Dovetail vs tulpaRatio
A side-by-side editorial comparison of Dovetail and tulpaRatio — release velocity, themes, recent moves, and the top alternatives to consider.
Dovetail vs tulpaRatio: at a glance
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 tulpaRatio?
A Bayesian ratio-modelling package that threw out its Stan dependency and wrote its own sampler
ratiod models ratios, rates and proportions hierarchically, with the stated position that a ratio is a derived quantity and inference should run on the latent numerator and denominator processes rather than their quotient. The 1.0.0 release shipped a native HMC/NUTS backend, removing the Stan dependency that packages in this space normally take as given. Everything since has been sampler optimisation, benchmarked against the Stan implementations it replaced.

◆ 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.

A Bayesian ratio-modelling package that threw out its Stan dependency and wrote its own sampler
◆ Current state
ratiod models ratios, rates and proportions hierarchically, with the stated position that a ratio is a derived quantity and inference should run on the latent numerator and denominator processes rather than their quotient. The 1.0.0 release shipped a native HMC/NUTS backend, removing the Stan dependency that packages in this space normally take as given. Everything since has been sampler optimisation, benchmarked against the Stan implementations it replaced.
◆ Where it's heading
The feed reads as one architectural bet followed by the work to justify it. After the native backend landed, the releases are a steady march of gradient and adaptation work — hand-coded gradients for more model families, L-BFGS mass matrix adaptation, an O2 build — each measured as a speed multiple against Stan. Coverage is tracked openly as a fraction (48 of 60 hand-coded configs), and unresolved problems are named rather than buried, including a deferred GP spatial bug.
◆ Prediction
The hand-coded gradient coverage count is the visible backlog, so the next releases most likely close the remaining configs and resolve the GP spatial issue that the benchmark release explicitly deferred.
