Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and HeyMarvin when product teams clustering interview feedback into shareable themes matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

HeyMarvin (Marvin) is an AI-native customer insights platform aimed at user-research and product teams, with the research interview as its central meeting type. During live user-research calls it records sessions, transcribes them automatically, and lets researchers capture time-stamped notes and highlights, including collaborative live note-taking with teammates. After the session, its AI workflows distill feedback into themes and patterns, and an Ask AI feature lets teams query their data and get answers with citations back to the source clips. Everything feeds a centralized, searchable research repository that brings qualitative and quantitative inputs together from many sources, so insights are not scattered across documents and recordings. The platform also offers AI-moderated interviews in multiple languages, video clips and curated playlists for sharing findings, and integrations with tools used to distribute insights. It includes privacy and security features such as PII redaction and enterprise compliance. For a meeting-tools directory, its relevance is the combination of interview capture, AI notetaking, and a repository tuned for analyzing user-research conversations rather than general meetings. Pricing varies by plan. Check the official website for current pricing.
