Read any filing in seconds.
Cruxa turns long financial filings, research reports and prospectuses into structured, decision-grade briefs — key metrics, risks, management-tone shifts, and a bottleneck view — right in your browser side panel.
Bring your own AI key · runs locally · not investment advice.
Built for people who read filings for a living
Every brief follows the same rigorous structure, so you know exactly where to look.
Structured brief
TL;DR, key financials table, risks & red flags, management tone, bottleneck view, and a "to verify" list.
Multilingual
UI and output in English, 简体/繁體中文, 日本語, 한국어, Français, Deutsch, Español — defaults to your browser language.
Streaming
Long documents render progressively as the model writes — no waiting for the whole thing.
Your framework
Inject your own analytical lens so every brief follows your method — your edge, not a generic summary.
Anti-hallucination
Numbers are grounded in the source; anything unverifiable is flagged, never invented.
Works where you read
SEC EDGAR, cninfo, Xueqiu, X/Twitter, plus a generic reader for any page.
Three steps
Install once, add your key, and summarize anything.
