Introducing PostQuake: Posts That Shake the Feed

By Joseph Sebastian Ruiz••7 min read
PostQuake: Posts that shake the feed. Three phone-sized slideshow slides fanned out, the front one reading “everyone in my group chat thinks they're psychic.”

PostQuake is my new tool for anyone with something online to promote. Paste a link to your app, website, online shop or newsletter and get back a week of TikTok-style slideshows and videos, ready for TikTok, Instagram Reels, YouTube Shorts and Facebook. Early access is open now at postquake.app.

Six days ago I shipped Psychic Tournament to Google Play and the App Store. Then I ran into the part nobody warns you about: launching happens once, and the marketing never stops.

The problem

Short-form video is the cheapest way for a small app, site or shop to get discovered, and the feed rewards people who post often, for weeks, without running out of ideas.

Every one of those posts is six jobs: an angle, the copy, the images, the video, a caption and a schedule. Then you do it again for each platform. Most makers, me included, post for a few days, get pulled back into the product, and lose all their momentum by week two.

I didn't want to hire an agency, and I didn't want to become a full-time content creator. So I built the tool I wanted.

What PostQuake does

One link in, a week of posts out:

  1. Import your product. Paste an App Store or Google Play link, or any website. PostQuake pulls in the name, pitch, icon and brand colours, and takes screenshots from the store listing or from your site itself.
  2. Learn who it's for. A one-time, ten-question interview about what you've made, then research into real reviews and forum threads. The result is a customer profile written in your customers' own words, with every quote sourced. Nothing is made up.
  3. Write, check, render. Pick your formats and how many posts you want. Every hook, slide and caption is written for that customer, checked against the format's rules and the rest of the batch, then rendered as 1080×1920 slides and an MP4 with licensed music.
  4. Ship it. Export a ready-to-post bundle with a posting plan, or schedule directly to TikTok, Reels, Shorts and Facebook Pages. Direct scheduling is rolling out now.

Not just apps

I built PostQuake for an app, but nothing about the problem is specific to apps. If it lives at a link, PostQuake can market it:

  • Mobile apps and games, from an App Store or Google Play listing
  • Web apps and SaaS, landing pages and portfolios
  • Online shops, like Shopify and Etsy storefronts
  • Newsletters, blogs, podcasts and channels
  • Courses, communities, events and local businesses with a website

Give it a website with no store listing and PostQuake screenshots the site on a phone for the slides that show your product, then ends each set on a card with your domain. I tried it on this site. PostQuake imported overninethousand.com as itself, captured it on a phone, and rendered these closing slides:

Two PostQuake slides for overninethousand.com: the site's real homepage in a phone frame under the caption “overninethousand.com”, and a closing card reading “OverNineThousand, Link in bio, overninethousand.com”

Its first customer is my own game

I tested PostQuake on the app I'd just launched. Here's one Psychic Tournament set, exactly as PostQuake rendered it:

A five-slide PostQuake set for Psychic Tournament: “everyone in my group chat thinks they're psychic,” a two-slide story about 25 hidden cards and beating chance, a real screenshot of the Zener game, and a store card

It opens with a hook, tells a two-slide story, shows a real screenshot of the game and ends on a store card. The story stays inside the real maths: pure chance gets you about 5 out of 25, which is the same honest baseline the game itself draws on every result.

The first batch was seven sets across three formats, each with its own angle and all written from the customer profile. The image cost for the whole batch was about $2.73.

Slides from a listicle set (“3 intuition tests you can try tonight, no account needed”) and a before/after set (“i practise blindfolded but never know how i actually did”)

The people in these photos are AI-generated. PostQuake knows that, and it marks those sets so they carry an AI label when they're published. Swap in your own photos and the label goes away.

That batch is scheduled to start going out on September 30, one set a day. I'll be tracking views, saves and installs, and I'll share what worked and what flopped here.

Honest marketing, on purpose

Psychic Tournament's design brief was honest odds. PostQuake's is honest marketing. Churning out slideshows is easy. The hard part is doing it every week without repeating yourself, getting your account flagged, or making claims you can't back up. So PostQuake has rules it won't break:

  • It never posts the same thing twice. Every set is checked against its format and the rest of the batch before anything renders. Duplicate hooks and captions are rejected, and near-duplicates are flagged.
  • It won't write fake reviews. Customer quotes have to be real and sourced. Mocked chats and notifications are labelled on the slide as dramatizations and never passed off as real users.
  • AI labels are handled for you. Sets with AI imagery are labelled wherever the platform asks. Sets built from your own photos or licensed stock don't need one. Provenance is never stripped.
  • It uses licensed music only. Videos use tracks with a recorded licence, and anything else is refused before it can get you muted.
  • It costs pennies per post. AI images run about 10 cents each, and cached images cost nothing to re-render. Slides, videos, mock phone screens and store cards all render for free.

What's coming

Here's where each piece stands:

  • Rolling out now: direct scheduling across TikTok, Reels, Shorts and Facebook.
  • Next: a web app, so you don't need a terminal. Also hook A/B variants, per-post attribution (installs, sign-ups or sales), and your own brand kit.
  • The Seismograph: every post gets a Magnitude score, with views, saves, shares and installs or sales rolled into one number. Posts that land spawn Aftershocks: fresh posts that reuse the winning format with new angles. The idea is that the posts that work produce more posts like them.
  • Later: a trend finder for formats that are working right now, a format cloner for slideshows you like, screen-recorded demos of your real app or site, dedicated importers for shops and channels (Shopify, Etsy, YouTube, newsletters), voiceover formats, and more platforms (Pinterest, LinkedIn, X and Threads).

Get early access

I'm letting makers in a few at a time while I dogfood PostQuake on Psychic Tournament. Today it runs alongside an AI coding assistant: you tell it what you want in plain English and it drives PostQuake for you, so you'll need to be comfortable opening one. The web app, which anyone can use, comes next.

Early-access members get new builds as they land, a direct line to me, and a say in which formats come next. If you've shipped an app, a site or a shop and marketing is the part you keep putting off, I'd love to hear what you're building. My inbox is at overninethousanddevelopment@gmail.com.

And no, PostQuake isn't the new app I mentioned last week. That one's still coming.

Stop making posts. Start making waves.
