Slashspace

Slashspace, formerly RabbitHoles AI, is a branching AI canvas for desktop on Mac, Windows and Linux. Instead of a single scrolling chat, chats, branches, PDFs, YouTube videos, web pages and notes sit side by side on an infinite canvas. A user can select any line of a reply and branch from it, then wire sources into a chat as context so the model reads the full source rather than a search index. It works with ChatGPT, Claude, Gemini and local models. Users can bring their own API keys for providers including OpenAI, Anthropic, Gemini, Grok, OpenRouter, Perplexity and DeepSeek, or any OpenAI compatible endpoint, and can run Claude Code, Codex and Cursor on their own subscriptions. Models can be compared side by side and switched per chat. An orchestrator mode plans work, creates and connects nodes and hands pieces to subagents. Tools such as Notion, GitHub and Gmail connect through Composio and MCP. It is aimed at researchers, students and others working on problems that do not move in a straight line. The Yearly plan is $89 per year with a 3 day free trial. A Forever lifetime plan is $249 one time and refundable within 7 days. Both include 500 wallet credits for hosted models, two device seats and the full app. One credit is worth $0.01, and models on the user's own keys or subscriptions do not use credits.
