hi X

i'm pragun, 13, from india. i build AI that calls businesses' leads (leadflow) and an AI system that edits my instagram reels

gonna post what i build, what breaks, and the tech news i actually care about

[Pragun Gaur @pragunai]

experiment idea: same reel, edited by my instagram OS twice, once with opus 5.5 and once with sonnet 5.5

same prompt, same footage. i post both edits side by side and show the real time each one took

which one do you think wins?

question for people building with AI agents

what's the one thing you would never let an agent touch without a sandbox?

mine is api keys. curious what yours is

[Pragun Gaur @pragunai]

what are you building this week?

drop it in one line below. i'll reply to as many as i can with the first thing i'd fix or try

13yo, one macbook, 350+ cold calls deep. i've seen a lot of ideas get ignored

anthropic had claude prove 239 entry points across 123 open source libraries can't crash, for any input up to 64 MB

180 million lines of rocq proofs. it found hundreds of bugs fuzzers would almost never hit

writing code is easy now. proving it works is the new flex

350+ cold calls

most common reply: "baad me call karna"

nobody ever called back. not them, and honestly not most businesses with their own leads either

so i built an AI that calls every lead in minutes. it's called leadflow

duckdb 2.0 is out and the cli now has an "agent mode"

compact tables for input, errors as json. in their tpc-h test it cut the output the model has to read by 59%

dev tools are starting to be built for AI agents first, humans second. weird but i like it
