Preturnio (https://preturnio.com) - a full-text search engine for Bitcoin. With Preturnio you can search for text inside every OP_RETURN, Coinbase transaction and ordinal transaction since the genesis block (block 0).
Block explorers can search for transactions, blocks and addresses but searching for arbitrary text is a challenge. Data is stored in the blockchain natively in hexadecimal format and not easily readable by humans. Preturnio solves this with an easy-to-use search interface. Just enter the text you’re looking for and Preturnio will return highlighted results found in any OP_RETURN, Coinbase or Ordinal transaction. See when the data was created, which block it was confirmed in and other relevant details.
