TL;DR
Thorsten Meyer AI has published details of Threlmark, a free and open-source roadmap hub for ranking work across multiple projects. The product is described as local-first, score-based and built for AI-assisted software work, but its release status, adoption and technical limits are not clear from the source material.
Thorsten Meyer AI has published details of Threlmark, a free, local-first and open-source roadmap hub that ranks work across multiple projects and is designed to answer which task should be done next, according to source material from the site.
The source describes Threlmark as a “command deck” for projects and roadmaps. Each project has its own board, while a Portfolio view ranks items from every project together. The stated goal is to move beyond task lists that record work and boards that track status by giving users one ranked list across their full set of responsibilities.
Threlmark’s ranking system uses four inputs: impact, evidence, fit and effort. The source says impact is weighted most heavily, evidence and fit also raise the score, and effort subtracts from it. The formula shown in the material is impact x 3, evidence x 2, fit x 2, minus effort x 1.5, with the result rounded and not allowed to fall below zero.
The product is also presented as flow-aware. The source says Threlmark can show work-in-progress limits, aging and stale flags, throughput and cycle time. It also describes an AI handoff loop in which a user generates a brief, gives it to an AI coding agent such as Claude or Codex, and the card can move based on a reported done, blocked or failed status.
Why It Matters
The announcement matters because many workers now manage several products, side projects or client efforts at once, while AI coding tools can increase the rate at which new work is started. Threlmark is aimed at the bottleneck that follows: deciding what should receive attention first across the whole portfolio, not only inside one project board.
If the product works as described, its main value would be making priority decisions visible and repeatable. A scored backlog can give teams and solo builders a shared reason for why one item rises above another. Its local-first design may also appeal to users who do not want project data tied to a hosted service.

Background
The source frames Threlmark as a response to scattered planning systems: notes apps, spreadsheets and unfinished ideas held only in memory. It argues that standard to-do apps track tasks and project boards track status, but neither provides a single ranking across all active projects.
The material places Threlmark in the current wave of AI-assisted development. Rather than treating AI-generated code work as separate from planning, the product is described as linking the plan, the handoff brief and the completion report in one loop. The source also says this is part one of a series on Threlmark and IdeaClyst.

What Remains Unclear
The source material does not state a release date, version number, supported platforms, license details, repository location, pricing beyond the free and open-source claim, or whether Threlmark is already available for public download. It is also not clear how the AI reporting loop is verified, which agents are supported in practice, or how the tool handles conflicting priorities across teams.

Key Questions
What is Threlmark?
Threlmark is described by Thorsten Meyer AI as a local-first roadmap hub for ranking work across multiple projects, tracking flow and handing tasks to AI coding agents.
How does Threlmark rank tasks?
The source says users rate items on impact, evidence, fit and effort. Impact, evidence and fit raise the score, while effort lowers it.
Is Threlmark only a to-do app?
No. The source positions it as a portfolio-level planning tool, with project boards, ranked work across projects, flow signals and AI task handoff features.
Is Threlmark available now?
The source material calls it free and open source, but it does not provide enough detail to confirm availability, installation steps or supported platforms.
