|
||||
|
||||
## COMPARISON TO ALTERNATIVES
|
||||
|
||||
### Grimlock vs Slack
|
||||
```
|
||||
Slack:
|
||||
- Third-party service ($8-15/user/month)
|
||||
- AI as add-on (Slack AI)
|
||||
- Limited customization
|
||||
- Data on Slack servers
|
||||
- Generic AI responses
|
||||
|
||||
Grimlock:
|
||||
- Self-hosted (control costs)
|
||||
- AI-native participant
|
||||
- Fully customizable
|
||||
- Your data, your servers
|
||||
- Context-aware AI with company knowledge
|
||||
```
|
||||
|
||||
### Grimlock vs Microsoft Teams
|
||||
```
|
||||
Teams:
|
||||
- Complex enterprise software
|
||||
- Part of Office 365 bundle
|
||||
- AI as Copilot (separate cost)
|
||||
- Microsoft ecosystem lock-in
|
||||
|
||||
Grimlock:
|
||||
- Simple, focused tool
|
||||
- Standalone platform
|
||||
- AI included natively
|
||||
- Platform agnostic
|
||||
- Open architecture
|
||||
```
