Free, open-source, local-first developer workspace for snippets, notes, APIs and diagrams
Organize reusable code fragments in nested folders, tag them for fast filtering, and jump to anything through a keyboard-driven command palette.
Write Markdown notes, explore connections between them in a graph view, and turn notes into tasks with status, priority, due dates and links to related snippets and requests.
Save API requests, run them in sequence, pass values between steps, and inspect responses or JSON diffs without leaving the app.
Connect OpenAI, Anthropic, Gemini, DeepSeek, Mistral, xAI or OpenRouter with your own key, or use a local Ollama/LM Studio model, to edit code, reorganize notes and test APIs. An MCP server exposes the same vault to external AI agents.
Free GLM-powered assistant that turns prompts into slides, sites and code
Describe your topic and Z.ai drafts a slide deck with structured layouts, headings and visual placeholders you can refine with follow-up prompts.
Paste a brief or a bug report and it will produce code in common languages, and it can scaffold functioning web pages and small full-stack apps.
Chat, brainstorming, rewriting, translation and summarising all run through the same prompt box, with GLM Flash models keeping responses quick.
Ask a question and it can ground the answer in web sources rather than relying only on its training data, useful for current facts and comparisons.
Provides industry-leading reasoning, coding, and multimodal features, but lacks dedicated automated slide and document generators.
