SideLens: The Echo-Chamber Analyzer

Inspiration

I wanted to tackle one of the biggest silent problems on the internet today: echo chambers and hyper-polarized media. Scrolling through feeds filled with rage-bait and emotional vitriol gets exhausting, and I wanted to build a tool that helps people step back, see through the manipulation, and actually understand opposing perspectives.

What it does

SideLens is a sleek web application that takes angry, highly biased internet rants or articles and uses AI to instantly break them down into three objective analytical lenses:

Logic Flaw Detector: Exposes hidden emotional triggers and manipulative phrasing.
The Steelman: Generates the absolute strongest, most charitable version of the opposing argument.
Common-Ground Summary: Extracts a neutral summary that both sides could theoretically agree on.

How I built it

I built this project from a completely empty folder, leveraging a coding agent paired with structured planning to design, code, and polish the app in a single afternoon. I focused heavily on creating a high-end, cyberpunk-inspired editorial dashboard rather than settling for generic AI styling, ensuring clean typography, stark contrast, and smooth micro-interactions.

Challenges I ran into

Balancing the prompt instructions to ensure the AI generated distinct, sharp analytical lenses without sounding repetitive was a fun challenge. I also had to carefully structure the UI layout to display three dense blocks of text cleanly without cluttering the screen on smaller viewports.

Accomplishments that I'm proud of

I am proud of shipping a fully functioning, polished proof of concept entirely from scratch in just an afternoon, complete with professional planning docs (scope.md, prd.md, spec.md) and a stunning UI that genuinely stands out from typical hackathon submissions.

What I learned

I learned how crucial it is to define a tight, focused product scope before writing code. Using an AI-assisted workflow to handle the heavy lifting while focusing my energy on UX design and presentation made the entire build process lightning-fast.

What's next for SideLens

Next, I plan to add URL scraping so users can just paste a link to a news article instead of manually copying and pasting text, along with history tracking to save past analyses.
