Soul & Memory Lab

An AI has no brain inside β€” its personality and its memories are just text files it reads when it wakes up.

Meet Pip, a tiny AI agent. 🐣 Two plain text files make it who it is: SOUL.md (its personality) and USER.md (its memory about you). Edit them below β€” then hit Restart agent ↻ to watch Pip wake up changed. πŸ‘‡

SOUL.md β€” Pip's personality file
Tap a personality to write into SOUL.md
✎ SOUL.md edited β€” restart to load the new personality.
USER.md β€” Pip's memory notebook about you
Tell Pip a fact β€” it gets written to USER.md
πŸ“₯ Receive β†’ ✍️ Record β†’ 🧠 Recall
🧠 Amnesia mode β€” delete USER.md (Pip forgets everything)
✎ USER.md changed β€” restart to update what Pip remembers.
● needs restart to load the files

Files are only read at startup. Change a file, and nothing happens until Pip restarts and re-reads it.

🐣 Pip · just woke up
Hi… I just turned on. I haven't read my files yet. Edit SOUL.md or USER.md, then press Restart agent ↻ so I can load them. πŸ’€
Here's the big idea. An AI has no biological memory. Its personality lives in SOUL.md and its memories about you live in USER.md β€” both are plain text files it loads when it starts up. That's why editing a file does nothing until you restart (the file is only read at startup), and why deleting USER.md means it forgets you completely. Memory isn't magic β€” it's just Receive β†’ Record β†’ Recall: hear a fact, write it to a file, read it back next time. πŸ“₯✍️πŸ§
