After Effects
mirAI
mirAI operates After Effects for you — describe what you want in plain language and it builds it, then checks its own work.
Bring your own AI assistant — Claude Desktop, Claude Code, Cursor and other agent tools drive After Effects through mirAI (MCP). Everything runs on your own machine.
Google Gemini, OpenRouter's 300+ models with a single key, or your own endpoint.
One plugin. Your AI, inside After Effects.
mirAI — The Next-Generation AI Agent for After Effects
No more searching through menus or clicking repeatedly. Just describe your task in simple terms, and let mirAI handle the tedious work. You can focus on your creativity.
mirAI now supports OpenRouter + Gemini.
Access 300+ AI models (GPT, Claude, Grok, DeepSeek, Llama, Mistral, etc.) with one API key and switch instantly. One plugin. Every top AI model.
And now your AI assistant can drive After Effects itself: connect Claude or any MCP client and it works through mirAI. Optimized by mirAI end to end — your assistant asks for the result, mirAI handles the After Effects side, and every step is checked on a real rendered frame instead of guessed at. Windows and macOS.

Streamline Your Workflow: From Natural Language to Action
- Consultation Mode: A creative partner available 24/7, 365 days a year. From keyboard shortcuts to complex workflow ideas, ask any question about After Effects and receive expert advice instantly. 🤖
- Precise Alignment: Align text in-points to layer markers or position layers with mathematical precision—all with simple text commands.
- Instant Actions: No more guessing what your footage means or searching for detailed compositing settings. Just enter your intent (e.g., “Set all footage to 8 fps”), and mirAI will complete the batch processing in seconds.
From natural language to action: Instantly convert your thoughts into scripts or expressions while you chat.
Batch Processing: Batch duplicate and modify multiple layers simultaneously.
Deep Copy [NEW]: Recursively duplicate compositions including all nested sub-compositions, saving them as independent copies.
AI-Powered Renaming: Intelligent layer naming based on content analysis.
Collision Avoidance Rig [NEW]: Set up collision avoidance expressions for selected layers with a single click. No more overlapping layers!
World Link (Up/Down): Easily synchronize coordinates between nested components.
AI Music [NEW]: Instantly generate original background music that matches your composition's mood. mirAI analyzes your visuals and creates perfectly fitting BGM — instrumental or with vocals, from 30-second clips to 3-minute full tracks. One click to generate and place on your timeline.
mirParticle [NEW] — a real-time 3D particle designer inside After Effects:
Design with a live WebGL preview, then bake straight into AE — as an editable null chain, or an image sequence (alpha PNG / 32-bit EXR with Z-depth). Driven by natural language plus tags, no keyframing to start.
- AI-first — type "butterfly" for an original point cloud, or hit AI AUTO for a full auto scene (shape, motion, color).
- Stackable motion tags — turbulence, swirl, explosion, assemble, connect-lines, trails (lines / dots / images / text), gravity-sphere attractor, and more.
- AE-aware — send particles along your camera or a layer's path; reads Position keyframes and mask/shape Bézier curves.
- Storyboard — morph multiple cuts in order, matched to the active comp camera.
Smart Auto-Fix: Input your intent in plain language (e.g., "Soft Bounce" or "Slow Rotation") directly into any AE expression field. mirAI detects it and converts it into functional code instantly.
moCC (Motion Copy Control) [NEW]: Clone animation across multiple layers without changing their positions, then fine-tune with AI instructions.
AI Chat (Multilingual Support): Chat in your native language, including English, Japanese, Korean, Chinese, Spanish, French, German, Thai, and more.
Voice Input: Supports 30+ languages via cloud STT. (Note: AI input supports 30+ languages. The UI is fully localized in English and Japanese, with additional language options for Korean, Chinese, Spanish, French, and German.)
AI Narration [NEW]: Automatically generate perfectly timed voice-overs for your video. mirAI analyzes your composition to suggest narration markers, creates the script, and smartly trims the text based on language character limits to guarantee audio never overlaps. One click to generate high-quality TTS audio and place it directly on your timeline.
Performance, Reliability & Cost Efficiency
- Transparent, Flexible & In Your Control: mirAI runs on your own API key — no hidden fees, no subscription lock-in. You choose the provider and the model, from budget to top-tier, and switch anytime. With OpenRouter and custom connections, you're never tied to a single vendor's pricing.
- Custom Connection [NEW]: Beyond Gemini and OpenRouter, connect any OpenAI-compatible endpoint or your own local server — run models locally to keep costs and data fully in your hands. Your setup, your rules.
- Continuous Optimization: Our core logic has been repeatedly refined to reduce redundant data processing and keep token usage as efficient as possible.
- Manageable Creative Power: The latest version is optimized to keep daily expenses sustainable. We recognize that rich features like image generation, AI music, or narration vary in token usage, so our smart routing works to keep your usage efficient.
- Rock-Solid Reliability: mirAI's proprietary protection system significantly reduces script errors, delivering more stable results in After Effects—even with cost-effective models.
Requirements & Safety
- Requirements: Adobe After Effects 2024 or later (Windows and macOS), an internet connection (for cloud providers), and an API key — Google Gemini, OpenRouter, or any OpenAI-compatible endpoint (local servers also supported). (Note: The Google Gemini API free tier is a great way to get started and try mirAI.) Fully localized in English and Japanese, with additional UI language options for Korean, Chinese, Spanish, French, and German.
- Safety Note: Always save your project before executing scripts generated by AI.
- Privacy: Visual data (screen analysis) is sent to your selected API provider (Google, OpenRouter, or your configured endpoint) for processing. Please disable this feature for sensitive or confidential projects.

・Unflatten — the opposite of Flatten Image. One layer holding several separate drawings is split into a layer per piece, read from the alpha channel, each with its anchor at its own centre so it is ready to animate.
