What does Quartr do?

Quartr is an AI infrastructure platform that collects, structures, and delivers real-time data from public companies — including earnings calls, transcripts, filings, slides, and presentations. It takes the messy, scattered IR material that analysts usually hunt for across multiple investor relations pages and terminals, and makes it instantly searchable and AI-ready. The platform covers over 15,000 public companies across 65+ markets, offering live coverage of earnings calls, capital markets days, and conferences.

Quartr works through two main offerings: Quartr Pro, a research platform for investment professionals, and Quartr API, a data layer for developers and AI companies. With Quartr Pro, you can ask natural language questions across all IR materials, track changes in a company's messaging or KPIs over time, and get answers traceable back to original documents. The platform also integrates via MCP (Model Context Protocol) so you can pull live transcripts and filings directly into tools like Claude or Codex. Quartr API provides consistent, structured access to audio, transcripts, filings, and slides with a single identifier — no manual imports or middleware needed.

This tool is built for investment professionals, financial analysts, and AI teams that need accurate, timely data from public companies. Hedge funds, asset managers, and research platforms rely on Quartr to cut research time from hours to seconds. It's also used by AI companies like Perplexity to power live earnings call features. If your work involves qualitative public market research — understanding management tone, spotting inflection points, or monitoring competitors — Quartr makes the process faster and more reliable.
