Signing in an AI assistant (ChatGPT, Claude, Cursor) to Athanor: if you were signed out, the permission screen now appears as soon as you sign in, without opening the link again.
Athanor 0.3.48
Sticky notes are prose: C2, H2O and other text stay as typed. Turn on Chemistry in the text bar while writing on a note to format formulas there.
Everywhere else, a single element symbol with a number (C2, N1) is read as a position and left alone; formulas, charges and H2, N2, O2 still format.
In a shared document, a new sticky note shows who wrote it and when, small at its foot.
Athanor 0.3.47
Sticky notes are a tool on the pen row (N): click to drop a note and type, pick from nine paper colors, Enter for a new line, Esc to stop writing. Long notes wrap and their writing shrinks to fit.
Select a note to swap its color from the bar above it. Alt-drag a note to copy it.
Whiteboard is gone from Home: a board is a normal drawing, and drawings made as whiteboards open as they always did.
Fix: a copied group (Duplicate, Alt-drag, paste) keeps its name.
Practice no longer shows points: Check says what is right, with no score.
Athanor 0.3.46
Fix: in practice with every structure drawn, correct curved arrows are marked right again, in every mechanism.
Athanor 0.3.45
Fix: in practice, undo no longer brings back the answer. Undo stops at the problem as it was dealt, and only Show answer turns the key face up.
Arrows-only practice questions ask only for the arrows, without the old instruction to draw the products.
Athanor 0.3.44
Opening a protein by its id (1CRN in Quick insert, or Open a protein structure) now loads it in the 3D preview.
Audio recordings show as chips at the top right of the canvas as soon as you press Stop.
Athanor 0.3.43
Practice is now a switch in the problem set builder: pick templates, turn on Practice for myself, and problems come one at a time with hints, answers locked until you ask, and no points. Practice arrow-pushing on Home opens it with the mechanisms chosen.
Mechanism practice draws every structure for you: add the curved arrows, and Check names the step that is wrong. Turn on Also draw the products to draw them yourself. Choosing another mechanism changes the problem right away.
Open a Word document and it comes in as text you can edit, with every ChemDraw drawing in it as a structure you can edit, its pictures and its tables, in one group.
The isotope pattern of a labeled compound counts each labeled atom as its isotope: ¹³CH₃COOH and CDCl₃ now show the right peaks.
The release notes open from Settings, About in the desktop app too.
Athanor 0.3.42
Isotopes: type D, T or 13C on an atom, or set the mass number in Properties. The label shows it (D, ¹³C), and the formula, both masses, SMILES and MOL files carry it.
A simpler timeline toolbar: play, start and loop are one control, Steps and Keyframes are tabs over the track, and Copy and Delete appear when you pick a step. Present, the energy diagram and new animations are in More.
Practice arrow-pushing opens with the curved-arrow tool, the starting materials large in the middle of the card, and only your solved count and streak beside it.
The Perspective tool turns a structure back to a readable angle if you let go of it edge-on.
Audio recordings show as chips at the top of the page: play, rename or delete them there.
Type a PDB id such as 1CRN into Quick insert to open the protein in the 3D viewer, or use Open a protein structure.
Fixes: lone-pair dots in slide-sized drawings no longer run together, an anion’s charge stays clear of its lone pairs, and release notes no longer appear in your first sessions.
Athanor 0.3.41
Practice arrow-pushing: mechanism problems one at a time, from SN2 to E1 with a hydride shift or at random. Draw the curved arrows and check them, ask for hints, and keep a streak. The answer stays hidden until you ask for it. From Home, or a new problem set.
The Perspective tool, in the Select menu: drag a structure to turn it in space. Shift keeps to one axis, Ctrl turns in 15-degree steps, Alt turns it in the page, and a double-click puts it back. Every stereocenter keeps its R or S at any angle.
Athanor 0.3.40
Open a PowerPoint deck, a PDF or a Word file with Open, from Home, or by dropping it anywhere on the window: it opens in a new tab as slides or pages you can edit. Dropped on the canvas, it goes beside what is there.
A cleaner timeline toolbar: Basic and Advanced as one switch, Animate my arrows as the main button, Save as video with GIF and other formats beside it, and the example mechanisms in a More menu. On a narrow window, the least-used controls move into More instead of crowding the row.
NMR tables name OH, NH and SH protons by their own atom (OH, NH₂, CO₂H, phenol OH) instead of calling them CH, and shift labels keep clear of warning marks.
PDB files include every hydrogen, like XYZ and MOL2.
Buyable starting materials in a route say when an item is made on demand and its price may change.
Athanor 0.3.39
Export slides to PowerPoint: text, shapes, arrows, pictures and tables stay editable, structures come along as pictures that open as chemistry again in Athanor, and speaker notes are kept.
Slides have speaker notes, and a slide show has a presenter view with this slide, the next one, your notes and a timer.
Each imported PowerPoint, Word or PDF file is one group named for the file, placed beside what is already on the page.
Imported PowerPoint decks keep their layouts: titles where the master puts them, two-column slides side by side, and subscripts and charges such as H₂O and Fe³⁺.
Automatic atom mapping gets acyl substitutions right: in an esterification the ester keeps the alcohol's oxygen.
Predicted shifts on a structure stay next to their own atoms, with a short line where space is tight, as one layer.
The converter writes PDB, Gaussian and ORCA inputs, RXN and RDF, and reads reaction SMILES.
In 3D: an estimated dipole arrow, and five materials (Gloss, Clay, Toon, Neon, Print).
Fixes: SO42- formats as SO₄²⁻, sticky notes grow to fit, formula captions are one per structure, compressed chains draw straight, Settings shows the right yearly prices, and the Labeler uses common names.
Athanor 0.3.38
Drop a PowerPoint file on the canvas to edit it: every slide becomes a slide in Athanor, with its text, shapes, pictures and tables. Anything that cannot be edited, such as a chart, is marked where it was.
When an organization keeps Athanor off the network, the top bar says so.
Athanor 0.3.37
Sites that embed Athanor can build DNA, RNA and peptides from their letters, open HELM, and transcribe, translate or replicate a sequence.
Athanor 0.3.36
Protected-group labels such as NHBoc, NHCbz, NHFmoc, OTBS, OBn, CO2Et and CO2tBu now count in the formula and expand to full structures.
Structure to name shows the name, with Insert as text to put it under the structure.
Exports are more faithful: no stereocenter is lost, CDX keeps radicals and metallocenes, CML keeps open double bonds open, and 3D files no longer place atoms on top of each other.
Predicted shifts on the structure sit beside their atoms, clear of the bonds.
In 3D, press T for atom labels and R/S and E/Z.
Athanor 0.3.35
Compare a predicted NMR spectrum with a measured one on the page: the measured trace is drawn under the prediction, each signal is paired with its predicted shift, and Assign links them to their atoms.
Point at an atom in the structure to light its row in the NMR window.
Problem sets can hide predicted NMR from students, problem by problem.
Athanor tells you before a trial or plan ends, and if a payment does not go through. Nothing is ever deleted when a plan ends.
Suite Plus and Ultra now use Claude Fable 5.2.
Athanor 0.3.34
Predicted NMR spectra: open 1H or 13C from a structure to see the spectrum with first-order multiplets, drag across it to zoom on a multiplet, and copy the journal line, CSV or JCAMP-DX.
Three new official plugins: a solution and buffer calculator, a formula finder from HRMS m/z, and a CHEM21 solvent selector.
Plugin windows now fit their content and use Athanor dropdowns and fields, and formulas show proper subscripts.
A ChemDraw-style shortcut set is available in Settings for anyone coming from ChemDraw.
Athanor 0.3.33
PDB export and the structure checks are now part of Athanor itself: export PDB from Export, see unusual charges and stray atoms in the issues badge, and run Choose undefined stereocenters from Ctrl+K.
Plugins open in a floating window you can drag anywhere, and Dock it puts one in a side panel. Plugin panels now appear in the Panels menu too.
Official plugins have proper app icons, and plugin galleries show the plugin up close.
Athanor 0.3.32
Plugins now have a home in the top bar: run, open and manage every plugin you have on from one menu, beside Animate.
Each installed plugin has a Try it button and a line saying exactly where it appears, and installing one tells you where to find it.
Plugin listings have screenshot galleries, and developers can upload their own icon and up to eight screenshots when they publish.
Athanor 0.3.31
Build mechanism now uses our own chemistry: a textbook rule when the reaction is a known class, and our own mechanism model for the rest, laid out one step per row with every species named. It says plainly when an answer stops short of your product.
Plugins: browse, install and manage plugins in the new Plugins window (Ctrl+K, Plugins). Every published plugin is screened, reviewed and signed by Athanor, and asks before it reads or edits your work.
Make your own flashcard decks from a document or a Quizlet or CSV file, publish them, and add decks other people shared.
Single-electron (fishhook) arrows: Animate my arrows reads them in pairs, so a bond breaks evenly or two radicals join.
Athy now shows Quick insert, hold to select, catalytic cycles and sharing in the tour.
Fixed: a long curved arrow can be clicked anywhere along its curve; plugin panels no longer report an error while starting; the periodic table plugin inserts neutral elements.
Athanor 0.3.30
Quick insert: press / anywhere on the canvas and type a name, SMILES, CAS number or formula (typos too), or paste or drop a picture, and it is drawn where your pointer is.
Hold still in any drawing tool and the ring fills: pick things up and move them without switching tools. Clean up, flip, rotate, align and distribute now glide into place.
Catalytic cycles: make one from your reactions, drop structures onto it, reverse a step, and name each step.
Flashcards are now a study view of their own, with reaction and name-to-structure decks, a real flip, and New, Learning and Due counts.
A new export picker, with what each format keeps and loses. Exports leave out pages chrome and keep translucency.
Convert to bond-line now redraws a Newman, Fischer, Haworth or chair as an ordinary skeletal drawing, keeping every R and S.
Fixed: radicals are kept in MOL files, trigonal centers are drawn at 120 degrees, and more compounds are named.
Athanor 0.3.29
Orbital energies in eV and a predicted IR spectrum, calculated on the arbastro server: Compound info, Orbitals and IR. The accurate level also estimates the ionization energy.
Routes are named by the steps the service can name ("Amide coupling, N-alkylation and 6 more steps"), and arrows no longer say conditions were not predicted.
Fixed: exports leave out AI proposals you have not approved yet; video export records the drawing; polls and the phone remote say when the live connection fails.
Fixed: documents keep syncing while a live session is open, a server that never answers gives up after a minute, and the huddle bar stays in 3D.
The picture reader is now called Cernere.
Athanor 0.3.28
Assign a comment to someone, and get an email when you are assigned or @mentioned. Home, Shared with me starts with For you: the comments waiting on you.
Share links can have an end date and a password.
Team libraries: your organization can keep molecules for its members, and you are told when one is updated.
Route search: start from up to 200 compounds you have, ask for routes that pass through or leave out compounds, pick the bond to start at, and prefer full syntheses. Each route says why it is ranked where it is, and steps are named.
Automatic versions are also kept on your account: one every half hour, the newest 20 per document.
Fixed: voice mode no longer hears its own voice as yours, and product prediction keeps diastereomers apart.
Athanor 0.3.27
Fixed: live editing in the desktop app now connects, so you see each other's cursors and edits, and a document's name stays the same for everyone in it.
Fixed: opening a document from Shared with me shows it, with its name, instead of a blank Untitled tab; Copy link in the desktop app gives a web link anyone can open.
You get an email when someone shares a document with you.
Visualize orbitals: select a structure and every atom gets its hybrid, p and s orbitals.
Build mechanism appears when you select a whole reaction, not only its arrow.
The route box names each route by its disconnections, shows its score and draws what it starts from.
Fixed: Paste SMILES adds the structure instead of replacing the drawing, and numbered reagents such as "1) NaBH4" now reach product prediction.
Athanor 0.3.26
Athanor in Spanish: every screen, menu, notice, problem template and the assistant's replies follow Settings, Language.
Comment on a region of the page: drag out a place, and the thread shows its outline and pin.
Attach pictures, PDFs and chemistry files to comments and replies, by the paperclip, a paste or a drop; pictures open larger.
Fixed: voice mode now answers when you stop talking, says when it heard you but caught no words, and says why when it cannot listen.
Your rating now sits beside the average on a community upload, and a report you sent shows as Reported.
Fixed: the assistant writes reagents on an arrow you already drew instead of redrawing the route.
Numbers everywhere in the app follow your language's format.
Athanor 0.3.25
Fixed: a route search no longer starts again on a finished route, and product prediction no longer reruns on a drawn product, when a structure sits tight against the arrow.
Fixed: a structure drawn in another charge state is named (ATP for ATP4-), every formula shows its charge, and export no longer cuts off a charge drawn on the left.
Haworth projections keep their labels apart and a large group like adenine off the ring; publishing a structure keeps it exactly as drawn.
Metallocenes come in as sandwiches with eta-5 bonds, and the formula of dimethyltitanocene is corrected to C12H16Ti.
When the route search cannot be reached, the box says so and you choose whether to ask the AI assistant instead.
Predictions list possible side products (starting material, isomers, over-reaction), each one click to add.
Where substitution goes now covers pyrrole, furan, thiophene, indole, benzofuran and pyridine, with one substituent on the ring.
ChemDraw brackets, boxes and ellipses in and out; CDX, JPEG and WMF export; a Whiteboard on Home with Shift+S for a sticky note; Home in Spanish.
Athanor 0.3.24
Fixed: a document's "viewers cannot copy or export" setting and its handwriting readings now survive a save.
