1NX

What is 1NX?

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.

Key features

• Infinite canvas: Organize sketches, formal flowcharts, UI wireframes, mind maps, tables, and swimlanes in one workspace.
• Editable imports: Convert Mermaid, PlantUML, draw.io, Visio, XMind, OPML, and Excalidraw files into elements that can still be moved and edited.
• Documents and code: View PDF, DOCX, PPTX, XLSX, Markdown, text, and highlighted code directly on the canvas.
• Local image tools: Crop, slice, mosaic, erase, create collages, enhance image resolution, and remove backgrounds on-device.
• Flexible delivery: Export work as PNG, SVG, PDF, web pages, or editable PPTX files.

Local-first workflow

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.

AI, diagrams, and image work in one place

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.

Pricing

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.
