OncePost

OncePost is an AI-powered content repurposing tool built for solo creators and solopreneurs who publish across multiple platforms. Paste any long-form content - a blog post, video transcript, newsletter, or rough idea - and get platform-native posts for 9 channels in under 60 seconds. What makes it different: voice training Most repurposing tools just reword your content. OncePost matches your tone. Paste 3-5 samples of your own writing during setup, and the AI learns how you actually write - your sentence length, your rhythm, your word choices. Every output sounds like you, not like a robot trying to sound like you. 9 platforms, each formatted the way that platform expects Twitter/X threads are punchy and numbered. LinkedIn posts have a narrative arc and breathing room. Instagram captions are conversational with a clear call to action. Reddit posts match the community's no-BS tone. OncePost doesn't just copy and paste your content into a shorter box - it restructures it for how each platform reads. Supported outputs: Twitter/X, LinkedIn, Instagram, Facebook, Bluesky, Reddit, Email newsletter, Thread, and Blog Summary. Key features - Voice training: paste your own writing samples to match your tone - 9 platform outputs generated in a single run - Full repurpose history on your dashboard - click any past run to reload all outputs without spending credits - 5,000 character input limit with a live warning before you hit it - Free tier available - no credit card required to try it - Upgrade prompts are friendly, not punishing - free users see a clear path forward, not a raw error Who it's built for OncePost is for the person doing everything themselves. The solopreneur who writes one good piece of content and needs it to show up on LinkedIn, in their newsletter, and on Twitter without spending another hour reformatting. The creator who wants to stay consistent across platforms without hiring a social media manager. The builder who wants to stay focused on their product, not on content logistics. Pricing - Free: limited repurposes per month, full access to all 9 platforms - Creator ($19/mo): expanded credits, full history, voice training - Pro ($49/mo): highest credit limit, priority generation, ideal for high-volume publishers Built by a solo founder OncePost is an indie SaaS built and run by a solo founder. It's not backed by a team of 20 or a $5M seed round - it's a focused tool built to solve a real problem that kept coming up: great content sitting on one platform while every other channel stayed quiet.
