For me :

1. Makes the input easy - use familiar tool of choice -> WhatsApp/Telegram/etc

2. Integrate with anything - for example gmail through gog

3. Save to memory without prompting

4. Has a Soul.md which you can customize.

5. Have a reason to use a VPS

All of these are possible with Claude Code etc, however it's the the whole package that makes it more useful.
