Fold Commons — apps & tools https://foldcommons.org/apps.xml Enumerated catalog of the free, in-browser Fold Commons apps and tools, with per-tool age bands. A partner site can render registry cards, cross-site search records, and child-safe age-gated links from this feed at build time. FoldLens https://foldcommons.org/viewer iPad-first AlphaFold Database browser with honest pLDDT confidence display and on-device Apple Intelligence residue explanations. The lens through which everything else flows. FoldLens Junior https://foldcommons.org/junior/explore The K-12 (ages 9–14) sibling of FoldLens: the same AlphaFold Database content in a tier-appropriate voice, NGSS-aligned, COPPA-safe by design. Pick a protein and see its real 3D shape in the browser. ResearchAtlas https://foldcommons.org/tools/researchatlas A reader over the Fold Commons research archive — search and read deep reports on AlphaFold and AI for biology, entirely in your browser. The native app adds on-device Apple-Intelligence grounded summaries. FoldCompare https://foldcommons.org/tools/foldcompare AlphaFold vs Experiment: superpose an experimental structure (PDB) and AlphaFold’s prediction (AFDB) client-side for an honest RMSD diff and per-residue divergence profile. PocketScout https://foldcommons.org/tools/pocketscout A binding-pocket finder: enter a UniProt accession or PDB id and it finds candidate cavities in your browser, ranked by a transparent geometric heuristic. Geometry, not a druggability predictor. AntibodyAtlas https://foldcommons.org/tools/antibodyatlas Find the epitope/paratope interface of an antibody–antigen complex from geometry, clustering the paratope into CDR-like contact loops. A geometric contact map, not an experimentally-mapped epitope. PhenoFold https://foldcommons.org/tools/phenofold A phenotype → causal-gene → protein-structure explorer over well-established monogenic conditions, with a live AFDB render and key-residue highlight. Not a predictor or diagnostic. NobelTimeline https://foldcommons.org/tools/nobeltimeline The structural-biology Nobel Prizes as an interactive timeline, with verbatim citations, primary-paper DOIs, and 3D deep-links into the viewer. CASPTracker https://foldcommons.org/tools/casptracker An honest scoreboard of every CASP experiment (1994→2024) built from real published results — no invented GDT_TS, era filters, and a same-origin trajectory chart. ClinicalAtlas https://foldcommons.org/tools/clinicalatlas A sourced tracker of AI-in-clinical-trials milestones, every entry cited, with a strict no-causation posture and honest coverage gauge. SovereignBio https://foldcommons.org/tools/sovereignbio Public AI-biotech capital flows (IPOs, partnerships, funding, M&A) — every figure cited to a primary source, with an honest coverage gauge and an annual-totals chart. MoleculeFlow https://foldcommons.org/tools/moleculeflow Landmark closed-loop / self-driving-lab discovery runs, each a five-stage loop cited to its primary paper by DOI, with a hand-drawn closed-loop diagram. CellTour https://foldcommons.org/tools/celltour Guided, textbook-sourced tours of eight cell types with ordered stops, honest coverage, and step-through — a function-first reader for how cells are built. ProteinQuest https://foldcommons.org/tools/proteinquest A COPPA-safe amino-acid sorting game — sort each of the 20 standard amino acids into its property class. No accounts, no outbound links, nothing collected. VerbSnap https://foldcommons.org/tools/verbsnap A COPPA-safe science-writing game — call each protein claim mechanism or purpose under a shrinking timer, and rewrite teleology as honest physics. PoreSort https://foldcommons.org/tools/poresort Predict what gets through each real membrane channel (aquaporin-1, GLUT4, CFTR) before the reveal — scored on your prediction, not luck, with a live AlphaFold render. RatchetRun https://foldcommons.org/tools/ratchetrun Set the ATP level and predict a molecular motor’s drift — a biased-random-walk game about why motors ratchet through jitter rather than stride. HingeHunt https://foldcommons.org/tools/hingehunt Judge a crisp AlphaFold model’s domain arrangement, then reveal the PAE — your call scored live from the fetched predicted-aligned-error matrix. DisorderDuty https://foldcommons.org/tools/disorderduty Tag a protein’s low-confidence stretches Broken or Working — the reveal proves Working from live UniProt functional annotations. OneLetterLottery https://foldcommons.org/tools/oneletterlottery Draw a real one-letter variant and call its impact before the reveal — a calibration game about why most mutations are quiet and a few are not. TwoIslands https://foldcommons.org/tools/twoislands Paint a Firm-or-Fuzzy prior on two crisp domains, then reveal the real PAE — a gentle confidence game (ages 9–14), scored live from AlphaFold. WhatsMissing https://foldcommons.org/tools/whatsmissing Pick what a single-chain AlphaFold model leaves out — proven live from UniProt cofactor and subunit annotations. FlexiFit https://foldcommons.org/tools/flexifit Predict whether a pocket is a rigid keyhole or reshapes on contact — an induced-fit game with live enzyme renders (ages 9–14). GripChain https://foldcommons.org/tools/gripchain Set the coupling between hemoglobin’s four subunits and match the real oxygen curve — a game about why an allosteric signal spreads through contact, not instantly (ages 15–18). HearTheChain https://foldcommons.org/tools/hearthechain An accessibility-first listening game: AlphaFold confidence sonified along the chain as pitch. Match the sound to the protein and learn that low confidence is not the same as unimportant (ages 9–14). VanishPoint https://foldcommons.org/tools/vanishpoint Drag AlphaFold’s confidence lens and predict where each region vanishes — a game that shows a faded region is usually flexible and functional, not a mistake (ages 9–14). DomainCuts https://foldcommons.org/tools/domaincuts Carve a protein into its folded domains, then use AlphaFold’s PAE to judge how much to trust the way the domains sit relative to each other (ages 15–18). TolerancePaint https://foldcommons.org/tools/tolerancepaint Paint which parts of a protein tolerate change, then reveal the real AlphaMissense heatmap — most changes are harmless, the damaging ones cluster at a few critical spots (ages 15–18). BuriedBet https://foldcommons.org/tools/buriedbet See one subunit, bet which parts get buried against its partner, then load the real assembly and score your guess against the true interface — many proteins don’t work alone (ages 9–14). PencilOrInk https://foldcommons.org/tools/pencilorink You are the renderer: choose which parts of a protein to draw in firm ink and which to draw sketchy. Sketchy is how you honestly draw a flexible, functional region (ages 9–14). SpliceSplit https://foldcommons.org/tools/splicesplit Compare two spliced isoforms of one gene and pick the exon that explains the difference — splicing makes different chains, not one chain morphing into several shapes (ages 15–18). NotMarbles https://foldcommons.org/tools/notmarbles A space-filling model looks like a solid pile of marbles, but atoms jiggle — bet which regions hold still and which smear, then watch the mobile ones jitter (ages 9–14). The protein-structure pathway https://foldcommons.org/learn/pathway A suggested learning ladder: nineteen rungs from “a cell has parts” to “why prediction is trustworthy”, with two age-band entry points. Each rung links to a free tool, and the prerequisite arrows show what tends to make the next step easier. NumberReader https://foldcommons.org/tools/numberreader Read the real AlphaFold confidence numbers off human haemoglobin: guess how sure the model is for a region, then see its actual per-residue pLDDT and pairwise PAE — computed live from the model — and say it plainly: a prediction, not an experiment (ages 15–18).
