Found something good?

I've been mass-producing TikTok slideshows with AI and scheduling them weeks in advance. Zero filming. Zero editing. Zero daily posting grind.

This article breaks down the exact system, step-by-step, and the slideshow generator is open source and FREE - you just bring your own API keys.

1. Why slideshows?

TikTok is pushing slideshows HARD right now. They routinely outperform videos on fresh accounts, and the algorithm seems to give them an extra distribution boost.

They're practically free to make. No filming, no UGC creators, no editing. Just images + text. Which means it's a distribution channel you can completely automate.

With paid ads I'm spending hundreds to find a winner. With slideshows, my cost per post is effectively $0.00 in API credits. Even if 95% of them flop, the 5% that hit are pure profit - and they drive installs on autopilot while I sleep.

The strategy is volume. You're not trying to craft one perfect post. You're flooding the algorithm with variants and letting it find the winners for you.

2. How it works

Scrape Reddit → Generate text with AI → Render slides with ffmpeg → Schedule everything to Post-bridge

Here's what each step does:

1. Scrape Pinterest - Apify pulls images from Pinterest. These are your slide backgrounds. Pinterest is an endless free goldmine of aesthetic, native-feeling images - and far, far cheaper than generating them with AI.

2. Generate text - an LLM (via OpenRouter) writes the hooks and slide text. Prompted to match the viral slideshow formats already working on TikTok.

3. Schedule with Post-bridge - each slideshow gets pushed to Postbridge's queue via their API, spread across however many accounts and days you want.

The whole thing is open source: https://github.com/athcagithub/SlideSmith

3. Setup (5 minutes)

You need zero technical ability for this. If you can copy-paste, you can run it.

How to setup:

1. Clone the repo: git clone https://github.com/athcagithub/SlideSmith

2. Run "npm install" then "npm run dev"

3. Visit https://localhost:5173/

4. Add your post-bridge key in the settings panel:

That's it. No database setup, no deployment, runs locally. You can push it to vercel too if don't want to "npm run dev" every time.

4. Generating & scheduling

Click "Generate" and it'll spit out slideshows in bulk. Each one gets a hook, slide text, and rendered images - all unique variants.

Curate them, filter out the shit ones, schedule the good ones. This takes me maybe 10 minutes.

My exact routine: 20 posts a day, scheduled 30 days out. That's 600 posts a month. Batched in one sitting, then I forget about it. Postbridge drips them out across my accounts on schedule, and I check the analytics once a week to see which formats are hitting.
