What you can build on RelayModels.

Product categories where AI already delivers the most value — from aggregators to support agents.

A Cal.com-style scheduler

A calendar aggregator that suggests slots itself, writes emails to attendees and summarizes meetings.

Support like Intercom Fin

An AI agent answers from your knowledge base, looks up orders in your CRM and escalates only complex conversations.

Search like Perplexity

Your own vertical search: aggregate sources, rerank them and return an answer with citations.

An assistant like Notion AI

Writes, rewrites and structures documents right inside your product.

A code reviewer like CodeRabbit

Parses pull requests, comments on the diff and auto-generates change summaries.

Finance parsing like Ramp

Receipts, invoices and statements turned into strict JSON and expense categories.

The best products start before the first users.

We approve even if:

  • your audience is just you and your friends so far
  • you're a solo founder with no legal entity
  • AI is just one feature of the product
  • you have code but no polished landing page yet
