I've read through your last three days of journal entries. Here's what stands out:

Energy pattern: Your best thinking happens in the morning before 11am. The afternoon entries are more reactive—responding to others rather than creating.

Recurring theme: You're still struggling with saying no to people and holding your boundaries. This came up with your manager on Monday and again with your sister yesterday.

Progress: Your anxiety about the presentation has shifted. Three weeks ago you called it "terrifying"—yesterday you described it as "challenging but manageable." That's real growth.

Would you like to explore any of these patterns more deeply?

My Story

Saga is the most advanced personal AI that captures your life story and helps you make sense of it

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.

FAQs

How is my data stored?

Everything stays on your Mac. Your conversations are stored locally in plain markdown files that you own and control. Nothing is uploaded to the cloud. You can read, export, or delete your data anytime.

How is this different from ChatGPT?

ChatGPT resets every conversation. Saga maintains one continuous conversation forever. It builds a timeline of your life and actually remembers what you told it last week, last month, or last year. It's the difference between talking to a stranger and talking to someone who knows you.

What AI models do you use?

Saga uses state-of-the-art open source AI models, optimized for deep personal conversation. We use your conversation history to provide context, so the AI actually understands who you are.

Does it work offline?

Saga requires an internet connection to communicate with AI models. However, all your data is stored locally—so your journal and conversation history are always accessible, even offline.

Is it only for Mac?

Currently, yes. Saga is a native Mac app available for both Apple Silicon and Intel Macs. We're focused on making the Mac experience exceptional before expanding to other platforms.

Can I export my data?

Absolutely. Your data is stored in standard markdown files on your computer. You can open them in any text editor, back them up however you like, or move them to another app. Your data is truly yours.
