Price change log
Tracking started on Oct 8, 2026. Every confirmed change to a plan, price or free tier will be listed here with its date.
How this table is built
Each row comes from the vendor's own pricing page, read on the date shown, with a screenshot kept as evidence. We never use app-store purchase lists or other review sites for prices, because they often show plans a company no longer sells. "$ / 1k words" divides the monthly price by the monthly word allowance, so it assumes you use the whole allowance. Where a page showed prices in a currency other than US dollars from our location, we show that currency until a US check confirms the dollar price.
