What is Chord?
Chord's assistant can now write to the team's knowledge base, not just read from it.
Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.
What is epikit?
epikit narrows to field-epidemiology helpers, handing proportions to a sibling package
epikit is a set of small helpers for applied epidemiology in R — age categorisation, date reconstruction from partial records, and related field-data chores, developed in the R4Epis orbit. Version 0.2.0 moved the proportion functions out to epitabulate, improved how find_date_cause(), find_start_date() and find_end_date() handle dates falling outside the period, and added a floor argument to age_categories() so the lowest band reads as under one rather than zero to zero.

Chord's assistant can now write to the team's knowledge base, not just read from it.
◆ Current state
Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.
◆ Where it's heading
The arc runs from answering questions to acting and now to accumulating. Each release has closed one gap in that loop — answers that show their reasoning, then grounding in the customer's definitions, then feedback capture, then building audiences directly, and now retaining what it learns for the whole team. The rename from Copilot signals the assistant is being treated as the product surface rather than an add-on to it. Release notes arrive on a strict two-week cadence and the feed truncates their bodies, so specifics beyond the headline features are not visible.
◆ Prediction
Acting on that accumulated memory is the natural next step, since the assistant can already build audiences and now retains definitions across conversations.

epikit narrows to field-epidemiology helpers, handing proportions to a sibling package
◆ Current state
epikit is a set of small helpers for applied epidemiology in R — age categorisation, date reconstruction from partial records, and related field-data chores, developed in the R4Epis orbit. Version 0.2.0 moved the proportion functions out to epitabulate, improved how find_date_cause(), find_start_date() and find_end_date() handle dates falling outside the period, and added a floor argument to age_categories() so the lowest band reads as under one rather than zero to zero.
◆ Where it's heading
The package is being scoped down rather than built out. The 0.1.3 restructuring and the 0.2.0 handover of proportions to epitabulate are the same move made twice: push functionality into the package where it belongs and keep epikit to the toolkit that field epidemiologists reach for directly. The rest of the history is dependency compatibility work against dplyr and tibble.
◆ Prediction
With proportions gone and dependencies trimmed, the remaining functions cluster tightly around dates and age bands, so further refinement of the date-reconstruction helpers is more likely than new capability areas.
