Stop manually retyping equations from academic research PDFs. Highlight any equation block to instantly generate clean, Overleaf-ready LaTeX code locally.
Built for confidential workflows — files stay in your browser memory.
Generic OCR treats a matrix as a bag of characters and often mangles subscripts, fraction bars, and summation limits. GoLocalPDF’s local math pipeline segments equation regions by spatial hierarchy: operators, nested radicals, multi-line align environments, and Greek glyphs are reconstructed into compilable LaTeX (including amsmath-style arrays). Because recognition and tokenization run in your browser via WebAssembly workers, unpublished drafts, grant proposals, and patent formulas never touch a third-party OCR API—useful when Mathpix-style quotas or cloud training policies are unacceptable.
Graduate students rebuild literature-review equations into Overleaf notes without retyping. Instructors convert textbook problem sets into homework templates. Chemists and physicists extract reaction schemes and integral identities from scanned lecture PDFs. Labs preparing camera-ready supplements use the tool offline on air-gapped research machines where cloud OCR is banned.
Drop a journal page, thesis excerpt, or textbook scan into the browser sandbox—no account required.
Select the formula block; the client engine maps bounding boxes before symbolic parsing.
Preview the markup, then paste into Overleaf, TeXstudio, or your paper repo.
| Feature Metric | Traditional Cloud Services | GoLocalPDF Sandbox |
|---|---|---|
| Matrix & fraction fidelity | ❌ Collapses grids; breaks \frac and array structure | ✅ Hierarchical symbolic segmentation into amsmath-compatible LaTeX |
| Research confidentiality | ❌ Equations sent to cloud OCR / model vendors | 🛡️ 100% on-device WebAssembly—no equation telemetry |
| Usage limits | ❌ Page caps and paid Mathpix-style quotas | 🆓 Unlimited local extractions limited only by device memory |
| Editor readiness | ❌ Needs heavy manual fix-up before compile | ✅ Markup aimed at direct Overleaf / TeX compile |
The local engine groups glyphs by row/column alignment and nesting depth, then emits LaTeX array or align-style structures instead of a single flattened text line.
No. Parsing and OCR run in browser memory. Nothing is uploaded to GoLocalPDF servers for formula extraction.
For many equation-extraction workflows, yes—you get local, unlimited conversion without a SaaS OCR subscription, though extremely exotic notation may still need a quick manual tweak.
Common Greek letters, operators, and many chemistry notations are mapped into standard LaTeX macros during symbolic reconstruction.
Yes. After the page loads, equation extraction is designed to run client-side; disconnect the network to verify no upload traffic for the local path.
