A few thoughts. An outline that grows.

Maybe it’s a guide you’ve been meaning to write.
Nest an example under an idea. Move a branch as your thinking changes.
Fold the details to see the whole. Your guide starts to find its shape.

A sample guide’s outline in Moss: ideas, sources, and next steps nested in branches, with the draft beside it. On a phone, a closer view of the outline.

Interactive demo · Sample conversation, no live AI · Edits reset on refresh.

Now there’s something
to work with.

In Moss for Mac, ask AI to work with your outline: compare the sources you’ve gathered, suggest a structure, or help write the opening.

Keep what helps. Reshape it in your outline.
The next version is yours to shape.

Tomorrow, you’re not
starting over.

Your outline holds more than the draft: the sources behind it, the decisions you made, and what’s left to do. When a better example comes to mind, there’s a place for it.

Your guide doesn’t have to be finished today.
Just ready for the next thought.

What have you been
meaning to make?

Bring your own first few lines to Moss for Mac.
See where they take you.

Apple Silicon · Bring your own model provider

What do I need to use Moss?

A Mac with Apple Silicon. Connect a supported model provider to work with AI.

Does “local-first” mean AI runs offline?

No. Your desktop workspace is stored locally. AI requests send task context to the model provider you connect.

What about pricing and model costs?

Review the current release’s license. Model access and charges depend on your provider; downloading Moss does not include model usage.
