Inboxed vs. Spark
Spark is a polished email client. But it stores your emails on Readdle's servers to power its features. Inboxed gives you the polish without the privacy trade-off.
| Feature | Spark | Inboxed |
|---|---|---|
| AI Processing | Cloud-based (OpenAI) | Local LLM (Apple MLX) |
| Privacy | Emails stored on Readdle servers | 100% On-Device |
| Cost | $59/year (Premium) | Free (Pro: $1 lifetime) |
| AI Smart Reply | Cloud AI (GPT-4) | Local LLM on Metal GPU |
| Data Ownership | Readdle retains copies | Your Mac only |
Same polish. Zero cloud dependency.
Spark's AI features are impressive — but they require your emails to be stored on Readdle's servers and processed through OpenAI's API.
Inboxed delivers the same smart features using models that run entirely on your Mac. No server storage, no API calls, no data sharing.
