## Ghostwrite

Ghostwrite targets the part of email nobody enjoys: staring at an empty compose window while trying to phrase a request, an apology, or an awkward ask. Instead of building the message from scratch, you hand over just the essentials — something like "ask the landlord to send a plumber quickly" — and the assistant drafts full prose you can polish.

The product leans on a friendly in-app helper persona, Inky, who is described as learning your style over time so drafts sound more like you the more you use the tool. The workflow is deliberately a three-step loop: give the details, receive the draft, then approve before sending. Nothing is sent on your behalf without your consent, which keeps a human in the loop on tone and factual accuracy.

Ghostwrite is aimed at people who find professional correspondence draining — job seekers, freelancers, people who dislike networking, and anyone dealing with high-stakes or socially awkward messages. It runs in the browser as a web app, so there is nothing to install, and it offers a free entry point with paid tiers for heavier use.

Note: Ghostwrite is an independent product and is not affiliated with, endorsed by, or produced by OpenAI or any other model vendor whose technology it may use.

**Pricing & Plans:** Freemium. A free entry point is offered through the Get Started flow, with paid subscription tiers for more usage. Specific tier limits are not published on the homepage, so check the site for current numbers.

- **Brief-to-draft generation:** Enter only the core facts of what you want to communicate and receive a complete, coherent email draft in return.
- **Personalised tone over time:** The assistant is designed to learn your phrasing and preferences so later drafts read closer to your natural voice.
- **Approve-before-send workflow:** Drafts are never dispatched automatically — you review, edit and add personal touches, then send the message yourself.
- **Built for difficult messages:** Handles the awkward end of correspondence: big asks, negotiations, apologies, cold outreach and follow-ups.
- **Browser-based access:** Runs entirely in the web browser with no installation or desktop client required.

**Strengths:** Turns a one-line brief into a full draft, cutting the blank-page problem; Human approval step means you keep control of tone and accuracy; Drafts reportedly adapt to your style as you keep using it; Simple, low-friction web interface with nothing to install

**Limitations:** No public pricing table on the homepage, so costs must be checked in-app; Output still needs a read-through for specifics, dates and names; Only covers email writing — no inbox management, scheduling or CRM features

## 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
