I'm Youssef, founder of mokka, based in Siegen, Germany.
I build tools to test AI systems, make their decisions inspectable, and keep data under your control.

Open-source projects with code, examples, and a way to try them.
Replay calls or probe a live WebSocket agent. Gate on transcription, latency, interruptions, and task outcomes. Python · CLI + library · Apache-2.0 |
A local research notebook with versioned sources, cited claims, and evidence you can trace back to the original passage. Windows desktop · Local storage and models · MIT |
|
Local support-ticket routing with urgency signals and human handoff. Includes a fine-tuned BANKING77 model and reproducible evaluations. Python · Local decision model · Apache-2.0 Code · Try the app · Model · Results |
A German-speaking voice agent that qualifies heating-service leads, with a dashboard and a two-agent call simulator. Next.js · ElevenLabs · PostgreSQL · MIT |
Small Python packages for routing, retrieval, and evaluation. The laya tools use a local decision model; the Clef tools integrate with Cloudflare's decision models.
| Task | Local · laya | Cloudflare · Clef |
|---|---|---|
| Evaluate — confidence audits & CI gates | laya-evals · PyPI | clef-evals · PyPI |
| Route — choose an LLM per request | laya-router · PyPI | clef-router · PyPI |
| Compact — fit evidence to a token budget | laya-compactor · PyPI | clef-compactor · PyPI |
laya-phishield applies the same approach to phishing detection: local semantic signals, deterministic email checks, and an explainable risk score. PyPI
These are independent tools built on laya and Cloudflare Clef. Each repository documents its setup, benchmarks, and current limitations.
Your extractor reads the same invoice in three locales. Your vision API gets the same pixels. Measure both — offline-first regression kits with deterministic CI gates.
- locale-invoice-check — EN/DE/ES invoice extraction, deterministic CI gates · PyPI
- vision-input-check — pixel-identical vs lossy image variants, variance-aware gates · PyPI
