How Hosiqo compares and tests toolsFinal recommendation
Shortlist AudioPen when capturing and refining personal ideas, journal entries, or brainstorms by voice matters most, and SyncWords when delivering accessible, fcc-compliant live captions for a broadcast matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Live AI captioning, subtitling, and voice-dubbing platform for webinars, streams, and hybrid events with real-time multilingual output.
AudioPen is a voice-to-text tool that captures spoken thoughts and turns them into polished written notes. You record your voice (or upload an audio file), and AudioPen transcribes the speech, then rewrites it into clear, structured text by fixing grammar, cutting filler words, and organizing rambling input into coherent prose. Rather than producing a verbatim transcript, it reshapes what you said into finished writing in a style you select or train over time, with preset and custom styles available. It supports multiple languages and can transcribe speech in one language while writing the output in another. A SuperSummaries feature combines several notes into a single cohesive summary, and existing notes can be reformatted for different purposes such as emails or to-do lists. Built by independent developer Louis Pereira, it runs across iOS, iPad, Apple Watch, Android, Mac, and a Chrome extension, with Zapier and webhook integrations for sending notes elsewhere. It is aimed at people who think out loud and want to convert informal speech into professional written content.

SyncWords is an AI-powered platform for delivering live and recorded video content to multilingual audiences through real-time captions, subtitles, and voice dubbing. For live scenarios, it produces frame-accurate AI captions that meet broadcast accessibility standards such as CEA-608/708, and its SyncWords Live offering provides professional captioning and real-time translated subtitles for webinars, streaming services, and hybrid events. The platform translates into a wide range of languages, including non-Latin scripts such as Cyrillic, CJK, Arabic, Hebrew, and Thai, and recent engineering work has driven latency down to roughly a second or less even in demanding live environments. Its newer Vocalics capability adds real-time AI voice dubbing that aims to preserve a speaker's tone and delivery across languages. Content is delivered through no-download widget URLs as well as streaming formats like HLS, SRT, CMAF, and VTT, with integrations spanning platforms such as AWS, YouTube, and Vimeo. SyncWords reports processing tens of thousands of events and hundreds of thousands of hours of media, and it received an industry innovation award in 2025, confirming active operation.
