Private Document Intelligence: Your Documents Never Leave Your Control
We're built different. Because your contracts, agreements, and compliance documents should never train someone else's models.
Every document review tool has a dirty secret.
Most automated document review tools send your contracts, agreements, and financial documents to shared cloud APIs. Your lease terms train their models. Your deal clauses improve their product. Your confidential data flows through infrastructure you don't control. Calisto Assure operates on a fundamentally different principle: your documents are processed by intelligence that only you control.
Zero Training Exposure
Documents processed through Calisto are never used to train external models. Not ours, not Microsoft's, not anyone's. Your purchase agreements, talent contracts, and compliance documents remain exclusively yours.
Three Privacy Tiers
Choose your level of isolation. Standard uses Calisto's enterprise Azure instance. Dedicated gives you your own isolated compute resource. BYOB means documents never even touch our servers.
Enterprise Compliance Built In
SOC 2, HIPAA, GDPR, ISO 27001 compliance covered by Azure's enterprise boundary. Not an add-on. Not a premium feature. The default architecture for every customer.
Two intelligence layers. Both private. Both under your control.
Calisto Assure uses a hybrid architecture: Azure Document Intelligence extracts structured data, then Azure OpenAI analyzes it against your vertical-specific templates. Both layers respect your privacy tier.
Layer 1: Structured Extraction
Azure Document Intelligence extracts parties, dates, clauses, amounts, signatures, and tables from your documents. Pre-built models for contracts, invoices, and insurance certificates. Custom models available for industry-specific formats.
Layer 2: Intelligent Analysis
Azure OpenAI reviews extracted content against your templates. Flags missing clauses, unusual terms, compliance gaps. Provides plain-language explanations and suggested actions. Scores document completeness from 0 to 100.
Standard Tier: Enterprise Isolation
Your documents are processed through Calisto's Azure instance with per-tenant data isolation. Never used for model training. Never shared with other customers. Covered by Azure's full enterprise compliance stack.
Dedicated Tier: Your Own Compute Resource
Enterprise customers get their own isolated Azure OpenAI resource. No other customer touches your model instance. Same Calisto experience, completely dedicated compute. The privacy upgrade that costs you nothing in functionality.
BYOB: Maximum Control
Bring your own Azure OpenAI endpoint. Bring your own Document Intelligence instance. Documents flow from your browser to your Azure tenant. Calisto never sees the content. We only store the metadata and flags.
Human-in-the-Loop Review
The system flags concerns with severity levels and plain-language explanations. Your team accepts or rejects each flag with a complete audit trail. Automated review is a second set of eyes, not a decision-maker. Every resolution is tracked, timestamped, and attributed.
Every industry handles sensitive documents. None should expose them.
From real estate disclosures to HIPAA consent forms, every vertical has documents that carry real financial and legal risk. Calisto Assure reviews them privately.
Real Estate Agents & Brokers
Purchase agreements, disclosures, and inspection reports reviewed by intelligence that never exposes your deal terms. Missing contingency clauses flagged before close. Disclosure completeness scored automatically. Client confidentiality maintained by architecture, not policy.
Result: Compliant closings with zero data exposure
Health & Wellness Practitioners
Patient intake forms, HIPAA consent documents, and treatment agreements reviewed within your HIPAA-compliant Azure boundary. Compliance gaps flagged before they become violations. Practitioner licenses verified against templates. No PHI ever leaves your control zone.
Result: HIPAA-compliant document review
Property Developers
Construction contracts, zoning permits, and environmental reports analyzed privately. The system flags missing required clauses, unusual liability terms, and permit compliance gaps. HOA documents reviewed against regional requirements. Sensitive development terms stay confidential.
Result: Faster closings with compliance assurance
Artists & Talent Management
Talent contracts, rider agreements, and performance licenses reviewed without exposing deal terms to shared infrastructure. Compensation structures stay private. Exclusivity clauses verified. Rider requirements cross-checked against venue capabilities. Your talent's data is never training data.
Result: Confidential talent deal management
Equipment Rental Operators
Rental agreements, damage waivers, and fleet insurance documents reviewed for completeness and compliance. Liability gaps flagged before the asset leaves the yard. Equipment warranties tracked against maintenance schedules. Insurance certificates verified against coverage requirements.
Result: Airtight rental documentation
Hotels & Short-Term Rentals
Franchise agreements, management contracts, and vendor agreements reviewed against your standards. The system knows the difference between a boutique hotel management agreement and a resort franchise contract. Guest agreements verified for regional compliance. Vendor terms cross-checked for consistency.
Result: Portfolio-wide document consistency
Privacy isn't a feature. It's the architecture.
Competitors bolt on privacy as an afterthought. Calisto's three-tier privacy model is the foundation, not the add-on.
ChatGPT / Public Cloud
Documents sent to shared API endpoints. Data may be used for model training. No per-tenant isolation. No compliance guarantees. No control over where your data goes or how it's used. Fine for a blog post. Reckless for a contract.
Enterprise Add-Ons
Privacy bolted on as a premium tier. Base product uses shared infrastructure. Compliance is a checkbox, not an architecture. BYOB usually means "bring your own budget" with complex integration. Privacy is the exception, not the rule.
Calisto Assure
Privacy is the default. Every tier is production-ready. Standard is already isolated and compliant. Dedicated and BYOB add deeper control. Your documents never train models. Your deal terms never leave your boundary. Privacy compounds, it doesn't cost extra.
From review to signature to audit trail. Provably private.
Calisto Assure doesn't just review documents privately. It connects to Deals, Proposals, and Sign to create a complete quality control pipeline where every step is auditable and every document is protected.
Deals Integration
A contract comes into Deals. Assure reviews it privately. Flags go to the deal assignee. Issues are resolved before close. The deal progresses with documented quality assurance at every step.
Proposals Integration
Before a proposal goes out, Assure verifies content against your templates. Missing service terms flagged. Compliance language verified. Your proposals are consistent, complete, and professionally reviewed.
Sign Integration
After signature, Assure performs post-execution compliance verification. SHA-256 cryptographic sealing ensures document integrity. Complete audit trail from initial review through final signature. Tamper-proof records for every transaction.
Vertical-Aware Templates
45 document types across 13 verticals. Each template knows what to look for: required clauses, prohibited terms, compliance rules. A real estate disclosure review flags different issues than a talent rider review. Your vertical, your rules.
