Building LoopStack Recruit — An AI-Powered Toolkit for Recruitment Professionals

Recruiters spend a disproportionate amount of their time on admin. Writing job descriptions, screening CVs, crafting candidate outreach messages, preparing interview questions — the work that fills a recruiter's day is mostly text generation and pattern matching. It's exactly the kind of work that AI handles well, but most recruitment tools only address one piece of the puzzle.

This is the story of LoopStack Recruit, an AI-powered recruitment toolkit we built from scratch. It bundles six tools into one platform — JD writer, candidate outreach, CV screener, interview questions, client pitch generator, and psychometric tests — with a simple subscription model and a free tier that requires no credit card.

The Problem: Too Many Tools, Too Much Admin

Agency recruiters and in-house talent teams use a patchwork of tools to get through their day: an ATS for candidate tracking, LinkedIn for sourcing, Word or Google Docs for writing job descriptions, email for outreach, and various sites for interview question ideas. None of these tools are designed to work together, and the recruiter ends up copying and pasting between them constantly.

The AI piece is especially fragmented. There are standalone CV screeners, job description generators, and interview question banks — but they're all separate subscriptions, separate logins, separate workflows. We saw an opportunity to bundle everything into a single, simple platform.

The Six Tools

LoopStack Recruit includes six AI-powered tools, each designed to replace a specific manual task in a recruiter's workflow:

• JD Writer — Generates inclusive, SEO-optimised job descriptions from minimal input. Role title, seniority level, and a few key requirements are enough to produce a complete, branded JD.
• Candidate Outreach — Creates personalised LinkedIn and email messages aimed at higher response rates. Adjusts tone and length based on the role and candidate seniority.
• CV Screener — Compares a CV against a job description and returns a fit score with strengths, gaps, and an interview recommendation. Saves 10-15 minutes per CV review.
• Interview Questions — Produces competency-based question banks by role and seniority level. Includes behavioural, technical, and situational questions.
• Client Pitch Generator — Builds tailored pitch documents to win recruitment mandates. Input the client's industry, role requirements, and your agency's differentiators — get a polished pitch document in seconds.
• Psychometric Tests — Generates SHL-style scenarios, situational judgement tests, and aptitude assessments on demand. Useful for filtering candidates before first-round interviews.

The Architecture

Like TenurAI, LoopStack Recruit is built on a React frontend with a Node.js API backend. The AI layer handles text generation across all six tools, with prompt engineering tailored to each use case — a job description prompt is structured very differently from a psychometric test prompt.

The platform is deployed at app.loopstack.co.uk, separate from the marketing site, with CloudFlare handling CDN and security. User accounts, generation history, and profile data are stored in PostgreSQL.

Pricing & Go-To-Market

We designed the pricing to remove every possible barrier to trying the product:

• Free Trial — £0. 10 total AI generations with no expiry. All six tools, full output quality, no credit card required.
• Pro — £19.95/month, cancel anytime. Unlimited generations, all tools, profile auto-fill, email/LinkedIn send actions, priority support.
• Enterprise — Custom pricing. Multi-seat, custom onboarding, dedicated account manager, volume discounts.

The 10 free generations never expire — removing urgency anxiety and letting users evaluate the product at their own pace. The Pro price of £19.95 is deliberately lower than a single ChatGPT subscription, making it an easy "justify on expenses" purchase for individual recruiters.

Key Design Decisions

1. Simplicity over features

We deliberately kept the interface minimal. Each tool does one thing well — input a few details, get AI output, copy or send. There's no dashboard clutter, no reporting module, no calendar integration. The goal was to be the tool that recruiters actually use, not the platform that tries to replace their entire workflow.

2. Free tier with no expiry

The 10 generations never expire. This was a deliberate decision to build trust — a recruiter can try the tool once a week for ten weeks and still have generations left. It converts the "I'll try it later" sceptics into actual users who eventually hit the limit and upgrade.

3. Prompt engineering per tool, not one-size-fits-all

Each of the six tools has a dedicated prompt structure optimised for its specific output. The JD writer prompt focuses on inclusivity and SEO keywords. The CV screener prompt emphasises structured analysis against specific criteria. The psychometric test generator uses a completely different prompt architecture to produce consistent, test-like scenarios.

What We Learned

Price sensitivity in recruitment is high. Individual recruiters often pay for their own tools. At £19.95/month, LoopStack Recruit is priced to be an individual decision — no procurement process, no manager approval.

The free tier drives qualified leads. By requiring no credit card, we removed the single biggest barrier to trial. Users who exhaust their 10 free generations are highly qualified — they've already experienced the value and are choosing to upgrade.

Market at the pain point, not the technology. Lead with "spend less time writing JDs" rather than "GPT-4 powered text generation." Recruiters care about outcomes, not architecture.
