01 // OVERVIEW
Project Overview
A pipeline that unattendedly mass-produces save-worthy Instagram content - rankings, tier lists, infographics, and vocabulary charts - running the full flow from theme selection to WebSearch research, copywriting, gpt-image-2 image generation, video conversion, and posting. A single server and codebase runs multiple accounts across 4 languages (Japanese, English, German, and English-learning content), switching between fully automatic, semi-automatic, and Discord-review lanes per account.
02 // KEY FEATURES
Key Features
Fully Automatic from Theme Selection to Posting
Generates copy based on research verified via WebSearch, then creates images with gpt-image-2. Converts them into video and schedules posting, all without manual intervention. The direct cost per post is just a few yen for images plus LLM usage.
Centralized Management of Multiple Accounts and Languages
Runs multiple accounts covering 4 languages - Japanese, English, German, and English-learning content - from a single codebase. Account configuration files control content, language, posting frequency, and output lane.
Three Operating Lanes
Provides three lanes - fully automatic posting (posts directly with no phone notification), semi-automatic (generate -> phone notification -> assisted manual posting), and Discord review (manual posting after confirmation) - used according to each account's importance.
03 // TECHNICAL DEEP-DIVE
Technical Highlights
Solution
Reflecting Differences in Growth by Content Type in the Design
Adjusted the theme-selection logic based on the observed finding that "object-based topics that can be depicted photographically (sneakers, cars, watches) tend to go viral more easily, while conceptual topics grow more slowly." Content strategy for new accounts is decided using this data.
