Factly — Project Story

I built Factly because the internet’s pace has outgrown our ability to think critically in real time. One night scrolling on X (Twitter), I saw a headline that felt too good to be true. It was.

A quick check against reputable outlets showed it was false, yet the replies were full of people saying things like “wow, hadn’t heard this before.” It hit me: most of us read between bus stops and lunch breaks. We rarely have the time nor the energy to manually verify every claim we see scrolling online. The speed of information has outpaced the speed of critical thinking.

Factly is my attempt to slow the spread of misinformation without slowing people down.

What I built

• A browser extension that highlights claims on any page and shows a compact, in‑context fact check: verdict, confidence, a short explanation, and cited sources—right where you’re reading.
• Verdict tiers: Supported, Misleading, Refuted, Unclear, and Insufficient Evidence.
• Non‑destructive, color‑coded highlights so users can skim and keep scrolling.

What inspired me

• Watching misinformation gain traction because it’s fast and easy, while fact checking is slow and hard.
• Realizing that “do your own research” is reasonable advice but unrealistic instruction considering the speed of modern feeds.

Why it matters (social/public impact)

Factly meets people where they are—inside their browser. It elevates credible context at the moment of impression, not after a tab ridden rabbit hole. That’s a small but meaningful push toward healthier information consumption.

Sponsor tracks (how Factly fits)

• Social/Public Impact: a practical way to slow misinformation without slowing readers.
• Best Use of Claude: structured reasoning with strict JSON output; Claude excels at concise, grounded explanations.

What’s next

• An auto-check feature that automatically starts fact checking the moment a page is loaded.
• Per‑domain trust lists and on‑device caching for even faster results.
• Further pipeline optimizations for increased speed and efficiency

Thanks for reading, and thanks for caring about the quality of what we read. The goal isn’t to replace judgment, rather to give it a fighting chance at feed-speed.
