How Hosiqo compares and tests toolsFinal recommendation
Shortlist Akkadu when adding multilingual live captions and subtitles to conferences, webinars, and hybrid events matters most, and OpenWhispr when turning rough in-meeting notes into structured summaries and action items matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Akkadu, built by Akkadu Technology, is a platform for breaking down language barriers in live and recorded settings. It listens to a speaker's audio and produces real-time AI live captions and subtitles in more than 90 languages, and can deliver an AI voice translation that voices a speaker's words in another language. Beyond automated transcription and translation, Akkadu also offers remote simultaneous interpretation (RSI), connecting human interpreters to events, plus human live captioning for higher-accuracy needs. It is available as a desktop and web-based application and is designed to work alongside common video conferencing tools such as Zoom, Microsoft Teams, Webex, and Google Meet, as well as on-site and hybrid events. The company states it does not store voice data and gives users control to delete transcripts. Akkadu targets event organizers, conferences, corporate meetings, universities, content creators, and language service providers who need multilingual accessibility. It is offered on a pay-as-you-go hourly model with a free limited demo tier.

OpenWhispr is an open-source desktop application for macOS, Windows, and Linux that converts speech to text and includes a meeting notes capability built on the same engine. Its core function is global-hotkey dictation that inserts transcribed text at the cursor in any application, but it also ships an AI Notepad for meetings, an AI Chat that can reference past meetings, and an audio upload feature for transcribing recorded files. For meetings it captures the computer's audio directly rather than sending a bot into the call, transcribes the conversation in the background, and combines rough notes with the transcript to produce structured minutes that highlight decisions, action items, and next steps. Transcription can run locally using bundled Whisper and NVIDIA Parakeet models or connect to cloud models with a bring-your-own-key setup, and the project emphasizes that audio can be processed and discarded for privacy. The codebase is publicly available on GitHub and the app is actively maintained through 2026. It is aimed at developers, writers, and individuals or small teams who want a private, auditable, cross-platform transcription and meeting-notes tool. Pricing varies by plan. Check the official website for current pricing.
