Alhena AI vs btw: at a glance
What is Alhena AI?
Alhena is building the scoreboard for shopping agents it also competes in.
The feed has consolidated around one piece of original research: a 2026 stress test running fifteen live AI shopping agents through real storefronts as ordinary shoppers. The headline numbers repeat across several posts — all fifteen could answer questions, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Around that sit vertical censuses of who is actually live in health and wellness retail, an attribution model for measuring agents, and comparison pages against AI visibility platforms including Profound.
What is btw?
btw is turning into an agentic R harness that no longer needs you to be in R
btw assembles context about an R session — packages, documentation, files, data frames — and hands it to an LLM through ellmer, with btw_app() as a chat interface. Over the last year it has grown well past context assembly: LLMs can document, check, test and measure coverage of a package, read CLAUDE.md and AGENTS.md as project context, fetch skills from packages or GitHub, and inspect the source of any installed namespace. Much of this is now reachable from a terminal CLI rather than only from an R prompt.

Alhena is building the scoreboard for shopping agents it also competes in.
◆ Current state
The feed has consolidated around one piece of original research: a 2026 stress test running fifteen live AI shopping agents through real storefronts as ordinary shoppers. The headline numbers repeat across several posts — all fifteen could answer questions, nine could sell, four could complete a return or order change, and one remembered the shopper on a return visit. Around that sit vertical censuses of who is actually live in health and wellness retail, an attribution model for measuring agents, and comparison pages against AI visibility platforms including Profound.
◆ Where it's heading
Alhena is defining the category's measuring stick and choosing metrics where most competitors fail — acting rather than answering, and remembering across sessions. Publishing a dated census that separates shipped assistants from announced intent serves the same purpose: it establishes Alhena as the arbiter of what counts as live. The vertical focus on supplements and wellness, with its FDA claims boundary and subscription economics, looks like a deliberately chosen beachhead rather than broad retail coverage.
◆ Prediction
Expect the stress test to become a recurring dated benchmark with more agents and more verticals, and for the act-and-remember gap it identifies to be positioned as what Alhena's own product closes.

btw is turning into an agentic R harness that no longer needs you to be in R
◆ Current state
btw assembles context about an R session — packages, documentation, files, data frames — and hands it to an LLM through ellmer, with btw_app() as a chat interface. Over the last year it has grown well past context assembly: LLMs can document, check, test and measure coverage of a package, read CLAUDE.md and AGENTS.md as project context, fetch skills from packages or GitHub, and inspect the source of any installed namespace. Much of this is now reachable from a terminal CLI rather than only from an R prompt.
◆ Where it's heading
The direction is from describing a session to operating on it, and from inside R to outside it. Each release adds either a tool group that lets a model do something (document, check, test, cover; read namespace source; fetch skill resources) or a CLI command that removes the need to start R first. The 1.2.0 tool renaming — session becoming sessioninfo, search becoming cran, files_read_text_file becoming files_read — reads as the naming cleanup you do when you expect a lot more tools to follow.
◆ Prediction
The CLI has been absorbing one tool family per release (skills, then pkg desc and pkg src) while the R-side tool groups stay ahead of it, so the next releases likely continue exposing existing tool groups as terminal commands rather than adding new capabilities.
