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.

Nimitai is an AI meeting-intelligence and conversation-analytics platform built specifically for B2B sales teams at startups and growth-stage companies. It is structured around specialized functions: a research step that pulls prospect intelligence before a call, a preparation step that generates pre-call briefings with talking points and deal context, and a live copilot that delivers real-time coaching during the meeting. Nimitai captures calls through a lightweight Chrome extension that works with Zoom, Google Meet, and Microsoft Teams without requiring a separate bot to join the call. During a live conversation it records and analyzes audio and engagement signals, surfaces coaching cues, flags unaddressed objections, detects shifts in buyer interest, and highlights deal-risk signals so reps can adjust in the moment. After the call it generates structured scorecards and call summaries and can sync them to CRMs such as Salesforce, HubSpot, and Pipedrive, reducing manual data entry. It is aimed at sales organizations that want both real-time selling assistance and post-call analytics in a single tool, positioned as an option for smaller revenue teams. The platform is operating and accepting B2B sales teams. Pricing varies by plan. Check the official website for current pricing.
