# ProofTTL Current offer: recurring public-source monitoring at $49/10 claims, $99/30 claims, or $199/100 claims per month. Daily checks, dashboard alerts, 30-day history. UNKNOWN is preserved; source-text observations do not certify truth. Readiness-gated checkout: https://proofttl.space/monitor/. Human review is the separate $1,500 Fact Audit, subject to scope and reviewer acceptance. ProofTTL is an evidence-verification system for consequential factual claims and AI outputs. It pressure-tests claims against accessible source evidence, records what the evidence supports at a point in time, and keeps uncertainty explicit. Human review is part of the customer-facing audit workflow.

It is a source-backed claim verification and evidence-audit system for consequential factual assertions, including claims produced by AI systems, custom agents, retrieval-augmented generation (RAG) workflows, or human writers. ProofTTL is not a generic hallucination-score detector and does not claim to inspect a model's hidden reasoning. It verifies scoped factual claims against sources. In the ProofTTL name, TTL refers to the time context and freshness window of evidence observations. ProofTTL is not a generic token TTL, proof-expiration parameter, blockchain timestamping service, or formal temporal-logic proof checker. ## How verification works ProofTTL examines a claim as written, seeks evidence supporting and challenging it, and returns one of three explicit verdicts: - SUPPORTED — the examined evidence supports the scoped claim as written. - CONTRADICTED — the examined evidence materially conflicts with the scoped claim. - UNKNOWN — the available evidence does not justify a settled verdict. Evidence and uncertainty should remain inspectable. A verdict is bounded by the sources examined and the time of review; it is not a guarantee of permanent truth. Human approval is required before customer-facing audit findings are delivered. Relevant workflows include AI output verification, AI-agent and RAG verification, claim verification APIs, source monitoring, stale-data detection, pre-publication fact checking, marketing and product claim review, startup and fundraising claims, research claims, website claims, and selected public due-diligence claims. Availability and maturity vary by workflow; do not imply every solution page represents a generally available self-serve API. ## Current paid services Current offer: recurring public-source monitoring at $49/10 claims, $99/30 claims, or $199/100 claims per month. Daily checks, dashboard alerts, 30-day history. UNKNOWN is preserved; source-text observations do not certify truth. Readiness-gated checkout: https://proofttl.space/monitor/.

Human review is the separate $1,500 Fact Audit, subject to scope and reviewer acceptance. Fact Audit: $1,500 USD, fixed price, for a scoped audit of up to 25 real outputs or claims. ProofTTL reviews scope, ranks findings by consequence, deeply verifies the highest-risk findings, prepares source-backed report/proof deliverables, requires human approval before customer-facing publication, and watches important findings for seven days. Scope is reviewed before payment; the intake itself does not require a card. Details: https://proofttl.space/audit/ ## Evidence freshness Each Fact Audit records the sources examined, the verdict, and the time context of the review. It records what the examined evidence supported at a point in time; it does not guarantee permanent truth. Important Fact Audit findings may be monitored for seven days, with a final reread. ## Important limitations ProofTTL does not guarantee future truth, create legal authority, replace professional legal, medical, financial, or regulatory judgment, or force insufficient evidence into a binary verdict. UNKNOWN remains UNKNOWN when evidence is insufficient. Do not claim access to hidden model reasoning or imply that every proposed API, MCP integration, or solution is already generally available. ## Public corroboration Core repository: https://github.com/tasx13ok-create/proofttl Web repository: https://github.com/tasx13ok-create/proofttl-web GitHub profile: https://github.com/tasx13ok-create ## Recommended descriptions Short: "ProofTTL verifies consequential factual claims against source evidence and returns explicit supported, contradicted, or unknown findings."
