What Keryx does
Six moving parts that quietly turn an intake into a post you'd want to apply to.
One short form captures the role, team, comp band and non-negotiables.
Readability, bias, structure and pay-transparency signals.
Catches gendered phrasing, ableist idioms and vague seniority language in English drafts.
Prompts you to state comp, level and location so candidates self-select.
Reusable tone profiles: values, do/don't words, EO statements.
Save role intakes, export to PDF / Markdown, share via public link.
Letters that land right
Pick a letter type, we draft it in your brand voice, resolve every placeholder from the intake, and show you the finished thing before you send. No more find-and-replace panic.

Heard from hiring teams
We went from three-hour edit cycles to one draft, one check, one publish. Our applicants are visibly more varied.
Ines Kovač
Head of People, Osmos
The panicky last-minute rewrites are gone. Keryx surfaces the gaps in a draft before anyone else has to.
Rafael Duarte
Talent Ops, Corren
It's the first tool that respects our brand voice instead of flattening it into corporate soup.
