Everything your words need

One workspace for writing, organizing, securing, and shipping your Markdown.

Live dual-pane preview

Write on the left, watch it render on the right. A distraction-free editor that keeps you in flow.

Encrypted at rest →

Your document body and every saved version are stored with AES-256 encryption. Private by default.

Folders, tags & history

Nested folders, color icons, tags, and automatic version history on every change.

Image pipeline →

Uploads convert to WebP and fit a web budget, so shared pages stay fast.

Knowledge layer →

MarkNest turns your Markdown into a queryable knowledge base. Every document is chunked, embedded, and indexed, so an AI assistant can pull the exact passage instead of guessing.

Your nest, wherever you write.

A focused space on Mac. A thought captured on iPhone. More room to work on iPad. Native apps are on their way.

Expiry date

Auto-revoke access after a set time.

Privacy is the default

MarkNest encrypts your writing at rest with AES-256. Encryption is transparent: you just write, and the protection comes built in.

How encryption works →

Document body

Raw Markdown is encrypted before it touches the database.

Rendered HTML

The cached render is encrypted alongside the source.

Every version

Each saved revision in your history is encrypted too.
