Synthesia's ChatGPT plugin generates, revises, and automates AI avatar videos inside the chat — a conversational mode for marketing video and a Studio mode for word-exact training content.

Synthesia for ChatGPT is a plugin, announced November 3, 2026 and available on every Synthesia plan, that connects Synthesia — the enterprise AI avatar-video platform — to ChatGPT. Instead of switching to Synthesia's own editor, you describe a video inside ChatGPT and the plugin generates it with an avatar, voiceover, and supporting visuals, then lets you revise it in the same conversation. You can also search your existing Synthesia video library from the chat. For the launch framing see the [Synthesia ChatGPT plugin news](/news/synthesia-for-chatgpt), and for the scored verdict see the [Synthesia for ChatGPT review](/reviews/synthesia-for-chatgpt).
ChatGPT gathers a few details first — it asks about visual style and length — then hands the brief to Synthesia. There are two levels of control. The default conversational mode is built on [Syren](/ai-tools/synthesia-siren), Synthesia's prompt-to-video agent, aimed at fast, designed output — explainers, how-tos, launch videos, marketing — combining motion graphics, avatars, voiceover, music, and b-roll, all revised by chatting. Specify Studio in the prompt and an avatar delivers your script word for word with brand kits and templates, openable in Synthesia's editor for scene-by-scene edits, suited to training, onboarding, and compliance.
The plugin also automates production. Because it sits alongside ChatGPT's other connected tools, a video can be triggered without opening a chat — a workflow runs once, on a schedule, or when new material arrives in a connected app. Synthesia's examples include turning a Slack product-release post into a 30-second launch video. To connect, open ChatGPT's Plugins menu, search Synthesia, and click Connect (you can create a free account inline); Synthesia also documents an MCP-server route that covers both ChatGPT and Claude.
Synthesia published availability ("every plan") but not specific per-plan limits or per-video pricing for the plugin, and its video generation historically runs against plan-level caps with watermarks on free output. Treat the specifics as a launch snapshot and confirm current limits on synthesia.io.
The plugin's strength is narrow and real: it renders one polished, avatar-led video from a chat brief. Its ceiling is just as real — that video comes out as a single Synthesia clip, in one shape, fronted by a Synthesia stock or Studio avatar, with no captions and no home. [Kompozy](/) is the tool that turns that one clip into a full content set, and it closes the two gaps the plugin leaves most exposed: format breadth and persona ownership.
Format breadth first. A marketing explainer only earns its keep if it shows up as a Reel, a TikTok, a Short, a LinkedIn native clip, and the written posts around them. Drop the Synthesia MP4 into Kompozy's [Clipped Shorts](/glossary/clipped-short) and it reframes the same footage to 9:16, 1:1, and 16:9 with word-synced burned-in captions — so it carries on muted feeds where Synthesia's generated voiceover plays silent. Then, from the same brief, Kompozy generates the formats the plugin can't touch: a brand-exact [Carousel](/glossary/hyperframes), [Quote Graphics](/glossary/persona-tweet), per-platform text, a blog article, and an email newsletter, every piece held to one [Persona Brief](/glossary/persona-brief) voice.
Persona ownership second. Synthesia fronts your video with its avatars; Kompozy lets you front the same idea with your own face through [Persona Shorts](/glossary/persona-shorts) and HeyGen-based formats, so your brand's recurring identity isn't a vendor's stock presenter. Use the plugin where it wins — fast, on-brand avatar video from a chat, or word-exact Studio training clips — and let Kompozy multiply and publish the marketing lane. For the full side-by-side, see the [Synthesia for ChatGPT alternative](/alternatives/synthesia-for-chatgpt) page; for adjacent avatar tools, see [Synthesia](/ai-tools/synthesia) and [HeyGen](/ai-tools/heygen).
It is a plugin, announced November 3, 2026 and available on every Synthesia plan, that connects Synthesia's AI video platform to ChatGPT. You describe a video in the chat and Synthesia generates it with an avatar and voiceover, you revise it in the same conversation, and you can search your existing Synthesia library — all without leaving ChatGPT. It can also trigger videos automatically from other connected tools.
Open ChatGPT's Plugins menu, search for Synthesia, and click Connect (you can create a free Synthesia account during setup). Then start a new chat, tag Synthesia, and describe the video you want; it asks about style and length, generates the clip, and you revise it by chatting. Synthesia also offers an MCP-server route that works with both ChatGPT and Claude.
No. It generates and revises a Synthesia video and saves it to your library; it does not cut it into platform-native vertical shorts, caption it for muted feeds, or publish it anywhere. To take the clip to every feed, pair it with Kompozy, which reframes and captions it, generates matching carousels, text, a blog, and a newsletter, then schedules and publishes them across nine destinations.
Synthesia said the plugin is live on every plan, including free, but did not publish plugin-specific limits or a per-video price. Because Synthesia's generation runs against plan-level caps and free output carries a watermark, the practical cost is governed by your Synthesia plan. Confirm current limits on synthesia.io.
