## WriteGO

WriteGO is built around a simple idea: if a draft is supposed to be grounded in sources, the sources should survive the whole trip from reading to final review. Its ChatPDF tool answers questions about a paper using retrieved excerpts and checks citations verbatim against the document, so a claim stays tied to the page it came from. Those quotes can be captured as evidence notes, and each note re-checks itself against the current document rather than drifting out of date.

From there, the Writer Agent turns selected evidence into a resumable drafting workspace. You approve an outline, the agent drafts from exactly the quotes you picked, and the work can be paused and picked up later with context intact. This keeps generated text traceable to specific sources instead of producing plausible-sounding prose with no anchor.

WriteGO also includes a review side. Integrity Review produces findings that must quote your own text verbatim — a finding whose excerpt is not found in the document is discarded before the report is shown — and the AI Detector offers explainable signals rather than a single opaque score. Detection is presented as supporting evidence in a review workflow, not as proof of authorship. Supporting aids such as a grammar checker, rewriter, summarizer, paraphraser, translator, and citation generator round out the toolkit, and credits are only charged on successful runs.

**Pricing & Plans:** Free tier with credits (up to 90 credits per month via daily check-in); Pro at $19.9/month with 300 credits; Premium at $29.9/month with unlimited usage and 800 credits/month; a Lifetime plan at a one-time $599. Extra credit packs range from 650 credits for $14.99 to 10,000 credits for $179.99.

- **Page-cited research reading:** The ChatPDF tool answers questions about a paper using retrieved excerpts and verifies citations verbatim, so answers stay tied to a specific page.
- **Writer Agent drafting workspace:** Turn an approved outline and selected evidence into a draft in a resumable workspace that carries your quotes forward without pasting blind.
- **Integrity Review on your own text:** Findings must quote your document verbatim and are discarded if the excerpt cannot be found, so every flag points to something you can check.
- **Explainable AI detection:** The AI Detector surfaces review signals you can inspect rather than a single black-box percentage, and is framed as supporting evidence.
- **Full revision toolkit:** Grammar checker, rewriter, summarizer, paraphraser, translator, citation generator, and scholar search support the writing and revision stages.

**Strengths:** Citations are checked verbatim against the source with page numbers retained; Integrity findings must quote your actual text, which keeps reviews verifiable; Writer Agent is resumable, so long documents can be built across sessions; Failed work is not billed and unlimited plans stay unmetered

**Limitations:** Credit accounting adds a layer of planning on top of writing; Detection is presented as supporting evidence, so it cannot conclusively settle authorship questions; Best value comes from the workflow as a whole rather than any single tool used alone

## Z.ai

Z.ai is the consumer-facing assistant from Zhipu AI (Zhipu / Z.ai), the Chinese lab behind the GLM series of large language models. The chat product lives at chat.z.ai and is positioned as a broad, free workspace: you can hold a normal conversation, ask it to write or summarise, and — its most distinctive angle — ask it to generate things. The landing page advertises full-stack app creation, writing, data insight and analytics views, presentation decks and whole web sites, all from a text prompt.

The experience is deliberately low-friction. A guest mode lets you start typing immediately without creating an account, and the interface surfaces a model picker with fast GLM Flash variants for quick generation. When you want history, saved work or higher limits you log in. Behind the chat, the same platform offers API access and developer tooling, so Z.ai serves both as an end-user assistant and as the public face of Zhipu's model lineup for builders.

Because it is free to try and requires no payment details, Z.ai is often compared with ChatGPT as a no-cost alternative — though the comparison is only partial. It is a Chinese-origin platform, so the interface, default language handling and data policies reflect that, and the very strongest GLM models sit behind accounts or paid tiers. For prompt-to-artifact work such as decks, pages and small apps, however, it is a genuinely capable free option.

**Pricing & Plans:** Free to use. Chat and generation modes are available at no cost, and the guest mode needs no account or payment details. Zhipu AI also sells paid access and API plans for higher limits and its strongest GLM models, but the web chat at chat.z.ai is usable for free.

- **AI slide and deck generation:** Describe your topic and Z.ai drafts a slide deck with structured layouts, headings and visual placeholders you can refine with follow-up prompts.
- **Code and app generation:** Paste a brief or a bug report and it will produce code in common languages, and it can scaffold functioning web pages and small full-stack apps.
- **Everyday writing and chat:** Chat, brainstorming, rewriting, translation and summarising all run through the same prompt box, with GLM Flash models keeping responses quick.
- **Web search and research:** Ask a question and it can ground the answer in web sources rather than relying only on its training data, useful for current facts and comparisons.
- **Guest mode with no login:** You can start a conversation without signing in, then create an account later to keep history and unlock higher limits.

**Strengths:** Free to try with a guest mode that needs no account or payment details; Strong at turning prompts into real artifacts: slide decks, web pages and working apps; Built on Zhipu's GLM models with fast Flash variants for quick responses; Covers chat, writing, coding, search and generation in one interface

**Limitations:** Free tier relies on the faster GLM Flash models, with the strongest variants reserved for signed-in or paid tiers; Chinese-origin platform, which some teams rule out for data-handling reasons; Feature quality varies by mode; complex slide decks or full apps usually need follow-up prompting; Account features and some limits require sign-in even though guest chat is available
