Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and Exec when rehearsing product demos and presentations with screen sharing matters most. Run both through a week of actual calls to see which suits your workflow.

Voice-based AI roleplay platform that lets sales reps practice high-stakes conversations against realistic AI buyers and get instant coaching.
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.

Exec is an AI roleplay and training platform designed to help sales reps, leaders, and support staff practice high-stakes conversations before they happen with real customers.

The platform supports custom scenario creation and includes screen-sharing functionality so reps can practice product demos and presentations, not just talk tracks. After each roleplay, Exec provides instant performance insights, including actionable improvement tips and an AI coach that can explain scores, surface growth areas, and run short follow-up sessions to work through specific gaps. For managers and enablement teams, Exec offers analytics dashboards tracking skill development over time, performance trending, leaderboards, certification, and integration with existing learning management systems. It maintains SOC 2 Type II certification and states it does not use customer data to train its models. Exec is aimed at enterprise sales and revenue teams that want to close the gap between training content and real behavior change through repeated, measurable practice. Pricing varies by plan.
