Build a universe of ideas.
A character leads to a place. A place leads to a conflict. A small note becomes the beginning of an entire project. Opus gives those connections room to grow.
Made for writers, worldbuilders, designers, researchers, and people who think in connections, Opus combines visual mapping, linked reference pages, media, and guided presentations in one desktop workspace.
See the connections in 3D
Orbit, pan, and zoom through constellations of ideas, or use a fixed 2D view. Organize with branches, categories, colors, free nodes, search, and a linked outline. Customize labels, lines, spacing, and arrangements.
Bring separate worlds together
Opus Space brings selected constellations into one universe. Keep projects independently saved, connect them, and move between the big picture and the details.
Turn your map into a wiki
Generate linked reference pages from the titles, notes, categories, and attachments already in your constellation. Local templates organize information you supplied. Your original map stays intact.
Put the details where they belong
Attach text, images, GIFs, and supported local audio or video to an idea. Use Story Play to present selected ideas and their content in a sequence you control.
Keep your work close
Core mind mapping, writing, wiki editing, and Story Play work offline without an Opus account. Save local project files, keep backups, and export portable Opus files, JSON, PDF outlines, or wiki folders and ZIPs.
Bring existing work with you
Import compatible EMMX maps, FreeMind and OPML outlines, CSV/TSV, structured text, Markdown, and HTML headings and lists. Import support depends on the source format and content; third-party layouts and features may not transfer exactly.
Explore together
The live-collaboration preview supports temporary editor or viewer sessions with up to eight participants, including the host. The host keeps Opus open. Internet sessions require a connection and use a temporary relay. Persistent shared workspaces, automatic reconnection, and offline merging are not currently included.

A few things you might ask.
Is this a subscription?
No paid plan or subscription is being offered through this website yet. The exact price, payment model, and license scope will be disclosed on the product listing before checkout. Sending a launch inquiry does not create a subscription.
Does my writing get sent to Intepra?
Ordinary local use does not send your constellations, notes, attachments, wikis, or backups to Intepra. Network features, storefront transactions, and anything you choose to send to support are covered in our privacy policy.
Can I use it without internet?
Yes. Core mind mapping, wiki editing, and Story Play are local tools. Internet collaboration and GitHub repository imports need a connection.
Where can I get help?
Email quadiermackey@gmail.com with your Opus version, operating-system version, and a description of the issue. Our initial reply target is five business days.
