FAQ
Wait, how are you different from the competition?
We are building a multi-modal tool that can work with any type of input (think YouTube, podcasts, etc) but our real motivation comes from giving back to Planet Earth. We donate monthly to charities doing protection and restoration work through our charity earth.fm. Our app can rapidly summarize entire books, considering their full context, setting us apart in the market. Our QA system's quality is rigorously tested against benchmarks from companies like Google and institutions like Stanford University, ensuring accurate responses. We do all that while prioritizing your privacy, with safety systems to ensure that your documents and personal information stay private.
Is any of my personal information stored in the application?
Your data is safe with us! We store only the essentials: your documents and login information. Your privacy is paramount, and you have the option to manually delete your documents whenever you choose, and we have systems in place to ensure that no data stays stored in external databases.
How does this AI system work?
Our AI requires a brief preprocessing period for your documents, depending on their size. It then employs advanced Machine Learning algorithms to generate comprehensive summaries. You can start conversing with your documents even while the summaries are being generated. The AI matches your questions with all the relevant sections of the document to provide accurate responses based solely on the information found in the documents. Tested extensively for accuracy, our system supports all languages and responds in the language of your query.
What types of documents can I upload?
Our application supports a wide range of document types, including PDFs, EPUB books, website URLs and even YouTube videos. We are continuously expanding our capabilities to include even more document types.
Is my document data secure?
Document security is a top priority! We never access your documents, and they are securely stored on our encrypted databases. The data sent to the AI is protected and excluded from being used in external model training. We also ensure the deletion of this data from external databases like OpenAI’s on a weekly basis to maintain your privacy.
Can I delete my documents from the database?
You have full control over your documents. Manual deletion is possible at any time. Additionally, our system automatically deletes documents after one month for Playful tier subscribers and after six months for Dynamic tier subscribers. For Flagship tier subscribers, documents are stored indefinitely unless manually deleted.
Is there a limit to the size of the document I can upload?
While we accommodate large documents with any amount of pages, there are limits on the file sizes to ensure optimal performance for all users. These limits vary depending on your subscription plan: Playful: 35MB, Dynamic: 50MB, Flagship: 65MB.
