How do I write a good prompt?
Include: the content type (blog post, email), the topic, the audience, the tone (professional/casual/persuasive), and any specific points to include. Example: 'Write a 200-word casual Instagram caption for a new coffee shop in Sydney targeting millennials.'
Is the generated content plagiarism-free?
AI-generated content is original — it does not copy existing content. However, for academic or professional use, always fact-check and personalise the output before submitting.
Can I use AI-written content for SEO?
Google allows AI content if it's helpful and high-quality. For best SEO results, add original data, specific examples, and your own expertise to AI drafts before publishing.

About AI Writing Assistant

A founder just drafted a 4-sentence LinkedIn post announcing a Series A and wants to expand it to a 300-word story with specific milestones and customer quotes without hiring an agency for one post. A customer support lead has written the same 'here is how to reset your password' reply 40 times this month and wants to draft a knowledge-base article that makes the next 40 tickets unnecessary. This assistant drafts, expands, polishes, and rewrites short-form writing using an AI language model — it is useful for overcoming blank-page freeze, getting a workable first draft you can edit, and compressing or expanding copy to fit a specific medium. It is not a journalist, a subject-matter expert, or a fact-checker. Output should always be read critically: AI can generate plausible-sounding text that gets details wrong, invents citations that do not exist, and occasionally confidently asserts things that are simply false. Treat it like an enthusiastic junior writer who reads quickly and writes faster than you — great for a first pass, needs careful editing before publication.

How it works

  1. 1

    Input plus mode determines the generation prompt

    Select a mode (expand, compress, polish, rewrite, draft) and paste or type your input. The mode picks a system prompt that instructs the AI on the target output — expand adds context and detail, compress extracts the essence, polish fixes tone and clarity, rewrite changes voice or style, draft generates new text from a brief.

  2. 2

    Output is a single draft, not a final version

    The AI returns one draft per request. You can regenerate for alternatives (each run produces a slightly different output because sampling is stochastic), copy back to input for iterative refinement, or edit inline before copying to your destination. No history is saved — each session is independent.

  3. 3

    Rate-limited and length-bounded

    Because inference is not free, requests are limited per IP per hour on the free tier (roughly 20 per hour). Input is capped at roughly 2,000 words to keep response time reasonable and within model context limits. For longer documents, break into sections and process separately, then assemble.

Pro tips

Always fact-check numbers, quotes, and specific claims

AI models are trained on text patterns and will confidently generate plausible-sounding facts that are wrong. A draft product announcement might say 'customers report 47 percent productivity increase' when no such study exists. A blog post about a regulation might cite a statute that has been repealed. Before publishing anything AI-drafted, verify every number, quote, statute, date, and named person against a primary source. This takes 10 to 30 minutes per 500 words and is non-negotiable. Skip it and you will eventually publish a false claim that damages credibility in a way no amount of good subsequent content can repair.

Use the AI for structure, not for expertise

AI is genuinely useful for breaking blank-page freeze, providing a scaffold you can react to, and handling the mechanical parts of writing (transitions, parallel structure, topic sentences). It is not a substitute for domain expertise. A medical professional writing patient education needs to verify every claim against clinical guidelines; a lawyer writing a client letter needs to confirm every cited case is still good law; an engineer writing API documentation needs to confirm the endpoint behavior matches the draft. Use AI for the writing, supply the expertise yourself, and keep the division of labor clear in your workflow.

Regenerate for variety, then blend the best parts

AI outputs vary run to run because of sampling randomness. Run the same prompt 3 times and you will get 3 different drafts — the first might have a strong opening, the second a better middle, the third a sharper conclusion. Instead of accepting the first draft, generate 2 or 3, then manually blend the strongest sections into a final version. This takes slightly longer than accepting the first output but produces noticeably better writing and reduces the specific-phrasing predictability that AI detectors increasingly pick up on.

Honest limitations

  • · AI can generate plausible-sounding text that is factually wrong; every claim must be verified against primary sources before publication.
  • · Not a substitute for domain expertise — supply the knowledge yourself and use AI for the writing mechanics.
  • · Rate-limited and inference-based, so not designed for bulk content production; keep to per-request drafts of under 2,000 words.

Frequently asked questions

Can I use AI-written content commercially and on my professional website?

Yes, with caveats. OpenAI, Anthropic, and most AI providers permit commercial use of generated text under their terms of service. Legal questions around copyright (can AI-generated text be copyrighted? Not under current US Copyright Office guidance for purely AI-generated work) and disclosure (should you tell readers?) are still evolving. For professional publishing, most outlets now require disclosure if AI contributed substantially to a piece, and for academic writing most universities prohibit undisclosed AI use. The safe path: use AI for drafting and editing, substantially rewrite to add your own voice and expertise, and disclose when the contribution was material to the final piece.

How do I prevent AI detectors from flagging my content?

Honest answer: heavy editing. AI detectors like GPTZero and Originality.ai look for statistical patterns in sentence length variation, vocabulary distribution, and structural predictability that AI output exhibits more than human writing. Lightly-edited AI text is easily flagged. Heavily-edited text — where you have rewritten sentences, added personal anecdotes, varied rhythm, and injected specific details the AI did not originate — becomes indistinguishable. There is no reliable trick to make raw AI output read as human other than actually reading and rewriting it substantially. If the goal is undetectable AI content, you are better off using AI as a drafting tool and then genuinely rewriting.

Is my input text stored or used to train AI models?

Your input is sent to our API which calls Anthropic's Claude. Anthropic's default terms (as of April 2026) do not use API inputs to train models, but you should verify current terms at anthropic.com/legal for the latest policy. We do not log or retain your input beyond the immediate request/response cycle. For absolutely confidential content (legal drafts, medical records, proprietary business documents, pre-embargo information), assess both our privacy terms and the AI provider's terms carefully, and consider on-premises or local-model alternatives where no data leaves your infrastructure at all.

Why does the AI sometimes produce generic or obvious text?

Because it optimizes for the statistically most likely next tokens given the prompt, and common patterns dominate. 'Write a LinkedIn post about my Series A' will produce generic LinkedIn-post-shaped output by default — the triumphant opening, the customer-thanks section, the humble-brag closing. To get better output, provide specific context in the prompt: the company name, the specific milestone, a customer quote you want included, a tone reference ('like paulg but warmer'). The more constraints and specifics you give, the less generic the output. Short vague prompts produce short vague drafts.

Can this replace a professional copywriter or editor?

No. Professional writers and editors provide strategic framing, audience insight, structural judgment, and domain knowledge that AI assistants do not replicate. What AI can do is make a mediocre writer faster and let a good writer iterate more. For high-stakes work — launch copy, fundraising narratives, crisis communication, legal-adjacent writing, medical content — hire a professional. For day-to-day internal writing, blog drafts, email polish, and first passes on longer work, AI is a useful accelerator that pays back the editorial review time. Treat it as a junior team member, not a senior replacement.

AI writing chains naturally with the adjacent tools. The paraphrasing-tool is the right next step when AI output is close but awkward — paraphrase the specific sentences that do not land. The grammar-checker catches residual mechanical issues in the final draft before publication. The word-counter verifies length fits the target format (LinkedIn post, email, blog post). For creators, the hashtag-generator and caption-generator handle downstream social distribution of the drafted content, and the ai-detector lets you check how likely a third-party reviewer would flag the piece as AI-generated before you publish.
