The AI's one-line headline fix for some of the biggest names. You don't have to agree; the point is how often "clever" beats "clear".
slack.com now: “All your people and AI agents working together”
“Get work done faster, with AI that knows your whole business”
It names a concrete outcome and the differentiator (business context) instead of a generic vision.
airtable.com now: “All your teams, all their workflows—connected in one workspace”
“Build the custom apps your team needs, without writing code”
It names a specific outcome (custom apps) and the main objection (no code) instead of an abstract ideal.
intercom.com now: “A complete system for AI and human customer service”
“Resolve more customer questions automatically, without adding headcount”
It names a concrete outcome buyers care about instead of describing a product category.
zapier.com now: “Welcome to automation in the agentic era”
“Build AI workflows that connect your apps and run on their own”
It states the concrete outcome and product category instead of a generic era-based greeting.
cursor.com now: “Cursor is your coding agent for building ambitious software.”
“Hand your coding tasks to AI agents and ship features in hours.”
It names the concrete outcome and the action the visitor takes, instead of an abstract aspiration.
notion.com now: “It’s time.”
“Your calendar and Notion workspace, finally in one place.”
It names the two things being combined and the outcome, instead of a slogan a visitor must decode.
asana.com now: “Supercharge your teams with AI”
“Turn your team's plans into work that gets done, with AI doing the follow-up”
It names a concrete outcome and the mechanism, replacing a generic AI promise with a specific one.
dropbox.com now: “One place to store, share, and collaborate”
“Send, sign, and review files without leaving your workflow”
It names concrete actions and an outcome, which makes the value tangible in the first five seconds.
The best-scoring pages say what the product is and who it's for in plain words above the fold, show one obvious next step, and back it up with specific proof. The weakest lead with a slogan, offer two or three equal CTAs, and make the visitor work out what the product does. Fixing the headline alone fixes the #1 problem on 80% of pages.
