A clearer workflow.
With scientific judgment.

These terms describe access to the current MolSage research website and available modules.
Research use and review
MolSage supports molecular drawing, route exploration, spectral interpretation, mass analysis and experiment planning. Generated routes, assignments and optimization suggestions may be hypotheses. They do not establish structural proof or replace experimental confirmation and qualified scientific review.
Your account
Registration and sign-in are required to access every module. Provide accurate account information and keep your password private. Accounts are intended for individual users. Authorized owners can suspend misuse, revoke sign-in sessions and help recover an account through a temporary one-time link.
Free advanced processing
Each new account receives five free advanced AI processing uses, shared across all supported modules. A completed advanced request uses one allowance. A Chemstrom route-planning request includes its associated route reviews; a separate image-recognition request uses a separate allowance. Signing out, changing devices or opening another module does not reset the total.
Free standard access
Each new account also receives ten free standard workspace opens for NMR, Draw and Optimization. Opening a module or opening it in a new tab uses one standard access. Switching back to a module already open in the same workspace tab does not use another. The standard allowance is shared across your account.
Monthly membership
The introductory price is ₹500 per user for the first month. From the second month, the price is ₹1,500 per user per month. Continued use after the relevant free allowance requires an active membership. Online subscription payments are coming later. No charge or automatic subscription is created by registration or by viewing the membership page.
Manually confirmed access
An owner may record an active membership with an expiry date following a separate confirmation. This administrative action grants access; it does not itself collect money or create an automatic renewal. Allowance adjustments and membership changes are recorded with a reason.
Module availability and desktop editions
Modules may be updated or temporarily paused independently. Their current feature status is shown on the website. Optimization currently provides a read-only synthetic campaign preview. Future features are not included until released. Windows and macOS desktop editions, purchase options and availability are separate from web membership.
Scientific information
Only submit inputs you are authorized to process. Advanced processing sends relevant inputs to hosted analysis services. Review the Privacy notice and your organization’s requirements before uploading confidential work.
