Frequently Asked Questions

Add-on (inside Google Docs)

Q. The equation image looks blurry in my document. A. The Add-on inserts a PNG image sized to match standard inline/display text height. If you need a larger image, try scaling it after insertion using Google Docs’ image resize handle.

Q. My LaTeX formula shows an error in the preview. A. The preview uses Temml to render your formula. Check your LaTeX syntax — common issues include missing closing braces } or unsupported commands.

Q. The Scan tab didn’t find my formulas. A. The scanner detects four delimiters — $...$ (inline), $$...$$ (display), \(...\) (inline), and \[...\] (display). A separate bracket mode also finds [ ... ], for display math whose backslashes a chat app stripped; it is off by default, so tick Also detect [ … ] in the panel before scanning if you need it. Make sure your formulas use one of these delimiters and are not inside special objects like drawings or images.

Q. How do I turn off data collection in the Add-on? A. Go to Extensions → LatexFlow → Data Collection Settings in Google Docs. You can withdraw consent at any time. See our Privacy Policy for details.

Web app (mathsystem.dev/latexflow/web/)

Q. What Google Drive access does the Web app get? A. Only the limited drive.file scope — it can see only the files you explicitly pick in the Drive Picker, and it cannot list, search, or read anything else in your Drive. See the Privacy Policy for details.

Q. My .docx upload fails or some equations are missed. A. The scanner detects $...$, $$...$$, \(...\), and \[...\]. A fifth bracket mode additionally picks up [ ... ] — display math whose backslashes a chat app stripped — and it is on by default; untick it if plain brackets get picked up. Equations split across multiple paragraphs are not currently detected — keep each $$...$$ on a single paragraph if possible.

Q. The scan found 0 equations. What now? A. The result screen first reports what was actually read — Scanned N paragraphs · 0 equations found — and then walks you through the fix: the same line shown before and after delimiters are added, plus every delimiter that works. If the file holds Word equation objects, it says how many; those are not text, so no delimiter can reach them and that math has to be retyped or pasted back in as LaTeX text. Paragraphs that look like math but carry no delimiter are listed above the guide — open one, wrap the math in $...$ or $$...$$, and the live preview confirms what gets detected. Try another file reopens the file picker.

Q. How do I recover the original LaTeX from a rendered image? A. Each PNG includes the original LaTeX in its alt-text (AIMATH_FORMULA::v1:: tag). You can recover the source for any equation from the image’s alt-text field in Word or Google Docs.

Q. How do I turn off data collection in the Web app? A. The Web app sends only the equation source and rendered PNG (no other document content) to our collection endpoint. An in-app toggle is on the roadmap; in the meantime, email sung2417@gmail.com and we will arrange an opt-out for your account.
