How Vector Embeddings Work

Text embeddings transform words and sentences into coordinate points in a multidimensional mathematical space. Sentences with similar contextual meaning produce vector embeddings that are located closer together.

Cosine Similarity

Measures the cosine angle between two vectors, regardless of document length. Ideal for search relevance.

Euclidean Distance

Calculates the direct straight-line distance between two points in vector space.

Manhattan Distance

Measures distance along grid axes (L1 norm), useful for sparse vector comparisons.

How to Generate Text Embeddings Online

  1. 1

    Select Mode

    Choose between Single Generation for vector exploration or Compare & Analyze for pairwise similarity scoring.

  2. 2

    Configure Dimensions

    Select 768D (lightweight), 1536D (standard OpenAI text-embedding-3-small dimension), or 2048D (dense).

  3. 3

    Input Text

    Enter your sentences, queries, or document excerpts into the input field.

  4. 4

    Generate & Inspect

    View raw vector coordinates, magnitude, and visual similarity charts in real time.

  5. 5

    Export JSON

    Download the raw vector arrays to ingest into vector databases like Pinecone, Qdrant, Weaviate, or pgvector.

Common Use Cases

Retrieval-Augmented Generation (RAG)

Inspect embedding distances between user prompts and knowledge base chunks to optimize chunk size and search thresholds.

Semantic Search Prototyping

Test how well query variations map to target documents without standing up an entire cloud vector database.

Deduplication & Plagiarism Checks

Evaluate paraphrase similarity scores to identify duplicate support tickets or similar academic submissions.

Zero-Cost Machine Learning Learning

Learn vector mathematics and transformer embeddings interactively without incurring API costs.

🔒 Privacy & Local Processing Guarantee

Your inputs remain strictly confidential. Calculations execute directly inside your browser using client-side algorithms. No text, prompts, or vectors are uploaded or stored on any external server.

Frequently Asked Questions

Do I need an OpenAI API key to use this embedding tool?

No. This tool runs entirely free in your browser without requiring any API keys, tokens, or payment details.

Which vector dimensions are supported?

You can choose between 768, 1536, and 2048 dimensions to match popular open-source and commercial embedding models.

Can I export vectors for use in Pinecone or pgvector?

Yes. Click the Export JSON button to download standardized float arrays formatted for immediate ingestion into any vector database.

How is Cosine Similarity calculated?

Cosine similarity evaluates the cosine of the angle between two multi-dimensional vectors, producing a normalized score between -1 and 1 (or 0% to 100%).
