Select the root .tex file: the file that sets up the document and includes its chapters. The app follows active \input, \include, and figure references, renames figures in document order, and creates a portable project copy with updated paths. For a multi-file project, approve access to the folder containing the root document.

It finds duplicate citation keys, possible duplicate references with matching DOI or normalized title and year, missing common fields in original .bib entries, and DOI format issues. Possible duplicates are warnings for you to review; matching titles can also belong to distinct works or versions. Checks run on your Mac and do not modify the bibliography. DOI checks do not verify a reference online, and common-field checks are not a guarantee that a journal's style requirements are met.

Yes. Expand View reference or Compare references to see the related entries inside the app, including available title, authors, year, publication details, DOI, source file, and line. The original entry is also available to read. Checking and previewing references is free; saving a report uses one of your free saved exports unless you have unlimited access.

Yes. Open a .bib, a traditional BibTeX or BibLaTeX/Biber .bbl, or a .tex with embedded references or literal \bibliography or \addbibresource links. For linked files, approve access to their folder if macOS asks. If the source bibliography is unavailable, the app can use a matching .bbl beside the TeX file. Compiled bibliographies omit some original fields, so the app reports limited check coverage rather than treating omitted fields as errors. Use the original .bib for common-field checks.

Health Check reads the selected .tex file and the bibliography files named there; it does not follow \input or \include into chapters. Open the TeX file that declares your bibliography, or open the .bib or .bbl directly. Figure Organizer and Submission Packager do follow included chapters for their project checks.

The tools share an allowance of three successful saved exports. Saving a health report counts as an export. Cancelled saves and failed exports do not count, and ordinary app updates do not reset the allowance. Bibliography health checks, original-reference previews, and Word Counter remain free after you use the allowance. Lifetime Premium is a one-time purchase for unlimited saved exports and previews of processed output before saving, with no subscription. Free users can review processed output after a successful save.

Yes. All files are processed locally and your manuscripts, bibliographies, and figures are never uploaded. You can optionally enable online lookup for journal names missing from the built-in list; only the unmatched journal name is sent, and formatting continues normally when offline.

The app supports LaTeX manuscript files (.tex) and bibliography files (.bib and .bbl). It can organize common image formats used by LaTeX, including PDF, EPS, PNG, and JPG, as well as TeX drawing sources loaded as figures.

Check that you selected the root document, the referenced file exists, and its spelling, extension, and letter case match. A relative path is interpreted from the TeX source that contains the reference. Also make sure the reference is active rather than inside a comment and that the app has access to the project folder.

Yes. When figure content loads a TeX drawing with \input, Figure Organizer and Submission Packager treat that drawing as a figure dependency. When figure renaming is enabled, the exported drawing receives an ordered figure name. Its surrounding reference is updated to the exported path.

Both routes prepare the same project-aware submission package. Folder export writes the result to a directory you choose, while ZIP export creates an archive ready for upload. Included TeX sources, figures, bibliography files, and discovered local support assets are kept in the package.

A document that declares backend=biber must use Biber rather than BibTeX. In TeXShop, open the root main.tex, select pdflatexmk as the engine, and typeset. Latexmk will run the required LaTeX and Biber passes automatically.

Only a journal name that was not matched by the app's built-in list is sent to the lookup service. Your bibliography file, authors, titles, and other fields remain on your Mac. Turn the option off to keep journal formatting fully offline.

Open the Premium window and select Restore while signed into the same Apple Account that made the purchase. Restoring does not charge you again. Lifetime Premium purchases retain unlimited exports. Original paid app purchases are recognized using Apple's verified original app version and acquisition date during the paid release period. Earlier free downloads do not automatically unlock Premium, even if you later updated to a paid release. If you paid and access is missing, contact support so we can help.

Tell us which tool you used, the steps that led to the problem, what you expected, what happened, and the exact message shown. The app can prepare an email with its version, build number, and macOS version. It never attaches your document or diagnostics automatically.
