## Overview

SpeedAI is aimed squarely at the Chinese academic writing pipeline, where two separate checks decide whether a paper survives: a similarity (repetition) check against published literature, and an AIGC check for traces of machine generation. The service bundles both sides of that problem into one dashboard, offering simulated detection first so you can see where you stand, then rewriting tools designed to bring the numbers down.

The detection side covers the platforms Chinese students actually face — CNKI (知网), VIP (维普), Gezida (格子达), Daya and Wanfang — alongside a generic 'overseas' mode. The site states that free AIGC checks are available five times a day, that it has processed hundreds of millions of characters for over a million users, and that its simulated results sit within roughly 10% of official figures. Those are vendor-reported numbers; treat them as marketing rather than independent benchmarks.

The rewriting side splits into repetition reduction, which varies phrasing against source literature, and AI-rate reduction, which reworks sentences to remove machine-writing patterns. SpeedAI also offers academic polishing for tone and terminology. Everything is delivered as a web app with a whole-document workflow, and the vendor deliberately emphasises that submissions are encrypted in transit and at rest — a fair signal that data sensitivity is the main objection users raise. Anyone using it for graded work should first check whether their institution permits AI rewriting assistance at all.

## Pricing & Plans

SpeedAI runs on a free-allowance plus paid model. AIGC detection is advertised as free five times per day, and periodic promotions grant free character quotas for rewriting. Paid usage is priced by volume of characters processed; exact rates are not published on the homepage and appear in-app after login.

## Key Features & Capabilities

- **Multi-platform AIGC detection:** Run checks modelled on CNKI, VIP, Gezida, Daya, Wanfang and an overseas detector to see how AI-generated your text looks before you submit it.
- **AI-detection rate reduction:** Dedicated rewriting optimises passages so they carry fewer traces of machine generation, with the vendor reporting typical results under 10% on the simulated platforms.
- **Repetition rate reduction:** A separate rewriting mode targets similarity against published literature, offering varied phrasings while keeping the original meaning intact.
- **Whole-document rewriting:** Document-wide processing that rewrites the whole paper at once rather than forcing you to edit paragraph by paragraph.
- **Academic polishing:** Improves academic tone and terminology usage so that the rewritten text still reads like formal scholarship.

## Primary Use Cases

- **Pre-submission AIGC check (Graduate students):** Check a chapter against simulated CNKI and VIP detectors before submission, then rewrite the passages that flag highest.
- **Lower repetition rate on a draft (Thesis writers):** Bring a manuscript's similarity score down by rewriting overlapping phrasing while preserving citations and meaning.
- **Humanise AI-assisted sections (Researchers drafting with AI help):** Run exported AI-assisted sections through the rewriting and polishing modes so the language reads as consistent academic prose.
- **Batch-process long documents (Report and grant writers):** Use document-level processing for long reports where manual line-by-line rewriting is impractical.

## Strengths

- Covers the specific Chinese detection platforms students actually encounter rather than only Western ones
- Detection and rewriting live in one workspace, so you can measure then fix without switching tabs
- Free daily detection quota and promotional character allowances let you test quality before paying
- Whole-document processing is far faster than editing paragraph by paragraph

## Limitations

- The interface and most supporting material are built around Chinese academic databases such as CNKI and VIP, so it is less relevant to Western submission workflows
- Heavy focus on 'reducing AI rate' for graded or published work raises academic-integrity questions at many institutions
- Because detectors and their models change constantly, no rewriting tool can guarantee a particular score
- Reported outcomes are based on self-published user feedback rather than independent third-party studies

## Frequently Asked Questions

### What is SpeedAI?
SpeedAI is an academic productivity website for Chinese researchers and students. It offers AIGC (AI-generated content) detection, tools that reduce repetition rates and AI-detection rates, and academic language polishing, all in one workflow.

### Which detection systems does it simulate?
The AIGC detection module publishes simulated checks for CNKI, VIP, Gezida, Daya, Wanfang and an 'overseas' detector. The homepage states free detection is available five times a day, and that reported results differ from official ones by less than 10% on the platform's own measurements.

### Is there a free tier?
The site charges nothing for a set number of daily AIGC checks and periodically runs promotions offering free character allowances for rewriting. Beyond those free allowances it is a paid service; specific per-character or per-paper prices are shown in-app after you log in.

### Is my text safe to upload?
SpeedAI says all transfers are SSL-encrypted and stored data is protected with AES-256, and that it does not use submitted content for unauthorised purposes. You should still judge for yourself whether uploading thesis material to a third-party site fits your institution's rules.

### Should I reduce repetition or AI-detection rate first?
The vendor recommends lowering the repetition rate first, then the AI-detection rate, because the two are measured differently: similarity against published literature versus traces of AI generation.

### What is SpeedAI's monthly traffic and growth trend?
SpeedAI currently receives 461 monthly visits, with a month-over-month traffic change of -3.94K (-89.5% growth rate). Its primary source market is China (100% share), including 189 direct visits/mo and 0 organic search visits/mo.
