Selfwritten
Selfwritten is an adjective and sometimes a noun used to describe material that has been authored by the person who presents it, without the involvement of another writer. In practice, it most often refers to texts such as memoirs, essays, articles, or other works that reflect the author's own voice. The form can also appear as a compound adjective (“self-written”) or, less commonly, as a single-word noun in informal writing.
In publishing and media, self-written works are typically contrasted with co-authored works or with ghostwritten material,
Copyright and attribution for self-written material generally reside with the author, subject to applicable intellectual property
