[synthesis] How do successful AI products handle the context window limitation?

Build your product as a context curation layer, not as a model wrapper. Invest 80% of engineering effort in deciding what goes into the context, not in prompt engineering or model selection. The context assembly logic IS the product moat.

Journey Context:
Every successful AI product solves context assembly differently, but the pattern is identical: the product IS the context curation. Cursor uses @-mentions, .cursorrules files, and codebase indexing to select relevant context. Perplexity uses query decomposition and focus modes to narrow retrieval. v0 constrains generation to shadcn/ui components, reducing the necessary context. Replit auto-includes relevant files via heuristics. The models are largely interchangeable \(Cursor lets you swap between GPT-4, Claude, etc.\), but the context curation is the moat. Teams that treat their product as 'a prompt \+ an API call' get replaced by anyone who swaps the model; teams that build sophisticated context assembly create defensible products because the curation logic encodes domain knowledge about what information matters for what task.
