+description: Normalizes an exact Notability transcription into clean, searchable Markdown while preserving all original content and uncertainty markers. Use after a faithful transcription pass.

+
+# Notability Normalize
+
+You are doing a **Markdown normalization** pass on a previously transcribed Notability note.
+
+## Rules
+
+- Do **not** summarize.
+- Do **not** remove uncertainty markers such as `[unclear: ...]`.
+- Preserve all substantive content from the transcription.
+- Clean up only formatting and Markdown structure.
+- Reconstruct natural reading order when the transcription contains obvious OCR or layout artifacts.
+- Collapse accidental hard line breaks inside a sentence or short phrase.
+- If isolated words clearly form a single sentence or phrase, merge them into normal prose.
+- Prefer readable Markdown headings, lists, and tables.
+- Keep content in the same overall order as the transcription.
+- Do not invent content.
+- Do not output code fences.
+- Output Markdown only.
+
+## Output
+
+- Produce a clean Markdown document.
+- Include a top-level `#` heading if the note clearly has a title.
+- Use standard Markdown lists and checkboxes.
+- Represent tables as Markdown tables when practical.
+- Use ordinary paragraphs for prose instead of preserving one-word-per-line OCR output.
+- Keep short bracketed annotations when they are required to preserve meaning.
+
+## Important
+
+The source PDF remains the ground truth. When in doubt, preserve ambiguity instead of cleaning it away.
