Why We Built PostClaw
Updated October 2026: plans and AI models have changed since this was first published. Current details are on the pricing page and in how bring-your-own-key works.
Last year, I was running social media for a small brand. Nothing huge — just trying to keep Twitter, Instagram, LinkedIn, and TikTok alive. Every Monday morning looked the same: write a post, copy it, open Twitter, paste, tweak the hashtags, open Instagram, paste again, crop the image, open LinkedIn, rewrite it to sound more professional, open TikTok... you get the idea.
Four platforms. One piece of content. Somehow an hour gone.
I tried the usual tools. Buffer, Hootsuite, Later. They're fine for scheduling, but they don't help you create. And in 2026, when AI can write a decent first draft in seconds, why am I still doing everything by hand?
That's how PostClaw started.
The idea is simple
You tell PostClaw what you want to say. It writes it, adapts the format for each platform, and schedules it everywhere. We launched with eight platforms; today it publishes to 18, from Instagram, TikTok and YouTube to WordPress and Medium — one dashboard.
But here's what makes it different from the "AI-powered" label that every SaaS tool slaps on these days: PostClaw actually understands that a LinkedIn post and a tweet are fundamentally different things. It doesn't just copy-paste with different character limits. It rewrites. A thread for Twitter. A more polished piece for LinkedIn. A visual-first caption for Instagram.
We went a bit further than we planned
Honestly, the project grew beyond what we initially scoped. We started with text, but then we thought — what about video? Creators need video content constantly, and making it is still painfully slow.
So we built a Video Studio. You can pick from 12 templates that auto-generate videos from your content, or go full creative mode with an 8-step pipeline where you control every detail. Need a voiceover? We integrated ElevenLabs with 15 voices that actually sound good. Need background music? Generate it with AI or browse stock tracks from Jamendo.
We also plugged in Pixabay, Pexels, Unsplash, and Freesound so you're never stuck searching for stock assets in a separate tab.
Your keys, your models
This one matters to us. A lot of tools lock you into their AI backend and charge you a premium for it. We didn't want to do that.
PostClaw supports BYOK — bring your own key. If you already have an OpenAI, Anthropic, or Google API key, just plug it in. You pay them directly, no markup from us. We support over 20 providers.
New accounts get a one-off trial of 20 AI calls to try it before adding a key. After that, writing and chat run on your own key on every plan, including Free. Image, video and voice generation are on paid plans, and run on your own key there too.
Workflows for the tinkerers
Some people just want to click "post" and move on. Others want to build intricate content pipelines. We built for both.
PostClaw has 14 built-in tools you can chain together into automated workflows: write content, generate images, create video, add music, add voiceover, schedule posts, track analytics — all connected. Think of it like Zapier, but specifically for content creation.
What it costs
The Free plan is actually free: connect 2 social accounts and use the AI on your own key, with no credit card. Paid plans add more accounts and AI media. The current plans are on the pricing page — we keep them there so this post does not go stale.
The nerdy details
For anyone curious: the backend is Go (fast, low memory), the frontend is React with SSR, data lives in PostgreSQL, and real-time updates come through Server-Sent Events. We run lean — one small server handles a lot.
Come say hi
We're building PostClaw in the open and shipping every week. You can see what we've been up to in the changelog, or just drop us a message — seriously, we read everything.
If any of this sounds useful, give it a try. Worst case, you spent five minutes and it wasn't for you. Best case, you just got your Monday mornings back.
