Krisp
Krisp is best known for AI noise cancellation that strips background sound from any call in real time, and has expanded into an AI meeting assistant with transcription, notes, and summaries. It works as a desktop app that sits between your mic and any conferencing tool, plus an embeddable Voice SDK for developers building voice products. Consumer plans run around $8-15/mo (billed annually); the old perpetual free tier appears to have narrowed to a trial, and Voice SDK pricing is contact-sales. Its noise-cancellation quality is its real moat -- it's a meeting and utility app, not a transcription API like AssemblyAI or Deepgram.
Rime
Developer-focused text-to-speech API built for real-time voice agents and conversational AI. Prioritizes ultra-low latency, emotional expressiveness, and enterprise compliance including HIPAA. Integrates natively with Together AI and popular agent frameworks. Built for teams shipping production voice experiences, not consumer audio projects.
Krisp edges Rime on aggregate — 73 vs 69.
Best-in-class AI noise cancellation that grew into a meeting assistant -- a polished utility app, not a transcription API, with a free tier that's quietly shrunk. Rime still wins for buyers who prioritise ultra-low latency (<700ms). Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
