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.

Siro is an AI coaching and conversation intelligence platform designed specifically for in-person and field sales teams, a segment that traditional call-recording tools built for video meetings do not cover. Reps record their face-to-face customer conversations using Siro's mobile app, and the platform automatically transcribes and analyzes those recordings to surface coaching opportunities, objections, and selling behaviors. A real-time capability called Halftime delivers coaching cues mid-conversation. Siro includes Ask Siro, which lets sales leaders query recorded field conversations in natural language to find patterns in objections, competitive mentions, and rep performance, with answers linked back to specific recordings so managers can review and coach efficiently across many consultations. A self-coaching feature surfaces how stronger reps handled similar situations, giving reps an example to learn from. The platform also drafts follow-ups, flags key deal moments, and syncs data to CRM systems. Siro serves industries with heavy field and in-home selling, such as home improvement, home services, automotive retail, telecom, multifamily housing, and medical aesthetics. Pricing varies by plan. Check the official website for current pricing.
