AI Hallucinations Cost $67 Billion a Year. Stratum.AI Stops Them in Real Time.
Stratum.AI is the verification platform for any claim in any document — AI-generated or human-written. Financial figures checked against SEC filings. Citations checked against academic databases. More domains coming. API, Chrome extension, and document upload — one platform, three surfaces.
87% of financial hallucinations caught. 3 verifiers live. Real SEC EDGAR data.
Same verification engine. Three surfaces.
Whether you’re a developer, a student, or a professional — Stratum.AI works where you work.
B2B API
One endpoint. Every AI output verified against real SEC filings before it reaches your users. 10,000 free verifications/month. No infrastructure needed.
Get API Access →Chrome Extension
Auto-detects financial figures and citations on any page — ChatGPT, Google Docs, anywhere. Green badge = verified against SEC filing. Red badge = flagged with correction. Free to install.

Upload any PDF, Word doc, or paste text. Get back an annotated version showing every wrong figure with corrections and real source citations. No code required.
Join waitlist →A verification platform with five composable capabilities.
Stratum.AI is a verification platform with five composable capabilities — classification, verification, confidence scoring, automatic correction, and source routing — powered by an authoritative source network connecting to real ground truth.
Not another AI checking AI. The actual SEC filing. The actual academic database. The actual government record.
Two ways to integrate: /verify for LLM pipelines, /verify-text for any pre-generated text from any source.
Built for anyone who can’t afford to be wrong.
Developers & Companies
One line of code. Every AI output verified against authoritative sources before reaching your users. Financial claims live. Academic citations live now.
Students, Researchers & Professionals
Real-time fact-checking on any page. ChatGPT, Google Docs, anywhere. Highlights wrong claims instantly. No code. Free to install.
Teams Publishing Documents
Pass any report, brief, or analysis through /verify-text. Consulting reports, legal briefs, research papers — wrong figures and fabricated citations caught before they reach anyone.
From verification platform to the trust layer for AI agents.
Verification Platform
Five composable capabilities. Financial verification live. Citation verification live now. Any AI system or pipeline can call it.
Chrome Extension
Real-time verification on any page you browse. Stratum.AI automatically detects financial figures and citations, badges them instantly, and shows the real source on hover. Free to install.
Domain Agent Network
Specialized agents — financial, citation, healthcare, legal — built on top of the platform. Each agent is an expert in its domain. They coordinate with each other when a task spans multiple domains.
Super Agent + Agent-to-Agent Protocol
One orchestrating super agent any external AI agent can register with. Agents talk to agents. Agents pay agents. Stratum.AI becomes the trust layer underneath the entire AI agent ecosystem.
Watch Stratum.AI catch a hallucination mid-stream.
Four steps from claim to confidence.
Stratum.AI works two ways: point any LLM-powered product through our API, or send us text directly from any source — AI agents, research drafts, analyst reports — and we verify the claims inside it.
Proxy the LLM
Point your SDK at Stratum.AI's endpoint. We pass the request to OpenAI, or your own model. Anthropic support is on the roadmap.
Parse the stream
As tokens arrive, we extract atomic claims — numbers, dates, names, citations.
Verify in flight
Each claim is checked against authoritative sources: SEC EDGAR for financial figures, Semantic Scholar and CrossRef for citations, FDA databases for drug data, court records for legal claims. If there's no authoritative source, we don't guess — we flag it as unverifiable.
Correct & score
Wrong facts are rewritten with sources. Every claim gets a confidence score. You ship trust.
Stratum.AI is built with data minimization as a core principle.
The same verification engine, pointed at different sources of truth.
Every new domain takes the same infrastructure, just a new authoritative source. That’s what makes this a platform, not a point solution.
Built for industries where wrong answers cost real money.
Trade copilots that don't fabricate filings.
Verify P/E ratios, earnings, balance-sheet items against SEC EDGAR before they reach an analyst.
Tutors that cite real papers.
Cross-check every citation against arXiv and Crossref. Strike out invented authors before students see them.
Drug data that matches the label.
Verify dosages, interactions, and contraindications against FDA labeling and drug interaction databases before AI-generated medical information reaches a clinician or patient.
Citations that survive a court check.
Cross-check case citations and statutory references against real court records before they reach a brief. Catch fabricated case law before a judge does.
We verify claims that have a provable answer.
Every claim an LLM makes falls into one of two buckets: claims with a checkable answer, and claims without one. "Apple's P/E ratio is 56.2" has a checkable answer — you can compute it. "This stock looks risky" does not. Stratum.AI lives entirely in the first bucket. We verify claims that have a provable answer, not ones that require opinion or judgment.
Clarity matters. Here's what we don't do.
Two lines of code. Zero infrastructure.

"LLMs hallucinate 10% of the time. In fintech, that's a lawsuit. In research, that's a retraction. Stratum.AI fixes that in real time."
