EduArc includes tools for searching molecules and rendering chemical structures. Add professional molecular diagrams to your courses, study guides, and assignments.
Chemistry tools search PubChem, one of the world’s largest free chemistry databases with millions of compounds.
What You Can Do
Search Molecules Find molecules by name, formula, or SMILES
Render Structures Generate 2D molecular diagrams as SVG
Add to Content Embed diagrams in websites and PDFs
Searching for Molecules The AI can search for molecules in three ways:
By Name
By Formula
By SMILES
Search for caffeine. Find the molecule aspirin. Look up glucose.
Search for the molecule C8H10N4O2. Find molecules with formula C6H12O6.
Search for the molecule with SMILES CCO. Find the structure CN1C=NC2=C1C(=O)N(C(=O)N2C)C.
SMILES is a text notation that represents molecular structure. You can copy SMILES from other chemistry resources.
What You’ll Get When the AI finds a molecule, it returns:
CID - PubChem Compound ID (unique identifier)Name - Common name of the moleculeFormula - Chemical formula (e.g., C8H10N4O2)Molecular Weight - Mass in g/molSMILES - Structure notation (needed for rendering)
Rendering Structures Once you’ve found a molecule (or if you already know its SMILES), the AI can render it as a 2D diagram.
Basic Rendering Add the molecular structure of caffeine. Render the benzene molecule. Add a diagram of ethanol.
The AI will:
Search for the molecule to get its SMILES
Render a 2D diagram (default 300x300 pixels)
Save it and embed it in your content
Custom Size You can request specific dimensions between 100-1000 pixels:
Render aspirin at 400x400 pixels. Add a large diagram of glucose (600x600). Show caffeine structure at 200x200 for inline use.
Size recommendations:
200x200 - Inline with text300x300 - Standard display (default)400x400 - Teaching focus600x600 - Full detail view For Websites
For PDFs (Typst)
Diagrams are rendered as SVG (vector graphics):
Scales to any size without losing quality
Loads quickly
Works on all devices
Saved to /public/molecules/ in your project
The AI will provide embed code like: < img src = "/molecules/caffeine.svg" alt = "caffeine" width = "300" height = "300" />
Diagrams are optimized for print with publication-quality styling:
High resolution SVG
Saved to assets/molecules/ for Typst compilation
Clean lines suitable for printing
The AI will provide Typst code like: #figure ( image ( "assets/molecules/caffeine.svg" , width : 300pt ), caption : [Caffeine molecule] )
Common Use Cases Organic Chemistry Add structures of all functional groups. Show the reaction mechanism with molecular diagrams. Add before and after structures for the esterification reaction.
Biochemistry Add the structures of all 20 amino acids. Show the glucose and fructose molecules side by side. Add the structure of DNA bases.
Pharmacology Add the structure of paracetamol. Show the molecular structure of ibuprofen. Compare the structures of similar drugs.
General Chemistry Add the structure of a water molecule. Show examples of ionic and covalent structures. Add diagrams for the hydrocarbons series.
Example Prompts Adding Single Structures Add the molecular structure of caffeine. Show the benzene ring structure. Add a diagram of the ethanol molecule.
Comparing Structures Show the structures of methanol and ethanol side by side. Add a comparison of glucose and fructose. Display the isomers of butane.
In Context In the section about alcohols, add the structures of the first three alcohols. Add molecular diagrams wherever compounds are mentioned. Include structures in the organic chemistry flashcards.
For Assessments Add a blank space where students should draw the structure. Show the reactants but not the products. Add the structure with one part missing for students to complete.
Tips for Chemistry Content
Be Specific Use the full molecule name or formula to avoid confusion between similar compounds
Consider Context Think about whether students need to see the structure or draw it themselves
Size Appropriately Use 400-600px for teaching, 200-300px for inline reference
Search First Search by name to get the correct SMILES before rendering
How It Works Behind the scenes, the chemistry tools use:
PubChem - NCBI’s open chemistry database with millions of compoundsRDKit - Industry-standard cheminformatics library for renderingSMILES notation - A text string that encodes molecular structure
Search
The AI searches PubChem for your molecule by name, formula, or SMILES
Get SMILES
PubChem returns the canonical SMILES notation for the structure
Render
RDKit generates a 2D SVG diagram from the SMILES
Embed
The diagram is saved and embedded in your content
Limitations The chemistry tools work with molecules in the PubChem database. Very unusual, proprietary, or newly discovered molecules may not be available.
If a molecule isn’t found:
Try an alternative name (common vs IUPAC)
Use the chemical formula instead
Check the spelling
Try searching by SMILES if you have it from another source
