Your AI motion designer,
inside After Effects.
Describe a shot or paste a reference. Opac X builds it in your open comp as real layers, effects and keyframes, checks its own frames, and hands you something you can still edit.
Full access for 3 days · no card required · then $79 once
Works with what you already have
Three prompts, three finished comps.
Nothing on this page was mocked up for the website. These are the comps Opac X wrote in After Effects, playing exactly as they were rendered — every layer still open and editable in the project file.
›Streaming-app hero page for a horror film: dark UI, big title, watch button, poster row. Use Pexels for the stills.
8 stills fetched and placed · nav, title, synopsis, buttons and poster row as live layers
›Music-player carousel: five cards fanned out, centre card in focus, player bar below. Animate the swipe.
Five cards on one slider control · scrub it to change the focused card
›Glass card on black. Big headline, an ember glow rising from the bottom, subtle top highlight.
Card is a shape layer, glow is a gradient ramp · nothing pre-rendered
It runs on your machine, under your own account.
Opac X is a panel, not a service. There is no account to create here, and nothing of yours sits on our servers.
No API key, no middleman
Opac X drives the Claude Code CLI already signed in on your computer. Your prompts travel from your machine straight to Anthropic — we are not in that path and we never see them.
No analytics, no telemetry
The panel does not phone home. The only thing it ever sends us is a licence check: your key and a hashed machine id. Never your project, never your prompts.
A bad step is always recoverable
Every write is wrapped in one undo group, and checkpoints snapshot the project as it works. When a build goes wrong you step back — you don't start over.
Four things it does that a preset pack can't.
Every result is native After Effects: layers, effects and keyframes you open and change. Nothing is pre-rendered, nothing is grouped away.
Build a comp from one sentence.
Describe the shot. Opac X reads your project first, then writes real After Effects layers — shapes, text, solids, effects and keyframes — laid out on an 8-point grid with a proper type scale and safe margins, not eyeballed coordinates.
- Reads the open comp before it touches it: layers, fonts, your installed scripts
- Every layer is native and editable. Nothing is rendered flat or locked
- Each step is one undo group, so Ctrl+Z is always exactly one step back
Rebuild a reference — image or video.
Paste a screenshot and it counts the elements, reads the palette and type, and keeps the asymmetry instead of averaging it out. Drop in a video and Opac X analyses it on your machine first: frame differencing finds every cut, every transition and how long it takes, and the shape of the easing — then sends a labelled storyboard, not a slideshow.
- Cut times, transition durations and easing shape — measured, not guessed
- Standard (26 frames) or Detailed (48 frames) per clip. You choose
- The video analysis runs locally and spends none of your AI plan
It looks at the frame before you do.
After each step Opac X renders real frames of your comp through a throwaway proxy — your layers are never touched — and inspects them as a contact sheet for overlap, misalignment, contrast and scale. When something can't be done it says exactly what: a property that wouldn't set, an expression that broke, a layer that never appeared.
- 6 to 10 frames sampled per pass, plus a pixel diff between first and last
- Failed property sets and broken expressions reported by name
- You are never told a build worked when it quietly didn't
Real 3D through Blender, two ways.
When a shot needs 3D, Opac X drives Blender in the background. Rendered: the full Blender look — fur, materials, global illumination — delivered as a PNG sequence with alpha and imported as one footage item. Live: the model comes in as an editable 3D model layer, so you animate it and move an AE camera through it with ordinary keyframes.
- A cheap preview still first, then the sequence. Up to 600 frames per call
- Live model layers need After Effects 24.4+ with the Advanced 3D renderer
- Optional. Without Blender it builds the shot in 2D and tells you once
The rest of what's in the box.
The full list, so you know exactly what you're paying for.
Brand logos fetched by company domain and imported as layers. 150,000+ vector icons from Material, Lucide, Phosphor, Tabler, Heroicons and Carbon. It never hand-draws a logo from shapes.
Pexels, Pixabay, Unsplash and Freepik with your own free keys. Results come back as a numbered contact sheet so it picks by looking, then imports the file next to your project. Optional, off by default.
Textures, backgrounds and mood frames from OpenAI, Ideogram, Stability or Pollinations, with your key, auto-imported into the project. Optional, off by default.
Crash-safe snapshots of the .aep before risky work. Reverting branches the current state first, so a rollback is itself undoable. Listed in the History tab and kept after you close the project.
Reads your comps, the full layer list, installed fonts and your own .jsx scripts — and can run those scripts. Dumps a layer's real property tree instead of guessing an effect's indices.
Reads existing keyframes on any property, transform or nested effect, so it can extend or match animation already in your comp rather than build over it.
Ask for a dashboard and it builds a persistent, dockable panel from HTML — sandboxed, no network, no re-signing. Up to four at once.
A 43 KB bundled motion-graphics reference: layout hierarchy, timing and easing, ExtendScript safety, expressions, product-UI motion, Blender. Ask it to remember a client's title style and it saves that as a skill for future sessions.
Claude Code by default, and the tested path. Codex and OpenCode adapters are included for people already on those plans.
One agent run per message, no background polling. Reference detail is a setting — Standard or Detailed — so you decide how much of your plan a rebuild spends.
Three steps, once it's installed.
Open the panel
Window → Extensions → Opac X, docked wherever you like alongside your existing panels.
Describe it, or paste a reference
Type what you want, or drop in an image. Opac X works in your open composition.
Take over
You get real layers and keyframes. Adjust anything, or ask for a change in the same conversation.

| After Effects | 2022 or newer (version 22 and up) |
| Operating system | Windows 10 or 11 today. A macOS build is in development, with no date yet. |
| Internet | Required. Opac X checks your licence and fetches assets online. |
| AI agent | Claude Code by default; Codex or OpenCode if you prefer. One command to install the CLI, then sign in from inside the panel with that account. Two minutes, once. |
| Blender | Optional, free, and only needed for the 3D features. |
Setting up Claude takes about two minutes, once. Opac X has no AI subscription built into the price — it runs Claude on your own machine under your own account. That is why it costs $79 once instead of every month.
- Install Claude Code. One line in PowerShell: irm https://claude.ai/install.ps1 | iex
- Open the Opac X panel and sign in. It shows a Sign in to Claude button, opens a terminal for you and signs you in through your browser. You never touch an API key.
- That's it. Start describing shots — you won't be asked again.
You don't need the Claude desktop app or an editor plugin — just the command-line tool from step one. Prefer Codex or OpenCode? Install that CLI instead and sign in the same way from the panel.
One payment. It stays yours.
Start with 3 days free — the full thing, no card needed.

What it actually costs
Opac X runs Claude Code under your login, so AI usage sits on your plan instead of being bundled into the price. Trying it out is cheap; rebuilding a detailed reference is real work and uses real quota. We would rather you knew that before buying than after.
Common questions.
Do I need to pay for anything else?
You need a Claude account, because Opac X runs Claude Code on your machine under your own login. That is separate from this purchase and is not included in the $79. Nothing else is required — Blender is free and optional.
What do I get in the free trial?
Everything. The trial is the full product for 3 days — not a limited version, not a watermark. You get a licence key that stops working after 3 days, and buying swaps it for one that doesn't. You still need Claude Code set up first, same as the paid version.
Can I use it on my laptop and my desktop?
A licence covers one machine at a time. To move it, open Settings › License in the panel on the old machine and press Remove — that frees the seat — then activate on the new one. Do it before you wipe or sell the old machine.
Does it need internet all the time?
It checks your licence periodically rather than on every build, so short offline stretches are fine. It cannot run permanently offline.
Who owns what it makes?
You do, completely. Everything Opac X builds in your project is yours to use commercially, with no attribution and no restrictions from us.
Is it a plugin or a script?
An extension panel that docks in After Effects like any other. It builds with normal After Effects features, so your project opens fine on a machine that has never had Opac X installed.
What if it makes a mistake in my project?
You step back, you don't start over. Every change Opac X makes is wrapped in a single undo group, so one Ctrl+Z reverses a whole step rather than fifty. It also takes checkpoints of the project as it works, and you can roll back to any of them — reverting branches your current state first, so a rollback can itself be undone.
Does my project leave my computer?
Your files never do. What goes to Anthropic is what you'd send by using Claude Code yourself: your prompt, any reference image you attach, and a text summary of the composition — layer names, sizes, colours, timings. Not the project file, not your footage, not your media. That traffic goes from your machine to Anthropic under your own login; it doesn't pass through us. The only thing Opac X sends us is a licence check containing your key and a hashed machine id.
Will using it put my Claude account at risk?
No. Opac X uses the Claude Code CLI the ordinary way, under your own signed-in session — there's no automation of the web app, no shared key, and no second account. It is the same usage Anthropic expects from anyone running Claude Code. Note that builds do consume your plan's usage, which is why the cost is spelled out above rather than hidden in the small print.
How do I get updates?
Updates are free for life — every future version is included in the one payment, and your existing licence key keeps working with all of them. They ship as a new download of the same package. Sign in at app.lemonsqueezy.com/my-orders with the e-mail you bought with (or use the link in your order e-mail), download the current file, install it over the old one and restart After Effects. The panel checks once a day and shows a notice at the top when a newer version exists.
Does it work on Mac?
Not yet. Opac X is Windows-only today. A macOS build is in development, but there is no release date, so don't buy it for a Mac yet. When it ships it will be announced here and on Instagram.
Stop building motion graphics manually from scratch.
One payment, one machine, and it works in the composition you already have open.
