On-device RAG for pilots + agentic system for ground operations.

The client is Overwatch AI, a startup building AI assistants for major airlines. Their pilot project — the largest European airline (NDA).

on-device iOS / iPad offline RAG aviation agentic systems hiring help
§ a Context What's at stake

An AI assistant working offline mid-flight — and a heavier agentic system for the airport.

In flight, the pilot has an iPad with EFB documentation in hand. Often without internet (aircraft, remote locations). The documentation — flight manuals, checklists, operating procedures — runs hundreds and thousands of pages.

On the ground, at the airport, the picture is different: internet access and large compute budgets, but an even larger document volume and more complex ground-staff workflows.

The task — two distinct perimeters of one product.

  • a.In the air: fully on-device, no network fallback.
  • b.On the ground: a full agent with multi-step reasoning over thousand-page manuals.
  • c.Capability handover: the client's team should evolve the system on its own.
§ b What we did Under the hood

Pilot copilot on iPad, offline · agentic system architecture for ground operations · hiring help.

Pilot copilot. Fully on-device inference and retrieval. No cloud, no network fallback in flight. Distilled-model selection and tuning under the iPad's hardware constraints. The index lives on the device and updates without a network.

System-evolution pipeline. We left the client not just the system, but the process for evolving it: how to add documents, update the model, evaluate quality, iterate.

Ground operations: agentic system. A full agent doing multi-step reasoning over thousand-page manuals — beyond the classical RAG pipeline of «query → embeddings → answer».

Hiring help. We took part in hiring two in-house AI engineers for the client: helped with role design, technical interviews, onboarding. Goal — the company should be able to evolve the product without us.

§ c Result What came out
Result
The company went through Techstars, won Startup of the Year at Aviation Festival Asia, successfully completed a pilot project with the largest European airline (NDA), and brought two AI engineers in-house with our help in hiring.
§ d Where it got tricky Under the hood
  • a.On-device LLM inference on iPad: distilled model + hardware-aware optimization.
  • b.On-device retrieval: index lives on the device and updates without a network.
  • c.Multi-step reasoning over thousand-page flight manuals.
  • d.Two perimeters of one product: offline in flight, online on the ground.
  • e.A pipeline where the client adds documents and updates quality on their own.
  • f.Handoff that includes hiring in-house AI engineers on the client side.
