Yes, minor variations may occur. The Medifact engine relies on the Medifact AI Engine (generative AI engine) to dynamically create search keywords and evaluate clinical papers in real-time. Since LLMs operate probabilistically, minor score adjustments are normal, but classifications (e.g., Verified vs. Contradicted) rarely flip. A single run is sufficient for general reference.

This occurs when traffic surges and exceeds the rate limits of the backend AI cloud infrastructure. To prevent service disruption, the system activates a fallback mode, displaying structured mock templates. Waiting about a minute before trying again will resolve the rate limit and produce a real-time analysis.

Upon registration, you instantly receive 10 welcome credits. Registered users also get their verification history permanently saved to their account. Guests are limited to 3 trial checkings per browser session, which are lost when the browser cache is cleared.

You can explore various credit boosters on our Pricing page. Payments are handled via secure channels including PayPal and major credit cards, with purchased credits applied immediately.

Licensed physicians and specialists can submit their credentials via the account dashboard. Once verified by admins, they obtain the 'MD Specialist' badge and can add or update clinical opinions on AI report pages, helping the public get higher quality medical guidance. Medifact supports 1:N multiple opinions. To prevent abuse, initial opinion submissions do not grant automated credits, but for every 3 likes (recommendations) received on your opinion from other users, 1 extra credit and reputation points will be continuously rewarded. Participating in paid review requests returns 70% of the review fee back to the specialist. Once your Reputation Score reaches 50 or above, your clinic name and reservation link will be displayed on the report page as a branding benefit.

Medifact sets itself apart from traditional fact-checking initiatives through its real-time automation, claim extraction, and B2B extensibility.

1. Real-Time RAG Verification: While expert-led networks (like Health Feedback) require days or weeks for a single review, Medifact uses retrieval-augmented generation to search PubMed and clinical guidelines, returning scores and reliability grades in seconds.
2. Automated Claim Extraction: Users don't need to write pre-formulated questions. Simply inputting an article URL or text allows the AI to automatically identify and verify specific medical claims.
3. Physician-Assisted Hybrid System: Medifact combines AI efficiency with human expertise. Licensed physicians (MD Specialists) can review AI-generated reports and write clinical notes.
4. B2B API Integration: Unlike public dashboard services, Medifact provides a production-grade API endpoint (/api/v1/b2b/verify) with options like Zero-Data Retention for healthcare portals, community apps, and advertising filters.

Yes, there are. If all extracted medical claims are determined as 'inconclusive' (judgment deferred), the overall trust score will be displayed as N/A (Not Available).

This occurs when no matching clinical studies or academic papers are found in the databases, or when all search results fail to meet the relevance score threshold (T=60) and are filtered out. This is a safeguard to honestly represent the absence of reliable evidence rather than generating a speculative score.

The Medical Trust Score reflects the overall safety and clinical agreement of the verified evidence. Meanwhile, the Insufficient Evidence Rate indicates the percentage of claims that were classified as 'Inconclusive' (judgment deferred) due to a lack of matching clinical studies or literature.

For instance, a score of 97 with an insufficient evidence rate of 50% means that while half of the claims lack scientific evidence to verify, the remaining half that could be verified are highly reliable and medically safe (97 pts). Therefore, if a report has a high score but also a high insufficient evidence rate, you should still be cautious as it indicates that many claims in the source text remain scientifically unproven.

The premium AI Text-to-Speech (TTS) feature is exclusive to Paid Plan subscribers and Administrators. If you are using the service as a guest (non-member) or are logged into a Free Plan account, the voice playback feature will be locked. Subscribing to a paid plan will grant unlimited access to premium AI voice readouts of both summary reports and verification logic.

When a user submits a report (privacy violation, spam/advertisement, misinformation, or other reasons) using the [Report] button on a public fact-check page, the system immediately registers the report details and increments the cumulative report count for that post.

The submitted report and cumulative count are instantly routed to administrators and verified medical experts (MD Specialists) for review. If a post is verified to contain inappropriate content, it is manually marked as hidden (Blind/hidden_at applied). Once hidden, the post is immediately excluded from all public lists and detail views, preventing any further public access.

Yes, they are saved. Once a fact-check is performed, the result is saved and accessible via a unique URL.

1. Registered Users: All past verification reports are permanently saved to your account and can be accessed anytime from [My History].
2. Guests (Non-members): Results remain accessible during your browser session based on local session cookies. (Note: Clearing browser cookies or switching devices may prevent access to past guest verifications.)
3. Public Access & Caching: If a report is set to public or if another user submits the exact same claim, the existing result page will be reused to provide instant answers.

⚠️ Note: When a report is updated via 'Refresh Evidence' or physician review, the main header always displays the latest version to ensure clinical safety. Historical score changes and summary logs can be audited in the [Revision History] timeline at the bottom of the page. (See Q14 for details)

Yes, the score may change. This is a normal verification outcome reflecting real-time medical research updates.

1. Cause: Clicking 'Refresh Evidence' re-searches medical databases (PubMed, KCI, etc.) from scratch. If newly published clinical trials, large-scale meta-analyses, or official safety advisories are retrieved, the score is re-evaluated to incorporate this evidence.
2. Interpretation: A score adjustment does not imply the previous report was an error. Rather, it indicates that advanced medical safety standards—evaluating human clinical efficacy and side-effect risks beyond basic biological mechanisms—have been applied. Always rely on the most recently refreshed report.

Medifact ensures that users rely exclusively on the most current and medically safe consensus in the main report, while maintaining full transparency (Audit Trail) through revision tracking.

1. Latest Version Guarantee: As medical consensus evolves, the primary report view at the top of the page always displays the most recently updated version (vCurrent) to prevent reliance on outdated findings.
2. Revision History Timeline: Detailed logs of every iteration (Version 1, Version 2...)—including initial AI drafts, specialist revisions, and evidence refreshes—are accessible in the [Revision History] timeline at the bottom of the page. This timeline transparently displays score adjustments, key diffs, revision causes, and summary breakdowns.
