Hive's AI-generated Content Detection model allows you to quickly scan any image, video, text, or audio file on the web to determine whether or not it was made by AI. Use Hive AI Detector easily while browsing with three different ways to scan content — right-clicking it right on the webpage, pasting it into our text box, or uploading a file. This free tool displays the likelihood that something is AI-generated. For image and video inputs, our Detector also predicts what generative engine was used to create it. Our free AI Content Detection has been praised by The New York Times, The Wall Street Journal, and PCWorld, as well as by various artists and educators worldwide. It can be used to check for plagiarism, catch misinformation, and more — no login necessary. Our detector uses AI itself to detect AI-generated content. With machine learning, we're able to spot otherwise imperceptible differences between what's human-made and what's AI-generated, beyond style, word choice, and number of fingers. We trained our model on millions of examples of both AI-generated and human-made content, and we regularly update it to perform well on the newest versions of Midjourney, ChatGPT, etc. To use the extension: From this page, click "Add to Chrome" Click on the puzzle piece icon to the right of your search bar and pin Hive AI Detector to the extensions menu To scan content, either right-click it directly on a webpage or click the Hive logo to enter content via text box or file upload View your result!
Fake news debunker InVID WeVerify VeraAI
InVID WeVerify VeraAI extension This plugin has been designed as a verification “Swiss army knife” helping journalists, fact-checkers, and human rights defenders to save time and be more efficient in their fact-checking and debunking tasks on social networks especially when verifying videos and images. This browser extension was enriched with new tools, developed within the Horizon EU research and innovation action vera.ai (2022-2025; https://veraai.eu/). In 2021, the plugin won a US Paris Tech challenge first prize award granted by the US Department Global Engagement Center (GEC). For the Poynter Institute, home of the International Fact-Checking Network (IFCN), it is "one of the most powerful tools for spotting misinformation online". This toolbox allows you to quickly get contextual information on Facebook and Twitter images and videos, as well as on Youtube videos, to perform reverse image search on several engines, to query the new Database of Known Fakes (DBKF), to fragment videos from various platforms (Facebook, Instagram, Youtube, Twitter, Daily Motion) into keyframes, to enhance and explore keyframes and images through a magnifying lens, to query Twitter more efficiently through time intervals and through a new Social Network Analysis module, to read video and image metadata, to check the video copyrights, to quickly search for fact checks or cross-network queries, and to apply a new enhanced forensic toolbox on images suspected of being manipulated. Another new forensic module, CheckGIF made in the EnVisu4 IFCN project, allows you to create a GIF between a manipulated image and an original one to better reveal the manipulation. New beta tools, for registered users, include a synthetic image detector from vera.ai project and an audio voice cloning detector provided by the US company Hiya.com after acquisition of the Spanish startup Loccus. An assistant feature will help you to find which tool can be used to support your verification work. The plugin is currently provided in English, French, Spanish, Greek, Arabic, Italian, German, Japanese, Portuguese (Brazil) and Hungarian language. A demo and a classroom section provide examples of manipulated images or videos together with explanations and media literacy tools and tips about the information verification process, for teachers and scholars. New tools developed in the IFCN DisinfoArchiving project (2024-2025) allow you (upon registration) to better archive traces of disinformation using the WACZ format (Web Archive Collection Zipped). A feedback button is available directly in the interface. Thanks to use it to report any bug, any issue (providing the link of the media to be checked), or any improvement suggestion, in this way. We welcome and need your feedback. Thank you. The plugin respects your privacy and no personal data is recorded. Caching of content is used by various partner tools for about one day to significantly improve UX. We use Matomo to better understand usage but you can opt out if you wish so (from the checkbox at the bottom of the About page). Some features (Twitter SNA, CheckGIF, GIF export on forensic toolkit) are reserved to fact-checkers, journalists and researchers due to the high demanding computer power needed and to avoid misuse. All versions of the plugin has been developed so far by AFP Medialab R&D through three EU-funded research projects and underlying web services provided by scientific partners. It was initially launched in July 2017 during the InVID European project, a EU Horizon 2020 innovation action (grant agreement 687786; https://www.invid-project.eu ; @InVID_EU). Then, it was enhanced with more tools during the EU Horizon 2020 WeVerify project (grant agreement 825297; https://weverify.eu/ @WeVerify). Currently, the plugin is part of the Horizon vera.ai project (Grant Agreement 101070093; https://twitter.com/veraai_eu) aiming to use artificial intelligence versus disinformation. Existing tools using AI will be enhanced and new tools will be co-created with end-users.
