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.

Trellus is a real-time AI sales coaching and dialing tool delivered primarily as a lightweight Chrome extension that layers on top of existing sales engagement platforms such as Salesloft, Outreach, and HubSpot. Its real-time coaching analyzes call audio during live conversations to detect intent and signals and provides adaptive guidance, nudging reps to adjust pacing, listen more, or change approach as the conversation unfolds. Alongside live coaching, Trellus offers a parallel dialer that lets reps dial multiple lines at once to increase connect rates, with automated voicemail drops and number-health monitoring. The platform also includes AI voice agents that can handle inbound qualification or act as practice prospects for rep training, plus call analytics and performance scoring so managers can review conversations after the fact. A sales floor feature supports team collaboration. Because it runs as a browser extension on top of tools reps already use, Trellus is designed to add live guidance and faster dialing without requiring teams to migrate to a separate platform. It is aimed at sales development reps, account executives, and sales leaders focused on outbound calling performance. Pricing varies by plan. Check the official website for current pricing.
