Why Local Intelligence Changes Everything

Cloud APIs process your audio. Signal Loom processes your audio on Apple Silicon โ€” privately, predictably, and at hardware cost. Here's the real difference.

Who This Is For
๐Ÿค–
AI Agent Builders
Building agents that need structured, timestamped, machine-readable audio intelligence โ€” not just human-readable transcripts.
๐ŸŽ
M-Series Mac Owners
Your Apple Silicon hardware runs MLX Whisper faster than any cloud API โ€” and your data never leaves your machine.
๐Ÿข
Privacy-First Enterprises
Healthcare, legal, financial โ€” industries where audio data cannot go to third-party clouds. It stays on your infrastructure.

MLX on Apple Silicon
Cost & Economics
Per-minute API cost $0.006โ€“$0.024 / min
Scales with usage. No ceiling.		 Hardware cost only
No per-minute API billing. Predictable.
Cost at scale (1M min/mo) $6,000โ€“$24,000 / month ~$0.03 / kWh
M4 Pro ~40W at full load = ~$10โ€“15/month
Infrastructure cost predictability Variable โ€” usage-based Fixed โ€” one-time hardware
Privacy & Data Sovereignty
Audio data sent to third-party cloud YES โ€” every file NO โ€” processed locally
HIPAA / data residency compliance Requires BAA + configuration Native โ€” data never leaves
Enterprise audit trail Cloud provider logs only Full self-hosted control
Customer data stays private Governed by cloud ToS 100% under your control
Speed & Latency
Network round-trip latency 50โ€“500ms per request
Depends on file size + connection		 Zero network latency
Direct hardware access
M4 Pro processing speed Depends on cloud region ~4,000ร— realtime audio
20s audio in ~4 secondsๅฎžๆต‹
Throughput at scale Rate-limited by plan Unlimited โ€” run 24/7
Output & Intelligence
Word-level timestamps Available but inconsistent Native โ€” every word
Multi-format output (JSON + SRT + VTT + TXT) JSON only โ€” formats extra All four formats โ€” one pass
Structured schema for AI agents Raw transcript โ€” post-processing needed Schema-bound output โ€” machine-ready
Signal Loom Schema (SLS) Not available Signal Loom owns this
Infrastructure
Runs on your hardware No โ€” cloud only Yes โ€” Mac Studio, Mac mini, MacBook Pro
Works offline / air-gapped Requires internet Yes โ€” fully offline
API + SDK for developers Yes Yes โ€” REST API + Python SDK
Webhook delivery Yes Yes
Usage-based billing (Stripe) Yes Yes โ€” tiered plans
For AI Agents: This Is the Missing Layer
AI agents can reason remarkably well โ€” but they're blind to the majority of enterprise knowledge, because it lives in audio and video they cannot structurally interpret. Signal Loom converts raw media into structured, timestamped, machine-readable intelligence โ€” the input format AI agents actually need. Not a transcript. Not a summary. A knowledge object with provenance.

No spam. No pitch decks. Just access.
The honest answer.
Cloud APIs are fine for prototypes. When audio data, cost at scale, privacy compliance, and infrastructure control matter โ€” local intelligence on Apple Silicon wins on every dimension that counts.

Signal Loom AI runs Whisper on your Mac hardware. You own the infrastructure. Your data never leaves.
