After 6 months of building in public, AI Nexus is live (Beta)

Hey IndieHackers!

I've been sharing my journey building AI Nexus in my build log, and today I'm opening up beta access.

What is it:

A professional workspace for working with AI models. Think ChatGPT, but you can use 100+ models (GPT-4, Claude, Gemini, etc.) through one interface, with real workflow tools.

The problem I'm solving:

I was paying for ChatGPT Plus ($20), Claude Pro ($20), and still using API calls for other models. Switching between tools killed my flow, I'd lose context, and I had zero organization.

The solution:

- 100+ models through one interface (OpenRouter integration)
- Projects with shared context files (upload once, use everywhere)
- Conversation branching (explore ideas without losing your thread)
- Intelligent context management (never hit token limits)
- BYOK pricing: €5/month + your own OpenRouter key

Tech stack:

- Frontend: React (SPA)
- Backend: Node.js
- Database: PostgreSQL
- Integration: OpenRouter API
- Hosting: [Your hosting]

Current status:

- Beta launched today
- Free 30-day trial (no credit card)
- Looking for 100-300 beta users for feedback
- After beta: €5/month BYOK or managed subscriptions (€15-75/month)

What I'm looking for:

- Honest feedback (what works, what doesn't)
- Bug reports (it's beta, there will be bugs 😅)
- Feature priorities (what should I build next?)
- Validation on pricing (does BYOK + €5/month make sense?)
