Biology tools, in one place
Every result shows its work.
Calculators and sequence tools for the bench. Each one names the formula it used and cites where that formula comes from — and none of them send your data anywhere.
From the reagent bottle or supplier datasheet.

Why trust the number
- The formula is on the page
- Under every result sits the expression that produced it, the model chosen where more than one is accepted, and a link to the source. A tool that cannot fill that in does not ship.
- Nothing leaves your browser
- Every calculation runs locally. Unpublished sequences and constructs stay on your machine, because they should never have had to go anywhere in the first place.
- Tested against published values
- Each tool is checked against reference figures from the literature or from established tools, and the checks run on every change. Being wrong once costs more than every feature here is worth.
