JobAgent

Reads your resume and the job posting together and shows you what a recruiter will see. Free, no sign-up, no card.

A Korean 경력기술서 and an English job description are treated as a single problem, not two documents to translate. Every requirement in the posting is judged against the line in the resume that proves it, and rewrites are cited to what you actually wrote. When a number is missing, JobAgent asks you for it instead of inventing one.

Live
  • Requirement-by-requirement match against the posting
  • ATS readability check on the document as submitted
  • Line-level rewrites, each tied to the line it came from
  • Korean resume ↔ English posting, matched by concept not translation
  • Numbers are never fabricated — gaps come back as questions
  • No sign-up, no card — resume goes to the model for analysis, never to our servers

02B2B · Funding eligibility

startup-tips

Tells a company which government funding programmes — Korean and overseas — it can actually apply for, and what it would take to unlock the rest.

Country portals answer “what exists here.” startup-tips answers “can we apply, and if not, why not.” It judges a company against each programme's own published text, marks every requirement eligible, conditional or blocked, and cites the line it read. The verdict comes from rules run against the announcement data; the model only explains it. Requirements the announcement never states are marked as needing confirmation rather than guessed at.

Live
  • Korea, the US, the EU, Japan and the UK — domestic and overseas in one place
  • Eligibility judged per programme: eligible, conditional, or blocked
  • Every verdict cited back to the announcement text
  • Unlock conditions — local entity, eligible partner, minimum consortium size
  • Collected straight from official government portals and public APIs
  • Search by country, deadline or administering body
  • No sign-up — your company details stay in your browser

Read Me나를 읽다

A 16-type personality test and your birth chart — saju, the East Asian Four Pillars system, not the Western zodiac — read together, including where the two disagree.

Most personality tools hand you one frame and stop. Read Me runs a 16-type personality test alongside your birth chart — saju, the East Asian Four Pillars system, built from the date and hour you were born — then reports the points where the two results agree and the points where they contradict each other. The contradictions are the part the report spends the most words on.

Live
  • 16-type personality test, about five minutes
  • Birth chart built from your birth date and hour
  • Agreement and conflict mapped between the two readings
  • Detailed AI report delivered 1–3 minutes after payment
  • No account, no email, no ads, no subscription

ripple리플

Write one sentence about your shop and a budget; it picks local creators, splits the money, and pays them only after the post is verified. Korean only.

Most Instagram advertising for a local shop ends at “the post went up,” which leaves nothing to decide the next campaign on. Ripple starts there instead. Every creator gets their own coupon code and tracking link, so redemptions and clicks land in a report. The money sits with a payment gateway until the content passes review and the post is confirmed live, and it is held back if the post comes down inside 30 days. Ads that lack the disclosure Korea's fair-trade guidelines require are rejected at review, because the fine falls on the advertiser.

LivePilot — creators are being signed up district by district, starting with Seongsu and Konkuk
  • One sentence in, a budget split across 3–8 local creators
  • A coupon code and tracking link per creator, counted in the report
  • Funds held by a payment gateway until the post is verified
  • Settlement withheld if the post comes down inside 30 days
  • Ad disclosure checked against the fair-trade guidelines at review
  • No fee to creators — only the statutory 3.3% withholding, paid D+3

About

Two people, 4 products, no clients.

Park & Koh Works is a product studio, not an agency. We don’t take briefs and we don’t build other people’s roadmaps. Everything on this site is something we decided to make, shipped under our own name, and still operate. That is also why none of them needs an account before it will work for you: with no client roadmap in front of yours, there is nothing to collect you for.

The pattern repeats: someone hits a problem that should already be solved — a personality test that only tells you one thing, a funding portal that lists programmes without saying whether you qualify, a resume you cannot see the way a recruiter will. We build the version that answers the actual question, put it online, and find out whether we were right.

Most of what we build leans on AI, because for these problems it is the fastest route to a useful answer. None of it is AI for its own sake.

01Notice
A problem one of us actually has, or watched someone else grind through. Never a market we read about.
02Build
Smallest thing that answers the question honestly. Weeks, not quarters.
03Ship
Public domain, real users, no waitlist. The product has to survive contact.
04Watch
Where people stop, what they retry, what they never touch. That is the roadmap.

Principles

How we decide what to build, and what not to.

  • 01

    Ship it, then find out

    A product in front of a real user teaches us more in a week than a quarter of planning does. We put the first working version in public early and let the response redirect us.

  • 02

    The model is a component, not the product

    AI is the fastest way we know to solve certain problems, and the wrong tool for plenty of others. Every product here has rules, data and judgement around the model — the model alone was never the answer.

  • 03

    Say what the answer is based on

    Our products cite the announcement they read, the resume line they judged, the two readings that disagreed. An answer you cannot trace is an answer you cannot act on.

  • 04

    Ask for as little as possible

    No forced accounts, no dark-pattern subscriptions, no collecting data because it might be useful later. Most of what we build works before you have told us who you are.

  • 05

    Build for whoever has the problem

    Our problems started in Korea; they were never only Korean. We build in Korean and English from the first commit and let the product go where the problem is.

  • 06

    Small on purpose

    Two people, no outside money, no client work. It keeps the distance between noticing a problem and shipping something for it measured in weeks.

Building next

More things are
being built.

There is always a next one in progress. We announce products when they are live and usable, not before — so this page stays a list of things that exist rather than things we intend.

We don’t take briefs, but we do read every message. Tell us what is broken in one of these, ask to hear when the next one ships, or tell us what you’re building — a real person answers.
