LennyGrowth
The AI writing tool Threads Creators actually use.
Most AI writing tools treat Threads as an afterthought. LennyGrowth is built only for Threads - your Brand DNA powers every post so it sounds like you, not ChatGPT. 18 modules (Hook Generator, Viral Vault, Smart Scheduler, and more) vs. the 3–5 features most competitors ship. Free to start, no card required.
Hey Product Hunt! 👋
I'm Lenny, building LennyGrowth solo, bootstrapped, no funding.
Backstory: 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 wrote them. Every "AI writing tool" I tried treated Threads as an afterthought, bolted onto a LinkedIn/Twitter product.
So I built the tool I actually needed.
LennyGrowth is Threads-only. Your Brand DNA (voice, tone, keywords) powers every output, so posts sound like you, not generic AI. Right now you get 6 core features on day one - ContentForge AI, Hook Generator, Idea Generator, Brand DNA, Viral Vault, Smart Scheduler - with 12 more advanced modules unlocked once you're comfortable. I didn't want to dump 18 features on someone in their first 5 minutes.
Honest bit: publishing is still copy-paste for now. Threads API access is in final testing with Meta and should land this week - one-click publish is coming, not a hypothetical.
Free to start, no card required: lennygrowth.com
Would genuinely love to know - is the copy-paste step a dealbreaker for you, or is the writing problem the bigger pain? And what would make you switch from whatever you use now?
