Description
SpeedAI is an AI-powered academic writing assistant focused on reducing text similarity (plagiarism) rates and AI-generated content (AIGC) rates. It intelligently analyzes text and offers varied rewriting suggestions to lower repetition while preserving the original meaning, and it uses a humanizing AI model to reduce AI-generation traces so writing reads more naturally and fits academic norms. According to the site, similarity can typically be reduced by 50 to 80 percent and AIGC rates on systems such as CNKI and VIP can be brought to around 10 percent.

The platform also offers academic polishing to improve scholarly expression and terminology, and an AIGC detection feature to check text for AI-generated traces. It is positioned as an English-facing AI humanizer and AI content detector as well, with the stated goal of transforming AI-generated text into human-like content and passing detectors such as GPTZero, Turnitin, and Originality.ai. The company reports over two million users and more than one million documents processed.
SpeedAI works with major Chinese detection systems including CNKI (知网), VIP (维普), Wanfang (万方), and Dayat (大雅). It advertises one-click full-text rewriting with logically coherent results and fast processing, rather than manual paragraph-by-paragraph editing. Data is protected with SSL encryption in transit and AES-256 encryption at rest.
Pricing is pay-as-you-go with no monthly fee, using points that never expire. Tiers include a Starter pack (10,000 points, about 2 yuan per thousand characters), a Professional pack (50,000 points), and an Advanced pack (300,000 points). New users receive 500 free points to start, and referring a friend grants 2,000 bonus points to both parties.
