How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aqua Voice when dictating emails, documents, and slack messages hands-free across desktop apps matters most, and Callabo when logging sales and customer meetings into crm tools like salesforce or hubspot matters most. Try them side by side on real calls before deciding — needs vary by team.

Korean AI meeting-notes service from Return Zero that records, transcribes, summarizes, and analyzes meetings for individuals and teams.
Aqua Voice is an AI dictation tool built by Aqua Voice, Inc. (a Y Combinator startup) that converts spoken words into written text in real time. Rather than a standalone transcription window, it works system-wide: users hold a key (such as Space) and speak, and the dictated text is inserted into whatever app is in focus, including Gmail, Google Docs, Slack, code editors, and AI chat tools. It runs on macOS and iOS, with the iPhone app now live. Aqua is powered by Avalon, the company's proprietary speech-to-text model trained on prompt-style speech, code, and email, and it refines grammar and phrasing as you talk. It supports context awareness of on-screen content, a custom dictionary for technical terms and names, natural-language editing commands ("make this a list," "rephrase that"), style adaptation, and multilingual input across dozens of languages. It is aimed at developers, knowledge workers, and content creators who want a faster alternative to typing for emails, documents, messages, prompts, and code.
