Features and specs

What each product offers, as listed by its team.

Hello Recruiter 12 features
Nullstack 5 features
  • AI HR Screening Interviews (ARIA)
    ARIA conducts live, adaptive two-way screening interviews with every candidate automatically. No scheduling. No back and forth. ARIA covers culture fit, salary expectations, availability, experience depth, and soft skills, asking follow-up questions based on what the candidate actually says. Average interview duration: 45 minutes. Candidates are always informed they are speaking with AI.
  • Consistent Criteria-Based Scoring
    Every candidate is scored against criteria the employer defines. Three parts: must-haves (work authorisation, salary range, location), role-specific criteria match, and skill strength. The score is consistent every time and comes with evidence and reasoning pulled from both the resume and the interview. No black box. No mystery numbers.
  • Progressive Intelligence
    Candidate scores update automatically after every interview round based on what the candidate actually demonstrates, not just what they claimed on their resume. If a candidate overstates a skill, ARIA catches it and the score adjusts before the recruiter sees them.
  • Bad Actor Detection and Risk Summary
    25+ fraud signals run across every candidate simultaneously. 13+ resume checks including hidden text, keyword stuffing, credential gaps, and AI-written content detection. Video analysis covers lip sync mismatch, second voice detection, camera-off percentage, and keyboard activity patterns. ARIA cross-questions candidates to detect AI-assisted responses. All flags load in a Risk Summary before the candidate reaches the recruiter. Informational only. Never auto-rejects.
  • AI Coding Interviews (MAX)
    MAX conducts live technical assessments with a real IDE, real-time evaluation, syntax highlighting, and AI-powered scoring. Evaluates not just whether the candidate got the answer right but how they think, problem-solve, and collaborate.
  • AI Proctored Vibe Coding
    An industry-first capability. Combines AI proctoring with live coding assessments to evaluate a candidate's problem-solving approach, coding style, thought process, and collaboration patterns, not just the output.
  • Resume Parsing and Candidate Enrichment
    Detailed structured extraction from every resume. Calculates years of experience, estimates salary progression, highlights skills and gaps. AI-generated candidate summaries focus on impactful work and relevant skills, excluding name, age, gender, and protected attributes to reduce bias.
  • AI Knowledge Base
    Companies feed Hello Recruiter their company overview, culture, products, tech stack, interview topics, benefits, and policies. ARIA uses this to interview candidates like an insider, not a stranger reading a generic script.
  • Candidate Magic Link and Portal
    Every candidate gets a self-serve portal to track their application status in real time. No black hole applications. Builds employer brand and improves candidate experience.
  • Take-Home Assignment Automation
    AI generates the assignment, sends it to the candidate, evaluates the submission, and scores it automatically. No manual creation, distribution, or review required.
  • Integrated Candidate Communications
    Email conversations and internal comments managed within the platform. Templates and basic messaging for recruiter-candidate communication.
  • Interview Hub
    Tracks all scheduled, completed, cancelled, and expired interviews in one place. Supports interview link extensions for candidate timing flexibility.
  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Hello Recruiter and Nullstack.

What makes your product unique?

Hello Recruiter's answer

Hello Recruiter is the only hiring platform that conducts live, adaptive, two-way AI screening interviews. Not forms. Not chatbots. Not pre-recorded video. The AI adapts to every candidate's answer in real time, asks follow-up questions, and produces a scored, evidenced shortlist that the recruiter uses to make the final call.

Built specifically for small and medium businesses that are always hiring. Live in minutes. No complex implementation required. Per-organisation pricing means the whole team is on board from day one.

In two years: 1.5M+ candidates screened, 25,000+ fraudulent applicants caught, average time to hire cut from 44 days to 11 days.

Why should a person choose your product over its competitors?

Hello Recruiter's answer

Every candidate gets interviewed, not just the ones whose resume made it past a keyword filter.

Scores come with reasoning and evidence. Recruiters can explain every hiring decision, which matters for compliance in US and European markets.

Fraud detection runs automatically across every candidate. AI-written resumes, impersonation, deepfakes, and AI-assisted responses caught before they waste recruiter time.

Per-organisation pricing replaces recruiting agency fees of $9,000 to $15,000 per hire. Ten hires a year on the Scale plan at $99 per month saves $80,000 to $140,000 annually.

Live in minutes. No complex implementation. No dedicated IT team required.
