Multi-agent AI cross-references everything
Unlike single-prompt tools, DoubleCheck runs a Reviewer-Critic loop that argues with itself across multiple passes. Each pass catches issues the previous one missed.
Reviewer extracts
Every claim, date, number, name, and promise
Critic challenges
Cross-references, verifies math, finds contradictions
Loop repeats 3×
Each pass refines findings and catches more
Get a severity-coded report with fixes
Every finding comes with severity (Critical / Warning / Info), the exact location in your document, evidence, and a suggested correction you can apply with one click.
- Color-coded severity levels
- Exact page & paragraph references
- Side-by-side evidence
- One-click suggested fixes
- Export as PDF or Markdown
Revenue total mismatch
Summary states $4.2M but table rows sum to $3.8M
Date inconsistency
Clause says "March 15" but referenced email says "March 22"
Recipient name differs from email signature
Why it catches more than other tools
Single-prompt AI misses nuance. DoubleCheck's multi-agent architecture is designed to argue, re-check, and verify — like having a team of auditors.
Typical AI tool
One prompt → one response. No verification. No second opinion.

See it in your industry
Every industry has high-stakes documents. Here's how DoubleCheck catches errors in yours.
Finance & Accounting
The problem
Quarterly report shows $4.2M in the summary but the tables add up to $3.8M.
What DoubleCheck does
Flags the $400K mismatch with both values, exact page, and a suggested fix.
Legal & Compliance
The problem
Contract clause 3.2 says "30-day terms" but clause 7.1 references "45-day terms".
What DoubleCheck does
Highlights the contradiction with both clause references and severity level.
Marketing & Sales
The problem
Proposal claims "99.9% uptime" but the attached SLA says "99.5%".
What DoubleCheck does
Cross-references the claim against the attachment before you hit send.
Operations & HR
The problem
Updated leave policy in the handbook but the benefits summary still shows old terms.
What DoubleCheck does
Compares both documents and flags every outdated reference with suggested edits.

Your data stays yours
We built DoubleCheck with enterprise-grade security from day one. Your documents are never used for training.

Names, emails, phone numbers, and addresses are replaced with synthetic data before AI analysis. Results are de-anonymized for you.
End-to-End Encryption
All data is encrypted in transit (TLS 1.3) and at rest (AES-256). Your files are never accessible to our team.
EU Data Residency
All data is stored in EU data centers. We never transfer your documents outside the EU.
Self-hosted LLM Option
Enterprise plans can use on-premise Llama or Mistral models — your data never leaves your infrastructure.

Enterprise SSO via SAML/OIDC. Fine-grained permissions for who can view, analyze, and export.
Frequently asked questions
What file formats does DoubleCheck support?
PDF, DOCX, XLSX, CSV, TXT, PNG, JPG, and email threads (EML/MSG). We also support pasting raw text directly in the chat.
How is this different from ChatGPT or Grammarly?
ChatGPT is a general assistant. Grammarly checks grammar. DoubleCheck specifically cross-references facts, numbers, dates, and claims across documents — using a multi-pass Reviewer-Critic architecture that catches what single-prompt tools miss.
Is my data used to train AI models?
Never. Your documents are processed in isolated sessions, encrypted at rest, and never used for model training. You can enable PII anonymization for an extra layer of protection.
Can I connect my email or cloud storage?
Yes. We support Gmail, Outlook, Google Drive, OneDrive, Dropbox, Slack, and Notion via one-click OAuth. New files and emails are analyzed automatically.
How long does an analysis take?
Most documents are analyzed in under 30 seconds. Complex multi-document comparisons may take up to 2 minutes. You get a real-time progress indicator.
Can I use DoubleCheck for my team?
Yes. Our Enterprise plan includes team seats, SSO, role-based access, shared flows, and a central admin dashboard. Contact us for volume pricing.
What happens if I exceed my plan limits?
You'll get a notification and can upgrade instantly. We never auto-charge or cut off access mid-analysis.
