gleek.io turns text into flowcharts, UML, and ER diagrams without a mouse, with a free plan and Premium plans from €6.95/month.
gleek.io is a diagramming tool built around a text-based, keyboard-first workflow: instead of dragging and connecting shapes with a mouse, users type structured descriptions that gleek.io renders into flowcharts, UML diagrams, entity-relationship diagrams, Gantt charts, and other diagram types.
The product is made by Blocshop, a software development company founded in 2012 and headquartered in Prague, Czech Republic, with additional offices in Brno and Tbilisi.
Because diagrams are stored as text rather than binary files, they work naturally with version control systems, avoiding the merge conflicts and diffing problems common with drag-and-drop diagramming tools. gleek.io supports flowcharts, ER diagrams (with Chen or Crow's foot notation), UML class, sequence, state, and object diagrams, Gantt charts, and user journey diagrams.
The tool also includes real-time collaboration for teams, a library of pre-built templates, multiple export formats, and an AI chat feature on paid plans that can generate diagrams directly from natural-language prompts.
gleek.io offers a Free plan that supports up to 5 diagram files with a 40-object limit per diagram; diagrams on the Free plan are stored locally in the browser and can only be exported as PNG, and the interface displays ads.
Paid plans remove ads and unlock the AI chat feature: Premium Monthly and the Team plan cost €6.95 per month, while a Premium Per-Activity plan costs €10.99 per month but only bills for months in which the tool is actually used, pausing charges during inactive months.
