The extension lives on Old Reddit and adds a "Validate Claim" button to every comment that contains a link. Clicking it starts a three-step analysis: the tool extracts each claim the comment makes, pulls the content from the linked source, and then judges whether the source substantiates each claim. The extraction and verification steps are handled by instruction fine-tuned large language models. The project is explicitly positioned as a companion against the erosion of trust online, and the developer is upfront about the irony of using generative AI to police generative-AI-era misinformation. It is an open-source codebase in active development, with a published roadmap covering multi-source comments, context from nearby comments, support for Reddit posts (not just comments), and expansion to other platforms such as Twitter and Wikipedia. The extension is free to use and currently relies on the developer's own API keys (Groq is used for speed), so heavy use may be throttled. There is no paid tier; the developer asks for contributors and accepts optional donations. Because it only runs on Old Reddit's classic layout and on comments containing links, it is a focused utility rather than a general-purpose fact-checking platform. **Pricing & Plans:** Completely free. The developer runs it on personal API keys for now and accepts optional donations via Ko-fi; there is no paid plan. - **One-click claim validation:** A Validate Claim button appears on Old Reddit comments that contain links, so verification is one click away instead of a separate research session. - **Claim extraction with LLMs:** Instruction fine-tuned models break a comment down into the discrete factual claims the author is implicitly or explicitly asserting. - **Source-grounded checking:** The tool fetches the linked source and evaluates each claim against it, showing where the citation does and does not hold up. - **Open-source and openly developed:** The codebase is public and the roadmap is shared, covering multi-source comments, Reddit posts, Twitter, and Wikipedia support. - **No data selling:** The developer declares that collected data is not sold to third parties or used outside the extension's core functionality. **Strengths:** Free and open source with a public roadmap; Very focused workflow: one button, clear verdict on citation quality; Explicit privacy stance: data is not sold or repurposed; Uses fast inference providers so results come back quickly **Limitations:** Only works on the classic Old Reddit interface; Limited to comments that contain a link; other claims are not checked; Relies on the developer's personal API keys, so availability and speed are not guaranteed; Zero user ratings and no recent version updates [Profile (Markdown)](https://openaitools.app/tool/claimvalidator.md) ## Truth Keeper Truth Keeper is a compact Chrome extension built around one job: give you a fast second opinion on whether a claim, paragraph, or article is credible. You feed text into the extension, an LLM-backed pipeline examines it, and the result comes back as a true-or-false label with an accuracy percentage so you can see how confident the assessment is. The extension is deliberately minimal. There is no dashboard, no team workspace, and no long onboarding — it installs from the Chrome Web Store, sits in your toolbar, and works whenever you want to sanity-check something you are reading. The developer states that the extension does not collect or use your data, which matters for people who paste sensitive internal or personal text. Because the verdicts come from a general-purpose language model, Truth Keeper is best treated as a screening aid that flags suspicious claims for further checking, not as an authoritative referee. Users who need sourced evidence should combine it with a fact-checking service that cites references. **Pricing & Plans:** Free to install from the Chrome Web Store; no paid tiers are advertised. - **True-or-false verdicts:** Submit any block of text and receive a clear true or false label back in the browser. - **Accuracy percentage:** Each verdict arrives with a confidence score so you can judge how decisive the model was. - **LLM-backed analysis:** Uses advanced large language models rather than a static keyword blocklist to reason about claims. - **In-browser convenience:** Lives in the Chrome toolbar as a small 146 KB extension, so checks happen without leaving the page. - **No data collection declared:** The developer states the extension does not collect or sell user data. **Strengths:** Free with no account or signup required; Extremely small footprint and simple interface; Returns both a verdict and a numeric confidence level; Developer declares no data collection or resale **Limitations:** No cited sources or evidence trail behind verdicts; Last updated in 2024 with a very small user base; LLM verdicts on factual claims can be wrong or overconfident [Profile (Markdown)](https://openaitools.app/tool/truth-keeper.md) ## Frequently Asked Questions ### How do ClaimValidator and Truth Keeper compare in monthly traffic?
