01 / EVIDENCE CHAINS
Every claim has a trail.
Connect conclusions to exact passages and source locations. Keep the original evidence close enough to inspect, challenge and revisit.
THE TRUST LAYER FOR AI
Give your AI answers that people can inspect, reasoning they can verify, and evidence they can follow.
Evidence chains and logic verification for AI companies and developer teams.
Your models. Your product. A stronger foundation of trust.

A FOUNDATION FOR RELIABLE AI
Connect what your AI says to the evidence and logic that support it.
A path from an answer to its sources, from a conclusion to its premises, and from a question to the evidence still needed.
01 / EVIDENCE CHAINS
Connect conclusions to exact passages and source locations. Keep the original evidence close enough to inspect, challenge and revisit.
02 / LOGIC VERIFICATION
Make the path from facts to conclusions explicit. Derive results through rules, then check the proof independently of the process that produced it.
03 / TARGETED DISCOVERY
Work backwards from a question to its missing premises. Direct the next read towards evidence that could change the answer, then revisit the reasoning.
04 / REUSABLE KNOWLEDGE
Bring evidence, confirmed facts and reviewed rules into a reusable knowledge layer. Preserve their dependencies so conclusions can be checked as information changes.
FOLLOW THE REASONING
An AI agent wants to approve a refund. Follow the evidence to see what supports the decision—and what can change it.
Try the example. Add the missing evidence, then introduce an exception.

FOR AI COMPANIES
Make verification part of the experience you deliver. We work with your team to connect evidence and reasoning checks to the workflows that matter.
YOUR PRODUCT
THE TRUST LAYER
BACK TO YOUR PRODUCT
A shared verification approach across models, retrieval systems and agent workflows.
Let users follow an answer all the way to the passage that supports it.
Expose the rules, conditions and exceptions behind a proposed action.
Connect findings to input values, calculations and the assumptions behind them.
RESEARCH FOR THE LONG TERM
CitProof is an AI trust research and technology company. We study how AI can justify its answers, test its reasoning and discover the evidence it still needs.
Our purpose is enduring: make trust a capability that AI products can build on. We turn that research into evidence and verification services for the teams creating them.
An answer should carry a path to what supports it.
New ideas become useful knowledge when their evidence and reasoning can be examined.
Retain the facts, rules and proof that make the next answer stronger.
WORK WITH CITPROOF
Bring us the part of your AI product where trust matters most. Build from a concrete question to an integration your team can evaluate.
A technical collaboration shaped around your product, data and users.
Connect source evidence, reasoning checks and reviewable results to your AI workflow.
Build representative cases and examine unsupported claims, reasoning failures and the effort needed to review an answer.
Explore evidence discovery, verifiable reasoning and reusable knowledge with us.
Choose the question, evidence and outcome that matter.
Connect a focused example and test it against your cases.
Shape the verification experience around your product.
AI companies and developer teams building assistants, agents, analytical tools and knowledge products. We help them add evidence and reasoning verification to the AI experiences they deliver.
A citation points to a source. An evidence chain connects a specific claim to its exact supporting content, the facts used in a derivation and the rules that lead to a conclusion. This makes the path inspectable and the relevant checks repeatable.
It makes conditions, dependencies and exceptions explicit. Our approach combines ASP-based derivation with independent proof checking, and uses goal-driven evidence discovery to identify which missing premises matter next.
Start with a technical conversation about one workflow. Bring representative inputs, outputs and examples of where trust breaks down. Together we define the checks, evaluation cases and integration scope.
BUILD WITH US
From the first source to the final answer, give your AI product a foundation that people can examine.
