Is Google Gemini trained on Google docs? One indie developer thinks so, after it told players about his unreleased game plans

That’s something one game developer is wondering after a player was able to learn unreleased information about their game from the AI — including specific details the dev claims were never shared outside of a private Google Doc.</p><p>According to the developer’s <a href="https://www.reddit.com/r/IndieDev/comments/1vfwuf5/a_player_found_out_the_actual_name_of_my_games/">Reddit post</a>, specifically Google’s AI knew the name of a character ‘Vantage Tripod’ before it had ever been released publicly — the most the fanbase knew was that there’s a ‘Tripod Fish’ character planned for the game, but not this exact name. It also seemed to be able to regurgitate accurate information related to unreleased mechanics that the developer says they had only written into GDocs the day before the player’s AI interaction.</p><p>The developer admitted Google’s AI made a few mistakes, but said that some details were scarily accurate in many ways — accurate enough that the developer is certain Google must have scrapped his private documents.</p><p>Google says Gemini can access Google Docs information, but only does so when given express permission — such as being asked to summarise a document — and it adds that even when it does go into your files, Gemini handles data transiently. That is, Google’s AI won’t retain anything.</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:970px;"><p class="vanilla-image-block" style="padding-top:56.19%;"><img id="Xm2Jbq3TPCd5KnXeQrmZQM" name="Google Docs" alt="Google Docs" src="https://cdn.mos.cms.futurecdn.net/Xm2Jbq3TPCd5KnXeQrmZQM.jpg" mos="" align="middle" fullscreen="" width="970" height="545" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="credit" itemprop="copyrightHolder">(Image credit: Google)</span></figcaption></figure><p>There are a couple of exceptions to this. If a Google Doc is accessible to ‘Anyone with the link’ and that link is posted publicly online (such as on a page or in a forum) Google could scrape it for training data. Alternatively, if you’ve allowed a third-party extension to scrape your Google Docs, it’s possible Gemini could get access to that data — indirectly seeing what’s in your docs.</p><p>If you were to type out info from your docs into Google Gemini, it would also learn about what you had written that way.</p><p>Despite Google’s promises, some aren’t entirely convinced. The thread I shared above (along with plenty of anti-AI and anti-Google subreddits) is full of people certain that Google has drained their digital files for all the data it can find. Privacy company <a href="https://proton.me/business/blog/google-docs-ai-scraping#:~:text=On%20Android%2C%20Google's%20Gemini%20app,access%20to%20your%20stored%20content.">Proton</a> has also published an article outlining details such as <a href="https://support.google.com/gemini/answer/13594961">Google’s privacy hub</a> not explicitly saying it <em>won’t</em> use your content for AI training.</p><h2 id="so-many-unknowns">So many unknowns</h2><p>I’ve reached out to Google with a request for comment about what has happened here (it has yet to get back to me), and while waiting for an answer I had an attempt at recreating the responses by prompting Gemini myself with no luck. It’s only reference to these details was the Reddit post information.</p><p>Later <a href="https://www.reddit.com/media?url=https%3A%2F%2Fcf.preview.redd.it%2Fa-player-found-out-the-actual-name-of-my-games-upcoming-v0-ie5r3wzh2ihh1.png%3Fwidth%3D699%26format%3Dpng%26auto%3Dwebp%26s%3Dd64e1a71a6c053a62ee4f42efff7b0e67ac2741b">screenshots shared by the developer</a> show the friend who got the AI to divulge the details originally also failed to recreate the “fluke.”</p><figure class="van-image-figure inline-layout" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:1184px;"><p class="vanilla-image-block" style="padding-top:56.25%;"><img id="cz7uBaDiAgNokpwpFSPPsS" name="Google Gemini AI.jpg" alt="Google Gemini AI" src="https://cdn.mos.cms.futurecdn.net/cz7uBaDiAgNokpwpFSPPsS.jpg" mos="" align="middle" fullscreen="" width="1184" height="666" attribution="" endorsement="" class="inline"></p></div></div><figcaption itemprop="caption description" class=" inline-layout"><span class="caption-text">What does it know? </span><span class="credit" itemprop="copyrightHolder">(Image credit: Google)</span></figcaption></figure><p>The whole situation is very weird and it’s impossible to tell exactly what has happened, based on the information available. While it certainly looks like Gemini has used information it shouldn’t have, it's equally possible that the developer has provided the AI or the friend with access to that information without realising — allowing Gemini to respond the way it did.</p><p>The AI could also have hallucinated the information in some way, or perhaps taken inspiration from previous prompts to inform its comments. Further, it’s worth noting that the only responses that would stand out are these two that get very close to the truth, the sea of incorrect guesses that the AI could have given wouldn’t bat an eyelid.</p><p>Regardless of what happened it’s another situation that reminds us to be careful with our personal info. Digitally storing personal data has its risks beyond possible AI scraping, and sharing data with an AI often means your private info won’t be private anymore.</p> </article> ]]>
