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.
Mount Supermemory as a real filesystem—ls, cat, and grep become semantic memory operations.
