Importing Content

Corca allows you to bring existing work into the editor from a variety of formats. This includes LaTeX documents, Markdown files, exported notes from tools like Notion, complete project archives, and images containing math or text. Importing is designed to preserve structure, math, formatting, and media whenever possible.

Most imports happen automatically. You provide the file, and Corca converts it into an editable document.

Supported import formats

You can import content from several sources.

ZIP archives are processed only if they contain supported files such as .tex or .md.

Images inside an archive are imported only when they are referenced from a LaTeX or Markdown file.

Importing a file

You can import files directly into your workspace.

Method 1 — drag and drop

Drag a file into the document tree in the left sidebar. Supported files:

• .tex

• .md

• .zip

• .tar.gz

• image files

The file uploads and a new document appears automatically.

Method 2 — using the Import button

• Click Import in the left sidebar.

• Select one or more files.

• The documents are created in the current folder.

Where imported documents appear

Imported documents are created in the currently selected folder. If no folder is selected, the document is created at the root level of the workspace.

Importing LaTeX

LaTeX is the primary format for mathematical documents. Corca converts LaTeX into native math expressions and structured content.

After import, the content behaves like any other document. You can edit equations, rearrange structure, and continue working immediately.

LaTeX input:

x^2 + 5x + 6 = 0

Becomes x2+5*x+6=0

LaTeX input:

\frac{d^2 f}{dx^2}

Becomes d2(ƒ)/(d(x)2)

LaTeX input:

\iint x , dx , dy

Becomes ∫((∫_^)(x,d(x),d(y)))

Importing a full LaTeX document

You can import an entire .tex file. The importer processes:

• sections

• math expressions

• tables

• figures

• references

• formatting

• images referenced in the document

• TikZ diagrams contained inside the LaTeX source

Importing Markdown

Markdown documents can be pasted or uploaded. The importer converts formatting automatically.

Supported Markdown elements

Importing Notion exports

The recommended workflow:

1. Export your Notion workspace as Markdown + ZIP

2. Upload the ZIP file into Corca as described above

The importer preserves:

• document structure

• nested folders

• images

• formatting

• code blocks

Importing from Overleaf

1. Download your project from Overleaf as a ZIP file

2. Upload the ZIP file into Corca

The importer converts the project into editable documents.

OCR — importing from images

OCR (Optical Character Recognition) allows you to extract text and math from images.

This works with:

• handwritten notes

• textbook pages

• scanned worksheets

• screenshots

• whiteboard photos

Instead of retyping content, you can convert the image directly into editable math.

Recognizing text from an image

After inserting an image into the document, you can run OCR.

Step 1 — insert or paste an image by drag-and-drop or taking a screenshot and press Cmd /Ctrl+V.

Step 2 — click the image

Step 3 — click Recognize at the bottom right corner of the image.

Corca analyzes the image and inserts the recognized content below it.
