Cresta is an enterprise customer-experience AI platform that unifies human and AI agents across voice and digital channels. It captures conversations through integrations with major contact-center systems such as Genesys, NICE, Salesforce, Twilio, and Amazon Connect, then analyzes those interactions at scale to surface behavioral insights and deliver real-time guidance. Its Agent Assist listens to live conversations and provides agents with in-the-moment suggestions, knowledge, and next-best actions, while a Knowledge Agent proactively surfaces context-aware answers without manual prompting. Cresta's conversation intelligence analyzes 100% of interactions to identify the behaviors that drive outcomes, and its automated quality management scores conversations across the board so supervisors gain visibility without manual sampling. The platform also offers autonomous AI agents that can resolve customer conversations end to end, plus an Agent Operations Center that gives supervisors real-time visibility and intervention tools across both human and AI-led conversations. Cresta is built for large enterprise contact centers in industries such as financial services, travel and hospitality, telecommunications, insurance, and healthcare that need real-time assistance, coaching, and analytics at scale. Pricing varies by plan. Check the official website for current pricing.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
