Sidebar for ChatGPT Chrome extension
Die Sidebar für ChatGPT ist eine schnell wachsende Chrome-Erweiterung mit über 9.000 Nutzern, alles organisch gewachsen, ohne bezahlte Werbung. Sie bietet sofortige KI-Unterstützung direkt im Browser über eine übersichtliche, schlanke Sidebar. Die Kernfunktionen sind für immer kostenlos, mit einer optionalen einmaligen $29-Aufwertung für Power-User.
Chrome extension with 9,000+ organic users offering ChatGPT sidebar access, currently at $0 MRR with one-time $29 premium option.
Minimal - primarily first-mover advantage in specific sidebar implementation, weak defensibility
- Chrome users who frequently use ChatGPT and want faster access without tab switching
- Power users who need persistent AI assistance while browsing
- No clear premium feature differentiation
- Missing team/enterprise features
- No integration ecosystem
- Limited customization options
- Add Claude/Gemini multi-model support
- Build vertical-specific templates (coding, writing, research)
- Create team collaboration features
- Add local model support for privacy
Medium - browser extensions can spread through usage visibility, but limited by niche use case
- ChatGPT could build native sidebar feature
- Browser vendors may restrict extension capabilities
- OpenAI API changes could break functionality
- Low barrier to entry for competitors
$5,000-$15,000 for MVP (developer time + API costs)
