SplitPost: content repurposing that actually enforces your voice rules

I've used SocialBee, Buffer, Jasper, Copy.ai, and Castmagic. They all promise "your tone of voice". Most are just a ChatGPT wrapper bolted on to create quick captions, but none of them let you define specific rules and enforce them on every output. I'd spend 15-20 minutes per piece correcting the same mistakes the tool kept making.

SplitPost (splitpost.io) takes one piece of your content and generates platform-native posts for LinkedIn, Twitter/X, Instagram, Threads, Reddit, TikTok and Facebook, each in the relevant voice and formatting for that platform. You set voice rules (banned phrases, sentence pattern constraints, register checks) and every output gets validated against them before you see it.

Free tier, no card required. This is app three in 18 months as a non-technical solo founder in the UK. I'd genuinely like to know if the voice enforcement angle lands for anyone else or if I've built for a problem only I had.
