About This Tool
What is the Overton Window?
The Overton Window is a concept describing the range of policies and ideas considered acceptable in mainstream public discourse at any given time. Ideas inside the window are seen as "normal" or "reasonable," while ideas outside it are dismissed as radical, fringe, or unthinkable.
This tool is named after that concept because it shows you how topics are framed across mainstream and less-represented viewpoints, and makes the window itself visible. It does not create the window; it helps users study the window that already exists.
What This Tool Does
When you search a topic, this tool surfaces sources from across the ideological spectrum: left, center, right, and voices that are less represented in mainstream U.S. discourse. Each source is classified with a written explanation of why it was placed where it was.
The goal is not to tell you what to think. The goal is to show you the full landscape of how a topic is being discussed, by whom, and from what perspective.
Our Assumptions
Every tool that organizes information makes choices about how to organize it. We name ours:
- The left-to-right spectrum is useful but limited. It flattens complex positions into a single axis. We use it because it is widely understood, but we show its limitations.
- "Neutral" is itself a position. Sources that present themselves as nonpartisan still make choices about what to cover, who to quote, and what to treat as normal.
- Access to diverse media is essential to democracy. Paywalled sources are deprioritized because equitable access matters.
- Underrepresented voices are not an afterthought. Communities that fall outside mainstream discourse have perspectives that belong in any honest research process.
How Sources Are Classified
Each source is evaluated based on:
- Ownership and funding structures
- Whose interests are defended or challenged
- Whose voices are centered in the reporting
- What structural critiques are present or absent
- What assumptions are treated as normal or taken for granted
Representation, Extremism, and Safety
This tool is designed to increase viewpoint visibility, not to endorse every claim it surfaces. Some positions are less represented because of institutional bias, and others are marginalized for legitimate public safety reasons.
When our model detects potential violent extremism, the source is flagged with a clear warning. In reader view, flagged content is blurred by default and can be manually revealed by the user.
Explicit calls to violence are excluded in current-events/news results. In historical and scholarly modes, high-risk material is contextualized with warning labels instead of being silently removed. This keeps safety guardrails clear while preserving critical inquiry.
Who Built This
This tool was built by a high school US History teacher, grounded in critical pedagogy. It is designed for students, educators, and the general public.
Any proceeds beyond operating costs are donated to educational programs.
