Liner helps developers build AI apps with search agents and lower-cost search tools. Add web search, academic search, cited answers, deep research, and visual answers to your product. Web Search starts at $1 / 1K requests — 1/10 of OpenAI’s public web search tool-call price.
Hey Product Hunt 👋
I’m Stellar from Liner. Today we’re launching Liner Developer Platform, search agents for AI products, plus lower-level tools for teams that want to build their own workflows.
Most AI apps need more than model memory. They need to search fresh sources, cite evidence, research complex questions, and sometimes explain the answer visually.
Liner gives developers two ways to build that:
Agents
🔎 Search Agent — searched answers with citations and source evidence
⚡ Quick Answer Agent — fast, lightweight cited answers
📄 Deep Research Agent — multi-step research reports
📊 Visual Answer Agent — answers with interactive visuals
Tools
🌐 Web Search — structured web results
📚 Academic Search — scholar results and paper metadata
🧩 Visualization — turn queries into embeddable HTML visuals
We’d love feedback from people building AI search apps, copilots, agents, RAG workflows, and research tools.
Question for builders: would you rather start with a ready-made search agent, or use lower-level search tools and build the answer flow yourself?
Been playing with it for a bit. Solid value for the price 👍
The fastest & cheapest search API I've ever used. Amazing
This api is amazing. I’m using this for my personal project, and I really appreciate for this great product! Thank you liner team!
