Building Fold.tao
We wanted a notes app that didn’t feel like a chore to use. Most note-taking tools either force you into a rigid hierarchy or leave you drowning in a sea of disconnected markdown files.
The Architecture
We built Fold.tao using a simple, local-first architecture.
Capture first: The UI opens instantly to a blank slate.
Organize later: Background workers categorize notes using lightweight LLMs.
Sync silently: Data is encrypted and synced without loading spinners.
The Stack
Typescript
interface Note {
id: string;
content: string;
vector: number[];
createdAt: number;
}We rely heavily on vector embeddings for search. It allows the system to find what you mean, not just what you type.
