Technical to professional.
Developer shorthand becomes client-facing language. No more explaining what 'refactor' or 'race condition' means.
Context from linked issues.
AI reads your linked GitHub issues to understand the 'why' behind the code change, producing richer descriptions.
Customized per client.
Set tone and verbosity level per client. A technical CTO gets different language than a non-technical business owner.
Edit before you send.
AI gives you a head start. Every line item is fully editable before going to Stripe. You stay in control.
Sensitive detail redaction.
Starter keeps redaction enabled by default. Pro and Team can control it per account and per client.
One PR, multiple line items.
Large PRs that touch multiple features can be split into separate line items for clearer, more accurate billing.
Same code, different voices
Tailor your invoice language to each client's communication style.
feat: implement real-time collaboration with websockets

Added live collaboration features using WebSockets, allowing multiple users to work on the same document simultaneously.
