Pothos

Pothos is a multi–user computational entity inspired by the Greek god of longing and yearning. It isn’t generative AI and uses no ML/RL. Instead, it’s built on a Case-Based Reasoning behavior model with softmax-driven mood drift and genuine pink-noise randomness. The result is a creature that reacts with passive nihilism: sometimes cooperative, sometimes hesitant, sometimes refusing outright. It's a very small-scale AI alignment experiment too, that's disguised as a digital tamagotchi.

Players share a single global Pothos.
Everyone draws from the same limited resources, and everyone affects its mood.

Ask it to do something, and Pothos may answer with:

• “yeah”

• “no”

• “idk maybe”

• “why.”

• or just “…”

Its depression, energy, and willingness are all tied to communal behavior and in-world resources. It’s essentially an MMO-style tamagotchi crossed with a tragedy-of-the-commons experiment.

This is an MVP and a portfolio research piece in game systems design — not a traditional game. It uses:

• Unity WebGL

• Supabase for global state

• Custom backend services

• Discord OAuth

• A browser extension + Unity JSLib bridge

• CBR-style decision logic with mood-weighted bark selection

It may not stay online for long due to backend GPU requirements, but the experiment is here for anyone curious about computational mood, shared agency, and the behavior of digital creatures under scarcity.

OH. I also have a python sql injection that pings the unity clients, so I can send a request to give Pothos an investment (debt based), grant (requires energy) or donation (might decline) and it will add to the SQL cash and Pothos will accept or reject. Server authoritative too!

...so Pothos may take a moment to think!

Edit: CBR is the wrong descriptor and term, it's actually an utility-based agent / stochastic state machine with conditional template selection.
