AI engineering shaped by how people learn and work

DLYog Lab is an independent AI research, development, and consulting company. We build practical systems, test them honestly, and contribute useful work back to the community.

Two educators, one applied AI lab

Our education backgrounds keep the work grounded in real users, clear explanations, thoughtful evaluation, and tools that help people—not technology for its own sake.

Our commercial focus

Precision Personal Software for small businesses

We are a small California business serving other small businesses. Through Let Us Vibe for You, we build software around one defined business outcome, agree the acceptance criteria, scope and price in writing, and do not introduce unexpected changes. We also conduct applied AI research. AI4Echolalia™, our TED AI San Francisco Hackathon award-winning special-needs education platform, remains our flagship application for licensing.
