FAQ - Frequently Asked Questions

Early-Detector.ai is an AI symptom checker that produces clinical accuracy for the user and engagement and conversion metrics for the buyer return on investment. It is what one could call a dual-value AI symptom checker widget.
​
The user engages in his conversation with the Early-Detector Widget, answers the questions, receives his results and then receives a printed report in pdf format of his session. Its accuracy is equivalent to other AI symtom checkers.
​
The buyer of the Widget, usually a health Website, observes a substantial improvement in several metrics on his Website, that range from lower, bounce rate, longer time-on-site, higher number of page views and conversions and improved return visits to the Website. This provides the buyer with an appreciable return on investment.

The Early-Detector AI makes no precise claim as to its accuarcy. Many different third-party testing methodologies are being used and a ranking of accuracy can be very dependent upon the methodology used. Early-Detector does claim though to achieve an 85% to 92% Top-3 diagnostic accuracy, performing on par with other AI symptom checkers. Several studies are available to certify such findings for the leading AI symptom checkers. It is nowadays accepted that AIs deliver slightly superior results than licensed physicians in text-only clinical vignettes comparative tests.
​
The Early-Detector claims to own several additional features leading to high level of accuracy:
- It doesn't wait for only the symptoms the user is aware of, but also searches further for symptoms the user is unaware of.
- It asks more symptom questions than competitors (30 to 60, against 10 to 30) to progressively eliminate diseases with a low probability of occurrence.
- It allows for a change of answer of a user, such as "do you have puffy ankles" changing from a "yes" answer to a "no" answer anytime, without disrupting the process.

AI symptom checkers create a lot of new interest on health and healthcare Websites.
 
- Users receive immediate responses about possible conditions and suggested next steps, which keeps them engaged rather than waiting for delayed consultations.
- Symptom checkers often include explanations and health advice, increasing users' knowledge and encouraging them to explore more content on the site.
-They offer a quick, accessible way for users to assess their health concerns anytime, increasing site visits and time spent on the platform.
- They provide accurate and helpful AI-driven assessments that can build trust in the site as a reliable healthcare resource.
- By guiding users on when to seek professional care or which services to use, symptom checkers can drive further engagement with the healthcare Website's offerings.
- They can gather anonymized data on user concerns and behaviors, enabling the site to tailor content and services better.
​
And overall, ​AI symptom checkers, and in particular Early-Detector 1.0, transform passive browsing into an interactive, informative, and supportive experience, which significantly enhances user engagement on healthcare websites.

Evidently, we are going to promote Early-Detector first. It offers AI symptom checker widgets designed to be embedded into healthcare websites, aiming to enhance user engagement and SEO. It is built with those specific intentions of marketing and trust, in addition to providing a high level of precision in the health assessment.
 
For the competitors, we cannot make any particular claim. The competing symptom checkers Patient.info, NHS 111 Online, Isabel, Doctronic, Ubie, or Docus.ai likely have alternatively good precision in their health assessments and perhaps good marketing characteristics for their clients. But we know of no available information on the subject.

Early-Detector.ai acts as a high-intent engagement engine. Real-world data from our April 2026 relaunch showed that after integrating the widget, average session duration increased from 3m 23s to 12m 34s—a nearly 4x increase in user engagement.

By providing immediate, interactive value, the widget eliminates "information hunting" on other sites and keeps the user within your ecosystem. This drastically reduces bounce rates and primes the user for downstream conversions, such as booking a consultation or purchasing a health plan.

Yes. In a direct comparison study conducted on our own platform:

• Before Widget: 3m 23s average session.

• After Widget: 12m 34s average session.

This demonstrates that users find the diagnostic journey deeply engaging and are willing to spend significant time interacting with the AI to understand their health. For a website owner, this means 400% more time to present your brand, services, and call-to-actions to every visitor.

No. Early-Detector is a lightweight, asynchronous no-code widget. It loads after your primary content to ensure your SEO signals and page-speed scores remain optimal.

​

That is one of the reasons Early-Detector 1.0 is a good fit for most health and healthcare related Websites.
​

​
A few of our customers are visible on our clients page at www.early-detector-sales.com/clients.

The specific regulatory statuses of symptom checker are not published as a comprehensive list to our knowledge. You will need to conduct that search yourself and discover these clinically validated or certified symptom checkers.
​
From our company's perspective, Early-Detector.ai 1.0 does not have an FDA or CE marking yet. We have initiated our steps in that direction nevertheless. Our real and present certification is that the 2 patents have been granted. They are US Patent 7,149,756A and EU Patent EP 1284639-B1. 

Early-Detector AI is built on a Privacy-by-Design and Data Minimization framework. We do not collect or store Direct Identifiers such as names, email addresses, or phone numbers. The only data processed for the diagnostic logic is non-identifiable demographic data (age and gender).
Because we do not link health inputs to a user profile, the Early-Detector is considered fully GDPR compliant and a "safe" integration for healthcare providers, insurers, and pharmacies who require the highest standards of data sovereignty.

Evidently, we are the creators of the Early-Detector.ai 1.0 symptom checker. So we have the tendency to announce that our symptom checker is better. We claim this, given that it has the ability to ask many more questions than the competitors, such as 30 to 70 symptom questions (against less than half for the average of competitors). This has the quality of eliminating many potential diseases and giving thereby a more accurate result.
​
Early-Detector 1.0 also provides a host of marketing results and insights to the customer, which other symptom checker companies perhaps do not have.

Other symptom checker with a reputation of being accurate, you find Ada Health among the most accurate and widely-used options, NHS Symptoms A to Z, an authoritative, free resource directly from the UK's National Health Service and Symptomate as a self-service symptom checker created by doctors.

Besides all the marketing aspects for the Website, the pre-screening of a patient can be a gain of time for the physician in activity behind that Website. In addition, the physician may receive a report of the patient, if and when the patient forwards the results to him, whether in the form of a printout or an electronic file.

The only place to our knowledge with a patented technology for an AI symptom checker is here at at www.early-detector-sales.com.
The patents granted to and linked to Early-Detector 1.0 are US Patent 7,149,756A and EU Patent EP 1284639-B1. We have not found any other symptom checker with a patent, but perhaps are there some patents out there among competitors.

If the healthcare AI has structured their product and business correctly, you can get a free AI symptom checker to install on your Website. There are a few competitors in the market, such as Ubie, Docus.ai, Symptomate, Doctronic.ai, patient.info and Ada Health. You can have the Widget for an affordable monthly price on your Website though. That is what Early-Detector 1.0 does. Your Website pays a "Software-as-a-Service" monthly fee. But the usage is free for the end-user.

Yes. In accordance with the 2026 EU AI Act, the Early-Detector widget is clearly labeled as an Artificial Intelligence tool. It is designed to provide diagnostic support and risk stratification, not a final medical verdict, ensuring full transparency in the user-machine interaction.

Clinical validation of an AI symptom checker requires rigorous, peer-reviewed testing against real-world medical cases, demonstrating high diagnostic accuracy, safety, and generalizability across diverse populations, often benchmarked against expert physicians. The main labels of validation are FDA and CE markings. The duration of the process is 1 to 2 years.

Nevertheless, these studies must not be tested against simple physician reviewed vignettes, as such vignettes contain 6 to 15 symptoms in general. The physician is the weak spot in the whole testing process, as the reality shows that every disease has somewhere between 15 and 40 symptoms. Given that AIs are likely to be better than physicians, the real benchmark for testing are databases stripped of all errors, false-positives and false-negatives.

We don't know of any particular symptom checker immediately available for telemedicine. This includes telemedicine for mental health.

The team has decided that 2 different messages on the same Website are somehow confusing. The Website of www.Early-Detector.ai is the one hosting the technology of the Early Detector for the purpose of the user, in line with other competing Websites involved in the same activity. Its role is to reach out to individual users.
​
The Website www.Early-Detector-Sales.com is for the purpose of distributing the Early Detector Widget to customer Websites. Thereby, its message is for reaching out to corporate customers, essentially Websites. The communication and the marketing approach are quite different. 

No. Unlike general-purpose LLMs (like standard ChatGPT), Early-Detector.ai is a constrained diagnostic engine. It uses a patented reasoning framework that cross-references symptoms against a validated clinical database. It does not 'guess'; if a data point is missing, it asks clarifying questions—exactly like a licensed physician.
