AI Source Evaluator for Students
Leila is a 9th-grader writing a paper on social media regulation. She found a statistics-heavy article that supports her argument perfectly. Her teacher tells her the source is not credible, but Leila does not know how to tell the difference between a credible source and a convincing-looking one. The AI Source Evaluator evaluates the article using the SIFT method, identifies three red flags, gives it a credibility score of 4 out of 10 with an explanation, and suggests two stronger corroborating sources she can use instead.
The AI Source Evaluator is one of several AI tools built into OpenEduCat. It teaches lateral reading, the skill professional fact-checkers use, as a habit, not just a one-off check.
How It Works
From URL to credibility assessment in four steps.
Enter a URL or source description
The student enters a URL, a source description (title, author, publication, and date), or a quote they found and wants to verify. The AI uses the source information to begin the SIFT evaluation: Stop (pause before accepting the claim), Investigate the source (who is behind this?), Find better coverage (what do other sources say about this claim?), and Trace claims (where did this claim originally come from?).
AI evaluates authority, accuracy, currency, purpose, and bias
The AI evaluates five dimensions of source credibility. Authority: is the author or organization a recognized expert in this field? Accuracy: are the claims supported by evidence, and are sources cited? Currency: is the information recent enough to be relevant? Purpose: is this trying to inform, persuade, sell, or entertain? Bias: what perspective does the author or publication have, and how does it shape the content?
Receive a credibility score with red flags and explanation
The AI produces a credibility score from 1 to 10 with a brief explanation of the rating. Red flags are listed explicitly, "No author named," "Publication has a documented ideological agenda," "Statistic cited with no original study linked," "Domain designed to mimic a credible source." The explanation teaches the student how to read the red flags, not just what they are.
Get suggestions for corroborating sources
For any claim the student wants to use in their research, the AI suggests specific types of corroborating sources and search terms to find them. A student relying on a think tank report might be directed to the peer-reviewed studies the report summarizes. A student using a news article might be directed to the government data set the journalist cited. Corroboration is the key skill that separates reliable research from Wikipedia-level citation chains.
The Source Credibility Problem
Stanford researchers studying source evaluation found that even professors and PhD students were significantly outperformed by professional fact-checkers at identifying credible sources, not because of intelligence, but because fact-checkers use lateral reading (checking what others say about a source) while academics tend to read sources carefully and try to evaluate them from the inside. Students who learn lateral reading skills can evaluate sources more accurately and more quickly than those who rely on reading-based judgment alone.
The AI Source Evaluator teaches lateral reading as the primary strategy, not as a supplementary check.

What the Source Evaluator Includes
Every evaluation teaches the student how to make the same judgment independently next time.
SIFT Method Framework
SIFT (Stop, Investigate the source, Find better coverage, Trace claims) is the lateral reading framework developed at Stanford and used by professional fact-checkers. The AI evaluates every source through all four steps and explains what each step revealed. Students who learn SIFT develop a transferable habit of pausing before accepting claims, which is one of the most important information literacy skills in a high-misinformation environment.
Credibility Score with Explanation
The 1-10 credibility score is not a black box, the AI explains the reasoning behind each dimension of the rating. A score of 6 means the source is worth reading but should be corroborated. A score of 3 means significant red flags are present and the student should find a different source. The explanation teaches the student to make the same judgment independently next time.
Red Flag Identification
The AI explicitly lists red flags it finds in the source: unnamed authors, sensationalist headline language, missing citations for specific statistics, domain names designed to look credible, known bias ratings from media watchdog organizations, publication dates that predate evidence they claim to report, and claims that cannot be traced to an original study. Red flag identification is more useful than a vague "use caution" warning.
Lateral Reading Guidance
Lateral reading means leaving a source immediately to look at what other sources say about it, rather than reading the source itself more carefully. Professional fact-checkers use lateral reading because it is faster and more reliable than trying to evaluate a source from the inside. The AI teaches this skill by explicitly directing the student to check the source's reputation on independent platforms before reading its content.
Corroborating Source Suggestions
After evaluating a source, the AI suggests how to corroborate its key claims: which databases to search, what search terms to use, and what type of source (peer-reviewed study, government data, independent investigation) would provide the strongest corroboration. Corroboration is not just about finding agreement, the AI explains how to determine whether multiple sources agree because they all reference the same original study or because independent evidence supports the claim.
Bias and Purpose Analysis
Every source has a purpose and a perspective. A pharmaceutical company's press release about a drug study is not the same as an independent clinical trial. A think tank's policy report reflects its funders' priorities. The AI identifies the publisher's known perspective, funding sources where documented, and the rhetorical purpose of the specific piece (informing, persuading, advocating, or selling) so the student knows how to read the source critically.
Who Uses the Source Evaluator
High school students writing research papers use the tool before citing any source they found through a general web search. The tool is fastest for exactly the situation where students are most likely to make a credibility mistake, when they have found a source that confirms their argument and want to use it without checking further.
Social studies and current events teachers use the tool as a classroom media literacy exercise. Students evaluate the same set of sources and compare their scores and reasoning. The discussion about why two students rated the same source differently often produces the deepest media literacy learning.
Journalism and communications students use the tool as part of reporting workflows. Before citing a statistic or source in a piece, the student runs it through the evaluator and uses the corroboration suggestions to find the original study or data set behind the claim.
Librarians and information literacy instructors use the tool as a demonstration platform when teaching database research and source evaluation units. The explainability of the SIFT evaluation makes it suitable for classroom instruction, not just individual use.
