Encrypted Markdown workspace Write Markdown in a calm, private space
A focused dual-pane editor with at-rest encryption, version history, sharing controls, and a REST API.
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.
Share on your terms
Publish a document or hand off a single file with a link you control. Every link carries its own access rules, and you can revoke it any time.
Explore sharing controls →Password
Lock a link behind a passphrase.
Expiry date
Auto-revoke access after a set time.
View limit
Cap how many times a link opens.
Download & copy
Toggle saving and copying per link.
Watermark
Mark shared pages as yours.
Email allowlist
Restrict access to named recipients.
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.
Let AI save notes where you write
Connect ChatGPT, Claude, or any MCP-ready assistant. Ask once, and a conversation summary lands in the right workspace with folders, tags, and files attached.
28 tools
Read and write documents, folders, tags, files, and run semantic search over MCP.
Organized by default
Saved with titles, folders, tags, and attachments ready to review.
Save our discussion above into MarkNest.
{
"title": "MCP integration discussion",
"folder": "AI Notes",
"tags": ["mcp", "meeting-notes"],
"format": "markdown"
}Saved to MarkNest as "MCP integration discussion". Your recap is ready with folders, tags, and source context attached.
Give your AI a memory of your writing
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.
Hybrid search
Vector cosine over pgvector plus keyword leg over Meilisearch, fused with Reciprocal Rank Fusion.
Two MCP tools
marknest_search_chunks and marknest_get_chunk, gated by the rag:read API key ability.
Find what I wrote about pgvector HNSW indexes.
{
"query": "pgvector HNSW index",
"limit": 5
}Top match: "Roadmap 11 — pgvector chunking" → "HNSW index for cosine similarity over 1536-dim embeddings, tuned for recall at low cardinality."
A REST API for your content
Authenticate with a scoped API key and read or write documents, folders, tags, and files from any workflow. Fine-grained abilities keep each key to exactly what it needs.
curl -H "Authorization: Bearer mk_your_api_key" \
