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 ravetools?

RAVE's signal-processing toolkit taught base R graphics to render lit 3D brain meshes.

ravetools supplies the signal processing and now the rendering primitives behind RAVE, a suite for analyzing intracranial electroencephalography. Its earlier releases built out Matlab-equivalent filtering, Welch spectra and wavelet tooling; 0.2.6 changes register entirely, adding plot_mesh_dotcloud and plot_mesh_polygon to draw 3D surface meshes in base R graphics with no rgl dependency, plus arbitrary clipping planes and per-mesh alpha.

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.

RAVE's signal-processing toolkit taught base R graphics to render lit 3D brain meshes.

◆ Current state

ravetools supplies the signal processing and now the rendering primitives behind RAVE, a suite for analyzing intracranial electroencephalography. Its earlier releases built out Matlab-equivalent filtering, Welch spectra and wavelet tooling; 0.2.6 changes register entirely, adding plot_mesh_dotcloud and plot_mesh_polygon to draw 3D surface meshes in base R graphics with no rgl dependency, plus arbitrary clipping planes and per-mesh alpha.

◆ Where it's heading

The package is absorbing the visualization layer that RAVE previously delegated to WebGL-backed renderers, and doing it in a way that works in headless and figure-generating contexts. Exporting ensure_mesh3d to coerce mesh3d, ieegio_surface, fs.surface and surf.asc into one canonical form makes ravetools the convergence point for surface formats across the wider toolchain — the sibling ieegio package shipped its own base R plot method within minutes of this release.

◆ Prediction

Expect the base R renderers to pick up the features rgl users would miss next — richer materials, labeling and camera control — and for more of the RAVE stack to route surface handling through ensure_mesh3d.
