1NX is a free, local-first infinite canvas for flowcharts, wireframes, mind maps, documents, code, and images, with editable imports and on-device processing.
1NX is a local-first infinite canvas for turning ideas into flowcharts, wireframes, mind maps, process plans, documents, code blocks, and image-based deliverables. It opens directly to an editable canvas without requiring registration or a template selection.
The product builds on a familiar hand-drawn whiteboard workflow while adding structured diagramming, document previews, editable file imports, local image tools, AI-assisted generation, and multiple export formats.
According to the official 1NX feature documentation, content and processing stay on the user's device. The public canvas can be opened without an account, and local files can be arranged and edited without uploading them to cloud storage first.
For larger projects, 1NX publishes a 10,000-element browser benchmark and describes performance regressions as release-blocking. Its feature page reports a 9.5 ms p95 frame time while dragging 10,000 on-screen elements in the referenced test environment.
1NX can generate editable flowcharts, mind maps, pages, and presentations from a prompt. Because results remain canvas elements, users can revise labels, layouts, colors, connectors, and supporting material instead of receiving only a flat image.
Image enhancement and background removal are also described as on-device features, which can be useful when a planning board includes screenshots, product mockups, diagrams, or presentation assets.
During the editorial review on August 26, 2026, the public 1NX canvas opened without registration and the official site did not present a paid pricing plan. Toolsfine therefore lists 1NX as Free.
No. The official feature page says the canvas opens without registration or a template picker.
Supported editable imports described by 1NX include Mermaid, PlantUML, draw.io, Visio, XMind, OPML, and Excalidraw.
1NX describes its main workflow as local-first and says files, processing, and results stay on the user's device.
