Every price point above is copied from the vendor's own pricing page and carries the date it was checked on the individual tool page — we do not fill gaps from third-party roundups. Where a figure could not be verified against an official source, the tool page says so instead of guessing.

When you compare Personal AI Agents tools, the fields that decide the outcome are the ones this index actually stores: whether a free plan exists and what it limits, the published entry price and how it bills (per seat, per month, per workspace), what the trial covers, which of the six index dimensions the tool scores on, when each figure was last checked against the official page, and which alternatives sit in the same category. Each tool page prints those fields with its own verification date, the Personal AI Agents comparison pages put two products side by side on the same fields, and the list pages rank the category against the rest of the index — so you can move from a shortlist to a decision without opening a vendor's sales page.
