How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and SyncWords when delivering accessible, fcc-compliant live captions for a broadcast matters most. Try them side by side on real calls before deciding — needs vary by team.

Live AI captioning, subtitling, and voice-dubbing platform for webinars, streams, and hybrid events with real-time multilingual output.
Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

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. It best fits broadcasters, media teams, and event organizers who need accessible, multilingual live captioning and translation at scale. Pricing varies by plan.
