Embedding Similarity Explorer

This tool works on numbers you paste. It does not create embeddings and does not call any embedding service.

How to use this tool

  1. Paste the first vector of numbers.
  2. Paste a second vector of the same length.
  3. Press Generate for the cosine similarity: 1 means the same direction, 0 means unrelated, -1 means opposite.

Worked example

For the vectors [1, 2, 3] and [1, 2, 3], the cosine similarity is 1, because the two vectors point in exactly the same direction. For [1, 0] and [0, 1] it is 0.

What this tool does not do / Limits

This tool computes cosine similarity from numbers you paste only. It does NOT create embeddings, does not call any model or API, and cannot turn text into vectors for you.

Frequently asked questions

Why must both vectors have the same length?

Cosine similarity compares matching positions one by one, so vectors of different lengths cannot be compared this way.

What does a score near 0 mean?

It means the vectors point in unrelated directions. It does not by itself prove two texts are unrelated, since the result depends on the numbers supplied.
