Hey everyone,

I wanted to share a small experimental project I built with Codex / Prism: Inside.

It’s a portable Windows app that turns a local LLM chat into a cinematic black-hole interface instead of a normal chat window. Messages fall into the center, responses emerge from it, and the whole thing feels more like a spatial / audiovisual medium than a traditional textbox UI.

It works with local / OpenAI-compatible backends such as LM Studio and Ollama-style setups. It does not bundle any model — you bring your own local LLM and point Inside at your backend.

A few notes:

* Portable Windows build
* Friendly freeware license
* No bundled model included
* Designed mainly for LM Studio / local OpenAI-compatible servers
* Experimental cinematic interface, not a productivity-first chat client
* Independent project, not an official OpenAI product

Created by Sebastian Kostrzewa in collaboration with Codex / Prism, my AI coding and design companion for this project. Prism helped design, code, debug, package, polish the interface, and shape the visual language of Inside.

The goal was simple: what if talking to a local model didn’t have to look like every other chat window?

If you try it, I’d love feedback — especially around local backend compatibility, UI feel, and whether this kind of “spatial chat” interface is something people would actually enjoy using.

Codex helped me build Inside — a free black-hole interface that turns local LLM chat into a spatial experience
