TL;DR
Thorsten Meyer AI has introduced Threlmark, a free, open-source roadmap hub designed to rank the most valuable next task across multiple projects. The product is presented as a local-first alternative to task lists and boards, with scoring, flow signals and an AI handoff loop.
Thorsten Meyer AI has introduced Threlmark, a free and open-source roadmap hub that aims to answer which task is most valuable to do next across all of a user’s projects, a problem the company says ordinary to-do apps and project boards do not solve.
According to Thorsten Meyer AI, Threlmark is built around a cross-project Portfolio view that ranks work from every project together. The company says each item receives a priority score based on four 1-to-5 inputs: impact, evidence, fit and effort. Impact is weighted heaviest, while effort subtracts from the score.
The product also adds flow signals that go beyond a standard task board. Thorsten Meyer AI says Threlmark can show work-in-progress limits, aging items, stale flags, throughput and cycle time, with in-progress items and blockers receiving added weight in ranking.
Threlmark is also described as built for AI-assisted software work. The source material says users can generate a brief for an AI agent such as Claude or Codex, hand off the task, and have the agent report whether the work is done, blocked or failed. A successful report can move the card to Done, according to Thorsten Meyer AI.
Why It Matters
The announcement matters because many builders, founders and solo operators now manage several projects at once while also using AI coding assistants to move work forward. Threlmark is positioned as a tool for deciding what work deserves attention first, rather than only recording what work exists.
If the product works as described, it could reduce one common failure mode in multi-project work: starting too much while finishing too little. Its ranking model gives users a visible way to compare tasks across separate projects, while its flow metrics focus attention on work that is stuck or close to completion.

Background
The source material frames Threlmark as a response to plans being split across notes apps, spreadsheets and memory. Thorsten Meyer AI argues that to-do apps track tasks and project boards track status, but neither gives one ranked answer across everything a person is building.
Threlmark is described as local-first, meaning data runs on the user’s computer as plain, readable files. The company says the product requires no account, cloud service or subscription lock-in. The material also identifies Threlmark as part of a series on Threlmark and IdeaClyst.
