What it does

Role-specific career prep without exposing the internal prompt.

01

Resume targeting

Extracts JD signals, maps them to resume evidence, and creates a conservative ATS-friendly draft.

02

Company brief

Creates a candidate-facing research brief with likely priorities, role value, and smart interviewer questions.

03

Interview answers

Generates spoken English answers using a self-contained role prompt and prompt-only API contract.

04

Admin review

Keeps raw prompts, manifests, and test packs available internally while hiding them from normal users.

AI workflow

Designed as a product, not just a prompt demo.

Production thinking

Cost control matters before public launch.

Token cost risk

Every public generation can consume OpenRouter credits. Without controls, a free public site can create uncontrolled usage.

Recommended guardrails

Use login, per-user daily limits, per-IP throttling, CAPTCHA for suspicious bursts, workspace budgets, and server-side usage tracking.

Business model

Keep a small free sample, then require payment or invite access for expanded packs, reruns, and deeper prep.
