Second Brain, Automatically · Private Beta

Capture everything.
Never lose a thought.

Paste a link, drop a file, or record a voice memo. Praxis AI automatically links it into a knowledge graph, so you can chat with your own notes — with citations — and see how everything you've ever saved actually connects.

The Problem

Your notes app is a graveyard, not a brain.

You save everything — articles, voice memos, half-formed ideas, meeting notes. Then you never see most of it again. Search only finds what you already remember the exact words for. Tags and folders take upkeep nobody actually does.

A real second brain isn't a pile you write into — it's a web of ideas that connects itself, so a note from six months ago surfaces exactly when it's relevant, and you can just ask it a question instead of digging.

That's the gap Praxis AI closes.

How It Works

Capture. Organize. Chat. Explore.

01
Capture
Paste text or a link, upload a file, or record a voice memo. It's saved instantly — no folder to file it into, no tag to remember.
02
AI Organizes
In the background, AI figures out how each new capture relates to everything you've saved before, and links it into your knowledge graph automatically.
03
Chat
Ask a question in plain language. Get an answer pulled from your own notes and their connections — with citations back to the source.
04
Explore
Browse your second brain visually — an interactive graph you can click through, the way your ideas actually connect.

Why Praxis

Not just another notes app.

A real knowledge graph, not just tags
Every capture gets linked to what it's genuinely related to — reasoned by AI, not just keyword or folder matching.
Graph-aware chat, not flat search
Answers pull in connected notes, not just the single closest match — so context you forgot you had still shows up.
Voice-first capture
Record a thought while it's fresh. It's transcribed and organized automatically — no typing required.
Built honestly, in the open
Built by one person, documented as it's built. No fake team page, no vaporware screenshots — what you see here is what's actually true today.
Common Questions

Things people ask.

Is this live yet?
Not yet — it's actively in development. This page exists to collect early interest before the private beta opens. Join the waitlist to hear when access opens.
I already use Notion / Obsidian / Mem. Why switch?
Those are places you write into. Praxis AI is the layer that automatically organizes and connects what you capture — you don't have to build the structure yourself, and you don't have to remember where you put something.
What does "AI-built knowledge graph" actually mean?
Every note you capture gets compared against your existing notes. When the AI decides two are genuinely related, it draws a link between them — with a reason. Over time that becomes a graph you can browse and ask questions of.
Is my data private?
Your captures and graph are yours — not used to train anything, not visible to other users. Full data-handling details will be published before public launch.
