---
## Risk Mitigation
### Known Risks
1. **API Costs**: ElevenLabs and Whisper can be expensive
- **Mitigation**: Use free Web Speech API as default, make premium APIs optional
2. **Audio Latency**: TTS/STT pipeline may feel slow
- **Mitigation**: Stream audio where possible, show clear loading states
3. **Cross-platform Issues**: Audio/shortcuts may behave differently
- **Mitigation**: Test on Linux/macOS/Windows early and often
4. **File Security**: Handling user files safely
- **Mitigation**: Strict file type validation, size limits, sandboxing
---
## Success Criteria
Phase 2 is complete when:
- ✅ Users can save, load, and export conversations
- ✅ Messages render with proper code highlighting and formatting
- ✅ TTS works with at least one voice provider
- ✅ STT works with Web Speech API
- ✅ Users can attach and discuss files
- ✅ Basic keyboard shortcuts are functional
- ✅ System tray integration works on Linux
- ✅ All features are documented
- ✅ No critical bugs or performance issues
---
## Timeline Estimate
**Optimistic**: 4 weeks
**Realistic**: 5-6 weeks
**Conservative**: 8 weeks
Depends on:
- Time available per week
- API complexity/issues
- Cross-platform testing needs
- Feature scope adjustments
---
## Next Steps
1. **Install dependencies** for conversation management and markdown rendering
2. **Implement conversation store** and basic save/load
3. **Create ConversationList component** for browsing history
4. **Enhance message rendering** with react-markdown and syntax highlighting
5. **Integrate ElevenLabs TTS** with settings UI
6. **Add voice input** with Web Speech API
7. **Implement file attachments** with preview
8. **Add system tray** and keyboard shortcuts
