Meridian turns requirements, meeting notes and specifications into mind maps, PlantUML models and decision-ready briefs — in one calm working surface. No API key required to start.
Most tools stop at a diagram. Meridian keeps the structure underneath, so the same thinking can become a use case model, a sequence, a brief or a set of measures without being retyped.
Paste a brief, a transcript or a page of user stories. Meridian reads the structure, groups the themes and opens a map you can actually edit.
Use cases, sequences and component architectures are emitted as clean PlantUML. Edit the source, see the diagram, keep the file.
Turn the same model into an executive brief, a project charter or a gap analysis with owners, measures and open questions.
Requirements, workshop notes, a specification, a ticket export. Drop it in or import a file.
Map, use cases, sequence, architecture, measures, gaps, brief or charter. Eight modes, one source.
Rename, regroup, add children, collapse noise. Every edit is local and undoable.
Export JSON, Markdown, .puml or an SVG diagram. Nothing is trapped in the tool.
We are launching a customer self-service portal for a retail bank. Goals: reduce call volume by 30%, improve NPS, cut onboarding time. Stakeholders: COO, head of digital, compliance, branch operations. Risks: fraud, legacy identity, low adoption. Phase 1 in Q1, phase 2 in Q3.
Every map is a structure, not a picture. Meridian renders the shape of the model in three dimensions so a room full of people can see the same thing at the same time — then go back to the canvas and change it.
Each library is a considered starter map — not a blank canvas. Pick your domain, get the branches a senior practitioner would have drawn, then make it yours.
For analysts, architects and consultants who need to think clearly and hand over something that stands up.
For architecture and change functions that need one version of the truth, with the controls to prove it.
Open a domain, paste a page of notes, or start from a blank map. The studio is free to try and works without a model key.
