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.
Best suited for
Copilot in Microsoft Teams is the AI meeting assistant built into Microsoft 365 Copilot. During or after a Teams meeting it summarizes key discussion points (including who spoke and what they said), suggests action items, and answers questions by reasoning over the conversation and meeting chat. It works in real time via the Copilot button and is also available afterward through the meeting chat and Recap tab. Transcription does not have to be running just to turn Copilot on during a meeting, but live transcription must be enabled to prompt Copilot about what was said and to access its conversation history after the meeting ends; recording itself is not required. Longer responses can be opened in Word, and table-style output in Excel. Copilot is sold as a paid add-on that requires a qualifying Microsoft 365 or Office 365 subscription, and it extends beyond Teams across Word, Excel, Outlook, and other Microsoft 365 apps. A no-cost Microsoft 365 Copilot Chat tier is included for eligible subscribers but excludes the full work-grounded Teams meeting Copilot experience.
