Things Only Solid# Can Do

These aren’t features. They’re capabilities no other platform has.

SmartRouter

Picks the optimal AI model for every single task across 8 LLM providers. Not random. Not default. Optimal — based on task type, cost, and performance history.

Voice AI

AI answers your business phone with a custom personality. Books appointments, checks inventory, answers questions — all in natural conversation. 10 voice options.

AI-Native Websites

Your website is a living catalog. When someone asks ChatGPT "how many dresses do you have?" — the AI queries your MCP endpoints and gives a real answer with real data.

Vibe Modification

Build anything in plain English. "Add a teeth whitening service for $299" — done. "Create a pricing page with 3 tiers" — done. Always reversible, never destroys data.

CognitiveLimiter

9-layer AI cost control. Per-company budgets, rate limiting, spike detection. Your AI spend is controlled automatically — no surprise bills.

55% AI Codebase

26,631 lines of AI infrastructure code. Not API wrappers. Real systems: routing, cost control, security, voice, agents. AI IS the platform, not a feature bolted on.

Stop Paying for Software. Start Using Infrastructure.

AI agents. Voice AI. Living websites. SmartRouter. The house where AI lives. $89/month. 5-minute setup.
