You can drop in a PDF, Word document, PowerPoint deck, Markdown or text file, paste a link, or point it at a YouTube video, then ask questions in natural language. Answers are grounded in your sources and come with clickable citations so you can verify anything straight from the original page. Beyond one-off Q&A, the platform supports folders and multi-file chats, so you can query a whole reading list at once and compare findings across documents. A side-by-side layout keeps the conversation and the document open together, while translation lets you read material in another language or ask questions in a language different from the source. The team has expanded the suite with an AI writer, AI detector, flashcards, slide generation, and a dedicated research mode. Access is browser-based and device-agnostic, with desktop and mobile apps available. The free tier covers a limited number of documents per day with no sign-up required for the core experience, while the paid Plus plan removes limits and unlocks advanced features. Enterprise-grade handling (SSL in transit, encrypted storage, SOC 2 Type II storage provider) is advertised, and users can delete their documents at any time. **Pricing & Plans:** Freemium. A free tier lets you analyze a limited number of documents per day, and the core chat experience works without creating an account.

Instead of scrolling through a 3,000-word article or sitting through a long YouTube video, you click the extension and ChatGPT distils the page into a compact set of bullet points or a short paragraph, so you can decide within seconds whether the content deserves your full attention. The extension goes beyond a single summary button. You can choose Short, Medium or Long output to match how much detail you need, highlight a dense paragraph and ask TLDR to explain it in plain language with metaphors, save the result as a branded PDF with the source title and link, or turn the summary into audio with male and female text-to-speech voices. A chat panel lets you ask follow-up questions about the summarized content without leaving the page. TLDR is free to start and installs from the Chrome Web Store as a small extension that hooks into your normal browsing flow. It is published by the team behind tldr-ai.io and has been listed on the store since 2023. **Pricing & Plans:** Free to install and use from the Chrome Web Store.
