Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and Strella when b2b and b2c qualitative studies with built-in recruitment 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.

Strella is an AI-powered customer research platform designed to run in-depth interviews and generate actionable insights in hours rather than weeks. Teams create a study in minutes using AI-generated, unbiased discussion guides that any team member can refine and launch, and they can either lead interviews themselves or hand moderation to Strella's AI moderator for faster results. During AI-moderated sessions, the platform conducts the conversation and adapts questions in real time based on each participant's responses, asking thoughtful follow-up questions to explore topics more deeply. Strella handles study logistics including recruitment, incentives, and scheduling, and offers a choice between interviewing customers a team already knows or recruiting from a panel of millions of global participants with targeting across professional, demographic, and behavioral segments; it supports research in dozens of languages for both B2B and B2C studies. On the analysis side, the platform synthesizes findings in real time, identifies themes across participants and segments, and lets researchers chat with their research to generate video highlight reels and pull insights at multiple levels, from an individual participant up to broader strategic patterns. The company is venture-backed and reports use by recognized consumer brands. Pricing varies by plan. Check the official website for current pricing.
