How Hosiqo compares and tests toolsFinal recommendation
Shortlist AudioPen when capturing and refining personal ideas, journal entries, or brainstorms by voice matters most, and Callabo when logging sales and customer meetings into crm tools like salesforce or hubspot matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Korean AI meeting-notes service from Return Zero that records, transcribes, summarizes, and analyzes meetings for individuals and teams.
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.
