How Hosiqo compares and tests toolsFinal recommendation
Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and TwinMind when users who prefer a bot-free, privacy-conscious notetaker over tools that join the meeting 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.

TwinMind is an AI meeting assistant delivered as a Chrome browser extension and companion mobile app that captures, transcribes, and summarizes conversations from video calls and in-person meetings. The Chrome extension works alongside Google Meet, Zoom, and Microsoft Teams to produce real-time transcripts and then generate structured notes and action items after the call. Rather than sending a separate bot participant into the meeting, TwinMind transcribes the audio playing on the user's device, so there is no visible 'recording bot' announcement. The company emphasizes a privacy-first design: the product states that audio is not stored and that only text transcripts are kept, with data saved locally and optional encrypted cloud backup. TwinMind supports a large set of languages and lets users query their past conversations through an AI chat interface, positioning itself as a personal 'second brain' for recall. It markets a single experience spanning desktop browser and phone so meetings, voice notes, and ambient conversations can be captured in one place. The product is actively maintained and operating in 2025-2026. Pricing varies by plan. Check the official website for current pricing.
