Why use an AI tool for cover letter generation?
Writing a compelling letter for every role is hard to sustain, especially when juggling multiple applications. AI accelerates the process by parsing job descriptions, aligning your experience to requirements, and generating role-specific drafts that respect tone and formatting. Because some tools use advanced language models with strong grammar and style control, the first draft is often close to final. Others add ATS-aware keyword targeting and integrations to LinkedIn, Google Drive, or ATS portals, which means fewer manual edits and copy-paste errors. A subset also offers browser autofill or auto-apply to remove friction at submission time. Taken together, these capabilities reduce repetitive work, improve consistency, and increase the odds your application clears initial screens.
