About Pencil AI

Pencil is a design canvas that works directly inside the code editor, eliminating the need to switch between Figma and the IDE and endlessly hand off mockups from designer to developer. With a tab open, you draw pixel-perfect interfaces and then immediately write code — all in one place and in one repository.

The tool works as an agent-oriented MCP canvas with an open file format. Design is stored in your repository, versioned through Git, and can be read, edited, or extended with your own tools — with no black boxes and no lock-in to a single service. Inside, there is an infinite canvas where you can prompt entire screens or individual elements right in context. Pencil supports Cursor, VSCode, Claude Code, OpenAI Codex, and any other IDE, and design and code always remain synchronized.

Who is Pencil AI for?

For interface developers

The tool is built for developers who prefer to design and write code in a single environment. Thanks to the open format and Git versioning, the design is easy to control and extend with your own tools.

For designers working alongside code

Designers who need to bring layouts over from Figma without losing quality will appreciate the ability to copy and paste vectors and styles, as well as work with design kits and their own design systems directly from the codebase.

For teams without a design-development split

The platform suits no-code and low-code specialists who want to create and manage interfaces in one place, connecting AI agents for parallel work.

How to use Pencil AI?

Start a session in your code editor

Open the Pencil tab inside Cursor, VSCode, Claude Code, or another IDE. The design canvas appears right in your working environment, so no separate apps or file transfers between services are needed.

Prompt screens and elements

Use the infinite canvas to prompt entire screens or individual elements in context. For quick ideas, you can sketch entire flows or generate several screen variations in parallel by connecting AI agents that work alongside you.

Connect data sources and import layouts

Set up two-way MCP access to not only read but also write data from databases, APIs, charts, Playwright, Puppeteer, or other agents. If you already have layouts in Figma, simply copy and paste them — vectors and styles will be transferred without loss.

Key Features of Pencil

Design canvas inside the code editor

An infinite pixel-perfect canvas where you can create interfaces and immediately write code without leaving the IDE or switching between services.

Connecting AI agents for parallel work

The platform lets you bring in AI agents that work like a team of extra hands, helping you quickly sketch flows or generate multiple screen variations at once.

Figma import and design system use

Figma layouts can be copied and pasted without losing quality, including vectors and styles. Ready-made design kits are available, and you can also connect your own design system from the codebase.

Two-way MCP access to data

It supports not only reading but also full writing of data from databases, APIs, charts, Playwright, Puppeteer, and other agents, along with a set of handy tools for working with the canvas.

Benefits of Pencil

A unified workspace

Design and code live under one roof, in a single repository, and always stay in sync. This eliminates the back-and-forth transfer of layouts between designer and developer.

Open format and versioning

Design is stored in an open format, versioned through Git, and can be read, edited, or extended by external tools — with no lock-in to a single service.

Integration flexibility

Two-way MCP access to databases, APIs, and other sources, plus compatibility with several popular IDEs, gives you full control over the process.

Disadvantages of Pencil

No explicit disadvantages of the tool are listed in the source data. Only general limitations related to the distribution model are noted: pricing and access terms are not disclosed in public sources, so the implementation budget cannot be objectively assessed. In addition, effective use requires a certain level of familiarity with code editors and Git.

What tasks does Pencil solve?

Creating interfaces without a separate design tool

Pencil lets you draw pixel-perfect interfaces right in the code editor, removing the need to keep Figma and an IDE open side by side.

Fast generation of screen variations

With prompting and connected AI agents, you can quickly sketch flows or generate several screen variations in parallel.

Keeping design and code in sync

The tool solves the problem of design-code mismatch: both live in the same repository, are versioned through Git, and automatically remain aligned.

Pencil Pricing

The provided source data contains no pricing information for Pencil. Subscription plans, pricing, and free access terms are not disclosed in the sources used, so the exact cost cannot be estimated.

Pencil Terms of Use

No information about Pencil's terms of use is available in the source data. Registration requirements, licensing restrictions, privacy policy, and rules for using the open file format are not specified. For current terms, you should refer to the official documentation at trypencil.com.

Pencil Availability

The platform works with popular code editors, including Cursor, VSCode, Claude Code, OpenAI Codex, and any other IDE of your choice. Design is stored in an open format in the repository, ensuring portability across environments. Exact data on available regions and supported languages is not disclosed in the source materials.

How Pencil Differs from Alternatives

The main difference between Pencil and traditional design tools is that it works directly inside a code editor. Instead of a separate service with its own storage, it uses an open format with Git versioning, allowing the design to be read and edited by external tools without being tied to a single platform. The tool also stands out with two-way MCP access: it not only gets data from databases and APIs but also fully writes it, and connecting AI agents enables parallel collaborative work on the canvas.

Conclusion

Pencil is a design canvas integrated into a code editor that brings interface design and development together in one repository. The open storage format, Git versioning, lossless Figma import, and two-way MCP access to data make it a flexible tool for developers, designers, and no-code teams. The platform supports connecting AI agents for parallel work, which speeds up interface creation, and compatibility with popular IDEs lowers the barrier to adoption. Despite the lack of information about pricing and terms of use, Pencil looks like a reasonable solution for those who want to keep design and code under one roof.
