Architecture Comparison
Cloud-Only Bots vs. SautiMesh Runtime
See why an offline-first cascade succeeds where internet-dependent AI wrappers drop calls or stall wallets.
| Field Requirement | Cloud-Only Wrapper | SautiMesh v0.1.0 | Guarantee |
|---|---|---|---|
| Zero Connectivity / 2G | Fails or times out | Local rules resolve immediately | 0 ms · 0 Bytes |
| Mixed Language Speech | Drops rural & tonal terms | Word-level 8-language CSI tagging | 8 Lexicons Live |
| Mobile Money PINs & Phones | Uploads raw transcripts | Redacted in memory prior to routing | Local PII Scrub |
| SMS & USSD Delivery | Truncates multibyte text | Exact 160-char GSM-7 / 70-char UCS-2 packing | 182B USSD Safe |
| Power Dropouts | Lost requests & duplicate sends | Idempotent SQLite WAL store-and-forward | Zero Split-Brain |

questions
How does SautiMesh handle intermittent connectivity and power dropouts?
Every turn executes offline-first playbooks using SQLite WAL persistence and an idempotent store-and-forward outbox queue, syncing safely without split-brain corruption when cellular service returns.
Which African and global languages does SautiMesh support?
SautiMesh ships built-in lexicons and code-switch analyzers for Swahili, Luganda, Yoruba, Hausa, French, English, Nigerian Pidgin, and Runyankole, plus adapters for Sunbird Sunflower v2, whisper.cpp, MMS, and Piper ONNX.
How does SautiMesh prevent runaway cloud API costs?
Its 3-stage cascade resolves routine turns locally in 0 ms, supports local SLMs via Ollama or llama.cpp, redacts phone numbers and PINs before cloud calls, and enforces daily local-currency spend limits.
