JustBeforeGo.io — AI travel planner
Free, ad-free, no-card AI travel planner that turns a 5-step form into a real itinerary.
About
Asking an LLM to plan a whole trip in one shot is slow and flaky. JustBeforeGo turns a short questionnaire into a full itinerary, generated as five parallel chunks over an async AWS pipeline (API Gateway → SQS → Lambda). That cut average generation from 50s to 30s (40% faster), lifted the success rate from 85% to 95%, and reduced cost per request by 25% — while staying free, ad-free, and card-free.
What's interesting
- Chunked generation (5 parallel calls) cut itineraries from 50s to 30s
- Success rate 85% → 95%; ~25% lower cost per request
- Async AWS pipeline (API Gateway → SQS → Lambda) auto-scales 0→20 workers
- MCP-based dedup so repeat trips never resurface the same suggestions
- Free, ad-free, no card required
