Smfs or Presto Voice: which should you choose?
| Dimension | Smfs | Presto Voice |
|---|---|---|
| Pricing | Freemium (free tier + paid) | Contact sales (custom) |
| Primary Use | Memory as a POSIX filesystem for AI agents | Drive-thru voice AI for QSR chains |
| Key Feature | Semantic grep + POSIX mount | Automated order taking with upselling |
| Integration | None listed (filesystem-based) | POS, headset systems, ElevenLabs |
| Best For | Developers building AI agents | QSR chain operators |
| Target User | Technical developers/researchers | Non-technical restaurant managers |
Presto Voice and Smfs serve completely different needs. Presto Voice is a drive-thru voice AI for QSR chains, focused on automating orders and boosting revenue via upselling, with recent adoption by Dairy Queen. Smfs is a developer tool that mounts AI agent memory as a filesystem, enabling semantic search via standard bash commands. Choose Presto if you run a multi-location QSR; choose Smfs if you build autonomous agents and want to replace vector databases with POSIX calls.
Smfs mounts a Supermemory container as a real POSIX directory on macOS and Linux, so ls, cat, and grep become memory operations.
