What it does
From a short profile to a route you can start this week.
- ProfileQualification, work experience, interests, skills and town. No names.
- CareersThe top five North East careers, each with a match score, the reasons for it, typical pay, the route in for your group and a source link.
- Skills gapThe career's skills you already have and the ones you're missing.
- CoursesOnly courses that close a missing skill. Free and funded ones come first.
- Grounded advisorFollow-up questions about those results, answered by Claude and checked against our data before you see them.
How it works
Models read, code judges.
No language model decides anything about you. A deterministic engine does the ranking, and the model may only explain what the engine found.
The engine
Code judges
- Ranks careers by interest, skills and local demand, with no LLM involved.
- Works out the skills gap and the courses that close it.
- Name, gender, ethnicity, age, postcode and town never change the results.
The advisor
Models read
- Sees only the engine's results.
- A validator flags any career, course, link or £ figure that isn't in our data. A flagged answer is regenerated once.
- No closed doors: there's always a route, and it points to the National Careers Service when it's unsure.
