All of the coolest Jev projects I could find on X today 🧵

1) Keystroke oracle
nader dabit@dabit3
Also have been playing with @typesafeai Jev, insane!
So many immediate use cases and new apps are possible. What a time to be a builder!
Sharing some experiments here starting with:
Keystroke oracle / predictive launcher:
Your launcher ranks by aliases, fuzzy match, and habit.
Jev reads intent: type "the pdf I just downloaded" and the newest PDF is already the top hit with a full confidence on every keystroke, in ~100 ms

2) Instant compaction
tamara@tamarajtran
found the perfect use case for @typesafeai Jev:
instant compaction
in 2026, why is compaction still a summarization prompt?
Jev can make it instant by scoring every tool call and dropping what’s irrelevant

P.S. I'll be testing Jev extensively this week and figuring out how exactly this new technology can be used in my business

4) Natural language DB search
Zachi@iam_zachi
I think I just cooked something 🔥
jev(): a PostgreSQL extension that searches your whole database in natural language. No index, no embeddings, just one function.
WHERE jev(people, 'could work from home')
or
WHERE jev(people, 'name sounds european')
129 rows judged in ~1s for $0.0009. Second run: 6ms from cache.

5) Browser controlled with voice
Moritz Kremb@moritzkremb
whoa this actually worked! Jev lets me control my browser in real time with my voice now
> i talk
> transcript sent to Jev
> jev returns probabilities in ~300ms
> browser clicks
costs: $0.0002 per decision
i'm stunned how fast this is. when i asked it to "go back", it even finished the request before i finished my sentence 😂

6) Email classifier
Riley Brown@rileybrown
Yeah Jev by @typesafeai is very cool. It classified 500 emails in seconds. And it costed 3.5 cents.

7) Browser use
Gregor Zunic@gregpr07
Breaking: Browser Use + Jev = Ultrafast ⚡
Findings flights took 7s and cost only $0.0039 🤯
> new action space every step
> DOM state space
> small LLM fallback to type
(this video is at 1x speed btw)
Built a tiny open source browser agent. try it below ↓

8) Trading bot
Jarrod Watts@jarrodwatts
I built a trading bot with Jev!
Jev decides if it should "buy" or "sell", given the price feed of an asset pair, and executes real trades.
It uses Monad to place the orders on Kuru's on-chain order book in every 300ms block.
Demo link → jev-trader.vercel.app

9) Tesla self driving
Justin Schroeder@jpschroeder
I rebuilt Tesla Full Self Driving with Jev in less than an hour.
This model is a total unlock.
