Hippo
The Memory That Never Forgets
Hippo is a local-first file organizer that indexes your files and enables natural language search. All processing happens on your device using vector embeddings and semantic search. The platform can index 100K+ files and search them instantly. During our design phase (September-December 2025), we designed the local-first architecture, planned vector embedding strategy with quantized models, created incremental indexing system, and built prototype tests showing 50K files indexed in 8 minutes with <100ms search latency.
How Hippo Works
Hippo indexes your files locally, creates vector embeddings for semantic search, processes everything on your device, and optionally syncs encrypted across devices.
Install Hippo
Download and install Hippo on your device (Windows, macOS, Linux). Native app built with Tauri for performance and privacy.
Choose Folders
Select folders to index. Hippo scans files, extracts metadata, and creates searchable index. All processing happens on your device.
Background Indexing
Hippo indexes files in the background. Incremental updates only process new/changed files. Index 100K files in ~10 minutes.
Semantic Search
Search using natural language: "privacy policy from 2024" or "photos from vacation". Vector embeddings understand meaning, not just keywords.
AI-Powered Features
AI analyzes files, suggests tags, generates summaries, and answers questions about your files. All AI processing is local using Ollama.
Sync Across Devices
Optionally sync your index across devices using encrypted cloud backup. All data encrypted end-to-end. You control the keys.
Use Cases
Personal File Organization
Organize personal files, photos, documents. Find anything instantly with natural language search. Never lose a file again.
Development Projects
Index code repositories, documentation, and project files. Semantic search finds code by meaning, not just text matching.
Research & Documentation
Organize research papers, notes, and documentation. AI-powered summaries and tagging help you find relevant information quickly.
Team Collaboration
Shared workspaces for teams. Collaborative tagging, shared indexes, and team-wide search. Perfect for organizations.
