About

FoldVision

Features
Read full description

FoldVision turns the world's protein structures into something you can hold, turn, and understand. Search more than 200,000 experimentally determined structures from the Protein Data Bank, load AlphaFold and ESMFold predictions, or build a DNA or RNA helix from a typed sequence. Everything renders in interactive 3D — rotate it with a finger, zoom into an active site, and switch between ribbon, surface, ball-and-stick and space-filling views. EXPLAIN ANY PROTEIN Tap Explain and the app writes a plain-language account of what the protein does, grounded in curated UniProt data and generated privately on your device with Apple Intelligence. A guided tour walks you through the key regions, lighting up each one on the structure as it's described. Available in 11 languages. COMPARE TWO STRUCTURES Load two structures and see exactly what changed. Structural-change coloring shades every residue from blue (superposes) to red (diverges). Sequence-change coloring separates conserved residues from substitutions. Watch a smooth morph between two conformations, or set them side by side. EXPLORE THE DETAIL • Annotations — domains, active and binding sites, modifications, variants and mutagenesis, drawn from UniProt. Tap any one to spotlight it on the structure. • Sequence view — the full amino-acid sequence with secondary structure, hydrophobicity, charge and B-factor tracks. Tap a residue to find it in 3D. • Color by secondary structure, chain, hydrophobicity, charge, domain or confidence (pLDDT), with color-blind-safe palettes throughout. • Measure distances, pin points of interest, and see the ligands and ions bound in the structure. NUCLEIC ACIDS Fold an RNA sequence into its predicted secondary structure with ViennaRNA, or build an idealized DNA or RNA double helix from any sequence. SHARE YOUR WORK Export a still image, a spinning video, or a 3D USDZ model you can drop into a presentation or an AR scene. BUILT FOR EVERY DEVICE Designed for iPhone, iPad and Apple Vision Pro, with layouts tuned to each. Structure and annotation data come from the RCSB Protein Data Bank, UniProt, AlphaFold DB, ESM Atlas, InterPro and Reactome. Full credits are in the app.

Internalize turns dense papers into immersive, narrated explainers. Pick a paper and watch it come alive: a particle renderer highlights exactly what is being discussed while a clear voice walks you through the ideas, at the depth you choose. THREE DEPTHS - EXPERT: full technical detail - COLLEGE: clear, with everyday analogies - ELI5: explain it like you're five YOUR OWN PAPERS Sign in with Apple and import any PDF up to 60 MB. Internalize builds your explainer automatically (narration, highlights, diagrams), shows live progress while it works, and notifies you the moment it is ready. Your imports are private to your account, and you can delete your account and all data at any time, right in the app. MADE FOR FOCUS - Word-by-word text that follows the narration - Readout speed control, 0.8x to 1.5x - Jump to any page, figure, or equation - Diagram mode, dark mode, zoom-follow mode - Works on iPhone, iPad, and Mac

Verdict

The call

The clearest difference is in-app purchases: FoldVision at none against Internalize's 3. FoldVision also leads on update cadence (daily vs every 4 days). Internalize's advantage is iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
