A computer code for $\beta$-spectrum construction of 1300$+$ radionuclei has been created. The tools use the experimental nuclear data adopted and compiled in the ENSDF file and experimental or estimated parameters of shape factors. The final uncertainty on the calculated $\beta$-spectrum branch tries to deal with uncertainties on the radiation probability, the endpoint energy, and the shape factor parameters.
