What's on your mind?

What's my visa status?

Your US visa interview is next Thursday at the consulate. Documents: passport, bank statements, employment letter. You said you're nervous — you've got this.

Did I buy concert tickets?

Yes — Hollywood Bowl next month, Dave is joining. You paid $180 for two tickets. You wanted dinner in Hollywood before the show.

Where did I put my passport photo?

You mentioned it during your visa interview prep — it's in your desk drawer, along with bank statements. You said you'd grab both before Thursday.

Wait — I never told it about the drawer...

"Documents are in my desk drawer" · extracted from a voice memo, March 12

What time is Maya's soccer game on Saturday?

3:00 PM at Lincoln Fields. Dave is dropping her off. She needs her new cleats — you picked them up from Dick's Sporting Goods yesterday.

I forgot I even told you about the cleats 😅

You mentioned it right after pickup — "She's growing so fast, needed half a size up" · connected to her soccer schedule

What did Dr. Chen say about my blood test?

Results were normal across the board. Follow-up is next Tuesday at 10:00 AM at the clinic on Pine St. You also mentioned feeling less anxious since starting the morning walk routine.

That walk thing was just casual chat...

Everything you say is memory. Morning walks started April 2 · connected to your mood log and Dr. Chen's appointment

What's the deal with my sourdough starter?

"Bubbles" took 2 weeks to mature. Feed every 12 hours at 75°F. You named it after the first bubble you saw — and today you're baking your first loaf!

I can't believe you remembered the name 😂

The Problem

Every AI chat starts from zero.

mylifebrain starts from everything you've already said.

Every other AI chat

Session 1:"Started learning Japanese on Duolingo, finished hiragana in two weeks!"

Session 2

AI replies:"I don't have info about that. You haven't mentioned learning Japanese."

Forgotten. Every. Single. Context.

With mylifebrain

Session 1:"Started learning Japanese on Duolingo, finished hiragana in two weeks!"

Session 2

mylifebrain replies:"You finished hiragana in 2 weeks on Duolingo. You said you'd start katakana next. Keep it up!"

It remembered. Because it never forgets.

FAQ

Questions? We have answers.

Is my data really private?

Yes. Your data never touches our servers. It lives in your own Supabase database, on your own Vercel deployment. We have zero access.

How is this different from ChatGPT or Claude?

Those are stateless chatbots. mylifebrain extracts entities, builds a knowledge graph, and remembers everything permanently in a searchable, queryable structure.

What does "self-hosted" mean?

You deploy mylifebrain on your own Supabase and Vercel accounts. You own the infrastructure and the data. We provide the software.

How long does setup take?

About 10 minutes. You need 4 free accounts: Supabase, Groq, Gemini, and Vercel. See visual step-by-step guide →

What happens to my data if I stop paying?

There are no subscriptions. Your data stays in your Supabase database forever. You can export it anytime as structured JSON.
