What is Dovetail?

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

What is tulpaObs?

An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.

tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.

Dovetail vs tulpaObs: editorial side-by-side

Dovetail
ANALYTICS
5.0

Dovetail spent July opening doors to other tools; August is spent making its own rooms easier to enter.

◆ Current state

Dovetail is a customer-research workspace whose center of gravity has moved to chat and agents. July was an integration run — Snowflake into Channels, a Microsoft Copilot connector, MCP tools inside chat, and a one-click menu for sending work out to Linear or Notion. August contains no new reach at all: every release this month files down the chat and Digital Twin surface that those integrations feed.

◆ Where it's heading

The pattern across the last five releases is access, not capability. Digital Twins went from a two-step workaround — make a generic agent, then change its type — to a first-class create option, then gained a share link that lands a recipient in a conversation rather than a configure page. Chat is being simplified along the same line, with a thinner footer and scoped context that survives the jump to fullscreen. Dovetail is preparing these agents for people who will never build one.

◆ Prediction

Expect the sharing path to keep widening — permissions, guest access, or an embed for a twin link — since a link that opens straight into chat only pays off if it can safely leave the workspace.

An occupancy-modeling package that just deleted its own duplicate vocabulary for diagnostics.

◆ Current state

tulpaObs is the ecological occupancy and abundance modeling layer built on the tulpa engine, releasing at high frequency and with version numbers that do not advance monotonically in publication order. The current window covers three strands: a breaking consolidation of its diagnostic surface onto generics the engine now owns, the completion of simulation-based-calibration registration across all 27 model families, and a correctness fix that materially moves previously reported information criteria. Several releases exist only to pin a new engine version and record what that change does when measured from this side.

◆ Where it's heading

The package is systematically removing the parallel names it had accumulated for concepts owned elsewhere, and the registration work is closing rather than expanding — the SBC scope reached its final family in this window. Its cadence is tightly coupled to the engine's, to the point where the interesting content of some releases is a dependency floor plus a measurement. With the breaking rename and the registration scope both behind it, the surface work looks close to finished.

◆ Prediction

Expect the follow-on releases to be consolidation rather than expansion — registry branches, regenerated documentation, engine pins — with the next substantive move most likely a new model family beyond the original registration scope.
