SnapShell
Inspiration
When we started brainstorming, we thought about everyday problems people deal with. Email quickly came up as one of the biggest pain points. Most people read their emails, type out a response, and then use some AI tool to polish it. Tools like that already exist, so we asked ourselves: what would make ours different? That’s when the idea of sorting emails by their actual content came up, instead of just date or sender. Combining that with automatic summaries and draft replies, we realized we had something new and useful.
What it does
SnapShell makes handling emails easier. It looks at the content of each email and gives it a priority level of high, medium, or low. It then generates a quick summary of the email so you don’t have to read through everything, and finally, it can draft a reply for you in the tone you choose—whether that’s professional, empathetic, or urgent.
How we built it
We built SnapShell using Google’s ADK and created four agents with the Gemini 2.5 Flash model. The manager agent oversees everything, while the sort agent handles prioritization, the summarize agent gives short summaries, and the draft agent writes responses. On the front end we used HTML, CSS, and JavaScript, while the agents ran in Python. We connected it all through the Gmail API, which lets the extension securely access emails once the user authenticates.
Challenges we ran into
The hardest part was definitely the back end. Connecting the front end to the AI agents was tricky, and we ran into bug after bug. We even had to scrap everything and start over a few times before we finally got it working.
Accomplishments that we're proud of
We’re really proud that in just 36 hours we managed to build a working AI extension from scratch. For us, this was not just about making something functional but also about learning how to use Google’s ADK in a real project.
What we learned
We learned a lot about how the ADK works and how powerful it can be when it comes to building multi-agent systems. It was our first real experience using it, and it opened our eyes to a lot of possibilities.
What's next for SnapShell Email Assistant
Right now SnapShell is just a demo that works on Chrome with Gmail. In the future, we’d love to improve the accuracy of the agents and expand it to other platforms like Outlook and Edge so more people can use it.
