In active development — financial verification is live in testing. Join the waitlist for early access.

Real-time LLM verification

The layer that keeps AI grounded.

No guessing. No opinions. Just verification.

Stratum.AI catches wrong answers mid-generation, corrects them on the fly, and scores every claim's confidence.

How it works

Four steps from claim to confidence.

01

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.

02

Parse the stream

As tokens arrive, we extract atomic claims — numbers, dates, names, citations.

03

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.

04

Correct & score

Wrong facts are rewritten with sources. Every claim gets a confidence score. You ship trust.

Use cases

Built for industries where wrong answers cost real money.

Fintech

Trade copilots that don't fabricate filings.

Verify P/E ratios, earnings, balance-sheet items against SEC EDGAR before they reach an analyst.

EdTech

Tutors that cite real papers.

Cross-check every citation against arXiv and Crossref. Strike out invented authors before students see them.

Healthcare

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.

Legal

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.

Built for claims with a checkable answer

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.

What Stratum.AI is not

Clarity matters. Here's what we don't do.

Not A new foundation model.
We sit on top of yours.
Not A prompt-engineering layer.
We verify the output, not the input.
Not An eval framework.
We run live, in production, per request.
Not A vector DB.
We query authoritative sources, not embeddings.
Not A bias detector.
We verify arithmetic and factual records, not opinions, predictions, or editorial framing. Those require human judgment — and we say so.
Drop-in API

Two lines of code. Zero infrastructure.

Change one base URL. Keep your existing prompts, tools, and streaming logic. Stratum.AI is OpenAI-compatible.

  • Currently built for OpenAI — Anthropic SDK support is on our roadmap
  • JSON-based API — streaming (SSE) support is on our roadmap
  • Per-claim confidence scores included in every response

Why we're building this
"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."
