AI verification platform

Every claim, checked against the record it came from.

Stratum.AI validates AI-generated claims and human-written documents against authoritative sources before they reach users — delivering confidence-scored, evidence-backed corrections, and telling you plainly when it couldn't check something.

All SEC filers + 200M papers
40+ financial metrics
Every verdict linked to its source
What it looks like

A verdict you can actually follow to the source.

Badge on an AI answer
Verified — with the filing linked
Flagged — with the filed figure
Not checked — and why

When Stratum.AI can't verify something, it says so.

Most verification tools check whether output matches whatever context was retrieved. Stratum.AI checks the claim against the filing itself. A verdict is returned only when Stratum.AI has confirmed the right metric, in the right filing, for the right company. Everything else comes back as "not checked" — not a guess, not a silent pass.

That means fewer green badges. It also means the green badges mean something.

How it works

From claim to verdict in four steps.

Send us text from any source — AI agents, research drafts, analyst reports — and Stratum.AI verifies the claims inside it.

01

Send the text

Post any AI-generated or human-written text to /verify-text.

02

Identify the claim

Stratum.AI locates each claim and determines what it refers to and which source would settle it.

03

Check the source

The claim is compared against the authoritative record: SEC XBRL for financial figures, Semantic Scholar and CrossRef for citations.

04

Return a verdict

Verified, flagged with the correct value, or explicitly not checked — each linked to the source.

Domain Roadmap

The same verification engine, pointed at different authoritative records.

Live now
  • ✓Financial filings — SEC EDGAR
  • ✓Academic citations — Semantic Scholar, CrossRef
  • ✓Formula verification — SymPy
Roadmap
  • ○Factual claims — Wikidata
  • ○Healthcare drug data — FDA
  • ○Legal citations — CourtListener
  • ○Insurance and actuarial — source TBD

Every new domain is the same platform pointed at a new authoritative record. The constraint is whether an authoritative record exists — not whether the claim is a number.

Use cases

Where a wrong claim costs something real.

Independent research

Figures you publish under your own name.

You publish exact figures under your own name. Stratum.AI checks each one against the source before the note goes out.

Fintech

AI advisors that don't make up numbers.

An AI research tool quotes a revenue figure from the wrong fiscal year. Stratum.AI checks it against the filing and returns the filed number before it reaches a client.

Academic research

Citations that actually exist.

A writing assistant invents a journal name in a research paper. Stratum.AI flags the citation against CrossRef before it lands in the draft.

Healthcare and legal verification are on our roadmap, not live today.

Why Stratum.AI

What makes the verdict trustworthy.

01

Primary-source verification

Other tools check whether output matches whatever context was retrieved. A system that retrieved the wrong document passes that check and still ships a wrong claim. Stratum.AI checks against the authoritative record itself — the filing, the paper, the label, the court record.

02

Built to refuse

When Stratum.AI can't identify the subject, the claim, or the source that would settle it, it returns “not checked” rather than a guess. A false confirmation is worse than no answer, in any domain.

03

Every verdict is traceable

Each result names the source that settled it, the version or date of that source, and links to the record itself. No black boxes, no unexplained flags.

04

Not an evaluation framework

Evaluation tools score models before deployment against a test set. RAG feeds context in. Stratum.AI runs at the point of use, per claim, against the source itself — for the person whose name goes on the output. Works with any model, no retraining.

The platform

One verification engine, four surfaces.

LIVE

B2B verification API

A containerized FastAPI backend on AWS EC2 with Docker, HTTPS and REST APIs across five endpoints, fronted by AWS API Gateway. ChromaDB vector search, semantic embeddings and LangChain handle real-time claim extraction, evidence retrieval and confidence scoring.

BUILT

Chrome extension

Per-claim verdicts inline on any page you read. See below.

IN DESIGN

Domain verification agents

LangGraph-based RAG-verification agents, one per domain, coordinating when a claim spans several.

IN DESIGN

A2A super-agent

An agent-to-agent protocol super-agent using CrewAI and MCP tool integration, so any external AI agent can route its output through Stratum.AI for verification.

Drop-in API

One request. Structured verdicts back.

One POST with the text and the claimed figure. Back comes a verdict, a confidence score, the corrected value when there is one, and a link to the record that settled it.

app.ts
const res = await fetch(
  "https://api.stratumai.dev/verify-text",
  {
    method: "POST",
    headers: {
      "X-Stratum-Key": process.env.STRATUM_KEY,
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      text: "Apple reported net income of $93.736 billion in FY2024.",
      claimed_figure: "$93.736 billion",
    }),
  }
);

const result = await res.json();
// {
//   verdict: "verified",
//   confidence: 0.95,
//   correction: null,
//   source: "Apple Inc. 10-K (FY2024)"
// }
Why we're building this

The refusal is the product.

I built the verifier, then found it flagging correct numbers as wrong — it was checking them against the wrong metric. The fix wasn't a patch. It was deciding Stratum.AI should refuse to answer unless it's certain. That refusal is the product.

Security & Data Handling

Built with data minimization as a core principle.

What we store

Verification results (the claim, the verdict, the source) for service improvement and customer dashboards. We do not store your underlying business data beyond what's needed to verify a claim.

What we don't do

We don't use customer data to train any models. We don't share verification logs with third parties.

Third-party sources

Financial claims are checked against SEC EDGAR (public government data). Citations are checked against Semantic Scholar and CrossRef (public academic databases). No private customer data is sent to these sources — only the claim being verified.

Enterprise needs

On-premise deployment, SOC 2 compliance, and dedicated audit logs are on our roadmap for enterprise customers. If data residency or compliance certification is a requirement for your team, reach out and we'll prioritize accordingly.

Jurisdictions

Users attest at signup that they are not located in a US-sanctioned country, and the Terms of Service prohibit use from those jurisdictions. Network-level enforcement is on our roadmap.

Early-stage notice: Formal security certifications and a complete data processing agreement are in progress — contact us before sending sensitive production data.

Chrome extension

Verification wherever you read.

Stratum.AI runs on any page you browse. When it finds a claim it can check, it places a badge beside it — verified, flagged with the correct value, or explicitly not checked. Hover to see the source.
