Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Superhuman

Application

GrammarlyApplication

The writing assistant that gave the company its old name: spelling, grammar and tone correction across a million apps and websites, with generative rewrites, plagiarism and AI-text detection on the paid tier.

Superhuman DocsApplication

A collaborative-docs surface where a team's data and AI meet, the renamed successor to the acquired Coda.

Superhuman GoApplication

An AI assistant that works across the applications a person already uses, rather than living in its own chat window.

Superhuman MailApplication

An AI-assisted email client, the product the company was originally named for, now sold as one app inside the Superhuman Platform.

Platform

Superhuman PlatformPlatform

The umbrella under which Superhuman now sells Mail, Docs and Go as one subscription, plus a marketplace of third-party agents and connectors.

Writer

Application

WRITER Enterprise BrainApplication

Universal context layer that grounds AI agents in a company's Agent Memory (captured decisions and preferences) and Company Standards (brand, tone, compliance), listed in WRITER's own top-level product navigation alongside Models, AI Studio, WRITER Agent and WRITER for Slack.

WRITER PlaybooksApplication

Reusable, repeatable workflows in WRITER, so a piece of work done once can be run the same way again.

Platform

WRITER Knowledge GraphPlatform

WRITER's retrieval layer. A specialised LLM reads a customer's own documents, spreadsheets, slides and PDFs and builds a graph of the semantic relationships between them rather than storing vector embeddings, so retrieval can follow multi-hop connections, break a broad question into sub-questions and return specific source citations before WRITER's Palmyra models generate the answer.

WriterPlatform

Enterprise platform for building AI applications and agents on Writer's own models.

No counterpart

Writer sells these in a stack layer with no product recorded for Superhuman yet — nothing on the other side to compare them against.

AI agent

WRITER AgentAI agent

An agent that plans and carries out multi-step work across a customer's own data and tools, under enterprise governance controls.

Agent platform

WRITER AI StudioAgent platform

WRITER's build surface: business teams assemble agents on an interoperable platform while technology teams keep visibility and governance over what ships.
