## Choose when

### Choose AirSim if…

- AirSim is primarily C++; PhotoSketch is Python.
- Tags unique to AirSim: autonomous-quadcoptor, airsim, artificial-intelligence, cross-platform.
- Also covers AI Agents.

### Choose PhotoSketch if…

- PhotoSketch is primarily Python; AirSim is C++.
- Tags unique to PhotoSketch: sketch, python, graphics.
- Leaner open-issue backlog (5).

## When NOT to use AirSim

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.

## When NOT to use PhotoSketch

- Last GitHub push was 1159 days ago (dormant maintenance, May 10, 2023). Validate activity before betting a new project on PhotoSketch.
