Prism AI

Prism AI is the second tab in the MCP panel: transcription, beat markers, sound, music, images and editable SVG import, each priced per use in dollars.

The Prism AI collects capabilities After Effects has no native answer for — the kind of work that used to cost an afternoon. Each tool returns real, editable timeline content, not a flat render.

It's one of the two tabs in the MCP panel — see the MCP panel for how MCP and Tools divide the work.

The short version
Purpose-built tools for jobs After Effects can't do on its own.
Nine tools: subtitles and beats from audio, generated sound, music, and images, editable SVG and Lottie import, and a source sweeper.
Every result is native and editable — subtitle layers, real markers, real shapes.

The tools

Nine tools, grouped by what they do. Each links its own page. The tag shows whether it draws on your AI balance (prepaid dollars for the heavy, generative work) or runs free.

Audio

  • Transcribe — turn any audio or video layer into a word-level transcript with precise timestamps. Metered: $0.02 / minute.
  • Subtitles — transcribe a voiceover into a timed, styled subtitle layer. Metered: $0.02 / minute.
  • Beats — detect the beat and drop frame-accurate markers to animate against. Metered: $0.01 / analysis.

Generate

  • Sound — generate a sound effect from a short description and drop it at the playhead. Metered: ~$0.006 / second ($0.18 for 30s).
  • Music — generate original instrumental background music from a mood or style. Metered: $0.45 / minute.
  • Image — generate an image from a text prompt and place it as a layer. Metered: $0.01–$0.12 / image.

Import & rework

  • SVG — bring a logo in as real text and shapes, not flattened outlines. Free.
  • Lottie — import a Lottie JSON animation as an already-moving comp of editable layers. Free.
  • Sweeper — swap a layer's source while keeping its keyframes, effects, masks, and trims. Free.

How you trigger them

Every tool runs two ways: directly from the Prism AI, or by a plain-language prompt to your connected AI. Same tool, same result — the tab needs no AI client at all. Run the tool from the tab, or ask your AI for the result — "transcribe the voiceover and add subtitles," "detect the beat and add markers," or "import this logo as editable layers" — and Prism runs the matching tool and writes the result into your active comp.

1
Open the comp
Make the composition you want to work on the active comp in After Effects.
2
Run it from the Prism AI
Open the Prism AI in the MCP panel and run the tool — most work from your current selection, and some ask for a short description or a file.
3
Or ask your AI in plain language
Describe the result you want — subtitles from the voiceover, beat markers from the music, or an SVG imported as editable layers. Your AI calls the matching Prism tool.
4
Refine the result
What comes back is native — adjust it like anything else, and undo in one step.

Prism MCP

The MCP panel connects your AI client to the live composition and runs its requests as native After Effects work — what it does and how to use it.

One license key

How Prism licensing works: one permanent key per subscription covering every extension, two devices per plan, and a one-time paste to activate the panel in After Effects.
