Log failed reactions.
Search what did not work.
NullYield is an AI-assisted repository for unsuccessful chemistry reactions, negative results, and low-yield experiments.
NullYield is currently in closed beta while the database, moderation, and safety controls are tested.
AI extraction
Paste messy lab notes and convert them into structured reaction records.
Failed reaction search
Search by reaction class, reactants, solvent, outcome, evidence, or notes.
Chemistry-native records
Store names, SMILES, conditions, outcomes, evidence, and molecule structures.
Support the beta
NullYield is currently in beta.
The project is being built as an independent chemistry tool to make failed reactions easier to record, search, and learn from. Keeping it online requires ongoing costs such as hosting, database storage, domain maintenance, security tools, and AI-assisted extraction.
If you find the idea useful and want to help keep NullYield running while it grows, you can support the project on Patreon.
Support is completely optional and does not change the Terms of Use, data policy, or ownership/licensing rules for submitted reaction records.
