## Misul Research Suite

Misul is an independent AI research lab founded by Deyan Todorov. It designs neural architectures from first principles rather than scaling standard transformers.

- [Laplace](https://github.com/MisulOrg/Laplace): Apple Silicon inference engine that compiles declared model operations and tensor storage into native Metal execution. Compatible dense models run today, including mixed stored precisions and tied weights. Recurrent and routed expert execution in the shared compiler is still being built. Active alpha.
- [Interlace](https://misul.org/Interlace): Shared architecture for language and iterative computation. Combines content-selected attention, gated delta memory, and bounded rational features in a backbone that reuses its layers across computation steps. Paper: https://github.com/MisulOrg/Interlace/blob/main/paper/interlace.pdf. Source repository: https://github.com/MisulOrg/Interlace.
- [Monodratic](https://misul.org/monodratic/): Content-routed causal sparse attention sequence mixer with post-RoPE routing, bounded causal postings, and exact softmax. Source repository: https://github.com/MisulOrg/Monodratic.

## Independent Projects

- [PhoneCode](https://dttdrv.xyz/phonecode.html): Native Android coding agent that edits local workspaces and talks to chosen model providers from the device, with no proxy and no telemetry.
- [optiSYS](https://dttdrv.xyz/optisys.html): Native Windows system optimizer tuning system responsiveness, network stack buffers, and process scheduling without bloat.
- [dzipobel.wiki](https://dzipobel.wiki): Digital literature and grammar educational repository for Bulgarian state high school examinations.
- [SchoolMap](https://schoolmap.pages.dev): Interactive classroom mapping application for geographic curriculum visualization.
