Honest comparison
Hey Lunem vs ChatGPT
ChatGPT is an excellent general chat product. Hey Lunem is a Windows desktop learning companion: always a shortcut away, built to teach on your screen, and local-first with your data.
| Hey Lunem | ChatGPT (typical web/app) | |
|---|---|---|
| Form factor | Native Windows desktop app | Browser or phone chat app |
| Summoning | Global shortcut Ctrl+Alt+Space | Open a tab or app |
| Teaching style | Live whiteboard + on-screen pointers | Primarily text (and some canvas tools) |
| Screen context | Explicit, per-request, with privacy modes | Depends on product; not a Windows overlay tutor |
| Memory default | Local on your Windows profile | Account-cloud memory features |
| Models | Lunem Cloud, your keys, or local Ollama | OpenAI-hosted models |
| Price to start | Free Windows download | Free tier + paid plans |
When to choose Hey Lunem
- You study or work on a Windows PC and want help without leaving your flow
- You want explanations drawn and pointed at, not only written
- You care that memories and keys stay on the device by default
- You may want a fully local Ollama path later
When ChatGPT may be enough
- You mainly need general Q&A in a browser
- You are not on Windows, or you do not need desktop overlays
- You already live inside the ChatGPT ecosystem day to day
Hey Lunem can also call cloud models you choose — including Anthropic, OpenAI, Gemini, or Azure — so it is complementary, not anti-model. The difference is the desktop teaching shell.
