How Hosiqo compares and tests toolsFinal recommendation
Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and Observe.AI when contact-center agents getting real-time prompts and after-call summaries during live interactions matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Observe.AI is a contact-center conversation intelligence platform that records, transcribes, and auto-scores customer calls and chats against quality scorecards while guiding agents in real time.
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.

Observe.AI is a conversation intelligence and CX platform built for contact centers. It captures customer interactions across voice, chat, and email, then transcribes them using a proprietary automatic speech recognition (ASR) engine that produces diarized transcripts with built-in PII redaction. On top of those transcripts, it layers large language models to automatically evaluate 100% of conversations against configurable QA scorecards, replacing the manual sampling most quality teams rely on. The platform surfaces sentiment, keyword spotting, and operational insights, and feeds them into coaching workflows for supervisors. For frontline agents, an Agent Copilot delivers real-time guidance, next-best-action prompts, and automated after-call summaries during live interactions. It's aimed at enterprise CX, support, and sales operations in regulated industries such as banking, insurance, healthcare, and travel, and offers hundreds of pre-built integrations with common contact-center and CRM systems. Distinct points include full-coverage auto QA, real-time agent assist tied to live sentiment, and an ASR engine tuned specifically for contact-center audio rather than general meetings.
