Pricing

Free and open source (MIT); the hosted version at hyperresearch.ai has its own pricing.

Overview

Hyperresearch is an MIT-licensed add-on that sets up a multi-step research pipeline inside Claude Code or OpenAI Codex. From one question it gathers sources from the web and scholarly databases, drafts a report and has a checker confirm that each cited source backs its sentence before the report is finished. Every source it reads is stored in a local searchable vault that later sessions reuse. A hosted version at hyperresearch.ai runs the same pipeline without a local install.

Key features

  • Per-claim citation checking
  • Persistent local source vault (Markdown and SQLite)
  • Scholarly search: OpenAlex, Crossref, CORE, SEC EDGAR, FRED and more
  • Resumable runs
  • Claude Code and Codex plugins or skill
