TOOL 02

Blog Assistant In use · v4.16

A Windows desktop app we built with Claude Code. It turns job-site photos and notes into case-study posts for our Naver blog, then fills in the blog editor for us — so sharing a real case takes far less manual work.

Case-study postsFrom a real job's photos and notes: Claude picks the key photos and writes the post.
Informational posts from field dataClaude scores and ranks topics drawn from our field records; we pick from the top 10, and Claude drafts the title and post.
Photos & notesPick the job photos and write a few lines about the case.
Claude draftClaude picks the key photos and writes a structured case-study draft.
Editor automationEnters title, body and photos into the Naver blog editor.
Banner & tagsAdds the contact banner, phone link and tags.
Save or scheduleSaves a draft or schedules a private post, then verifies it.
Claude in useSince v4.16 (October 2026), the drafting step runs on the Claude API (Claude Sonnet 5.5): Claude selects the key job photos, writes the draft, and the app enters it into our Naver blog editor. Drafts are saved privately and published on our own schedule.
  • Per post: 2 API calls (photo selection, then the draft), about 7,900 tokens — roughly US$0.05.
  • Every run is logged with its model, token count and cost.
  • Every draft is reviewed by us before it is published.
