Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
BuzzSumo

Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
BuzzSumo
Visible enterprise brands and a large journalist database suggest meaningful scale, but no customer count is claimed.

POP Pilot is described as an AI assistant/agent inside POP: https://pageoptimizer.pro/
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
BuzzSumo
Automation can feed dashboards and alerts, but human-led research and outreach remain central.
The API page says users can automate reporting and dashboards, while the homepage describes discovering and pitching journalists; no autonomous end-to-end execution is claimed (https://buzzsumo.com/buzzsumo-api/; https://buzzsumo.com/).
