What is Alhena AI?

Alhena is slicing one benchmark study into a month of posts, one finding each.

Alhena AI sells shopping agents for ecommerce, and its feed is currently one piece of research being published a finding at a time. The 2026 stress test ran fifteen live AI shopping agents through real storefronts as ordinary shoppers: all fifteen could answer, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Four of the last five posts restate those same numbers from a different angle — the answer-to-act gap, memory, and now a taxonomy separating personalisation engines, AI search and agentic assistants by which ceiling each hits.

What is Yellow.ai?

Two platform rewrites in four months, then the feed went quiet.

Yellow.ai spent early 2026 relaunching itself twice: Nexus in February as an agentic interface meant to replace dashboard-driven SaaS, and Nexus Vox in May as a voice stack built end to end rather than assembled from separate ASR, LLM and TTS vendors. Around those launches sit a PCI-DSS v4.0.1 service-provider validation for North America and PRISM, an in-house research effort on prompt drift. The feed stops in June, so the last two months are unobserved.

Alhena is slicing one benchmark study into a month of posts, one finding each.

◆ Current state

Alhena AI sells shopping agents for ecommerce, and its feed is currently one piece of research being published a finding at a time. The 2026 stress test ran fifteen live AI shopping agents through real storefronts as ordinary shoppers: all fifteen could answer, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Four of the last five posts restate those same numbers from a different angle — the answer-to-act gap, memory, and now a taxonomy separating personalisation engines, AI search and agentic assistants by which ceiling each hits.

◆ Where it's heading

The taxonomy post is the tell: by naming three technologies that share a chat box and assigning each a hard ceiling — Recommend, Sell, Act and Remember — Alhena turns its benchmark into a category ladder with its own product at the top rung. Around that sit dated vertical censuses separating shipped assistants from announced intent, an attribution model, and comparison pages against AI visibility tools including Profound. None of this is product news; the last shipped features in the feed were the embeddable agents in July.

◆ Prediction

Expect the study to keep yielding one post per finding until it is exhausted, then a refreshed census or a second vertical on the same template; actual release notes will keep arriving only as launch posts between research runs.

Two platform rewrites in four months, then the feed went quiet.

◆ Current state

Yellow.ai spent early 2026 relaunching itself twice: Nexus in February as an agentic interface meant to replace dashboard-driven SaaS, and Nexus Vox in May as a voice stack built end to end rather than assembled from separate ASR, LLM and TTS vendors. Around those launches sit a PCI-DSS v4.0.1 service-provider validation for North America and PRISM, an in-house research effort on prompt drift. The feed stops in June, so the last two months are unobserved.

◆ Where it's heading

The argument running through every post is that stitched-together AI stacks fail on the hard cases — non-English voice, long-running procedures, silent prompt regressions — and that owning the whole pipeline is the fix. The APAC-language framing on Nexus Vox and the PRISM reliability work point the same way: competing on the calls that currently get abandoned rather than on demo quality. Compliance validation suggests the target buyer is enterprise and regulated.

◆ Prediction

The consistent pairing of a launch with a reliability or compliance artifact suggests the next visible move is Nexus Vox availability or certification beyond APAC, or PRISM surfacing as a customer-facing drift monitor. The June cutoff in this feed means that is inference from a stale window, not a read on current activity.
