What is Grammarly?

Authorship expands into Blackboard, extending the one product built for the AI-in-classroom problem.

Grammarly's feed is mostly evergreen writing-advice content - salary negotiation emails, follow-ups, email blasts - with occasional product and research posts mixed in. The product thread that matters runs through Grammarly Authorship, which records how a piece of writing was produced so instructors can see what a student actually did. Authorship launched in beta inside Google Docs and now reaches Blackboard, putting it inside a major LMS rather than a document editor.

What is Claude?

Claude layers Salesforce skills and Fable 5.1 onto an accelerating enterprise platform push.

Claude is shipping at pace across three axes simultaneously: new frontier models (Fable 5.1, Mythos 5.1, Opus 5 in the past two months), enterprise infrastructure (HIPAA self-serve, smart reports, security scanning for plugins), and agentic integrations (Cowork, persistent memory, and now a Salesforce plugin with 37 pre-built sales skills). The Salesforce integration is the product's first explicitly vertical-specific plugin — bundling domain-tailored skills rather than leaving configuration to end users. Smart reports add the cost-and-usage telemetry that IT departments need to renew and expand contracts.

Authorship expands into Blackboard, extending the one product built for the AI-in-classroom problem.

◆ Current state

Grammarly's feed is mostly evergreen writing-advice content - salary negotiation emails, follow-ups, email blasts - with occasional product and research posts mixed in. The product thread that matters runs through Grammarly Authorship, which records how a piece of writing was produced so instructors can see what a student actually did. Authorship launched in beta inside Google Docs and now reaches Blackboard, putting it inside a major LMS rather than a document editor.

◆ Where it's heading

Grammarly has picked writing transparency as its answer to AI in education, and it is distributing that feature by integrating with the systems where academic work is already submitted. That is a different bet from AI detection, which it notably does not sell here: Authorship documents process rather than judging output. The accompanying research and educator content is doing the work of legitimizing that position with the institutions who make the purchasing decision.

◆ Prediction

Expect Authorship to keep landing in further LMS and submission platforms on the Blackboard pattern, and more peer-reviewed or institutional evidence published alongside those integrations.

Claude layers Salesforce skills and Fable 5.1 onto an accelerating enterprise platform push.

◆ Current state

Claude is shipping at pace across three axes simultaneously: new frontier models (Fable 5.1, Mythos 5.1, Opus 5 in the past two months), enterprise infrastructure (HIPAA self-serve, smart reports, security scanning for plugins), and agentic integrations (Cowork, persistent memory, and now a Salesforce plugin with 37 pre-built sales skills). The Salesforce integration is the product's first explicitly vertical-specific plugin — bundling domain-tailored skills rather than leaving configuration to end users. Smart reports add the cost-and-usage telemetry that IT departments need to renew and expand contracts.

◆ Where it's heading

Claude is converging on a work-OS model where it sits persistently inside a user's active tools — CRM, docs, email — rather than requiring a context switch to a chat window. Memory spanning Cowork, Salesforce skills that surface pipeline data in real time, and team-level reporting that tells managers what their organizations accomplished together point toward a coherent platform vision. The next logical steps are more vertical plugins following the Salesforce pattern and deeper integration with the underlying data those platforms hold.

◆ Prediction

The Salesforce plugin will be followed by integrations for adjacent enterprise tooling — HubSpot, Jira, or ServiceNow — using the same pattern of pre-built domain skills. A Cowork-plus-plugin stack is becoming the enterprise pitch, and more compliance certifications will follow HIPAA to broaden the addressable regulated-industry market.
