Features

Built around
how you think.

notx does a lot. Here is what matters — the capabilities that make the difference between software that serves you and software you serve.

01 Notes & Organization

Start with a thought.
Build from there.

Every note is a living document. Write, search, and organize without friction. Structure emerges naturally — you never have to plan it upfront.

Instant notes Ctrl+N
Create a note in one keystroke. No template required, no decisions upfront. Start writing immediately.
Auto-save
Everything saves as you type. There is no save button. You can close the tab without thinking.
Spotlight search ⌘P
Full-text search across every note, instantly. Keyboard-navigable. Find anything in seconds.
Projects & folders
Organize with top-level projects and nestable folders. Drag to reorganize. An Inbox holds anything that doesn’t fit yet.
Import from URL
Paste any URL. notx fetches the page and creates a note as a TL;DR summary or full extracted text.
02 Visual Thinking

See your ideas
take shape.

Write structure in plain text and watch it become a diagram. No drawing tool. No manual arrows. Your thinking goes visual the moment you need it to.

Mermaid diagrams
Flowcharts, sequence diagrams, mindmaps, ER diagrams, quadrant charts, timelines — all from plain-text syntax.
Canvas & custom types
Free-form canvas, funnel & pyramid, HTTP collections, Vega-Lite data charts, and SQL ER auto-generated from DDL.
Three render styles
Switch between clean vector, rough hand-drawn, or ASCII box-art at any time. The chosen style is preserved on export.
Split view
Editor and rendered diagram side by side. Or go fullscreen on either. Toggle with a single key.
Node linking
Double-click any diagram node to navigate directly to a linked note. A breadcrumb trail lets you trace your path back.
03 AI Thinking Partner

Ask questions.
Get answers from
your own notes.

The AI reads your notes and thinks with you — not at you. Ask in plain language, create diagrams from descriptions, find connections you hadn’t noticed.

Ask panel
“Show me recent architecture notes.” “Summarize what I have on this project.” Natural language, grounded in your content. Answers cite the source notes they drew from.
Create from description
Describe a diagram in plain language. The AI generates the Mermaid code and offers to save it directly to a project.
Beautify
Rewrites messy or hand-written Mermaid into clean, consistent structure — without changing the diagram’s meaning. One click.
Meaning
Summarizes any diagram or note in plain language. Useful for sharing context quickly or checking your own thinking.
Your key or ours
Connect your own OpenAI API key for zero markup, or use notx-managed AI at OpenAI list pricing + 3%. No lock-in either way.
04 Tasks

Action lives inside
your thinking.

Tasks are markdown checkboxes in your notes. The Tasks panel extracts them all automatically. Check a box anywhere and it syncs back to the note in real time.

Source-linked
Every task traces back to the note it came from. Click the note name to navigate there directly.
List and kanban
See all tasks in a flat scrollable list, or drag cards across Backlog, Doing, and Done columns. Both views stay in sync.
Due dates & overdue
Calendar badge on any task with a due date. Overdue tasks are highlighted in red across both views.
Scope filter
View tasks from a single note, a project, a folder, or everything at once. Focus to what’s relevant right now.
05 Guided Presentations

Share how you think,
not just what
you think.

Record a walkthrough of any diagram — highlight nodes, pan, zoom, select text. Anyone can replay it and follow your reasoning step by step.

Record interactions
All canvas interactions are captured with timestamps — node highlights, scroll position, pan/zoom, text selections.
Transcript
A scrollable log of every recorded event. Click any item to jump to that exact moment in the playback.
Multiple guides per note
Save and manage several named recordings for the same note. Different audiences, different walkthroughs.
Playback controls
Pause, resume, stop. The canvas animates through each captured event exactly as it was recorded.
06 Publish & Share

Publish on your terms.
Share without
losing control.

Any note can become a public URL. Gate it by email, protect it with a password, set it to expire. Comments optional. Private by default.

Public URL
Publish to a unique /p/slug readable by anyone without an account. Includes an OG image for rich link previews in Slack, email, and social.
Access control
Restrict to specific email addresses, protect with a password, or set a link expiry at 7, 30, or 90 days. Any combination.
Comments
Enable a comment form on any published page. Anonymous by default, optional name. You moderate from the Publish panel.
In-app sharing
Grant another notx account viewer or editor access inside the app — separate from public publishing, no URL required.
Revoke instantly
One click unpublishes. The URL returns 404 for all visitors immediately. No waiting period.
07 Version History

Every version is kept.
Nothing is
ever lost.

Every edit is recorded in a full event log. Browse your note’s entire history, see exactly what changed, and restore any version with a single click.

Event log
Changes grouped by day and session. Each event shows the time, a plain-language change summary, and the session duration.
Diff view
Side-by-side comparison of any two versions. Added lines highlighted green, removed lines red. The rendered diagram updates live as you navigate.
Restore
Roll back to any event. The restore itself is recorded as a new event — fully undoable. You can never permanently break a note.
Quick undo
On the most recent event, a one-click Undo reverts the last change without going through the full restore flow.
08 Local & Private

Your data
on your machine.
Or ours. You choose.

Run notx against a local server on your own hardware — no cloud storage required. Or use our cloud. Either way, you decide where your data lives.

Local server pairing
Generate a pairing token, run notx-engine pair, and your local server appears in the app. Three steps, five minutes.
No cloud required
The desktop client works in full local mode — no account, no internet, no dependency on our servers. Your notes never leave your machine.
Connection picker
Switch between cloud storage and any paired local server instantly from settings. The editor updates immediately with no data migration.
Mutual TLS security
Pairing uses mTLS — the platform acts as the certificate authority. Certificates renew automatically every 30 days. Revocation is instant.
