Kaitoi is a self-extending AI platform for creators and developers. Kaitoi Studio is the browser workspace where you build and run workflows, Kaitoi Core is the platform and API underneath it, and Penny is the assistant that works alongside you and builds the capabilities you are missing, right inside the workflow.

Kaitoi is in open beta, with no waitlist. Create an account at studio.kaitoi.io and claim your free starter credits. Building is free, and so is running anything that does not call a paid model or provider. If your team wants help bringing Kaitoi into a real production, get in touch.

Penny is the assistant built into Kaitoi. Describe what you need in plain words and Penny finds the right nodes, builds and runs the workflow, and writes a new node when the one you need does not exist yet. In Lab, Penny works on a moodboard: you talk, and images, video, audio and 3D land on the board. You choose which language model runs Penny, and its turns come out of your credits like any other model call.

Most software ships with a fixed feature list. Kaitoi is built from composable nodes, so when a capability is missing, Penny can write a new node for it, including one that calls an outside API, or custom Python that runs inside the same workflow system. The Kaitoi CLI can also turn a GitHub repository or Hugging Face model into a recipe that runs on your own machine.

Kaitoi is built for studios, agencies, production teams, technical artists, creative technologists, researchers, educators, and developers building AI-native workflows. It is designed for teams that need creative flexibility, deterministic execution, and the ability to integrate custom tools.

Kaitoi Studio is the browser workspace: node graph, Lab, storyboard, timeline and media tools, with Penny throughout. Kaitoi Core is the platform underneath: the execution engine, sandboxing, model providers, storage, the public API and the MCP server. The Kaitoi CLI brings Kaitoi to your terminal. It runs open models on your own hardware, connects ComfyUI, Ollama, Blender and any local tool with a REST API to your graphs, and includes Kaitoi Code, Penny for your code repositories, and Crew, a team of agents that plans, builds, tests and reviews an application for you. The CLI is a free download. Kaitoi Code and Crew come with the Indie plan and up, and using your local models and tools in your graphs comes with the Studio plan.

Kaitoi supports workflows across images, video, audio, text, 3D, documents, web apps, vector graphics, structured data, simulation, research, and custom Python logic. A workflow can combine generative models with deterministic steps, APIs, local tools, and team-specific automation.

No. Lab is a moodboard you can talk to, made for early ideas. The same project can grow into storyboards, graph prototypes and repeatable production pipelines as the work matures.

Yes. Publish the project as a Station: a small app at its own link. You choose which inputs people can set and which outputs they see; they get a simple form, a preview of the result and a private history of their own runs. They sign in with a free Kaitoi account to run it, and each run comes out of their own credits, not yours. A Station is a frozen snapshot, so it changes only when you publish a new version, and you can take it down at any time. Every plan can publish Stations. If a Station uses nodes of your own, only people you invite by email can run it, and one with nodes you wrote by hand needs the Studio plan.

Not necessarily. Kaitoi is designed to connect models, APIs, local systems, and production tools into one workflow layer. It can generate assets directly, but it can also sit alongside existing editors, render tools, local models, and internal studio infrastructure.

Building is free, and so is running anything that does not call a paid model or provider. Penny runs on a language model, so its turns come out of your credits too. When a run calls a paid provider, it is charged at exactly the provider's price, with no Kaitoi fee on top, itemized per run and per provider. One credit is one US cent. Pay-as-you-go is the free plan: no subscription and no monthly minimum, and you top up whenever you need more credits.

Subscriptions add capabilities, not a better rate. Indie adds monthly credits that roll over, your own API keys, publishing nodes and templates to the community, the public API, MCP, and Kaitoi Code and Crew in the Kaitoi CLI. The Studio plan adds team workspaces with a shared balance, workflows published as API endpoints, writing node code by hand, local integrations, and priority support with a 24-hour response. Enterprise is for larger organizations that need custom credits and dedicated support: contact us.

Yes, from the Indie plan up. With your own key, the provider bills you directly, at the same per-run price.

Teams come with the Studio plan, which is priced per seat with a minimum of two seats. A team shares projects and one pooled credit balance. Each member has a role: owner, admin, editor or viewer. The owner can set a weekly spending cap on any other member, and admins can cap editors and viewers. Every run is attributed to the person who ran it.

Yes. Owners, admins and editors run work from the team's shared balance, within any weekly cap set for them. Viewers can see the team's projects but cannot spend. The team owner can top up the team balance at any time.

More than 1,500 generative models for image, video, audio, 3D and more, including Veo, Kling, Seedance, Nano Banana, GPT Image, Flux, ElevenLabs and Tripo. On top of those, around 400 language models: OpenAI, Anthropic and Google directly, and the rest through OpenRouter. When a provider releases a new model, you do not have to wait for us: Penny can turn it into a working node. You can also run open models on your own hardware with the Kaitoi CLI.

Kaitoi Studio runs in the browser, on desktop and mobile, and runs your workflows in Kaitoi's cloud. With the Kaitoi CLI and the Studio plan, your graphs can also reach your own machine: turn a whole ComfyUI workflow into a single node, run Blender scripts as nodes, use local Ollama models, or plug in any local tool with a REST API. Open models from GitHub or Hugging Face can run locally too. Ollama's cloud models also come with the Studio plan and need only your Ollama key, not the CLI. An open source version of Kaitoi that runs entirely on your own machine is coming soon.

Yes. On every plan, Penny can write a new node for you when the one you need does not exist. Nodes are Python, and a node can carry its own interface. The public API and MCP start at Indie. Writing node code by hand, local integrations, and publishing a workflow as an API endpoint come with the Studio plan. Each extension runs as its own contained unit with defined inputs and outputs, so adding tools does not turn the system into one fragile codebase.

Yes to both, from the Indie plan up. The public REST API lets you build your own product on Kaitoi, and the documentation is public. Kaitoi is also an MCP server: connect Claude Code, Codex or any other MCP client to your workspace to run nodes and graphs, edit projects and bring results back. Writing new nodes over MCP needs the Studio plan. Penny can also use tools from MCP servers you connect. On the Studio plan you can publish a workflow as its own endpoint with typed inputs.

Kaitoi combines AI with deterministic code. That means a workflow can include generative steps, exact calculations, simulations, file operations, APIs, validation, and custom logic in one graph. Kaitoi Studio is built for creative production, but the pattern is broader: if a domain needs a mix of AI, exact logic, files, APIs, and repeatable execution, Kaitoi can help turn that into working software.

We never train models on your work, and we never sell it. You keep ownership of your content. Projects and outputs are stored in Kaitoi, separated by account and team. When a node calls a third-party provider, your prompt and assets go to that provider under its terms, and Kaitoi shows which provider handled each run. Using your own key changes whose account the run uses, not whether the provider sees the data. You can delete your own projects and files. To delete your account, email privacy@kaitoi.io.

Use Report a problem inside Kaitoi, join us on Discord, or email support@kaitoi.io. A bug report we can reproduce, feedback that changes what we build, or a community node other people use can each earn you credits. The Studio plan includes priority support with a 24-hour response.
