## What is Qdrant Viewer?

Qdrant Viewer is a client app for connecting directly from your iPhone to vector databases hosted either self-hosted or on Qdrant Cloud, allowing you to inspect collections and perform semantic searches.

Key Features:

- Built-in Demo Environment:
  Immediately try vector search with approximately 30,000 MeSH (Medical Subject Headings) vectors, with no configuration required.

- Flexible Connection Settings:
  Supports connection via REST API, including authentication with api-key, Bearer tokens, and custom headers.

- Collection Information Display:
  View the number of points, segments, vector dimensions, and distance function. Alias names are prioritized if set.

- Semantic Search:
  Perform vector searches using natural language. Adjust the number of results and score threshold for each search.

- Flexible Result Display:
  Select and list any field within the payload (supports nested structures). Detailed inspection in JSON format is also available.

- 3D Visualization:
  Project search results into a three-dimensional space to visually explore the distance relationships between vectors.

- Multiple Embedding Engines:
  Supports Qdrant Built-in, OpenAI, Google, Hugging Face, Cohere, and custom APIs.

- Data Source:
  Uses MeSH (U.S. National Library of Medicine, public domain) as demo data. The embedding model is intfloat/multilingual-e5-small, licensed under the MIT License.
