Scientific computing,
without detours.
Mathery brings together a notebook, computer algebra, plots, a spreadsheet, and optional AI in a local workspace. Lite launches for free in the browser, with no account and no telemetry. Pro is being prepared for desktop.

Capabilities
One document, from the first calculation to exploration.
Every feature below is illustrated by the real application, in its current development state.
01
Notebook & computer algebra
One expression per line, persistent variables, and results recalculated in the same document. Simplification, differentiation, solving, and step-by-step work complement numeric computation. Supported steps are re-evaluated to catch an inconsistency — without claiming to replace a human proof.
02
2D & 3D plots
Curves, scatter plots, parametric traces, and surfaces stay bound to the expressions that produce them. Data does not leave the notebook to be visualized.
03
Spreadsheet & RPN
The spreadsheet prepares series and makes cells or ranges available from the notebook. The RPN panel offers a stack for sequential calculation. Both tools remain optional and open only when they are useful.
04
AI on your terms: BYOK or local
Mathery sells neither an AI quota nor a hidden subscription. You can supply the key of a cloud service you choose, or use Ollama or WebLLM locally when the model, memory, and machine configuration allow it. A cloud AI receives only the requests you decide to send.
05
Exam mode for practice
A deliberately constrained environment helps you repeat exercises with fewer distractions. It is a practice mode: Mathery Pro is not an approved calculator for an official exam, and acceptance always depends on the exam regulations.
06
Local privacy by default
Notebooks and calculations stay on your device by default, with no product telemetry. A network connection is used only for an explicitly online feature — for example a cloud AI provider, exchange rates, or a self-hosted collaboration relay.

Frequently asked questions
What to know before launch.
01Is Mathery Pro already available for purchase?
No. Pro is not on sale and no launch date has been announced. The announced public price is €24 as a one-time purchase. Mathery Lite is already free to use in the browser.
02What is the difference between Mathery Lite and Mathery Pro?
Lite offers standard, scientific, HiPER, and graphing modes for free in the browser. Pro adds the full desktop workspace: multi-line notebook, computer algebra, linked plots, spreadsheet, RPN, .calc files, and optional AI.
03What does “€24 lifetime” mean?
The announced price is a personal, perpetual licence for the 1.x major version, including patch and minor updates. A future major version may be sold separately.
04Does AI actually run locally?
Yes, via Ollama or WebLLM depending on the installed model and the machine's capabilities. Cloud providers remain available as BYOK: you then use your own key and your own quota.
05Is exam mode approved for the French baccalauréat?
No. It is only for practising in a stricter environment. For an official exam, you must follow the applicable rules and use authorised equipment.
