Paste an AI answer about retirement accounts, HSAs, Social Security or federal tax. Every official figure in it is checked against IRS and SSA figures for the year it's about, with the right number and its source. The check runs in your browser; the answer never leaves it.
Runs the real fin-assist package from PyPI, in your browser with Pyodide: the same code as pip install fin-assist. Covers the figures in the registry; a figure it doesn't know is left alone, not guessed. On the latest blind test set it caught 31 of 46 stale or wrong figures, so a PASS is not a guarantee (results, misses included).
