AI-native marketplace

Shopping by intent, not filters: an AI-native marketplace that answers a shopper's plain-language request with reasoned picks, and shows sellers what people are looking for.

Whose need

People think about what they need in sentences: "a rain-proof tent for two, under $300." Marketplaces still answer with category trees and filter checkboxes. The right product gets buried under thousands of results, finding a gift eats an evening, and a return turns into a form marathon. Sellers have it no better: listing a product takes time, and demand stays invisible.

What I built

I designed Askwell as a marketplace where AI isn't a side feature but the interface itself. The search box gives way to an intent box. Shoppers say what they want; Askwell searches, narrows down, compares and explains every pick. Gift finding, photo search, review summaries, virtual try-on and conversational returns are all part of the same experience. Sellers get one-step listings from a photo and an assistant that surfaces demand before it peaks. And Askwell is open to AI agents, not just people: through MCP and UCP, other assistants can shop here too.

The flow

  1. The shopper writes what they need; Askwell breaks the sentence into meaningful tags.
  2. Hybrid search and LLM reasoning scan thousands of products and return results with a "why this" for each.
  3. Review summaries and a personal comparison settle the choice; virtual try-on removes the last doubt.
  4. After purchase, tracking, returns and exchanges happen in conversation, and every action waits for the shopper's approval.
  5. Sellers list a product from a photo; the assistant shows what people are searching for and what's missing from stock.

Key decisions

  • Intent instead of a search box

    Generative discovery doesn't return a ranked list. It plans several searches, reasons over the results and recommends with reasons, so shoppers always know why they're seeing a product.

  • Conversation and storefront on one surface

    Instead of a chat bubble squeezed into a corner, generative UI: the AI answers with product cards, comparison tables and return cards, not paragraphs. While the AI works, the interface dims; results flow back onto the light canvas. Shoppers can always tell when the AI is at work.

  • Every action that touches money or orders is approved

    Returns, exchanges and checkout steps go through human-in-the-loop approval. Layered guardrails, prompt-injection defenses and an eval suite running in CI (golden datasets, LLM-as-judge) make every answer measurable.

  • A marketplace open to agents

    Built for agentic commerce: with an MCP server and UCP/ACP support, a shopping agent in ChatGPT or Gemini can query the Askwell catalog in real time.
