Hi. I'm Jonghyeon from South Korea.
I'm just university student who contributed Uber OSS, won Intel ISEF, made growth 500K AAU used by ~1 in 10 Korean high school students for their SOP writing tool.
Now, I'm building my startup https://t.co/56iEYFRSBC that builds AI tools that help candidates write winning resumes and get clear, data-driven feedback on why they pass or fail by job mock applications.
I launched in June 2025 with purely organic traffic from a single LinkedIn post (20,000 impressions, 300 likes). Metrics are 2,500 MAU peak, 400 sign-ups, ~500 resumes created, 1,391 agent runs, 2m30s average session.
Users span US, Canada, India, China, South Korea and roles including Founder, AI Researcher (MD, PhD), Security Researcher, ML Engineer, Staff Engineer, Principal AI Architect, Sales, Business Development, Designer.
You can use free every features. You can make your resume website like https://t.co/pRLMvNPj3R

Make this your last job search by AI Resume Builder, Job Search, Mock Apply.
We use Claude to crawl, enrich, and embedding job postings from global companies, match them to curated jobs, and cluster them into similar jobs. We are using it very effectively.
Similarly, we also use it to make AI Resumes agentic. In Mock Apply, we use it to identify and quantify high-confidence data from various source channels to increase data reliability.
I’m planning to run ads targeting global users who are actively looking for a job or considering a career move.
Which channels would you recommend testing first?
We’ve updated @refresh_cv address the areas that felt missing or inconvenient when creating resumes and using the Agent.
Here’s what’s new:
1. Multilingual resume support
https://t.co/56iEYFRSBC now supports multilingual resumes when creating and publishing resumes.
2. Custom resume sections
You can now add custom resume sections beyond the default ones.
3. Language options for Agent responses
When using the Agent, you can choose both the resume writing language and the feedback language.
4. Resume visibility options
You can now choose whether to make your resume accessible only via a shared link, or make it publicly visible within https://t.co/56iEYFRSBC.
5. Resume templates
We’ve added resume templates so you can create resumes faster based on your goal or use case.
6. New Agent features
The Agent can now help with:
- Reorganizing your resume for a career transition
= Turning work experience into achievement-focused bullet points
- Making your strengths clear within 10 seconds
- Organizing your skills for a target role
- Adapting your resume to a target country and hiring market
- Checking whether your resume is readable on job platforms
- Finding achievements that can be expressed with numbers
- Identifying missing job-related keywords
7. Improved Agent usability
When you click a prompt, you can now easily enter the data needed for that prompt, such as your activities, job posting, target role, and more.
We’ve also added a full-screen mode so you can use the Agent in a more focused environment.
8. Bug fixes
We also fixed several issues, including:
- Inconsistent block height and styling in citation displays
- Cursor and input blinking issues while writing descriptions
- Broken text rendering in feedback results
By the way, Korean company job postings may start appearing on https://t.co/56iEYFRSBC as early as this week! As always, if there are any features you’d like to see, or anything you think should be improved while using Refresh, please feel free to let me know :)
Also, if you’re from an educational institution or bootcamp and are interested in bulk purchasing Resume Agent subscriptions or mock application credits, please reach out to [email protected].
We’re building @refresh_cv (https://t.co/NO6pcv8u97), a global job platform for people who want better opportunities across borders.
At https://t.co/NO6pcv8u97, you can explore jobs from 1,000 of the world’s most well-known and competitive companies, along with the information job seekers actually need: job postings, company insights, interview details, interview reviews, salary data, and more.
We already have 500,000 job postings on the platform, and we’re working to grow that to 1 million by June. We’re also expanding our coverage to include top companies in each country.
One thing we care deeply about is search quality. Users can apply highly specific filters to find exactly what they want. For example: “Find software engineering jobs in San Francisco paying over $500K, with benefits like a 401(k) and free meals.” You can also sort by salary or popularity, and browse curated collections such as New Grad Friendly, Remote-First Startups, and 4-Day Work Week jobs.
We launched in mid-February, and we’ve already reached 5K MAU and 380K search impressions. More users are also clicking through from https://t.co/NO6pcv8u97 to company career pages every week. Most of our traffic today comes from the US, UK, Singapore, China, India, and Korea. Our mock application feature has also been used by students in the US, including USC and Houston, and in Singapore, including NTU.
We’re still early, but we’re moving fast. Our goal is to make global job discovery much easier, with better data, better tools, and eventually B2B products as well.
If you know someone who wants to join a great international company, whether they’re looking for their first job or their next move, I’d really appreciate it
if you shared https://t.co/NO6pcv8u97 with them. And if you try it and have feedback on features, data, or bugs, please feel free to reach out. We’d love to improve it.
