## SpeedAI

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.

- **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.

**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

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.

**Pricing & Plans:** Paid product with plans for individuals, teams, and enterprises; see the official pricing page for current seat prices and included features.
