Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
15 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by mirage-hq on GitHub. Read the source before you install it.

Installation

Install the Tesseract Editor AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/mirage-hq/Tesseract/tree/main/skills/tesseract-editor
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/mirage-hq/Tesseract.git /tmp/Tesseract
mkdir -p .claude/skills
cp -r /tmp/Tesseract/skills/tesseract-editor .claude/skills/tesseract-editor

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Tesseract Editor in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Tesseract Editor on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Tesseract Editor is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Build a Tesseract editor

If the editor needs to import or export other tools’ project formats, such as Premiere Pro or After Effects, read conversion. When opening shared or older .tsrct files, updating tools, or investigating load/render differences, read versions and compatibility.

The browser engine opens, previews, edits, and saves .tsrct projects locally. A static HTML application is sufficient; no backend or native CLI is required. The browser runtime does not export video.

The browser API reference covers initialization, actions, playback, and saving. Examples: general layer controls and controls for a bundled project.

Runtime and serving

references/cli-version.txt, when present, pins the browser runtime release too. The installation reference identifies the release repository. The browser assets are tesseract-<VERSION>-web.zip and its .sha256; verify the checksum before use. The archive contains runtime/, used beside index.html in the examples. Its generated JavaScript, types, and WASM must come from the same release. No npm installation is needed. version() returns the runtime release.

The editor needs HTTP serving and browser GPU/media support. Its HTML depends on the runtime files; attachment viewers may not execute WASM. CLI or skill updates do not require upgrading an existing editor’s runtime.

Editing and saving

actionSchema() describes supported engine actions. UI controls, playback scheduling, and selection gestures belong to the application. Await rendering so frames do not overlap; edit groups combine continuous changes into one history entry.

TesseractEngine.create(file) accepts a File or Blob. toBlob() packages the current document with its original assets; it does not write to disk. Overwriting the source file can invalidate asset reads; the API reference describes reopening the saved Blob. Page refresh discards unsaved edits.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Tesseract Editor AI skill do?

Build or modify a custom browser editor for Tesseract .tsrct files. Use for editor controls, previews, and saving projects; use the motion or video skill for direct project authoring.

Why use Tesseract Editor on TypingMind?

Because you install it once and use it with any model. Tesseract Editor is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Tesseract Editor in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/mirage-hq/Tesseract/tree/main/skills/tesseract-editor. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Tesseract Editor?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Tesseract Editor?

As many as you like. As long as a model supports skills, you can use Tesseract Editor with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Tesseract Editor AI skill free?

It is published on GitHub by mirage-hq. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
