How Hosiqo compares and tests toolsFinal recommendation
Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and StreamAlive when collecting live anonymous polls and sentiment during large broadcasts matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

StreamAlive is a live audience engagement platform built to make large, broadcast-style meetings such as company town halls and all-hands sessions interactive. Instead of requiring attendees to scan QR codes or open separate apps, it turns the existing meeting chat into a participation channel, working across Zoom, Microsoft Teams, Google Meet, YouTube Live, and in-person presentations. Presenters can run multiple poll types (open-ended and multiple-choice power polls, rating polls), generate live word clouds from chat responses, drop pins on interactive maps, spin selection wheels, and collect emoji reactions, all rendered visually on screen in real time. For town halls and all-hands, its question management is a core draw: StreamAlive automatically detects and curates audience questions out of the chat stream so moderators do not miss them. Its AI layer, branded StreamAlive AI, can generate ready-to-use interactions from an uploaded presentation or topic description, summarize chat discussions with insights and notable quotes, and produce visualizations based on what the audience types. The product is delivered as a browser-based SaaS tool aimed at presenters who want higher engagement and clearer feedback during company-wide and webinar-style meetings. Pricing varies by plan. Check the official website for current pricing.
