How Hosiqo compares and tests toolsFinal recommendation
Shortlist Acta.ai when sales discovery calls that need deal briefs and follow-up tasks matters most, and Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Brazilian Portuguese-focused AI voice and transcription platform offering on-demand transcription plus a meeting assistant and AI notes, with credit-based and subscription plans.
Acta.ai is an AI meeting assistant developed by Agilean Solutions Private Limited, an India-based company. It connects to a user's Google or Microsoft account and calendar, and its agent automatically joins scheduled meetings on Google Meet, Microsoft Teams, and Zoom. After a meeting, Acta.ai records and transcribes the conversation and then analyzes it to generate a concise summary, a list of decisions, and actionable tasks. A distinguishing element is its persona-based approach: the platform offers domain-specific agents oriented toward business functions such as Sales, Engineering, Recruiting, Project Management, Finance, Customer Support, and HR, with the ability to convert discussions into role-appropriate outputs like product requirement notes, ticket-style items, deal briefs, or assessment reports. It also includes an 'Ask Acta' assistant for querying meeting content and provides a Chrome extension. Acta.ai is positioned for cross-functional teams that want meetings translated into structured follow-up work rather than only a raw transcript, and it markets itself around moving from 'what was said' to 'what needs to be done.' The product is actively operating, offering a free trial alongside paid tiers. Pricing varies by plan. Check the official website for current pricing.

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.
