Edit, compile, review
Run Compile to produce a PDF from the project. After changing the source, compile again before sharing the result. PDF up to date indicates the preview matches the compiled source; PDF out of date indicates subsequent edits.
Resolve citations
The included engine runs classic BibTeX and additional LaTeX passes to resolve references. Check citation keys and bibliography entries if references remain unresolved. Biber is not included: documents that require biblatex with Biber can produce an incomplete bibliography.
Check imported projects
Compatibility depends on the document classes, packages, fonts, and assets used by your source. The bundled engine is curated; it is not a complete system TeX installation. A template from another editor or publisher may need adjustments before it compiles.
Read the build diagnostics for missing files or unsupported commands. Keep the project's figures and included source files at the paths referenced by the document. External tools that require shell execution are not supported.
Ask for help
If a problem persists, contact support with your app version, device and operating system, the relevant diagnostic, and a small source example that reproduces it. Remove private research content before sharing an example.
