Echo | Devpost

Inspiration

I wanted a tool to help people communicate more effectively and avoid hurting relationships with misinterpreted messages.

What it does

Echo analyzes your messages in real time, detects tone and emotion, predicts how your words will be received, and suggests better ways to phrase them, which in result will saveyour connections.

How we built it

I made a Chrome extension using JavaScript and CSS, with AI models accessed via OpenRouter. It uses real-time message analysis, emoji popups, audio cues, and a click-to-copy suggestions panel. It looks at your history with the person, and based on that, creates a relationship score using an alogrithm and based on that, it will give you recommendations on how to rephrase your msg better and how the person might perceive it.

Challenges we ran into

Fixing the security requirements in order for the program to work with WhatsApp and Discord took the longest.

Accomplishments that we're proud of

I was able to give a real time relationship score using a custom algorithm, which individuall is personalized for each DM you have. Also, making it seamlessly work with two different social media platforms is very hard.

What we learned

I learned how to make Chrome extensions and how to use context based ai recomendations. Also learned how to connect your apps to real social media applications.
