Found 3 issues:
Proactive defense, not just detection
DoubleCheck doesn't just find errors — it anticipates threats, blocks risks, and protects your communications before damage is done.
Anti-Phishing
Scans incoming emails for phishing links, spoofed senders, and social engineering patterns.
"Sender domain impersonates your bank — link redirects to a different host."
Spam Detection
Identifies spam patterns, suspicious attachments, and unsolicited bulk messages.
"3 emails from unknown senders with identical subject lines flagged."
Compliance Guard
PII detection, GDPR checks, and regulatory compliance — catch violations before they go out.
"Found 2 unredacted SSNs in the report marked for external distribution."
Outbox Protection
Check every draft before sending — block emails with critical errors or sensitive data leaks.
"Draft contains a client NDA but is addressed to an external recipient."
Proactive Anticipation
Detects patterns and warns you before issues escalate — trend analysis across your documents.
"3 contracts this month had the same date error — possible template issue."
Corrections & Advice
Every finding comes with a suggested correction and actionable advice — not just a flag.
"Replace $45,000 with $54,000 to match the signed contract on page 2."
Every kind of check. Built in.
Each analysis type targets a specific category of errors — from number verification to spam detection. Use them individually or combine them for a full audit.
Coherence Audit
Scans the entire document for internal contradictions, logical inconsistencies, and conflicting statements.
"Page 2 says the project starts in Q1, but page 7 references a Q3 kickoff."
Cross-Reference
Compares two or more documents to find mismatched facts, dates, numbers, and claims.
"The contract says $120K but the proposal says $112K — $8K discrepancy."
Numbers Check
Verifies all numerical data — totals, percentages, unit conversions, and arithmetic.
"Line items total $45,200 but the summary says $54,200 — transposition error."
Date Verification
Catches impossible dates, timeline conflicts, and scheduling contradictions.
"Delivery date March 15, 2025 is a Saturday — and the contract ends March 10."
Compliance / PII
Detects personal data, GDPR issues, and regulatory compliance gaps.
"Found 3 unredacted SSNs and 2 email addresses in the public-facing report."
Tone Analysis
Evaluates communication style — detects aggressive, passive, or inconsistent tone.
"The opening is formal but paragraph 4 switches to casual slang — inconsistent."
Spam Catcher
Analyzes emails for spam, phishing, and scam signals — detects misleading CTA links, subject/content mismatches, urgency tactics, and sender impersonation.
"CTA says "Verify your account" but link goes to paypa1-secure.xyz — phishing detected."
Custom Rules
Define your own verification rules — regex patterns, keyword lists, or natural language criteria.
"Flag any document that mentions 'confidential' without a classification header."

- Combine multiple triggers (email + schedule + webhook)
- Stack analysis types (coherence + numbers + dates)
- Chain actions (email report → Slack → block send)
- Add conditional logic (if critical → block, else → notify)
- Configurable per-step parameters and severity thresholds
