The app includes an AI-powered summary engine. Your purchase includes 100 free AI credits to generate high-quality meeting insights via the cloud. You can also configure your own API key for unlimited custom summaries.
What does 'Lifetime' mean?
You get lifetime access to the version you purchase, with no monthly fees for the core app. All minor updates within the V1 lifecycle are completely free. When a major version (e.g., V2.0) is released, existing users get a 50% exclusive discount. Plus, if you purchased V1 within 30 days of the V2.0 release, your upgrade is 100% free.
Does the download require constant internet?
No. The initial download contains all the necessary AI models. Once installed, you can disconnect from the internet and run transcriptions completely offline.
How does the Subtitle Translation feature work?
The app includes built-in AI subtitle translation powered by DeepSeek-Flash. It translates segments line-by-line while strictly keeping original timestamp alignment. You can view bilingual subtitles side-by-side and export bilingual or target-only SRT files directly into video editing tools like Premiere Pro, Final Cut Pro, or CapCut. Each translation uses 1 AI credit.
