How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Senstone when dictating notes and reminders hands-free for busy professionals and students matters most. Run both through a week of actual calls to see which suits your workflow.

Senstone, currently sold as the Scripter, is a wearable voice assistant: a small device worn as a clip or pendant that lets you capture spoken notes, ideas, and dictations hands-free without reaching for your phone. Pressing the device records your voice, which its companion app then transcribes into text, organizes, stores, and lets you share. The platform handles voice-to-text in 12+ languages, including English, French, German, Arabic, and Ukrainian, and uses AI to clean up transcripts with punctuation and titling. Beyond plain transcription, the app generates summaries and action items, recognizes keywords, and can create lists and reminders via hashtags. The device syncs continuously with your smartphone and stores recordings locally when out of range, and notes can be shared to apps like Gmail. It is aimed at professionals, students, writers, and anyone who wants to capture thoughts on the move and turn them into searchable text. Senstone positions Scripter as an on-demand, pick-and-choose alternative to always-on life-logging wearables, emphasizing long battery life and selective recording.
