How Crexto Works
From raw evidence to verifiable proof — a 7-step AI intelligence workflow that helps you understand, decide, and optionally prove.
Bring Your Evidence
Upload a screenshot, paste a product listing, share a contract, or describe a situation. Our agents accept images, PDFs, text, URLs, and raw data.
- Screenshots of product listings or websites
- PDF contracts, invoices, and legal documents
- Blockchain transaction hashes or wallet data
- Copy-pasted text from emails or messages
- URLs to online stores or project pages
Choose a Specialized Agent
Each of our six agents is trained for a specific domain. The agent you choose determines the analysis framework, the questions asked, and the structure of your report.
AI Extracts & Analyzes
Your chosen agent extracts objective facts from the evidence, identifies positive and negative signals, detects patterns, and builds a structured assessment — not a generic summary.
- Extracts every verifiable fact from the input
- Identifies positive signals and red flags
- Detects pressure tactics, inconsistencies, or gaps
- Applies domain-specific evaluation frameworks
Understand the Assessment
Receive a structured intelligence report with a clear verdict, confidence score, evidence breakdown, recommended actions, and questions you should be asking.
- Clear verdict with confidence percentage
- Positive signals vs. concerns side-by-side
- Agent-specific analysis (value factors, trust signals, contract clauses...)
- Actionable recommendations and missing information
Make Your Decision
Use the intelligence report to make an informed decision. The AI gives you the evidence and assessment — you decide what to do with it.
- Crexto does not make decisions for you
- Reports include explicit disclaimers
- AI confidence reflects evidence quality, not certainty
- Always verify critical decisions independently
Create On-Chain Proof
Optionally, anchor a cryptographic fingerprint of your analysis on the Base blockchain. This creates an immutable, timestamped record — without exposing your documents.
- SHA-256 hash computed locally in your browser
- Only the fingerprint is stored on-chain — never the document
- Proves exact content existed at a specific time
- Connected to your wallet address for ownership
Verify Anytime
Anyone with the original file can re-hash it and compare against the blockchain record. If the hashes match, the file is proven to be identical to what was registered.
- Public verification — no account needed
- Hash comparison happens in the browser
- Permanent record on the blockchain
- Shareable proof links for any registered analysis
Privacy by Design
Your documents never leave your control. Here's how the system protects your data.
Client-Side Hashing
SHA-256 fingerprints are generated in your browser. The hash never depends on our servers.
Zero On-Chain Files
Only the 64-character hash is stored on the blockchain. Your actual documents are never uploaded to the chain.
Your Keys, Your Proofs
Proofs are tied to your wallet address. Only you can register proofs from your wallet.
