Turn chemical PDFs into source-linked molecule packages
Upload patents or papers. MolLens extracts structures, keeps page-level evidence, and exports review-ready PNG, SDF, SMILES, CSV, and an offline reader package.
All export is MolLens' delivery promise: extracted molecules, source PDF, large PNGs, chemistry tables, and a static reader are packaged together.
Real Patent-Scale Benchmark
Validated on 800 patent PDF pages and 8,816 source structures with page, InChIKey, and IOU localization matching.
Every recognized structure is evaluated with source position evidence, so reviewers can jump back to the exact figure.
Outputs are grouped into a review package instead of scattered screenshots.
A complete review loop, not just OCR output.
MolLens keeps the workflow focused: upload source files, inspect extracted structures in context, then export or save the useful chemistry.
Upload
Add one PDF or a batch of PDF/image files from your workspace.
Extract
MolLens recognizes structures and normalizes useful chemistry identifiers.
Review
Click a structure to jump to its source region and inspect the molecule.
Export
Download All as one package or save selected structures into Library.
One All package, everything a chemist needs to review.
All export is the product promise: every extracted molecule, source PDF, large PNG image, chemistry table, and static reader travels together.
Every structure keeps source context so reviewers can jump back to the original page region.
The offline reader.html preserves PDF viewing and structure navigation without needing MolLens.
Save compounds into Library, then continue with structure detail, similarity search, and reference review.
Every molecule arrives with chemistry data and source evidence.
The output is not a loose OCR table. Each structure is packaged with renderable chemistry, normalized identifiers, exact page location, and downstream export formats.
Renderable structure files
MOL and SDF stay attached to the recognized molecule, ready for cheminformatics tools.
Search-ready identifiers
InChIKey and normalized chemistry metadata make every extracted compound easy to export, review, and deduplicate.
Source-level traceability
Page number and highlighted source region keep each molecule connected to the exact figure.
Compound intelligence
PubChem links and detail lookup support quick review without leaving the workflow.
Simple Credits for first-time adoption.
Start with free Credits, then buy more only when you need to process more pages. No subscription is required for launch usage.
Which files can I upload?
PDF, PNG, JPG, and JPEG files are supported, including single documents and batch uploads.
What does All export include?
All export includes source PDF, PNG structure images, CSV, SDF, SMI, and an offline reader.html.
Can I trace molecules back to the source?
Yes. Structure cards and exported readers keep page-level source evidence for review.
Are my files private?
Uploaded files stay in your authenticated workspace. Shared pages are created only when you explicitly use Share.
