What is Dosu?

Dosu is folding agent session logs into the knowledge base it already maintains.

The August Drop turns old agent logs into Dosu knowledge, adds configuration from chat, and surfaces what the agents actually read. It follows Decant by a week — the local tool that parses Claude Code and Codex session logs into per-session cost and activity numbers — so the two releases sit on the same axis from opposite ends: Decant reads the logs on the developer's machine, Dosu now ingests them as a knowledge source. The monthly Drop format continues, with July's removing the waitlist and simplifying Knowledge Cache tools.

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.

Dosu vs Grammarly: editorial side-by-side

6.3

Dosu is folding agent session logs into the knowledge base it already maintains.

◆ Current state

The August Drop turns old agent logs into Dosu knowledge, adds configuration from chat, and surfaces what the agents actually read. It follows Decant by a week — the local tool that parses Claude Code and Codex session logs into per-session cost and activity numbers — so the two releases sit on the same axis from opposite ends: Decant reads the logs on the developer's machine, Dosu now ingests them as a knowledge source. The monthly Drop format continues, with July's removing the waitlist and simplifying Knowledge Cache tools.

◆ Where it's heading

Dosu started by maintaining repository knowledge and is now positioning agent output as an input to it. That closes a loop: agents read the docs Dosu maintains, and their sessions become material Dosu learns from. The Drops also show a steady flattening of setup friction — waitlist removed, libraries and agents overhauled, configuration moved into chat — which is the pattern of a product trying to shorten time-to-value rather than widen its feature surface.

◆ Prediction

Expect the log ingestion and Decant's cost data to converge into one view of what agents cost against the maintenance work Dosu absorbs, which the August Drop's impact reporting now partially supplies.

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.
