Do Frase and Semrush do the same thing?

Not exactly — Frase is categorized as content research and optimization tool, while Semrush is all-in-one SEO & marketing platform. They overlap enough to be compared, but they're not interchangeable.

Can I use Frase and Semrush together?

Usually, yes — most tools in this space are complementary rather than mutually exclusive, since they cover different parts of the content workflow. Whether it's worth paying for both depends on whether the overlap in what they do is small enough to justify it.

Which is better for building topical authority — full coverage of a subject, not just individual pieces?

Neither Frase nor Semrush plans a full topical map or hosts the result — that's a different job than either is built for. Omnitopical plans the complete page set a topic needs, writes every page, interlinks them automatically, and hosts the result on your domain for a flat $99/mo.
