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) ## DeepL DeepL is a specialist Language AI company widely recognized by professional translators, localization managers, and multinational enterprises for delivering more natural, idiomatic translations than general-purpose search translators or raw foundational LLMs. Headquartered in Cologne, Germany, DeepL trains proprietary neural networks and specialized language models tuned specifically for cross-lingual nuance, register, and domain accuracy across more than 30 languages. Over 200,000 businesses globally rely on DeepL to handle sensitive legal, technical, financial, and marketing communications.

Through its Customization Hub, teams enforce corporate terminology using Shared Glossaries, Translation Memory, and Shared Style Rule Lists, while interactive Clarify prompts resolve source-text ambiguities.
