Day 3 — Letta in Action: When Stateful Memory Becomes Real

Letta demo with the editorial team: stateful memory, custom interface, and the moment the project takes shape. Réfugiés.info build in public.

1. What Happened Today

This morning, I had a breakthrough moment. I did a big Letta demo with Julie and, for the first time, I felt the project take shape right before her eyes.
We explored memory blocks, watched the AI rewrite its own memory in real-time… and seeing her expression at that exact moment was a real rush.
We also laid the groundwork for the custom interface for the editorial team: a panel on the left (content, metadata, localization), a chat on the right, and workflows finally adapted to their reality.
She left reassured, motivated, ready to tackle wireframes. And that changes everything.

2. Today's Challenge, Friction, or Surprise

The most surprising moment was when Julie saw Letta modify its memory in real-time in the ADE.
A mix of fascination, "wow", and a little vertigo.
And that's when I thought: okay, we need to frame this carefully.
This power opens incredible doors, but it needs to be understood and tamed by the whole team.

3. The Technical Point

That moment made me realize we need to onboard the whole team on how Letta manages memory: what's contextual, what's archived, what's modifiable or locked.
The features that come from this are so cool, but they require a solid framework.

That afternoon, I aligned all this with Luis on the ingestion side:

On the storage side: Markdown for content, structured JSONB for metadata. Clean and robust.

My tech to-do for the coming days:

Real work, finally.

4. The Human Moment

When I saw Julie's reaction, I felt something very simple:
all my weekends geeking out on this tool weren't for nothing.
It's like someone else finally saw what I'd been seeing for weeks.
And that feels amazing.
The project is starting to exist in other people's heads — and that's worth all the determination in the world.

See you tomorrow.
