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 InvokeAI?

InvokeAI 7 alpha 3 turns boards into shared, role-gated spaces and adds Qwen-Image-2.1.

InvokeAI is a local-first image and video studio three alphas into a v7 rewrite. Alpha 1 replaced the tabbed UI with autosaving projects and a widget workbench; alpha 2 added MySQL/MariaDB backends and per-project boards. Alpha 3 adds board sharing with Viewer, Contributor, Editor and Owner roles, keeps each member's settings separate inside a project, and brings back a long list of legacy features. It also adds Qwen-Image-2.1 and an opt-in SageAttention backend that cuts large NVIDIA generations by 15–35%.

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.

6.3

InvokeAI 7 alpha 3 turns boards into shared, role-gated spaces and adds Qwen-Image-2.1.

◆ Current state

InvokeAI is a local-first image and video studio three alphas into a v7 rewrite. Alpha 1 replaced the tabbed UI with autosaving projects and a widget workbench; alpha 2 added MySQL/MariaDB backends and per-project boards. Alpha 3 adds board sharing with Viewer, Contributor, Editor and Owner roles, keeps each member's settings separate inside a project, and brings back a long list of legacy features. It also adds Qwen-Image-2.1 and an opt-in SageAttention backend that cuts large NVIDIA generations by 15–35%.

◆ Where it's heading

Each alpha moves InvokeAI further from a single-user desktop app toward a shared workspace: pluggable databases, then project boards, now per-role permissions and per-member settings that the notes call groundwork for collaboration later in 7.x. Model support keeps pace in parallel, and the priority is running new models on existing hardware through GGUF, fp8 and quantized attention. Restoring legacy features signals the team wants v7 at parity before it asks v6 users to migrate.

◆ Prediction

Expect alpha 4 within about a week, with more parity restoration and collaboration plumbing; project file formats may break again, since alpha 3 already did. The entries still give no beta or stable date.
