Inspiration
In today’s fast-paced digital world, content creators, developers, and students constantly switch between apps to write, translate, proofread, or summarize information. This is inefficient and costly — especially in areas with poor internet access.
Neo Blaster was inspired by the idea of bringing an “AI workstation” directly into the browser — private, offline, and free of server limits — using Chrome’s Built-in Gemini Nano capabilities.
What it does
Neo Blaster is an all-in-one AI productivity hub built directly into Chrome as a browser extension.
It integrates multiple Chrome Built-in AI APIs to help users:
💭 Prompt API: Generate creative ideas, code snippets, and multimodal responses from text, images, or audio.
🔤 Proofreader API: Automatically correct grammar and spelling errors.
📄 Summarizer API: Turn long articles or research papers into concise summaries.
🌐 Translator API: Translate web content into any preferred language instantly.
✏️ Writer API: Draft emails, essays, or posts with engaging tone and structure.
🖊️ Rewriter API: Suggest stylistic improvements and variations for better clarity or creativity.
✅ All features work client-side, ensuring:
No data leaves the device.
Works offline.
Instant performance without latency.
How we built it
Frontend: Built using HTML, CSS, and JavaScript, styled with Tailwind CSS for a clean, responsive UI.
Backend: Fully client-side — no traditional backend server required.
Integration:
Used Prompt, Writer, and Proofreader APIs locally.
Implemented Gemini Nano for multimodal support (image + audio input).
Integrated Firebase AI Logic for hybrid cloud fallback when needed.
UX: A floating Chrome popup for writing, translating, and summarizing any selected text on a webpage.
Challenges we ran into
Combining multiple APIs (e.g., Proofreader + Translator) in a seamless workflow.
Managing local caching for offline AI features.
Creating a lightweight UI overlay that doesn’t block the webpage.
Ensuring consistent AI performance across offline and hybrid modes.
Accomplishments that we're proud of
Achieved a 100% client-side AI workflow, ensuring privacy and speed.
Built a multi-purpose Chrome extension usable even on weak networks.
Designed a modular, open architecture for easy extension by other developers.
Seamlessly integrated Gemini Nano APIs for multimodal intelligence.
What we learned
The power of on-device AI through Chrome’s Gemini Nano.
How to design offline-first AI tools with Firebase hybrid fallback.
Improved understanding of user-centric AI UX design.
Optimized prompt chaining across multiple AI APIs.
