AI Writer — what it does
Writes a complete first draft — blog post, article, landing page, product description, LinkedIn post, newsletter, YouTube script or social captions — and gives you a plan you can actually edit. Two engines share the page: bring your own OpenAI, Gemini, Groq, OpenRouter or DeepSeek key and the model writes the draft with title options, meta description, sections, CTA and SEO notes; or leave the key out and offline mode builds the writing plan — title options, a section-by-section word budget with what each section must cover, a quality checklist and a ready-to-paste prompt.
How to use AI Writer
- Describe the piece in the Brief field. The more specific the brief (audience, angle, what to avoid), the less editing you do afterwards.
- Pick the format, tone and target length. The format decides the section plan: a landing page gets hero, proof, features and FAQ; a newsletter gets subject lines and a story.
- Add keywords if you are writing for search. They are placed naturally, never stuffed.
- Choose the engine. Offline needs no key and sends nothing anywhere; AI uses the provider you configured in Settings → AI & BYOK.
- Run it, read the draft, then copy the Markdown or download the .md file. Edit before publishing — the tool never claims to have checked a fact for you.
Worked example: a blog post that does not sound generic
Brief: “Why running PDF tools in the browser beats uploading files to a cloud converter, with a 4-step workflow anyone can follow”, audience “small business owners and accountants”, 800 words, keywords “pdf tools, privacy”. Offline mode returns eight sections with a ~100-word budget each, the exact points each section must cover, a title under 60 characters, and a prompt you can paste into any chat tool. AI mode writes those sections as full prose and adds FAQ answers plus a list of things to fix before publishing.

Frequently asked questions
- What is AI Writer?
- Write a full blog post, article, landing page, LinkedIn post, newsletter or YouTube script with your own LLM provider — title options, sections, CTA and SEO notes. No key? Offline mode builds the complete writing plan and a ready-to-paste prompt instead.
- Is AI Writer free to use?
- Yes — AI Writer is free to use, with no sign-up, no install and no account.
- Does AI Writer upload or store my data?
- No — processing happens in your browser. AI requests go directly from your browser to the AI provider you connect with your own key, so your data never touches a SarvTools server.
- How does the AI in AI Writer work?
- It uses a bring-your-own-key model: you connect your own provider (OpenAI, OpenRouter, Groq, Gemini or DeepSeek) in Settings, and your key stays in your browser.
- Do I need an API key to use the AI Writer?
- Only for the AI engine. Offline mode runs with no key and no network at all: it produces the full writing plan, title and meta-description guidance, and a prompt you can use in any chat assistant.
- Does it sound like AI?
- The draft is only as good as the brief and the model. The system prompt forbids filler openings and repeated ideas, and asks for concrete numbers — but you still rewrite the parts that make you sound like you. Treat the output as a strong first draft, not a final one.
- Where does my text go?
- Nowhere, in offline mode. In AI mode the brief is sent from your browser directly to the provider you configured; the key is stored locally in your browser and SarvTools has no server in the middle.
