Smallest.ai - Pros & Cons

Pros

  • ✓Low-latency positioning targets the central constraint in live voice interactions
  • ✓Combines speech generation with conversational-agent workflows
  • ✓Developer APIs allow integration into existing call routing

Cons

  • ✗Per-minute prices, included voices, concurrency, and telephony charges could not be verified
  • ✗Call automation requires consent, disclosure, recording, and do-not-call controls
  • ✗Accent quality, interruptions, and noisy-line performance need real-call testing

Krisp - Pros & Cons

Pros

  • ✓Bi-directional noise cancellation is the strongest in the category — works for both sides of the call
  • ✓No-bot AI notes — privacy and discretion advantage over Fireflies/Otter
  • ✓OS-level install means one tool covers Zoom, Meet, Teams, Slack, WhatsApp, dialers and recorders
  • ✓Accent AI is genuinely useful for global support teams and is rare in this category

Cons

  • ✗Real-time noise model uses noticeable CPU on older laptops
  • ✗Free tier caps AI features at 60 min/day — heavy-call days will hit the limit
  • ✗Speaker diarization on transcripts is weaker than bot-based tools that have meeting metadata
  • ✗No MCP support — transcripts and summaries are not exposed as tools for agents
