Paste your title and abstract. This finds recent papers on the same topic and shows which journals actually publish that work, with their access model, indexing, and fees, so you have a real shortlist to research.
These are journals that publish work similar to yours, ranked by how many close matches each one published. That is a shortlist to investigate, not a prediction of acceptance and not a legitimacy verdict.
