As answered by people managing Underpriced AI and ContextForge.dev.
Underpriced AI's answer
My wife flips thrift store and estate sale finds, and I watched her spend 10+ minutes researching every item on her phone before deciding to buy. I'm a software engineer, so I built a tool to do it in seconds — snap a photo and know what it's worth. What started as a side project to help her source faster evolved into a full reseller workflow: scan, price, list, and track.
ContextForge.dev's answer:
ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol — so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.
Underpriced AI's answer
It's the only tool that combines AI image recognition with real sold price data from 6+ marketplaces in a single scan. Most competitors either identify items OR look up prices — not both. You get identification, fair market value, comparable sales, and a ready-to-post listing from one photo.
ContextForge.dev's answer:
ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once — Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf — not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing — all through a single MCP server you add with one command.
Underpriced AI's answer
Pricing is based on actual sold data across eBay, Poshmark, Mercari, Facebook, Etsy, and Depop — not just eBay asking prices. There's no monthly commitment required; you can buy a 5-scan pack for $4 and try it. It also goes from scan to eBay listing in two clicks, which no other pricing tool does.
ContextForge.dev's answer:
Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.
Underpriced AI's answer
Thrift store flippers, estate sale buyers, antique dealers, online resellers, and anyone who buys and sells secondhand goods. Also useful for people valuing donated items for tax purposes or settling estates.
ContextForge.dev's answer:
Software developers and engineering teams who use AI coding assistants — Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf — and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.
Underpriced AI's answer
Next.js, TypeScript, Claude AI (Anthropic) for image analysis, Perplexity AI for real-time market research, eBay Browse API for live listings, PostgreSQL, AWS, and Vercel.
ContextForge.dev's answer:
Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.
