Alhena AI vs Grammarly: at a glance
What is Alhena AI?
A vendor running a public benchmark on its own category, and publishing where everyone fails.
Alhena AI's feed is a research blog, not a changelog, but it is unusually structured for one: since late July it has run a single continuing study in which 15 live AI shopping agents are tested as ordinary shoppers on real storefronts. The findings are consistent and unflattering to the category - all 15 can answer questions, 9 can sell, 4 can complete a return or order change, and 1 remembers a shopper across sessions. Recent instalments break the results down by 11 verticals and by a specific task, foundation shade matching from a selfie, where five agents ignored the image entirely.
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.

Alhena AI
5.0AI-ASSISTANTS
A vendor running a public benchmark on its own category, and publishing where everyone fails.
◆ Current state
Alhena AI's feed is a research blog, not a changelog, but it is unusually structured for one: since late July it has run a single continuing study in which 15 live AI shopping agents are tested as ordinary shoppers on real storefronts. The findings are consistent and unflattering to the category - all 15 can answer questions, 9 can sell, 4 can complete a return or order change, and 1 remembers a shopper across sessions. Recent instalments break the results down by 11 verticals and by a specific task, foundation shade matching from a selfie, where five agents ignored the image entirely.
◆ Where it's heading
The blog is building a capability ladder - Answer, Recommend, Sell, Act, Remember - and using it to argue that architecture, not category difficulty, decides where an agent stops. That framing does competitive work: it defines the axis on which agents are compared, places memory and task completion at the top, and reports that almost nothing on the market reaches them. Nothing here describes Alhena's own product releases, so the feed shows the argument the company is making rather than what it is shipping.
◆ Prediction
The benchmark series looks set to continue with further vertical and task cuts against the same 15-agent panel. A refreshed run showing movement on the Act and Remember rungs would be the natural next instalment, though these entries do not say when it is due.
Grammarly
2.5AI-ASSISTANTS
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.
