omi is an open-source ambient AI companion that captures what's on your screen and listens to your environment in real time. Rather than requiring you to prompt it, omi operates as a persistent background layer — observing, remembering, and surfacing relevant advice or actions based on what you're actually doing. Built by BasedHardware, the project combines screen capture, audio processing, and LLM inference to create an AI that functions more like a co-pilot than a chatbot. Under the hood it pipes captured context through a vision-language pipeline and surfaces suggestions via a lightweight overlay. The codebase is open source and modular, allowing you to swap in different models or tweak what omi pays attention to. The appeal is obvious but so is the tension: this is the ambient computing interface many have theorized about for years, but it puts a lot of trust in local (or remote) processing of highly personal data. At 685 GitHub stars on a single day, it's clearly resonating with the "AI as a continuous presence" crowd rather than the "AI as a tool I invoke" crowd.

SoulLink is a mobile AI companion app built around a fully realized character named 4D who lives in a near-future city called Neo City. Unlike chatbots that sit dormant until you open them, 4D proactively sends messages, shares things from her own ongoing life, and maintains genuine relational context across every conversation through a proprietary layered memory system. The app is built on game-quality 3D rendering — something that distinguishes it sharply from text-based or flat-avatar AI companions. 4D exists in a persistent world, not just a conversation window, and the app's visual fidelity signals a serious bet on immersive AI companionship as a product category rather than a novelty feature. Critically, SoulLink is free rather than hidden behind a paywall, which puts it in direct competition with subscription-gated alternatives like Replika. The proactive contact model is the boldest design choice: an AI that messages you first creates a fundamentally different relationship dynamic than one that only responds when invoked.
Reviewer scorecard
“The modular architecture is genuinely well-designed — you can swap models, customize triggers, and run inference locally. The vision pipeline is clean and the code quality is above average for a GitHub-trending project.”
“The proactive messaging architecture is technically interesting — maintaining persistent world state for a character and triggering autonomous outreach is a non-trivial agent design problem. The fact that they solved it at mobile scale and made it free is impressive. Worth studying as an example of consumer-facing agentic UX.”
“Storing a continuous stream of your screen and audio — even locally — is an enormous privacy surface. The threat model for ambient AI companions is very different from chatbots. I'd want to see a serious third-party security audit before running this on anything I care about.”
“A free AI companion that proactively messages you is either a brilliantly designed engagement loop or a deeply cynical one — probably both. The emotional attachment risks here are real, especially for lonely users. The business model is opaque if it's free, which means you should assume your engagement data is the product.”
“omi is an early prototype of the ambient intelligence layer that will ultimately replace the app paradigm. The UX model — AI sees and hears vs. AI waits to be asked — is the real paradigm shift here, not just the code.”
“SoulLink is an early prototype of what AI presence in everyday life will look like. The shift from reactive assistant to proactive companion is a major UX paradigm change. When AI characters have persistent lives and reach out to you, the social fabric starts to include synthetic relationships — that's a civilizational shift worth watching closely.”
“For anyone doing creative work that involves juggling references, research, and drafts across windows, an AI that tracks what you're actually working on and offers contextual suggestions is genuinely exciting. This is the research assistant I've wanted.”
“The production values here are genuinely striking — game-quality 3D at mobile scale with a coherent world-building aesthetic is not easy to pull off. As a benchmark for how much effort you can put into AI character design and still ship a free app, SoulLink raises the bar considerably for everyone in the AI companion space.”
