The isotopist's workspace, built for research and teaching. A structured database for your samples, CRMs and standards, a spreadsheet wired to that database with its geochemical formulas, the mapping of your sites, figures ready for publication and durable archiving in the open ISOF format. No subscription, no limits, no compromise on your data.
Free, for life. Not a trial, not a stripped-down version.
Isotope results too often end up scattered across spreadsheets, notebooks and figure folders. The CRMs and calibration standards are recorded nowhere reusable, graphs are rebuilt by hand for every paper, and nothing guarantees that a file opened five years from now will still be readable and intact.
One sheet per measurement session, naming conventions that drift, columns that no longer line up. Finding a value six months later becomes an investigation.
Which CRM, which standard, which uncertainty for this batch? That information rarely sits next to the data, which undermines reproducibility and review.
Every isotope diagram is reconstructed by hand for each manuscript, with the transcription errors that invites.
A proprietary format or a plain spreadsheet says nothing about file integrity. A cell changed by mistake goes unnoticed.
Essential brings together in a standalone application everything a research lab needs day to day: a database, a spreadsheet wired to that database, its geochemical formulas, the mapping of its sites and its publication figures. The scope covers isotope, elemental and molecular geochemistry, it is fixed and identical to the paid editions for everything related to data entry.
Enter and structure your samples with the same depth as the professional editions. Isotope, elemental and molecular geochemistry supported, with no volume limit.
Not a separate file: a spreadsheet connected to the database, where your geochemical formulas recompute the moment the data changes. Extensible through plugins.
Your certified reference materials and standards live next to the measurements they calibrate, and standardization is applied automatically to your batches.
Build your diagrams straight from the database, with no re-entry, from templates designed for manuscripts, and export them in high resolution.
Place your sampling sites back in space and read the geographic distribution of your values straight from your database.
Keep and share your datasets in an open, verifiable and durable format. An ISOF file stays readable and its integrity remains checkable, without depending on IsoFind.
A few views of the application in everyday use.
A spreadsheet can line up numbers. It knows nothing about your standards, your delta conventions or the integrity of your files. Essential is built around the isotopic object itself.

Essential is a standalone application, compiled separately, with its own scope. It is not an evaluation version that locks after thirty days, nor a demo dotted with greyed-out modules. What you install today stays free and complete.
No key to buy, no account to create, no renewal. You download, you install, you work.
No sample ceiling, no watermark on exports, no hidden throttling of the Essential scope.
No telemetry, no usage tracking, no advertising. Your data stays on your machine, full stop.
Fully functional with no internet connection, suited to isolated machines and sensitive environments.
Native Windows application. Linux and macOS versions are coming, not available yet.
The ISOF format is open and independent of the commercial range. Your archives depend on no vendor.
No trackers, no advertising, no hidden subscription.
Research handles sensitive data before publication. Essential was built so that it never leaves your machine without your explicit decision.
No copy is sent to a server, no dependency on an online service to open or edit your datasets.
The ECDSA signature of an ISOF file detects any tampering on opening. Altered data no longer goes unnoticed.
The format is open and documented, published under the MIT license. Any system can read and verify an ISOF file, even without IsoFind.
Essential offers the same data entry depth as the professional editions. The day you need advanced geochemical analysis, 3D simulation or certifiable reports, you move to the generalist IsoFind edition without re-entering or converting your data. Your samples, your CRMs and your standards come with you.
Free for life, complete within its scope, sovereign. The right starting point for research and teaching.
For Windows. Linux and macOS versions coming. No license required.
