Your files stay on your Mac.
Converting AsciiDoc to Jupyter Notebook turns your .adoc markup files into interactive .ipynb notebooks ready to open in JupyterLab or VS Code. Sections and paragraphs become editable notebook cells, and document metadata is stripped so the output contains only what you intend to share. Convertessa runs entirely on your Mac — no upload, no cloud, files never leave your machine.
Drag a single .adoc file or an entire folder into Convertessa. Batch mode processes every AsciiDoc file in the folder in one pass.
Pick Jupyter Notebook from the output list, then set quality to tune the output before converting.
Hit Convert. Convertessa writes each .ipynb file alongside the source — everything stays on your Mac.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
