LennyGrowth — The Threads AI Writing Tool Built for Creators Who Actually Ship

I post on Threads daily and average 500k+ monthly views. The thing that ate most of my time wasn't posting - it was writing hooks that didn't sound like ChatGPT or generic Claude wrote them. So I built the tool I actually needed.

LennyGrowth is a Threads-only AI writing platform. Not a LinkedIn/Twitter tool with a Threads tab bolted on - built around one problem: helping solo creators ship content that sounds like them, every day, without burning out.

What's live right now (6 core features):

ContentForge AI - turns a rough idea into a full post or thread, matched to your tone
Brand DNA - store your voice, keywords, and mission once; every output stays on-brand
Idea Generator - 10 tailored post ideas when you're stuck
Hook Generator - 10 scroll-stopping hooks in proven formats (curiosity gap, bold claim, story arc)
Viral Vault - save and tag your best posts, recraft them for new angles
Smart Scheduler - best-time-to-post engine with calendar view and draft queue

There are 12 more modules under an "Advanced" menu (Viral Score Checker, Post Autopsy, Caption Rewriter, Analytics, Repurpose Engine, and more) - but new users only see the 6 core ones first. I'd rather have people actually use 6 features well than get lost in 18 on day one.

The honest part: publishing is still copy-paste. Threads API access is in final testing with Meta and should land this week. I chose to build the writing engine first, because that's the part people actually struggle with daily - publishing is just one click once the API is live. If copy-paste is a dealbreaker for you right now, I get it - but I'd rather ship a strong core than wait months for API access to start building anything.

Traction (3 weeks in beta): 50+ creators, 2.2k posts generated, daily active usage holding steady. No paid revenue push yet - focused on free-tier traction first.

Pricing:
Free - 15 AI posts/month, unlimited scheduling
Starter - €9/mo
Pro - €19/mo, unlimited posts, all 18 modules
Team - €49/mo, 3 seats

I'm bootstrapping this solo, no funding. Built it because every existing tool treated Threads as an afterthought.

Genuinely curious: would a copy-paste publish step be a dealbreaker for you, or is the writing problem the bigger pain point? Roast it, break it, tell me what's missing.
