Superhuman

Superhuman is an AI productivity company, formerly known as Grammarly, that builds AI tools which work across the applications people already use. Its suite spans the Grammarly writing assistant, the Coda collaborative workspace and docs product, Superhuman Mail, and Superhuman Go, a proactive AI assistant with first- and third-party agents. The platform integrates with a very large number of applications and websites and serves tens of millions of weekly active users plus enterprise customers. The company is headquartered in San Francisco.

Rather than a single destination app, it puts AI assistance and agents into whatever tool the user is already working in, spanning writing, email, docs, and calendar under one subscription.
