Celeste AI is a Brazilian voice AI and transcription platform that specializes in Portuguese, particularly Brazilian Portuguese, while also processing audio in additional languages such as English, Spanish, German, Italian, and French. Originally known for automated audio-to-text transcription that the company positions as far more efficient than manual transcription, Celeste AI has expanded into a broader suite that includes a Meeting Assistant (Assistente de Reunião) and AI Notes (Notas de IA), alongside transcription and quality-monitoring offerings. The platform uses machine learning speech models tuned for Portuguese and is offered both as an on-demand service and via an API, so users and businesses can transcribe content as needed. Its on-demand model lets customers pay only for the hours they actually use by purchasing credits, with flexible subscription plans available for those who have recurring transcription needs. As a Brazilian company connected to local institutions such as FGV Ventures and the São José dos Campos technology park, Celeste AI is oriented toward the Brazilian market and Portuguese-language workflows, and it reports a growing user base. The service is currently operating, with a functioning login, demo requests, and support, and is suited to professionals and companies that need accurate Portuguese transcription and meeting documentation. Pricing varies by plan. Check the official website for current pricing.

Zenarate is an AI simulation-training and conversation-analytics platform for contact centers, and its Performance Analyzer (formerly Call Analyzer) is the module that turns live customer calls into structured quality and coaching data. The AI engine automatically transcribes each interaction, redacts sensitive information, and scores calls against a client's defined call model and skill expectations, processing up to 100% of calls rather than a small sampled subset. Analysis runs nightly so leaders have results the next day, with automated scorecards, sentiment analysis, topic and trend reporting, and next-action coaching recommendations. Managers can drill into specific conversation moments, listen to the audio, and add commentary directly from the scorecard. Because it sits inside Zenarate's AI Coach platform, identified gaps can be turned into personalized roleplay simulations and coaching plans. It is built for QA managers, training leaders, and contact-center operations across industries such as financial services, healthcare, insurance, telecom, retail, and travel, and supports multiple languages and global deployments.
