An autobiographist is someone who writes an account of their own life. There are several synonyms that could be used to describe this kind of writer, such as autobiographer, memoirist, chronicler, or biographer of oneself. These terms all convey someone who is actively constructing a narrative about their own experiences and presenting it to others. Other related synonyms might include diarist, journal-keeper, or personal historian, which all suggest a more private or self-reflective approach to recording one's life. Whatever the specific synonym, the primary focus of an autobiographist remains the same - to tell their own story in their own words.
