TeXBB is a local-first workspace for LaTeX, Markdown, drawing, and references on Windows. The Android app is a companion viewer for reading synchronized Markdown previews and compiled LaTeX PDFs.
Get started on Windows
- Install TeXBB from the Microsoft Store.
- Choose LaTeX or Markdown from the mode bar. Use the + button in that mode's toolbar when you want another numbered document.
- Write your note, then select Save. Your source files remain in your local TeXBB workspace.
Build and preview your work
- LaTeX: select Build to compile the active document and open the fresh PDF.
- Markdown: select Build to open the rendered preview for the active Markdown document.
- Blackboard: choose a color and line width, draw or paste an image, and select Save when finished.
- Reference: open your configured BibTeX library, edit the entries, and select Save. Open Settings → Reference, then select Change File... to choose a different BibTeX file.
Connect the Android companion
- Install TeXBB on both your Windows PC and Android phone. Keep both devices on the same trusted private network while pairing or synchronizing.
- On the PC, open Settings → Mobile Viewer and turn on Connect with phone.
- Open TeXBB on Android and scan the connection QR code shown by the PC app.
- Select Sync on the phone to receive rendered Markdown documents and the latest successfully built LaTeX PDFs. The most recently verified copy remains available for offline reading.
See the illustrated PC–Mobile Connection Guide on the TeXBB home page.
Common fixes
- The phone does not show recent changes: save the Markdown document or select Build to successfully rebuild the LaTeX PDF on the PC, then select Sync again.
- Pairing does not complete: confirm that both devices are on the same trusted private network, keep TeXBB open on the PC, turn on Connect with phone, and scan a newly displayed connection QR code.
- A LaTeX PDF does not build: check the build output for the first error and confirm that a supported TeX compiler is available on the PC.
- The PC is offline: previously synchronized files remain readable on the phone, but new changes require the PC to be available for another synchronization.
Contact support
Email texbb@kiyuobjung.com with the TeXBB version, the device and operating-system version, what you were trying to do, and the exact error message. A screenshot is helpful, but remove private documents, QR codes, connection addresses, and credentials before sending it.
