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.

SecureMemo is an AI meeting-minutes application developed by Nishika, Inc., a Japanese company, and is designed for organizations that handle confidential or sensitive meetings and cannot use cloud-based services. It runs in on-premise, closed-network, or fully offline environments, processing audio entirely within the customer's own infrastructure so that voice data never leaves the organization to an external cloud. SecureMemo is powered by Nishika's in-house speech recognition AI called "shirushi," which the company states maintains high recognition accuracy even with background noise or overlapping speech, and can transcribe audio in roughly 100 languages including Japanese, English, Chinese, and Thai. The product offers five core capabilities: accurate voice recognition, automatic speaker identification, automatic meeting-minutes generation that organizes decisions and key points, translation across about 100 languages, and custom terminology support through word registration for specialized vocabulary. The workflow follows a simple three-step process of transcription, speaker recognition, and summarization. It is offered in standalone, USB-dongle, and client-server deployment models, with case studies spanning police, government agencies, universities, manufacturers, and financial institutions. A two-week free trial of the standalone version is available. Pricing varies by plan. Check the official website for current pricing.
