Paste a DOI and the open-access PDF is fetched and displayed here — nothing is downloaded to your machine.

Statistics
Set Group by above, then the test runs on your raw data and the significance brackets are drawn from the result — not typed by hand.
Charts from your own data
Paste a CSV, pick the columns, and get a vector-quality chart: scatter, line, bar and box plots with error bars, plus linear and four-parameter-logistic fits.
The chart transfers into a panel like any other image.

Import from the web
An image link loads straight away. If direct browser access is blocked, the optional fallback setting may send the requested URL through a relay service. A page URL opens inside the app — click any image on it to pull that image in at full resolution. Images are also listed below as a fallback.

Paste the address of an image — or of the page it sits on — and pull it in at full resolution.
Crop a region, rotate, flip, tune it, cut the background out, then send it to a panel.

CAD & format notes
STEP/STP, IGES/IGS and BREP are tessellated locally in the browser through an OpenCascade WebAssembly importer when used. This is heavier than mesh loading and may take a few seconds.
Fusion 360 / SolidWorks / Inventor / CATIA: native proprietary project files such as .f3d, .sldprt, .ipt or .CATPart are not read directly in this browser-only build. Export STEP/IGES for CAD geometry, or STL/OBJ/3MF/GLB for visualization.
Model resources
Licences and permitted uses vary by model and repository. Check the individual model licence before publication, redistribution or commercial use.
Compose a 3D sceneOpen STL, OBJ, PLY, GLB/GLTF, FBX, 3MF, AMF, DAE, VRML, STEP/STP, IGES/IGS or BREP files. Add several models, move/rotate/resize them independently, style the surfaces and transfer the final view into your figure.

Functional groups
2D groups are drawn with an R attachment point. Switch to 3D and the capped molecule (e.g. acetic acid for –COOH) is fetched so you get a real conformer.

CAS numbers are resolved through PubChem's CAS registry cross-reference, so 50-78-2 lands on aspirin, not on something that merely mentions it.
Materials without a single molecular record (graphene, steel, most polymers) have no structure to fetch — draw those in ChemDraw and open the .cdxml here.

3D model
The folded model is a deterministic coarse-grained geometry driven by backbone constraints and the predicted/selected base-pair pattern. It is not an experimentally determined or atomistic 3D structure.

Paste a sequence, then build publication-ready linear, duplex or folded 2D schematics; inspect oligo properties and complementarity; or generate a secondary-structure-driven coarse-grained 3D model.
