Every thought
leaves a mark.
Stop saving then burying. Every article, thread, and video builds into a personal knowledge graph — your AI companion for thinking, publishing, and learning.
"You've saved 500 bookmarks. Good luck finding the one you need."
You read a brilliant thread about pricing strategy last month. Now you need it for your pitch deck. But it's buried somewhere in 47 browser tabs, 12 Notion pages, and a Telegram saved messages graveyard. Sound familiar?
Three steps to knowledge clarity
No folders. No tags. No organizing. Just save and ask.
Save from anywhere
Browser extension, mobile share sheet, or API. Save X threads, YouTube videos, articles, podcasts — anything with a URL.
AI extracts knowledge
Not just text — entities, claims, and relationships. Your content becomes nodes in a graph that grows smarter with each save.
Ask, don't search
"What did I save about pricing?" — get answers with sources, not 47 blue links. Your knowledge, conversational.
One brain. Three superpowers.
Talk to your knowledge. Publish from it. Expand it — without leaving the conversation.
Talk to your knowledge base
Ask anything across everything you've ever saved. Get synthesized answers with sources — like having a conversation with the smartest version of yourself.
Publish without starting from scratch
"Write a post about the AI trends in my knowledge base." One prompt. Your ideas, your voice, across X, LinkedIn, newsletters — automatically.
Go deeper, on demand
Ask the agent to research any topic on the internet — grounded in context from your own KB. Not just information, but insight that builds on what you already know.
Your knowledge. Your voice. Your edge. → an extended-knowledge self that learns, publishes, and researches with you.
Built for people who think for a living
True knowledge graph

Researchers & Analysts

Sources, quotes, background research — never start from scratch when you've already done the work.
What knowledge workers are saying
"I've tried every PKM tool. Mindmarks is the first one that actually helps me find things without organizing them first."
"The graph view is addictive. I can literally see connections between ideas I saved months apart."
"Finally, a tool that handles X threads properly. I save dozens a day and Mindmarks just gets it."
Questions about your personal knowledge graph
What is a personal knowledge graph?
A structured representation of your saved knowledge where entities, claims, and relationships are extracted by AI and connected into a navigable graph you can query conversationally.
How is Mindmarks different from Notion or Obsidian?
Notion and Obsidian are note-taking tools that require manual organization. Mindmarks automatically extracts knowledge from anything you save and builds a graph you can query with natural language. No folders, no tags, no organizing needed.
Is my data private?
Yes. Mindmarks is local-first — your knowledge stays on your device. Process with local models. No cloud required. Your personal knowledge graph is truly yours.
What can I save to Mindmarks?
Anything with a URL — X threads, YouTube videos, articles, podcasts, Facebook posts. Use the browser extension, mobile share sheet, or API.
How does the knowledge graph work?
When you save content, AI extracts entities (people, concepts, companies), claims (statements with evidence), and relationships (how things connect). These become nodes and edges in your graph, growing smarter with each save.
Is Mindmarks free?
Mindmarks is in early access and free to join. No credit card required. Sign up with your Google or GitHub account to start building your knowledge graph.
