1. AI Notetaking
ホタルAI: The ai notetaker joins your meeting and captures every word. It works as a hands-free メモを取る人 so you can focus on the talk. No one has to type meeting notes by hand.
メムAI: Mem is not a meeting note taker. It is a note taking app for your own ideas and research. The AI saves notes effortlessly and links them so you never forget a thought.

ホタルAI: This is a true ai transcription tool. It generates transcripts in real time and supports audio recording from uploaded audio files. The transcription tool reads more than 60 languages with about 90% accuracy.
メムAI: Mem does not transcribe audio or video. Its Smart AI Writer helps you draft and polish writing instead. It is built to create content, not to turn speech into 文章.
⚠️ 警告： Only Fireflies AI handles audio and video. If you need to record and transcribe calls, Mem is not the tool for that job.
3. Summaries & Recaps
ホタルAI: After each call, it can summarize key moments into short meeting recaps. It pulls out the important moments and key topics so co workers who missed the meeting catch up fast.

最適な用途: Recording meetings, team transcription, and conversation intelligence
