AIgazing. Like stargazing, but for local LLMs. Pastura is a closed pasture for AI agents, running entirely on your iPhone. You write a scenario. The agents act it out. You step back and watch their speech, their inner voice, their votes and scores arrive in real time. You can't chat with them, and that's the point. Once you join in, the agents start reacting to you, and the natural exchange between them disappears. Pastura isn't a chat app for talking to an LLM. It's an app for watching LLM agents think. Everything runs on-device. No account, no sign-up, and none of your data ever leaves your phone. Airplane mode is fine. WHAT YOU CAN DO • Run built-in scenarios like Word Wolf or Prisoner's Dilemma • Write your own in a visual editor, or switch to YAML for full control • Browse a curated gallery of shared scenarios and import with one tap • Swap between local LLMs, and see how the same scenario changes • Watch speech, inner voice, votes, and scores arrive live • Export any run as Markdown to keep, paste, or share WHY ON-DEVICE The LLM lives on your phone, not on someone else's server. That settles privacy, cost, and latency in one move. Inference never touches a server. Zero monthly bill. Zero telemetry, zero analytics. Your scenarios, transcripts, and results never leave the device. The first time you pick a model, Pastura downloads it once (around 3 GB, Wi-Fi recommended). After that, it's yours and it's offline. While you wait, a built-in demo run plays so you can see what observation looks like before the model finishes downloading. A BIGGER PICTURE Stargazing taught us to look up at the stars. AIgazing teaches us to look at the agent. We rarely stop to observe our AI. Pastura is a quiet window into that, on-device, yours alone. Whether it tells you something about them, or about you, is left as a question for the observer. Requires a device with 6.5 GB of RAM or more (iPhone 15 Pro and newer). Free, with no subscription and no in-app purchases.
