Understand the task
Identify the target and your goal. Ask for clarification when needed.
Do the chemistry
Use chemistry tools for structures, calculations or sources.
Check the result
Apply relevant checks to generated structures, reaction balance and references.
Show it clearly
Present structures, charts or routes; label predictions and missing information.
Checks do not guarantee experimental accuracy. Predictions are distinguished from measurements.
How do the checks work?every tool. one workspace.
Structures, literature, predictions and reports. The right tools for your question, in one conversation.
NMR predictor
Model-predicted ¹H and ¹³C chemical shifts. Predictions are not measured spectra.
IUPAC ↔ SMILES
Translate any structure between systematic name and machine code.
Paper search
Search 200M+ papers with structure-aware semantic queries.
Safety reports
GHS-style hazard drafts generated from any SMILES.

one question, two views
Do more than read a molecule. See it. Explore it. Work with it.
An explanation can help. Cheemly also turns structures and data into usable views in the same conversation.
Explanation view
Aspirin is acetylsalicylic acid and contains an ester group. The example concentrations at 0, 5 and 10 minutes are 1, 0.6 and 0.3 M respectively. Plot these against time to see the change. Check question: Which functional groups does aspirin contain?
cheemly
Same conversation, useful outputs.
Inspect the structure, switch views, read the graph and answer the question.
Molecule · 2D / 3D
From question to result
What could a working day feel like?
Learn through structures
Draw a molecule, explore its functional groups and ask why it behaves that way in the same chat.
Keep research together
Find literature, turn data into a chart and preserve your research context.
Explore synthesis routes
Explore retrosynthesis routes and starting materials; compare the reasons behind each option.
Check your understanding
Strengthen your understanding with quick questions, flashcards and explanations.
Return with context
Return to structures and sources in your saved conversation to develop your report.
Read your data visually
Compare concentration, time or energy data in interactive charts.

before you ask. we already answered.
Six honest answers to the questions chemists send first.
Yes. Prompts and structures are encrypted at rest, never used to train shared models, and exportable on demand. Delete everything from one screen, any time.
Generated structures, reaction balance and references undergo relevant chemistry checks. Failed checks lead to correction or a clearly stated limitation.
Anytime. Free stays free. Paid tiers cancel mid-cycle with no penalty. Your workflows and notebook stay accessible on Free after downgrade.
Cheemly combines chemistry drawing, calculations, sources and reports in one conversation. Model predictions are not presented as measurements.
Yes — JSON, CDXML, MOL, SDF, PDF, or a one-click ZIP. Your data, your hard drive. Even on Free.
The meter shows your remaining allowance as a percentage. Task scope, answer quality and tools can affect consumption. Your account shows the renewal time.
