Use Note Formatter to make study notes easier to read without changing their ideas. Paste Markdown or plain text, choose a mode, and inspect the normalized result. The tool is deliberately local and deterministic: it fixes common layout problems such as headings without a separating space, inconsistent bullet spacing, trailing spaces, repeated blank lines, and unsafe HTML preview expectations. It is useful after copying notes from a lecture, cleaning a shared outline, or preparing a draft for a repository. The markdown-cleanup mode combines the routine rules. Heading normalization turns a marker such as #Title into # Title while retaining the heading level. List cleanup standardizes bullet markers and ordered-list spacing. Spacing cleanup trims safely and collapses excessive blank lines without merging meaningful paragraphs. HTML preview shows escaped text rather than executing markup, so a note remains data instead of becoming active page content. If you need a different result, run the relevant mode and compare it with the original. Formatting is not editing. The tool does not correct facts, improve grammar, translate text, infer hierarchy, or decide whether a note is complete. Keep a copy of the original when the source is important, especially if indentation carries meaning in a code sample. Review fenced code, tables, links, and nested lists after formatting because a general cleanup rule cannot understand every Markdown dialect. When a note contains intentional spacing, choose a narrower mode or preserve the source unchanged. A reliable workflow is simple: save the original, choose one mode, review the output line by line, and then copy the accepted result into your notes. Use the formatter as a final layout pass, not as a substitute for proofreading or version control. The predictable output makes it easier to see what changed and to undo a formatting decision.
Review the result before saving it. The formatter changes layout rules, not the substance of your notes.
Modes normalize headings, lists, whitespace, blank lines, and escaped preview text.
The rules are deterministic and local; they do not perform grammar correction, translation, or content generation.
Check the visible layout changes and confirm that meaning, code, and intentional structure remain intact.
Use version control or an original copy when the note is important.
Do not assume general cleanup understands every Markdown dialect.
Do not discard the original before reviewing the output.
The tool does not fact-check, translate, proofread, or generate content.
Nested lists, tables, and code may need manual review after normalization.
#Title → # TitleHeading levels remain unchanged while a missing separator is added.
marker + inconsistent spaces → marker + one spaceBullet and ordered list layout becomes predictable.
Markdown text → escaped display textPreview content is not executed as HTML.
Formatting stays local and deterministic.

mixed note
Draft note
The selected deterministic rule changes spacing or Markdown structure while keeping the note meaning.
Formatting is local and predictable; the tool does not rewrite ideas or execute HTML.
It applies heading, list, trailing-space, and blank-line cleanup together.
A heading receives one space after its hash marks.
Bullet markers receive consistent spacing and ordered list spacing is normalized.
Repeated whitespace and blank lines are safely reduced.
It displays escaped text without executing HTML.
No. The deterministic rules target formatting only.
No. It returns a local result for the current run.
No. It formats supplied text and does not invent or edit ideas.
