Small, focused, free, open-source. Each one exists because a specific export/migration format is documented as broken and nothing else fixes it well.
notion-unbroken Cleans up raw Notion exports — strips UUID-suffixed filenames, fixes broken internal links and image paths, converts HTML callouts/toggles to markdown, and turns database CSVs into Dataview-ready Obsidian notes.
roam-unbroken Converts Roam Research JSON exports into clean Obsidian markdown — fixes Roam's italic syntax (which silently becomes bold in standard markdown), resolves cross-page block references and embeds, and keeps TODO/highlight formatting intact.
epub-a11y-fix Audits and remediates EPUB accessibility metadata — missing language tags, missing alt attributes, missing schema.org accessibility metadata, missing navigation landmarks. Never fabricates content it can't know (real alt text, accessibility summaries) — those always stay flagged for human review.
