ToolRank
ToolRank is ToolPotion’s proprietary ranking engine.
It continuously evaluates hundreds of signals across the open web — real traffic and popularity, audience and community strength, authority and longevity, adoption and engagement — processing millions of data points to place every tool where it has earned to be.
Every AI type is measured by its own tailored model: what proves traction for a SaaS app is not what proves it for an open-source framework or a creator channel. Missing a platform never counts against a tool — ToolRank judges the evidence that exists.
No paid placement. No self-reported numbers. Rankings refresh monthly as ToolRank re-measures the market.

Editor's round-up
The board mixes two jobs. For marketing, Brevo runs email and SMS campaigns with automation and CRM, and Mailchimp does the same with behavior-based targeting, so pick either if you send to lists rather than individuals. For everyday inbox work, the Gmail helpers lead: GPT for Gmail drafts, rephrases, and translates using models like Gemini, ChatGPT, and Claude, and ChatGPT for Gmail is a free extension for faster writing.
For summarizing, Concisely condenses emails to a single sentence, and EmailWhiz suggests replies and pulls out tasks and contacts. Fyxer goes further, organizing the inbox and drafting replies in your own voice. Outlook users have Boomerang and OfficeAI, and Missive is the pick for teams sharing an inbox.
Choose by the task. Campaigns point to Brevo or Mailchimp, and daily replies point to GPT for Gmail or Fyxer.
