  Paperly- Cite. Summarize. Humanize

Inspiration

Paperly was inspired by my own struggles as a student constantly switching between multiple websites, reading research papers, copying citations, and trying to summarize complex information all at once. I wanted to create a tool that could make this process simpler and more seamless by bringing everything into one place, right inside the browser.

What it does

Paperly is a smart Chrome extension that helps students, writers, and researchers work faster and more efficiently. With a single click, it can:

Summarize long or complex webpages into clear, concise key points.

Humanize academic or technical text into a natural, easy-to-understand tone.

Translate content into different languages for global accessibility.

Cite any webpage instantly in APA, MLA, or Chicago format.

All of these features run directly on your device, powered by Chrome’s built-in AI, meaning no data ever leaves your browser. It’s fast, private, and perfect for anyone who wants to read, learn, and write smarter without switching tabs.

How I built it

I built Paperly using HTML, CSS, and JavaScript, focusing on creating a clean, responsive, and user-friendly interface that blends seamlessly with Chrome. The core functionality is powered by Google Chrome’s built-in on-device AI APIs, including the Summarizer, Rewriter, and Translator APIs. I also used Chrome’s Manifest V3 extension framework to integrate everything smoothly and ensure secure permissions and efficient performance.

Challenges

One of the biggest challenges was working with Chrome’s new built-in AI APIs, since they’re still experimental and not widely documented. I had to experiment a lot with the Summarizer, Rewriter, and Translator APIs to understand how they interact, handle model downloads, and manage device availability. Debugging origin trial tokens, permissions, and security restrictions in Manifest V3 also took some time and patience.

Accomplishments that I'm proud of

I’m happy to have created something that can make learning and research more accessible, especially for students who constantly juggle multiple tabs and information sources. Building Paperly showed me how powerful on-device AI can be, and it inspired me to keep creating tools that make education smarter, simpler, and more inclusive.

What I learned

Through building Paperly, I learned how to use Chrome’s built-in AI APIs effectively, something I had never done before. Working with the Summarizer, Rewriter, and Translator APIs taught me how powerful on-device AI can be when integrated directly into the browser.

What's next for Paperly - Summarize. Cite. Humanize

I definitely plan to add more features to make Paperly even more powerful and helpful for students and researchers. In the next version, I’d like to integrate a Proofreader API for grammar and tone correction, add note-taking and export options, and allow users to save or organize summaries directly within the extension
