Every number on PricingLog is supposed to earn your trust the same way: it was captured by a person, on a stated date, with saved evidence behind it. This page explains exactly how that works — and, just as importantly, what this site does not claim.

How prices are captured

I check each vendor's own pricing page directly, rendered from a US location, in a clean browser profile with no account logged in. Many vendors show different prices or currencies to visitors from different countries, so every price on this site follows one convention: US pricing, in USD, excluding tax. Both monthly and annual billing views are captured, because the gap between them is one of the most common sources of confusion in third-party pricing articles.

For every capture I save a full-page screenshot and a copy of the page HTML, filed by tool and date. Those files are the evidence behind each number. If a vendor appears to be showing different prices to different visitors (A/B testing), I note that on the page rather than presenting one variant as the only truth.

What "Last verified" means

Data pages carry a visible "Last verified" date. That date changes only when I have actually re-checked the numbers against the vendor's live pricing page — it is never bumped automatically to look fresh. If a date looks old, that is honest information too: it tells you exactly how stale the data might be. Prices can change at any moment between checks; always confirm on the vendor's site before paying.

How costs are normalized

Vendors price in incompatible units — words, credits, scans, seats — which makes sticker prices almost useless for comparison. Where this site shows a normalized cost, it uses these exact formulas:

If an input is unknown, the cell shows a dash — never a guessed number and never $0. Plans without public pricing ("contact sales") are labelled as exactly that.

Pricing history and the Wayback Machine

Historical prices come from two sources: my own dated captures going forward, and the Internet Archive's Wayback Machine going backward. Wayback snapshots are used only when the archived page actually shows rendered prices — many archived copies of modern pricing pages are empty shells, and those are not evidence. Every history entry links or refers to its source. History is append-only: past entries are never rewritten. If an entry turns out to be wrong, a correction entry is added; the record of the mistake stays.

Update cadence

Tracked pricing pages are checked on a weekly cycle, with a full re-check of each tool at least monthly. Detected changes are logged in the changelog with the old value, the new value, the date, and evidence. Weeks with no detected changes are logged too — a null result is still a result, and it proves the checks happened.

Corrections

If you find an error — a wrong price, an outdated limit, a missed change — please report it. I verify reports against the vendor's live page and aim to fix confirmed errors within 48 hours, with the correction noted openly in the changelog. Vendors are welcome to use the same process; corrections require evidence, not just a request, and accurate historical records are not removed on request.

Neutrality and money

Some links on this site may become affiliate links over time — the disclosure page lists exactly which programs are active (at launch: none). The rule that governs all of it: no commercial relationship ever changes a number, a table, or an ordering. Tables sort by data — price, cost per unit, verification date — never by commission. Tools with no affiliate program get identical treatment.
