Comparison
Local-first vs cloud PDF tool model
A practical capability matrix based on workflow behavior: privacy, offline support, queue depth, and AI grounding with citations.
| Capability | OnDevicePDF (local-first) | Typical cloud tool |
|---|---|---|
| Document privacy | Most tools process on-device with no upload. | Files are uploaded for processing. |
| Offline capability | Most tools continue after first load. | Network required for processing. |
| Batch workflows | Desktop queue supports sequential runs with pause/resume. | Queue behavior depends on service limits. |
| Local AI / QA | Hybrid local retrieval with cited answers and source jumps. | AI features typically run on remote inference. |
| Latency profile | Immediate local execution, no upload roundtrip for most tools. | Upload + queue + processing + download cycle. |
| Data control | Sessions are local, with explicit clear controls. | Retention and deletion follow provider policy. |
Note: advanced editor operations may use secure temporary backend processing when browser-only execution cannot reliably produce permanent output.
