AI WORLD HQHow to Write a Cover Letter With Any AI Assistant
Turn a blank page into a tailored first draft in about 15 minutes, so you can apply for more of the right jobs.
Hook: By the end of this guide you'll have a personalised cover letter draft you can edit and send — even if you've never used an AI assistant before. It's for anyone applying for jobs who'd rather spend their energy choosing which roles to apply for, not staring at a blank page.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- An AI assistant account. Any mainstream one will do — ChatGPT, Gemini, Claude, Copilot, Le Chat, DeepSeek or similar. A free plan is enough for this task; paid plans just give you more messages or longer replies.
- The job ad (or your notes about the role). Either the full advert copy pasted somewhere, or a few sentences about the role and company. You'll feed it into the assistant in Step 2.
- A short note about you. Two or three sentences about your background — your current role, one or two relevant wins, and what you're looking for next. The more honest and specific, the better the draft.
- Roughly 15 minutes. That's enough to gather your notes, run the prompt, and do one editing pass.
- Honest expectation: the assistant will draft the letter for you. It cannot apply for the job, attach your CV, or speak to the employer on your behalf — those parts are still you.
Open a fresh conversation in your AI assistant
Open your AI assistant in a browser or app and start a brand-new chat. What you see: an empty message box at the bottom of the screen, usually with a placeholder like "Message…" or "Ask anything". What happens next: nothing yet — the assistant waits for your first instruction. If it looks different: any assistant will do, so if you can't find the "new chat" option, just close the old conversation and open a new tab or window; the next message you send will start fresh. You'll know it worked when… you see an empty chat with no previous messages above the input box.
Paste the job ad and your background into the chat
In that empty message box, paste the job advert (or a summary of it) and then, on the next line, your short note about yourself. What you see: the job text followed by a paragraph about you, all sitting in one message. What happens next: the assistant reads both pieces together and starts to work out what's relevant. If it looks different: if the advert is very long, a short summary is fine — bullet points like "Role: Office Manager. Location: Brisbane. Must have: Xero, scheduling, customer emails" works just as well as full text. You'll know it worked when… the assistant replies with at least one clarifying question (e.g. "What's the tone you want — formal or conversational?") instead of jumping straight to a draft.
Ask for a tailored first draft
Once the assistant has asked its questions (or you've answered them in the same message), reply with one clear instruction: write a first draft aimed at this specific role. What you see: the assistant begins typing a response in paragraphs — an opener, a middle section about your experience, and a short closing. What happens next: a complete draft letter appears, usually in 200–350 words. If it looks different: if the draft feels too short or too generic, that's normal — you'll tighten it in Step 4. The first pass is meant to be a starting point, not the final letter. You'll know it worked when… there's a full letter on screen with a greeting, body paragraphs, and a sign-off — even if some parts feel a bit "vanilla".
Edit the draft to sound like you
Copy the draft into a document (Google Docs, Word, or even the Notes app). Read it aloud once — every awkward phrase will jump out. What you see: your draft in an editor where you can freely change words. What happens next: you tighten sentences, swap any stiff phrases for words you'd actually say, and cut anything that doesn't match your real experience. If it looks different: if a phrase feels too formal for you, shorten it; if a paragraph is empty filler, delete it and replace it with one true sentence about yourself. The assistant wrote it in seconds, so it's fine to rewrite half of it. You'll know it worked when… you can read the letter out loud without cringing and every sentence is something you'd genuinely say in an interview.
Save the prompt that worked so you can reuse it
The exact instruction you used in Step 3 is now a template you can adapt for every other application. What you see: your original prompt saved somewhere handy — a notes app, a Google Doc titled "Cover letter prompt", or even an email draft to yourself. What happens next: next time you apply somewhere, you change only the role details and the "about me" part, then run the same prompt again. If it looks different: if you'd rather not save it digitally, screenshotting the conversation works too. You'll know it worked when… the next cover letter takes you roughly five minutes of editing instead of forty minutes of staring at a cursor.
- Mistake: Letting the assistant invent experience you don't have. Fix: in Step 3 add a line like "don't make up any experience I haven't told you about". Then delete anything in the draft you can't back up in an interview.
- Mistake: Sending the first draft without reading it. Fix: always do one slow read aloud in Step 4. Hiring managers can spot an untouched AI letter within a few sentences — usually because the voice doesn't match your emails or the CV attached.
- Mistake: Using the same draft for every job. Fix: run the prompt again with each new job ad. A personalised paragraph naming the company or role is the single biggest difference between letters that get replies and ones that don't.
Open your AI assistant right now, paste the job ad for a role you genuinely like, add three sentences about yourself, and ask for a 200-word draft with the instruction "don't invent any experience I haven't given you". You'll have your first usable cover letter before the kettle boils.
