After Effects AI Agent

Your Agent Partner inside After Effects.

Tan reads your live AE project, writes expressions, runs production edits, and turns repeat work into reusable motion workflows.

Logo overshoot fix
Animate text A–J
Null parent setup
Client titles pass
The logo in "Title Reveal" bounces too hard. Tighten the overshoot on position Y.
Tan
get_layer_expression · "Logo" · Position Y
overshoot = 0.40 · freq = 2.8 · decay = 4.2
set_expression · overshoot → 0.18
Done. Position Y expression updated — overshoot reduced to 0.18. The bounce now settles in the same window.
Also add a wiggle on the X axis, subtle — same decay rate.
Tan
set_expression · Position X · wiggle amp 4px
Position X now has a 4px wiggle at decay 4.2 — matches the Y settle timing.

Your Comp Is the Brief
Tan reads your project, comps, layers, selections, and effects directly from After Effects. Ask for the result. Skip the background lecture.

Applied to "Logo" · Position Y · "Title Reveal" · line 3: 0.40 → 0.18

Expressions, Aimed Correctly
Reference the exact comp, layer, or property. Tan writes expressions for the real target, backed by maintained AE knowledge instead of generic examples.

The Boring Pass Belongs to Tan
Frame-by-frame text changes. Similar comp tweaks. Cleanup passes. Repeated layer work. Give Tan the mechanical work and keep your time for design.

From Habit to Script
Turn the operations you repeat every week into scripts Tan can help create, save, and run from the extension panel.

See. Make. Reuse.

See
Tan starts from the AE project in front of you. Active comps, selected layers, open effects, current properties — already in the conversation.
Make
It uses tools, Knowledge, and Skills to help create the edit. Not just suggestions — actual actions running inside After Effects.
Reuse
Good workflows become faster the next time. Package what works into Skills. Let production knowledge compound instead of getting forgotten.

GPT-5.4
Quick Tan

Built by someone tired of explaining After Effects to AI.

Four things that shaped every design decision in Tan.
01
AE context should not be typed by hand.
The active comp, selected layer, target property, effects, and project structure should already be part of the conversation. Typing it out every time is friction that has no business existing.
02
Expressions are not side quests.
They are how motion designers build flexible controls, client-editable systems, and effects that would be painful to keyframe manually. Tan treats them as first-class work — not afterthoughts to paste from Stack Overflow.
03
Knowledge is the product edge.
Tutorials, internal tricks, effect recipes, expression patterns, and studio conventions can become usable context for the agent. The more you teach Tan, the more it works like a studio partner instead of a generic model.
04
Skills turn taste into workflow.
The best production moves should not stay trapped in memory, notes, or one-off scripts. Tan is built to make them reusable — so the investment compounds across every project, not just the one where you figured it out.
