Think with everything you know.
Hi, I'm Wolfgang. I built ONA.UNO, and I'd like to tell you why.
Consulting projects. Software architecture. Research. Travel. Books. Politics. Science. Culture. News. Taxes. Household. Photography. Filmmaking. Gadgets. Conversations that mattered. Over decades, I've collected information across all of these, in every format imaginable: notes, emails, web clips, PDFs, documents, bookmarks. Because everything connects. Steve Jobs called it connecting the dots. I've always believed in that.
The dots were all there. But connecting them took a disproportionate amount of time and effort. Finding the right document. Locating the exact passage. Remembering which tool, which folder, what name, from when. And the hardest part: seeing that an email from January, an article from last summer, and a note from years ago all belong together.
Where do I save this? How do I tag it? Bookmarks, Readwise, Pocket, Bear, Apple Notes, Obsidian. Folders, tags, links, metadata. How do I find it again? How do I find what I didn't know I was looking for? Every few months, a new system, full of optimism. Evernote, then Notion, then Obsidian, then scripts I wrote myself. And every time the same thing happened: the system worked as long as I worked for the system. The moment I got busy with actual thinking, the organizing stopped. Within weeks, the same pile in a different app.
And then, gradually, something shifted. I stopped blaming myself for not keeping up. I started looking at the problem differently. Not "how do I get better at organizing?" but a quieter, more honest question: what if organizing itself is the wrong job? What if the real task isn't to build a better filing system, but to make one unnecessary?
That's where ONA.UNO began.
The insight
Your brain doesn't file things in folders. It connects them. You hear a phrase and it reminds you of a conversation from three years ago. You read an article and suddenly a half-forgotten idea clicks into place. That's how your mind works: by association, not by hierarchy. And it's brilliant at it.
Except it forgets. It can hold maybe a few hundred things in active memory, and you've saved tens of thousands. So most of what you know is effectively gone. Not deleted, but unreachable. Sitting in a folder you don't remember, in a tool you stopped using, under a name that made sense at the time.
What if your tools worked the way your mind works? Not by forcing you to organize, but by understanding what you saved and surfacing it when it matters?
That's ONA.UNO.
How this is different
ONA.UNO is built on a simple conviction: your knowledge already contains more answers than you think. You just can't reach them yet.
This isn't a filing system. It's not another app that asks you to learn its structure before it becomes useful. It's a tool that reads everything you've collected and makes it available to your thinking, instantly and associatively.
Here's what that means in practice:
Your knowledge stays where it is.
ONA.UNO doesn't replace your tools. Your files stay in their folders, your notes stay in Obsidian, your emails stay in Mail. ONA.UNO reads and indexes them. Nothing to import, nothing to migrate, nothing to reorganize. You keep working the way you work. ONA.UNO adds the understanding.
Everything becomes searchable by meaning, not just by name.
Search for "project deadlines" and find a note you titled "delivery timeline Q3." Search for "that argument about infrastructure spending" and find an email you'd forgotten about. ONA.UNO understands concepts, not just keywords, because that's how you think and that's how retrieval should work.
You don't read. You ask.
This is maybe the most important shift. You've saved an article, a report, a long email thread. In the old world, you'd have to reread it to use it. In ONA.UNO, you ask a question and get an answer, grounded in your sources, with citations you can click to verify.
Here's a small example. ONA.UNO itself has hundreds of pages of documentation. I could ask you to search through it. Instead, the app includes a "Chat with Knowledge Base" feature. You simply ask "How does semantic search work in mixed mode?" and get a precise, sourced answer. That's not a gimmick. That's the entire philosophy, applied to its own documentation. And it's exactly what ONA.UNO does with everything you've ever saved.
Structure emerges. You don't impose it.
Every item that enters ONA.UNO is automatically summarized, titled, tagged, and embedded. Not by you, by the system. You don't decide where things go. You don't maintain a taxonomy. You save something, and it finds its place. Over time, patterns appear. Topics cluster, connections surface, your library organizes itself.
This is the opposite of how most tools work. Most tools say: organize first, benefit later. ONA.UNO says: save now, understand always.
Who this is for
If you're still reading, you probably recognize yourself in this.
You've tried the systems. You've read the productivity books. You've set up elaborate workflows and watched them decay the moment life got busy. You're not lazy or disorganized. You're someone who collects a lot because you think a lot. And you're tired of tools that treat knowledge management as a filing problem.
ONA.UNO is for people who have already saved everything. It's for the moment after that, when you want all of it to actually work for you.
What it's not
ONA.UNO is not a note-taking app. You already have one. It's not a cloud service. Your data stays on your Mac, and AI runs through your own API key. It's not a startup that might pivot next quarter. It's a native macOS app built by a single developer who uses it every day.
There's no algorithm deciding what you should see. No company storing your thoughts on their servers. No subscription that holds your content hostage. Just your knowledge, made accessible, on your terms.
If any of this sounds like a problem you've been trying to solve, I'd be glad if you took a closer look.
