Job-search copilot
Lock in the job. One profile, a résumé tailored to every role.
Most tools make you rewrite your résumé for every posting, or spray one generic copy everywhere. lockdin imports your background once and writes a genuinely tailored, truthful résumé for each job — that you review and send.

Your master profile

Tailored · Backend Engineer (ETL)
- Built a Python ingestion pipeline in PostgreSQL processing 2M events/day — cut report latency from hours to minutes
- Designed and shipped a REST API consumed by 3 internal services, owned end to end
- TA experience moved below the fold — real, but not what this role hires for.
Written for the job, not the job market.
The lockdin principle
Five templates, one engine
The résumé, set properly.
Real embedded typography, a guaranteed single page, and layouts a screening parser reads cleanly. Switch templates any time — your content re-renders instantly.
Previews rendered by the same engine that makes your PDF — sample content
House rules
Built to be trusted with your name on it.
Nothing invented
The tailor draws only on facts from your profile. Real numbers stay; missing ones are never made up — a bullet gets dropped before a metric gets faked.
No auto-apply
Recruiters are drowning in one-click spam and platforms are banning it. lockdin prepares the strongest truthful application; you hit send.
Read like a screener reads it
Most Fortune 500 résumés are parsed by software before a human looks. We extract the text back out of every template the same way and verify nothing breaks.
The desk
