Korotchaim logo Korotchaim

AI job-hunting copilot โ€” match your CV to any job, tailor resumes, draft cover letters, practice interviews. Bilingual EN+HE with a grounding contract that prevents the AI from fabricating skills you don't have.

Korotchaim is an AI job-hunting copilot for tech professionals worldwide, with deep calibration for the Israeli tech market. Built around a grounding contract that prevents the AI from inventing skills, projects, or metrics that aren't in your real CV.

What it does

  • Match Analyzer โ€” paste a job description and your CV, get a 0โ€“100 match score with grounded strengths, gaps, and missing keywords. Free, no account needed.
  • Adapt Resume โ€” rewrite your resume for a specific role. Every bullet traces back to a source phrase. Gaps are flagged honestly, not fabricated.
  • Cover Letter โ€” three variants per job (story / metrics / culture-fit). Source-traceable. No invented experience.
  • Interview Simulator โ€” 8 questions tuned to the JD, real-time scoring, model answers.
  • Chrome extension โ€” runs the same flow inline on LinkedIn job pages and profile pages.

What's different

Most AI resume tools fabricate. We tested four big names with a controlled CV+JD pair: three of them added skills the candidate didn't have. Korotchaim's grounding contract is in the system prompt of every AI surface: every claim must trace to a source phrase, or it gets a gap note instead of fabrication.

Fully bilingual EN + HE with RTL. The Hebrew side is native, not translated. 20+ Israeli tech companies pre-calibrated (Wix, Monday.com, Lightricks, Nvidia Israel, Lemonade, Fiverr, Riskified, Mellanox, and more).

Pricing

Free tier is real โ€” Match Analyzer unlimited, plus 3 cover letters / month, no credit card.

Built by a backend engineer (ex-Monday.com, Wix, Lightricks) tired of watching friends send 200+ applications into the void.

    The website offers content in multiple languages including English and Hebrew, making it accessible to a broader international audience of researchers and family history enthusiasts.
  • Community-driven data
    The platform benefits from contributions by its user community, allowing for a growing and evolving database of Jewish family histories, records, and connections.

    The site provides free access to at least some of its genealogical records and resources, lowering the barrier to entry for people beginning their family history research.

React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.
  • Performance
    The component is optimized for performance, handling large data sets efficiently without significant slowdowns, which is critical for applications that manage extensive hierarchical structures.
  • Community and Documentation
    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.
