Grape is a desktop note-taking app that pairs a rich block editor with AI capabilities. You bring your own API keys from providers like OpenAI, Anthropic, Google, Groq, or DeepSeek, and the AI can create, update, search, and organize your notes through a chat interface. Notes are indexed with vector embeddings for semantic search, so you find content by meaning rather than exact words. Built-in study tools generate flashcards and adaptive quizzes from your notes. Your data stays on your machine, and a one-time purchase gives you lifetime access with no subscriptions.

• AI Chat Assistant: Talk to an AI that can create, update, delete, move, and search your notes. Ask it to organize folders, find old notes, or restructure your workspace.
• Semantic Search: Notes are automatically indexed with vector embeddings, letting you search by meaning instead of exact keywords.
• Voice Memos & Transcription: Record voice memos directly in notes with real-time speech-to-text. Drag and drop audio files for instant AI transcription.
• AI Flashcards & Quizzes: Generate flashcards from any note and create adaptive quizzes that adjust difficulty to your knowledge level.
• Mind Map Generation: Auto-generate mind maps from your notes to visualize connections between ideas at a glance.
• Rich Block Editor: Tables, checklists, code blocks, images, links, and slash commands. Includes an infinite canvas for sketching diagrams and wireframes.
• Multi-Provider AI Support: Works with OpenAI, Anthropic, Google, Groq, DeepSeek, and more. Bring your own API keys.
• PDF Support & Export: Upload and navigate PDFs inside notes. Export your work as Markdown, HTML, or PDF.

• Strong Privacy with Local-First Storage: Your notes remain on your device by default, which gives you full control over where your data resides. Cloud synchronization is an optional feature rather than a requirement.
• Flexible AI Provider Choice: Connect to multiple AI providers using your own API keys, so you pick the model that fits your needs and budget.
• Powerful Semantic Search: Find notes based on their meaning instead of relying on keywords. This feature makes it easy to retrieve ideas even if you forget the exact phrasing you used.
• Built-in Learning Tools: Flashcards, quizzes, and mind maps help transform raw notes into structured knowledge for effective studying or review.
• Fast Capture and Organization Workflow: Voice notes, rich editor tools, and AI-assisted organization reduce friction when you are capturing ideas and structuring them for later use.

• No Mobile Apps: Currently available only on macOS and Windows. There are no iOS, Android, or Linux apps, limiting on-the-go access.
• Limited Collaboration Features: The application is designed primarily for personal use. It does not include features for real-time team editing or shared workspaces.

• Student Exam Prep: Take lecture notes in the block editor, then have the AI generate flashcards and adaptive quizzes from those notes. Study and test yourself without switching apps.
• Research Knowledge Management: Collect research findings across multiple notes, then use semantic search to surface related insights by meaning, even when you can't remember the exact terminology you used.
• Voice-First Note Capture: Record voice memos during meetings or brainstorming sessions and get instant AI transcriptions. Keep audio and text together in the same note.
• Personal Knowledge Base: Build a private, local repository of ideas, references, and project notes. Use AI chat to quickly find and reorganize content as your knowledge base grows.
• Visual Thinking & Planning: Sketch wireframes, diagrams, and concept maps on the infinite canvas. Auto-generate mind maps to see how your ideas connect across different notes.
• PDF Annotation & Review: Upload academic papers or documents, navigate pages inside the app, and add notes alongside the original content for streamlined review.
