# Brainbits vs Document Lens

Both are free to download. Brainbits sells 3 in-app purchases, starting at $3.99 per month and Document Lens sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Brainbits ships an update every 3 days, Document Lens every 10 days. The most recent releases landed on September 30, 2026 and September 10, 2026 respectively.
