Enterprise AI customer research platform that recruits participants, runs AI-moderated interviews, and delivers executive-ready insight reports.
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.

Listen Labs is an AI-first customer research platform that automates the qualitative research workflow end to end, from study design and participant recruitment through AI-moderated interviews to insight delivery. Its AI interviewer conducts personalized, in-depth conversations with each participant, asking follow-up questions and understanding context without a human moderator, and the platform supports video, audio, and text formats in 100-plus languages with automatic translation and transcription. Studies can incorporate stimuli such as videos, images, and Figma prototypes, and recruitment draws on a global network of tens of millions of qualified participants, with the option to integrate existing recruitment providers or bring your own audience. Once interviews complete, Listen Labs automatically packages results into executive-ready outputs, surfacing key themes and takeaways, generating personas, and producing highlight reels and slide decks, with turnaround measured in hours rather than the weeks typical of traditional research. The company is venture-backed and reports use by large consumer and technology brands, positioning the platform for enterprises looking to replace or supplement surveys and traditional market research with scalable AI-led interviews. Pricing varies by plan. Check the official website for current pricing.
