How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and SubtitleBee when adding accurate, styled captions to social and marketing videos matters most. Try them side by side on real calls before deciding — needs vary by team.

Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

SubtitleBee is a browser-based AI tool that automatically converts spoken audio and video into text and generates synchronized, styled subtitles. Beyond captioning marketing clips and social videos, it offers a dedicated audio-transcription mode that handles interviews, lectures, meetings, voice memos, webinars, and podcasts: users upload a recording, select the source language, then review and edit the AI-generated transcript in an in-browser editor before exporting. It recognizes a wide range of languages and can translate captions across many of them, making it useful for global and accessibility-focused workflows. Transcripts and subtitles can be downloaded in standard formats including TXT, SRT, VTT, and ASS. Additional editing tools let users restyle captions (font, color, size, opacity), resize and crop video for different platforms, and add overlay "supertitles." It targets content creators, podcasters, educators, marketers, and professionals who need fast, editable transcripts and captions without technical skills. SubtitleBee has been operating since 2019 and runs entirely in the browser.
