Notre avis

GNO est un moteur de recherche sémantique local qui indexe des documents (PDF, markdown, code, etc.) et permet des recherches par mots-clés, par similarité vectorielle ou avec réponses générées par IA, le tout sans cloud ni clé API.

Points forts

Fonctionne entièrement en local, garantissant la confidentialité des données
Plusieurs modes de recherche (BM25, vectoriel, hybride) avec des compromis vitesse/précision
Interface web intégrée pour naviguer et rechercher visuellement
Support de collections, tags et contexte pour affiner les résultats

Limites

Nécessite une phase d'indexation initiale qui peut être longue sur de gros volumes
Les modèles d'IA locaux peuvent être moins performants que les solutions cloud
La qualité des réponses IA dépend du modèle et du contexte fourni

Quand l'utiliser

Utilisez GNO lorsque vous avez besoin de rechercher rapidement dans un grand nombre de documents locaux, d'effectuer des recherches sémantiques ou de poser des questions avec réponses sourcées.

Quand l'éviter

Évitez GNO si vos documents sont principalement sur le cloud, si vous n'avez pas besoin de recherche avancée, ou si l'indexation initiale serait trop coûteuse en temps pour des besoins ponctuels.

Exemples

Search documents semantically

Search my notes folder for documents about machine learning, using semantic search to find related concepts.

Index and ask questions

Index the ~/docs directory with GNO, then ask it to summarize the key findings from the project reports and provide citations.

Set up a knowledge base

Set up GNO to index all markdown files in my knowledge base, add relevant tags, and start the web UI so I can browse and search.

name: gno description: Search local documents, files, notes, and knowledge bases. Index directories, search with BM25/vector/hybrid, get AI answers with citations. Use when user wants to search files, find documents, query notes, look up information in local folders, index a directory, set up document search, build a knowledge base, needs RAG/semantic search, or wants to start a local web UI for their docs. allowed-tools: Bash(gno:*) Read

User wants a web UI to browse/search documents
User asks to get AI answers from their documents
User wants to tag, categorize, or filter documents

Quick Start

gno init                              # Initialize in current directory
gno collection add ~/docs --name docs # Add folder to index
gno index                             # Build index (ingest + embed)
gno search "your query"               # BM25 keyword search
