What it does

Synapt is a Chrome extension that helps creators spot viral posts early on X, LinkedIn & Product Hunt, then craft AI replies/posts that sound like you. Grow your audience faster while saving 70% of the time you’d normally spend scrolling and replying.

Chrome extension for X, LinkedIn, and Product Hunt. Spot heating posts by view velocity on X. Draft AI replies in your voice. Edit before you post.

Borrow distribution on X: spot posts still climbing by views per minute, draft a reply that sounds like you, and send it before the conversation cools off. You open X to engage. An hour later you've scrolled past the posts that still had oxygen. Most of what you see already peaked. Reply anyway and you're talking into an empty room. By the time you craft something worth posting, the thread has moved on without you. Generic assistants erase your voice. Editing them takes as long as writing from scratch. Minutes, not a migration. No content calendar to rebuild. Just the feed you already live in. Add Synapt from the Chrome Web Store. Sign in, paste your API key once. It lives under the posts…from synapt.app

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  • Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
