What is Masky and what does it do?

Masky is an AI avatar platform built for creators and developers. You create an avatar with a face, a voice, and a personality, then take it live on stream, in OBS, in the web app, or straight from Claude through API and MCP. In plain terms, Masky helps you turn a character into something that can talk, react, and show up where your audience already is.

What Masky is

Masky describes itself as “one ecosystem for AI avatars.” Each avatar starts with a still image, a personality prompt, and a voice. You start a conversation, inject turns, and the avatar renders spoken responses. That makes it more than a static video tool. It is built for interactive talking-head characters that can stay in character over time.

For creators, that means your avatar can feel like a real co-host instead of a one-off clip. For developers, it means you can drive the same avatar behavior through an API, through Claude, or through live streaming surfaces.

Masky also supports persistent, scoped avatar memory. The docs describe sandboxes and bring-your-own-key backends, so memory can stay tied to the right avatar or tenant. That matters when you want a character to remember names, running jokes, or prior conversations without mixing everything together.

What you can do with it live

Masky’s flagship creator use case is the live Twitch co-host. Creators use avatars that can:

read and respond to chat
thank new follows and subs
run polls
co-host with you on stream

You can bring that avatar into OBS using a browser source and the conversation live-embed URL. You can also use Masky’s cloud streaming setup to stream straight to Twitch.

That gives you a few clear workflows:

Solo stream with an AI sidekick: your avatar watches chat and jumps in when needed.
VTuber-style co-host: your character sits beside you and reacts in real time.
Interactive show format: the avatar handles polls, shoutouts, and audience prompts.

The key point is simple: Masky is built for live interaction, not just generated clips.

How developers use Masky

Masky is also a developer platform. It has an HTTP API at https://masky.ai/api, docs at https://masky.ai/api/docs, and a Masky MCP server for Claude. The docs are curl-first, and the same capabilities are exposed as native Claude tools through MCP.

To get started, you sign in at masky.ai/developer, generate an API key, and copy the mky_... token. You send it on every request like this:

Authorization: Bearer mky_...

The API behaves differently for images and videos:

Images return synchronously in a few seconds.
Videos return asynchronously. A POST gives you a 202 with a generationId, then you poll GET /api/videos/{id} for roughly 1–3 minutes.

That makes Masky practical for both real-time tools and background generation jobs.

Login with Masky

Masky is not only for avatar output. It also acts as an OAuth 2.0 identity provider.

With Login with Masky, a third-party site adds a “Login with Masky” button. The user signs in and picks which of their avatars represents them on that site. The avatar’s name and photo become the identity that the site receives.

That opens up useful product ideas:

fan communities where people sign in as their avatar
creator tools with avatar-based profiles
games, events, or social apps that want a character identity layer

It is a neat fit if you want identity to feel playful, visual, and avatar-native instead of just email-and-password.

Plans and access

Masky is a freemium product with four plans:

Free
Viewer
Creator
Pro Creator

Higher tiers add more capability, with 24/7 Priority Support and dedicated mentor access on Pro Creator.

You can sign in with Twitch or Google at masky.ai.

Who Masky is for

Masky is built for two main groups:

Twitch streamers, VTubers, and creators who want interactive AI characters with zero code
Developers who want to control avatars through API, MCP, or embedded live surfaces

If you want a character that can answer chat, remember context, appear on stream, and also plug into your app, Masky is aimed at that workflow.

The short version

Masky is an AI avatar platform that lets you:

create an avatar with a face, a voice, and a personality
take it live on stream, in OBS, in the web app, or from Claude
build live co-hosts that read chat and react in real time
use an API, MCP, and OAuth identity layer for third-party apps

If you are building around AI characters, Masky gives you the creation tools, the live surfaces, and the developer plumbing in one place.
