Spectra, impurities and stability data evaluated,ready for sign-off.

For analytical, QC and CMC teams in pharma, CDMOs, contract labs and specialty chemicals. You receive the finished report with its reasoning, your expert signs it off. Our methods are independently measured: on the MolecularIQ chemistry benchmark without CovaSyn 14 to 41 % correct, with CovaSyn 76 to 92 %.

Typical lab problems

Which problem is on your bench right now?

You describe the problem, we run the evaluation and deliver the report your expert signs off.

All lab problems at a glance

How we work

From an open problem to a result your expert signs off.

You do not have to choose, install or learn anything beforehand. Whether and how we can help, we clarify together on your case.

  • 1. Describe the problem

    In the initial call, 30 minutes on Microsoft Teams. We tell you honestly whether we can solve it.

  • 2. Send the data

    If you wish, we sign a non-disclosure agreement first, then you send the data. We run the evaluation, typically within 5 working days once we have your complete data.

  • 3. Sign off the result

    You receive the report with reasoning and input data. Your expert reviews and approves it.

Measured on an independent benchmark

How often structure questions about molecules are answered exactly right.

Tasks on the molecular graph such as atoms, rings, scaffolds and stereocentres, not the interpretation of spectra or stability data.

Evidence and science

Measured independently, open to checking.

Every answer either matches the stored solution exactly or counts as wrong. Dataset and evaluation are public.

FAQ

Frequently asked questions

What is CovaSyn?

CovaSyn solves what otherwise piles up in analytical, QC and CMC labs: spectra without an assignment, unknown impurities, stability data without a shelf-life statement, open ICH M7 questions. You get a sound result, your expert signs it off.

How does working together start?

You describe your problem in the initial call, 30 minutes on Microsoft Teams. We tell you honestly whether we can solve it and in which form it helps your lab most. You do not have to choose, install or learn anything beforehand.

Can I see upfront what I get?

Yes. Under “Example evaluations” we show typical lab questions on publicly known compounds, every number computed and checked. You pick the slot for the initial call right after a short form.

Where is our data kept?

Hosted at Hetzner in Nuremberg, data kept in the EU. No training on your data. Deletion on request within 30 days, backups included.

How reliable are the results?

14 to 41% without CovaSyn, 76 to 92% with CovaSyn. Measured on MolecularIQ, an independent benchmark we did not design (ICLR 2026, arXiv:2601.15279, Klambauer Lab, JKU Linz). Every result comes as a reasoned report that your expert reviews and releases.

Next step

Not sure where you stand?

Then we clarify it in 30 minutes on Microsoft Teams, using your concrete case. Afterwards you know whether and how we can solve your problem, or that we cannot. If you would rather see a result first, our example evaluations show typical lab questions on publicly known compounds, every number computed and checked.
