Grammarly announced its acquisition of Coda on December 17, 2024, in a move to expand beyond writing assistance and build a broader AI productivity suite. Coda co-founder and CEO Shishir Mehrotra was named CEO of the combined company, while Grammarly CEO Rahul Roy-Chowdhury stepped down. The financial terms were not disclosed. The deal invited comparisons with Notion, but the companies described a wider ambition: bring writing assistance together with collaborative documents, data, and workflows. Since then, Grammarly has adopted the Superhuman name and placed Coda within a broader product suite.
What Grammarly announced
Grammarly said it would acquire Coda, the collaborative-document and productivity company founded by Shishir Mehrotra and Alex DeNeui. Coda described the transaction as a merger in parts of its announcement; Grammarly and contemporary coverage generally called it an acquisition. At the time, the combined company was expected to retain the Grammarly name, with the transaction expected to close in January 2025, according to contemporary reporting.

The companies did not disclose a purchase price. Coda had reached a reported $1.4 billion valuation in 2021, but that figure is not the acquisition price. Thurrott reported both the undisclosed deal terms and Coda’s earlier valuation.
What Coda brought to Grammarly
Coda was more than a note-taking app. Its workspace combined documents with tables, database-like information, forms, buttons, automations, integrations, and team workflows. That structure gave teams a place to organize information and act on it, rather than only draft and edit text.

Coda also described Coda Brain as an AI assistant that could work across more than 800 privacy-aware integrations. That is Coda’s own figure, not an independently audited count. The company said Grammarly had 40 million active users and worked across more than 500,000 applications and websites—also company-provided figures. Together, those products represented different strengths: Coda supplied a configurable workspace, while Grammarly supplied writing help across many existing tools. Coda’s announcement outlined the products and these figures.
Why the deal made strategic sense
Grammarly’s established product helped people write, rewrite, adjust tone, and use generative-AI features in the applications where they already worked. Coda offered a more persistent team environment in which documents, structured data, and processes could live together. The combination could move Grammarly’s ambition from improving a sentence to assisting with the surrounding work: finding context, organizing information, and helping a team complete a workflow.
That complementarity is a strategic interpretation, not a claim that the companies disclosed every element of their rationale. Their announcement did, however, explicitly describe an AI-native productivity suite and discuss bringing Coda Docs together with Grammarly Assistant. The announcement set out the product-combination goal.
Was Grammarly trying to take on Notion?
Notion is a reasonable comparison because it, like Coda, serves teams that want collaborative documents, structured information, shared knowledge, and lightweight workflows. Coda also overlaps conceptually with database and project-management products. Acquiring Coda gave Grammarly a route into the wider all-in-one workspace category.

Still, “take on Notion” is competitive shorthand, not the companies’ stated product brief. Their announcement emphasized an AI-native productivity suite that would connect writing assistance, documents, integrations, and workflows—not a declared Notion replacement. Thurrott’s headline used the Notion framing, while the announcement described the broader ambition.
The leadership change and product plan
Coda co-founder and CEO Shishir Mehrotra became CEO of the combined company, while Grammarly’s Rahul Roy-Chowdhury left the company. Placing Mehrotra in the top role signaled that Coda’s workspace and AI direction would be central to the company’s next phase, rather than treated as a small add-on. The departure was reported by Thurrott.
The December 2024 announcement described a phased approach:
- Continue operating the existing products.
- Unify Coda Docs and Grammarly Assistant.
- Gradually weave the products into a broader productivity suite.
Those were announced plans, not proof that a fully integrated product existed at the time. Later product positioning shows a broader suite taking shape, but it does not establish that every integration was delivered exactly as originally described.

How the strategy evolved into Superhuman
On October 29, 2025, Grammarly announced that the company would be called Superhuman. Its suite brought together Superhuman Go, Grammarly, Coda, and Mail. The company’s support pages describe Coda’s document product as becoming Superhuman Docs and characterize it as a collaborative workspace for documents and workflows. See What is Superhuman? and Introducing the Superhuman suite.
This later structure suggests the acquisition was not simply a bid to bolt a Notion-style editor onto Grammarly. It became part of a broader effort to package writing, documents, email, and AI assistance across applications. That is an inference from the suite’s product lineup, rather than evidence that all four products already operate as one seamless application.

The rebrand and suite announcement do not, by themselves, mean existing customers were forced to migrate or automatically enrolled in a bundle. Grammarly’s support documentation says existing functionality and documents were not supposed to disappear because of the name change; standalone products remained available, and existing customers were not automatically moved into the suite. Subscription amounts generally remained unchanged unless a customer chose to switch. Check the current Superhuman overview and billing and subscription FAQs for account-specific details.
- Coda documents: The company’s documentation describes the product transition, but the acquisition announcement did not mean documents would immediately move into a new product.
- Separate products and accounts: Grammarly, Coda/Docs, and Mail remained available as standalone products even as the company offered a bundle. Do not assume that accounts or subscriptions from different products consolidate automatically.
- Plan eligibility: The billing FAQ says Coda Team customers are eligible to upgrade only to Superhuman Business, while Coda Pro customers can choose Superhuman Pro or Business. Check the support page for the applicable terms before changing a plan.
- Organization controls: Teams should verify administration, permissions, identity, and billing arrangements for their own accounts rather than assuming one suite subscription resolves every governance need.
What could make the strategy work—or falter
The acquisition gave the company a broader product foundation and a potential way to connect workplace context with AI assistance. Its challenge is execution: a writing assistant, document workspace, email product, and cross-application AI helper can feel like a collection of separate tools if identity, permissions, billing, and user experience do not fit together.
- Product sprawl: Customers who need only grammar correction may see little value in paying attention to a larger suite.
- Integration and governance: Bringing documents, email, organizational data, and third-party integrations into AI-assisted workflows raises practical questions about permissions, security, and data governance.
- Brand and migration friction: The Superhuman name and Coda’s product evolution may confuse customers attached to familiar brands or existing workflows.
- Category competition: Coda gives the company workspace capabilities, but the acquisition alone does not establish parity with Notion or other established work platforms.
For personal-finance-minded buyers and small teams, the practical test is whether they will use enough of the included products to justify choosing a bundle. A person who mainly wants writing feedback may not need a broader productivity suite; a team already paying for documents, AI assistance, and email from separate providers may value consolidation. Compare the actual features and current terms on the Superhuman plans page and Grammarly plans page before switching.
