JACVault

JACVault is an AI-powered job application platform for the US and DACH markets. Instead of stuffing keywords into a template, it builds every application from real context: the job posting, the company, the industry, your profile and your personal writing voice.

Under the hood runs JACEngine, a proprietary orchestration engine that wraps non-deterministic LLM components in deterministic validation layers. The result is output you can check and trust, not a black box.

Key features

• Multi-source generation: tailored CVs and cover letters from job posting, company, industry, profile and personal voice
• Judge model: automated quality scoring of every generated application
• CV Studio: ATS-safe PDF rendering with a cascading design system, tested against leading ATS parsers (Textkernel, Affinda, RChilli)
• Interview preparation: company dossier plus a live interview chat simulation with different interviewer personas
• Application tracker to keep every application in one place
• Chrome extension to capture job postings directly from the browser

Privacy by design

Built in Germany with GDPR compliance as a structural principle: AI processing runs via EU-region endpoints with data processing agreements and no-training clauses.

Pricing

Your first application is free. After that, JACVault is available as a monthly subscription.
