Example Conversation
[Phone rings]
Claude: "Hey Alex! I see you're working on the user-service
project. What would you like to discuss?"
You: "I'm having trouble with the authentication middleware.
Can you take a look at auth.py?"
Claude: "Sure, let me read that... I see you're using JWT
tokens. The issue might be on line 45 where you're checking
the expiry. You're comparing timestamps in different formats..."
You: "Oh, that makes sense. What's the fix?"
Claude: "You should convert both to Unix timestamps before
comparing. I'd suggest using datetime.timestamp() on line 45..."Transcripts
Calls are automatically transcribed and saved:
