Cover letter generator
A letter that cannot outrun your resume
Paste a resume and the posting. Hallstamp drafts a one-page letter from backed overlap only, names the receipts it used, and leaves unsupported requirements out.
Resume first
The tool reads the resume as the proof source. If a skill or credential is not present there, it cannot become a claim in the letter.
Posting second
The posting decides what overlap matters. A full posting gives the generator enough context to avoid a generic letter.
Receipts visible
Every named skill in the draft has a source line from the resume. Missing skills appear as gaps, not as invented confidence.
Export only when clean
The validator checks length, source quality, banned claims, unsupported gaps, and plain punctuation before copy or download is available.
