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 geodist?
geodist stays dependency-free and fast, and warns you when 'cheap' distances stop being honest.
geodist computes geodesic distances between coordinate pairs in C with no dependencies, offering several measures that trade accuracy for speed — including a 'cheap' approximation used by default. The API is small and largely finished; 0.1.0 added geodist_min() for nearest-match lookups and 0.1.1 is a compiler warning fix.

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.
geodist
0.0ANALYTICS
geodist stays dependency-free and fast, and warns you when 'cheap' distances stop being honest.
◆ Current state
geodist computes geodesic distances between coordinate pairs in C with no dependencies, offering several measures that trade accuracy for speed — including a 'cheap' approximation used by default. The API is small and largely finished; 0.1.0 added geodist_min() for nearest-match lookups and 0.1.1 is a compiler warning fix.
◆ Where it's heading
Development has been about making the speed-accuracy trade visible rather than hiding it. The 0.0.6 release added messages telling users to pick a different measure once the default cheap approximation is applied beyond 100km, where its error stops being negligible. Around that, the work is input handling — tibble support, better lon/lat column matching, vector inputs — and hardening the C code. It is a package that treats being small and correct as the feature.
◆ Prediction
Expect continued low-frequency maintenance: compiler warnings and geodesic source updates account for three of the last six releases, and the function surface has grown by only two entries in five years.
