Your feed is.

collapse in screen attention span since 2004. The feed trained that.

edgi wraps every idea in a 60-second loop.
Short enough to finish. Dense enough to stick.

01 — The spark

A lesson the length of a TikTok.

Every spark is a tight 60 seconds of narrative that leaves you with something real — an analogy, a number, a story you'll retell at dinner.

  • ✦ Entertaining substance, not textbook definitions
  • ✦ Instant recall checks, spaced repetition baked in
  • ✦ Eight levels of depth, for the days you want more

02 — The chain

Pull one thread.
Six more light up.

Finish a spark, pick what you're curious about next. Keep going.

03 — The map

Everything you learn
stitches into one picture.

Every concept you touch becomes a node. Every connection you make becomes an edge. After a week, you start noticing patterns that feel suspiciously obvious in hindsight.

04 — On demand

A podcast on whatever
you wondered about
this morning.

Type a topic. Get a full visual podcast — narrated, scored, paced — in three minutes. Hands-free for the walk, the commute, the dog park.

  • ✦ Real voices. Real sources. No hallucinated nonsense.
  • ✦ Visuals that pace with the audio
  • ✦ Yours forever — save, share, send to a friend

05 — The twist

First you learn it.
Then you teach it.
That's when it sticks.

Most apps stop at consumption. edgi keeps going. As you learn, the app quietly walks you up a ladder — until one day you're the one people are listening to.

The proof

You don't really know it
until you can explain it.

edgi is the only feed that asks you to teach back. Tap the mic, take 30 seconds, and explain a concept like you're talking to a friend. The AI scores it sentence-by-sentence, calls out what you nailed, and flags what you fudged.

  • ✦ Per-concept stars — granular feedback, not a vibe check
  • ✦ Bronze · Silver · Gold tiers — the Gold ones go live
  • ✦ Your best proofs become the lesson the next person sees

Most apps stop at consumption. edgi makes you the one people are listening to.

In their own words.

"I opened it to look up what a mitochondrion actually does and forty minutes later I was reading about the Cambrian explosion. I didn't even notice the time."

James Okafor Founder, Ledgerline · London
"I replaced my morning Instagram scroll with this. I'm not saying I'm smarter — but I'm not finishing breakfast angrier anymore."
Priya Sundaresan PhD candidate, Neuroscience · Boston
"I made a podcast about octopus cognition for my girlfriend. She made one back about the Medici. This app is going to ruin dinner parties — in a good way."
