Relay
Most automation tools pretend your team doesn’t exist. They expect every task to be handled by bots, running in perfect silence, no questions asked. But that’s not how real work works. Someone always needs to review a draft, approve a refund, sanity-check what the AI spat out, or just… pause and think.

It’s automation with brakes. And judgment. And people in the loop who actually know what they’re doing.
You still get your triggers, actions, integrations, all the usual stuff. Relay connects to Google Workspace apps, Notion, Slack, Salesforce, the works. But the difference is, you can drop in a human whenever it matters. Need to rewrite the AI’s response before it hits a customer’s inbox? You can. Want to insert a manager into the middle of a hiring workflow to give the final go-ahead? Also doable.
Teams use it for all kinds of weird, messy ops stuff. Triage support tickets. Screen inbound demo requests. Monitor LinkedIn posts for decent marketing hooks. It’s the kind of tool that starts small, one task you’re sick of doing, and then ends up quietly running your team’s spine.
If Zapier is duct tape, Relay is more like a switchboard operator. Still fast, still efficient, but there’s a human behind the line if you need one.
