each iteration becomes a branch in a tree, so the history of an idea stays readable.
How it works
- Projects and micro instances. A project holds the micro instances you are working on, for example one per feature.
- Versions in a tree. Every upload is a version with a parent, so you can fork from any point and see how the idea evolved.
- Comments tied to the interface. Notes and drawings attach to the element you pointed at and follow it as the prototype scrolls, re-sorts or changes screens. Clicking a comment takes you back to the screen it was made on.
- One link to share. Anyone with the link can try the prototype and comment. People without an account just type their name.
What we believe
Feedback belongs on the thing
A screenshot in a chat loses the screen, the state and the scroll position. Comments should live on the prototype, in context.
Iterations are cheap, so keep them
When an LLM can produce a new version in a minute, you need a way to branch, compare and remember what each version was for.
Untrusted by default
Prototypes are arbitrary code. They run in an isolated sandbox on a separate address and can never reach your account.
No account needed to react
Anyone with a share link can try the prototype and leave a comment with just their name.
Manifold is in early access and free to use.
