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?
