Discover your true self
The world’s best private AI journal
Saga is the only consumer AI product I use, and when I’m using it, it’s more than 4 hours a day. The only useful AI product that isn’t for work.

What happened today?
Second date with Marcus at Cervo’s. 50/50 martinis, the prawns. Did the polished-version thing again. Walking home, kept thinking, “is this real?”
“is this real” — 3 matches
with Daniel, with Theo — same line, “is this real.” The pattern isn’t the men; it’s the armor you bring to the table. What would dinner look like without it?
yeah, that lands. since Daniel ended I haven’t trusted my own read on anyone — “is this real” is me doubting myself, not him. log all of this
My Story
I built Saga during a time when everything in my life was falling apart and the world felt more uncertain than ever.
Like many people, I turned to AI. I told it all of my thoughts, my feelings, my story—and it gave me clarity. The more honest I was with it, the more I learned about myself in ways I could never get from talking to others. Eventually, I started talking to AI every day, almost every moment I could. I treated it like a diary.
But there was a problem. The things I was telling AI were so intimate, and I didn't trust what these companies would do with my information. The AIs out there were built for productivity, making money, or extracting data—not the kind of self-discovery I wanted.
So I built the AI I always wanted—powerful, fast, beautiful, and private. A partner I could tell everything to, so I could better understand myself. Most importantly, one I could trust. I didn't want anyone to have the most intimate details of my life except me—not kept on a corporate server somewhere I couldn't control.
As I used it more, my thinking became clearer, I felt calmer and more certain about my decisions, and I became more open about what I discovered about myself with others. It became an incredible mirror that could help me master myself and connect more meaningfully with others.
I built Saga for myself. Now I want to share it with you and the world.
I'm Jon, an indie developer building Saga as a one-person team with no outside investors. I built Saga this way to ensure the right incentives are in place to protect your privacy and build the best tool for personal reflection possible. You can learn more about who I am and what I've worked on at my website.
Saga is completely user funded with a monthly subscription you can cancel anytime. No ads, no data sales, and no pressure to extract more from you. I answer only to you.
During the beta period, Saga is $20 per month. You can cancel anytime, no questions asked.
Saga is iOS only during the beta period. Joining the waitlist gets you in line for a TestFlight invite. Android, Windows, and Linux aren't supported yet but will be coming soon. If you want to sync your Saga data for use with other applications, there is a desktop application available for Mac users.
Not yet. Saga is still in beta while I refine the product, pricing, and reliability. You can participate in the beta and get notified when Saga is in the App Store by signing up for the waitlist.
Saga has the strongest privacy on the market. Your conversations and journal are end-to-end encrypted at rest and in transit, and the only way to access your data is with your password on your devices. We use the same zero-knowledge strategies as other privacy-focused applications like Signal, WhatsApp, and Bitwarden. I can't access your stored data and it's impossible for me to hand over your data to anyone.
Your vault is the encrypted container for everything you put in Saga — every conversation, journal entry, and reflection. The only way to access your vault is using your password and it is never stored anywhere. You are the only person to have access to your vault.
There's no way to recover your vault — not by me, not by anyone. That's the tradeoff for genuine zero-access encryption: if a recovery mechanism existed, the privacy promise wouldn't hold. Save your password somewhere safe before you risk forgetting it.
Saga is built for personal reflection, not work — the interface and tone are designed for self-discovery, not productivity. It's fully private and always will be: no ads, no data sharing, no training on your conversations. And it keeps a journal for you, which gives Saga far better memory than tools that reset every session.
Yes. Your Saga data is stored as plain markdown files in your vault, and the desktop app syncs them to your computer. From there, any tool that reads files — Claude Code, Codex, Cursor, your own scripts — can use them as context.
Yes. Your vault syncs to your computer as plain markdown files via the desktop app — point Obsidian at that folder and your entire journal is readable, editable, and searchable inside Obsidian, with graph view, plugins, and everything else Obsidian offers. Your data isn't locked into Saga.
