Slashspace
Infinite-canvas desktop app for running many AI sessions side by side across providers

rabbitholes.aiAbout Slashspace
Slashspace, previously Rabbitholes AI, is a desktop app that puts AI conversations on an infinite canvas instead of in a linear thread. The problem it names is context collapse: a power user working across several models ends up copy-pasting prompts and responses between apps and chat threads, playing telephone with their own reasoning, and losing the shape of the work. On a canvas, many sessions run side by side and stay visible at once, branches spread out instead of scrolling away, and handing context from one node to another is a click rather than a re-paste. You can move freely between sessions, models and providers in one place, bringing your own subscriptions or keys from Anthropic, OpenAI and others, and pull in PDFs, web pages and YouTube as sources. Storage is local-first, and the app runs on macOS, Windows and Linux. The pricing model is unusual and worth reading carefully: every tier is bring-your-own-key, and what you pay for is device activations, canvas count, connector count and a bundle of included usage value — $2 one-time on Free, then $4, $10 and $50 per month as you move up. That means the subscription buys capability and headroom rather than inference, which stays on your own provider account.
