Testimonials
Loved by developers worldwide
The composer finally feels like a dev tool — rich text for context and Monaco for the actual snippet, all in one card.
I live in the language picker. TypeScript, Go, SQL — switching syntax highlighting without leaving the page is huge.
The library grid and three-dot menu make it easy to clean up old snippets. Delete confirmation saves me from mistakes.
FAQ
Common questions
Everything you need to know before you get started.
What can I put in a note?
Each note has a plain-text title, a rich-text body (headings, lists, links, tables, inline code), and an optional Monaco code snippet with your chosen language.
Which programming languages are supported?
The snippet editor supports 35+ languages including TypeScript, React (JSX/TSX), Node.js/JavaScript, Python, Go, Rust, SQL, GraphQL, and more — organized in grouped categories.
How do I edit or delete a note?
Open your workspace or the full library, click the ⋮ menu on any card, then choose View, Edit, or Delete. Deletes ask for confirmation first.
How does authentication work?
We use Clerk for secure sign-in. Your notes are stored in the cloud and tied to your account — only signed-in users can manage notes.
