## CodeGateway

CodeGateway is an OpenAI-compatible and Anthropic-compatible gateway aimed at teams rather than individual developers. Instead of each engineer juggling separate provider accounts and cards, a workspace gets one API key that routes to the Claude, GPT, Gemini and DeepSeek model families. You invite members, assign owner, admin or member roles, and everyone draws from a single shared balance that is settled on one invoice.

The main practical advantage is setup simplicity. CodeGateway exposes Anthropic Messages, OpenAI Chat Completions and OpenAI Responses endpoints, so tools such as Claude Code, Cursor and Codex CLI work after changing the base_url — no code rewrite required. Requests are routed from Cloudflare's global edge network, which keeps latency consistently low wherever the team is based.

Pricing is deliberately transparent: a flat 1.07x markup on upstream provider list prices, with a 2% service fee applied only at top-up, and no monthly subscription. Balance never expires, so unused credit carries over indefinitely. Top-ups accept credit cards, Stripe Link, Alipay and bank transfer, and self-service refunds are available for unused balance. CodeGateway is operated by WHITEDIT LTD, registered in England and Wales.

**Pricing & Plans:** Usage-based pay-as-you-go with no monthly fee. Consumption is billed at a flat 1.07x markup over upstream provider list prices, with a 2% top-up service fee (plus card processing). Top-ups start from $5 and balance never expires; example packages are shown at $10, $20 and $50 tiers, with a free credit offered when you bind a card.

- **Team workspaces and shared balance:** Create a workspace, share one balance across members with owner, admin and member roles, and settle everything on a single invoice.
- **Multi-model, multi-protocol access:** One API key reaches Anthropic, OpenAI, Google and DeepSeek families through Anthropic Messages, OpenAI Chat Completions and Responses endpoints.
- **Usage and cost traceability:** Live token usage, cost breakdowns, per-member attribution and exportable billing so you know where spend goes.
- **Low-latency global routing:** Requests are served from Cloudflare's global edge, keeping latency low for geographically spread teams.
- **Security by default:** API keys are stored as SHA-256 hashes, traffic is HTTPS-encrypted and conversations are not inspected.

**Strengths:** One key and one bill for Claude, GPT, Gemini and DeepSeek; No monthly fee and balance never expires; Flat, transparent 1.07x markup regardless of spend tier; Drop-in compatibility with Claude Code, Cursor and Codex CLI via base_url change

**Limitations:** The 1.07x markup plus a 2% top-up fee makes it slightly costlier than going direct with a provider; It is a proxy layer, so it depends on upstream providers' availability and terms; No monthly plan may suit teams that prefer predictable flat billing

## GPTZero

GPTZero grew out of the practical problem that teachers and editors faced once generative text became common: how do you tell whether a piece of writing came from a person or a model? The product answers that with a detector that returns an overall AI likelihood score and highlights individual sentences it considers machine-written, so a reader can see where the suspicion comes from rather than just receiving a single verdict.

Over time the platform widened from a single text box into a suite aimed at institutions. Detector results are paired with a plagiarism checker, grammar and writing feedback, and optional process verification such as a writing replay that records how a document was typed. A Chrome extension and Google Docs add-on push detection into the tools students and staff already use, and the company offers classroom integrations plus an API for bulk or programmatic checks.

Because the buyers are largely schools, districts, and universities, GPTZero leans heavily on privacy and compliance claims: it states SOC 2 Type II compliance and alignment with FERPA, GDPR, and CCPA, and says student writing is not used to train models. The practical takeaway is that it is positioned as an academic-integrity and editorial-review tool rather than a novelty checker, which also means its more powerful features sit in paid tiers.

**Pricing & Plans:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **Sentence-level AI detection:** Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
- **Multi-model coverage:** Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
- **Browser and docs extensions:** A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
- **Plagiarism checking:** Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**Strengths:** Sentence-level highlighting shows why a passage was flagged instead of only giving a score; Covers text from many different AI model families, not just one chatbot; Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows; Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

**Limitations:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations
