blank Overview

blank, known online as @blankwebdev, is the founder of AITDK and a former Tencent employee whose public profile now describes freelance work.^[1][2] The same profile lists AITDK, SubmitDirs and Traffic.cv as ongoing products.^[1] Together, these products address website analysis, directory distribution and traffic research, giving the portfolio a consistent focus on the practical work of operating websites.^[3][4][5]

What blank Built

AITDK combines free AI generators and rewriters with a browser extension for website research.^[6] The extension brings traffic estimates, backlinks, on-page SEO checks, headings, structured data and domain information into one panel.^[3] Its current website also describes a GEO score intended to assess a page's readiness for AI search.^[3]

SubmitDirs began as a directory-submission service after blank reported dissatisfaction with services that included low-quality destinations.^[4] The launch offer described manual submissions to 105 directories and a detailed completion report.^[4] In a separate update, blank said the Mkdirs template was used to add a directory to SubmitDirs itself.^[7]

Traffic.cv provides website traffic research through individual-domain, bulk, keyword and domain-extension searches.^[8] Its launch announcement credited Gefei's approach of moving between websites and keywords as inspiration, and explicitly highlighted mobile usability.^[8] The current site adds monthly leaderboards covering new, growing and highly visited websites, alongside revenue-oriented discovery boards.^[5]

How blank Builds

blank has documented a specific production use of Cursor: most of the code for AITDK's SEO Issues module was completed using the editor.^[9] This supports a feature-level development attribution; the post does not establish that Cursor built the entire product.^[9]

Another first-person post compares Claude Code with Codex using the same prompts and says blank had switched primary coding work to Codex because fewer small problems occurred in that experience.^[10] This is a personal workflow report, rather than a controlled performance benchmark, and the post does not identify which Codex interface was used.^[10]

The public product history also includes using an existing directory template and initially delivering submission work manually, showing a combination of software development and service delivery.^[7][4]

Business Model

AITDK offers free website generators and core extension tools, alongside paid extension plans with larger credit allowances and more detailed traffic data.^[11] Its pricing documentation identifies backlink and Reverse AdSense lookups as credit-consuming actions.^[11]

SubmitDirs launched with paid submission packages and a defined delivery report.^[4] Traffic.cv keeps its traffic-checking tools free while selling monthly or annual Pro access to its leaderboards.^[12] These pages establish monetization mechanisms, but do not establish the founder's earnings.^[11][12]

Timeline

Lessons

The coding posts also support a narrower lesson: evaluate assistants against concrete development tasks and describe the scope of their contribution, rather than treating one successful feature or prompt comparison as proof of universal superiority.^[9][10]
