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 opencode?

opencode keeps publishing process-daemon patches on protocol 8.

The newest tags are npm publishes of the process daemon: @opencode/pty reached 0.5.0 on protocol 8 on November 5 and got 0.5.1 and 0.5.2 patches on November 11. Before that came 0.3.x and 0.4.0 on protocol 7, a CI pin and an app animation change. None of these tags describe a change to the agent itself.

2.5

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.

AI-ASSISTANTS
5.0

opencode keeps publishing process-daemon patches on protocol 8.

◆ Current state

The newest tags are npm publishes of the process daemon: @opencode/pty reached 0.5.0 on protocol 8 on November 5 and got 0.5.1 and 0.5.2 patches on November 11. Before that came 0.3.x and 0.4.0 on protocol 7, a CI pin and an app animation change. None of these tags describe a change to the agent itself.

◆ Where it's heading

The feed shows V2 infrastructure settling into separately versioned components. The protocol bump suggests the terminal layer the agent uses is still changing under the hood.

◆ Prediction

The entries don't show the next user-facing release; a CLI or extension update that adopts protocol 8 is the likely next visible tag.
