## About AI Checker

AI Checker (AIチェッカー) is a free, no-signup Japanese text analysis tool. It uses statistical rules to surface writing features such as length patterns, stock phrases, sentence-ending habits, and repeated phrases, and can optionally add a DeepSeek-assisted style review. It does not claim to determine whether a text was written by AI.

## About posthell

posthell is a social media tool for small businesses. The owner writes one line about what happened this week, such as a free slot on Friday or a new dish, and posthell drafts a post for each network, including Instagram, Facebook, LinkedIn and TikTok.

Drafts are scheduled for the times the owner picks and wait in a review queue. Nothing publishes until the owner approves it, and any word can be changed first. Posts can use AI images, free stock photos or the owner's own pictures.

It is built for cafes, salons, clinics, gyms, trades, shops and online stores, and for agencies and freelancers who post for clients. Accounts connect through each network's own login. Technical users can also draft through an MCP server or a CLI.
