# AI Tools for Marketing, by Task: What ChatGPT, Claude, Jasper, HubSpot and Canva Do and Cost > Most marketing work needs a general AI assistant, an image or video generator and the AI already in your marketing platform; here is what each does and costs. By Pat Simmons · November 13, 2026 · 13 min read Canonical: https://www.aiformortals.co/blog/ai-tools-for-marketing Most marketing work needs three kinds of AI tool. The first is a general assistant (ChatGPT, Claude or Gemini) for copy, briefs, repurposing and research. The second is an image or video generator for ad creative. The third is the AI already built into the marketing platform you use, such as HubSpot's Campaign Assistant, which HubSpot says is 100% free and writes landing page, email and ad copy. All three general assistants have a free plan. ChatGPT's paid plans start at $8 a month for Go, and Plus costs $20 a month. On video, Pat Simmons made a one-minute Seedance 2.5 explainer for about $15 through Replicate, a site that runs AI models for a per-use fee (more in our guide to what each AI video generator costs). Below are a table of what each tool does and costs, taken from each tool's own pages, and starting prompts you can copy for each job. Last checked November 13, 2026: prices and free plans for ChatGPT, Claude, Gemini, Jasper, HubSpot Campaign Assistant, Canva, Seedance 2.5 on Replicate and Google Vids, each linked where it's first stated on this page.

Most marketers can cover the work with a general assistant and an image or video tool, plus the AI in the platform they already use. Pat hasn't tested marketing tools against each other, so this page sorts them by job and price and doesn't rank them. A general assistant. ChatGPT, Claude and Gemini all draft, rewrite, summarize and research. ChatGPT's free plan includes unlimited everyday text chats, and the limits that remain apply to uploads, images, voice and other tools. Plus, at $20 a month, is the plan where ChatGPT Work, deep research and Codex usage expand. Claude's free plan includes web search, file creation, Slides and Docs, with usage limited every five hours and every week. Pro is $20 a month, or $17 a month if you pay $200 for the year up front. Gemini's free plan comes with any Google account and includes image generation and editing and Deep Research. Google AI Plus costs $4.99 a month and adds video generation and double the free usage limits; Google AI Pro is $19.99 a month. An image or video generator. ChatGPT and Gemini both make images on their free plans, in limited amounts. For video, the sections below cover Seedance, the model Pat used for product ads, and Google Vids, which has a free allowance. The AI inside your marketing platform. If your team already runs on HubSpot, Canva or Jasper, their built-in AI writes in the place where the campaign gets published. The platforms section below covers what each includes. ## How is AI used in digital marketing? In digital marketing, AI writes and rewrites copy, makes images and videos for ads, researches audiences and competitors, and turns one piece of content into many. The vendors describe the same jobs on their own pages: HubSpot built Campaign Assistant for landing pages, emails and ads for Google, Facebook and LinkedIn, and Google lists writing scripts and social copy among Gemini's uses on its plans page. Pat's own videos show two marketing jobs done this way. In one, a Make.com automation saves the transcript of his latest YouTube video to a Google Doc, and Claude reads it, writes a blog post "based off of my previous writing" and publishes it to his site (from 0:20 in his YouTube-to-blog video). In another, he had Claude Code build him a custom X feed that shows only the people he picks and helps draft replies "in my voice" (his X reply-feed build). ## How do you use ChatGPT for content creation? Use ChatGPT as an editor and a repurposing tool: give it your draft or source material, say who it's for and what format you need, then check every fact it touches. That's the approach in our guide to using ChatGPT as an editor for your drafts, and it works the same way for marketing copy. Paste in the real material: the blog post, the product page, the brief. Anything it adds that you didn't give it (a statistic, a customer quote, a feature) is something you have to verify before it goes out. If you write for one brand all the time, set custom instructions so ChatGPT writes in your brand voice: the words you use, the words you never use, and how long your posts run. Jasper sells the same idea as a feature, with 2 saved Brand Voices on its Pro plan. The three prompts below were written for this page as starting points. Swap in your own details. Turn a blog post into social posts **Repurpose a blog post** ``` Below is a blog post from [company], written for [audience]. Turn it into 5 LinkedIn posts and 5 short posts for X. Each post makes one point from the article, in plain words, and ends with a link placeholder [LINK]. Use only facts that are in the article. If a post needs a number the article doesn't give, leave a gap and tell me. Match the tone of the article. No hashtags, no emojis. [paste the blog post] ``` Write ad variants from a brief **Ad copy variants** ``` Here is our campaign brief: [product], [who it's for], [the one thing we want them to do], [offer and deadline]. Write 6 versions of a Facebook ad, each with a short headline and two lines of body text. Make 2 of them lead with the problem, 2 with the result, and 2 with the offer. Don't invent claims, prices or reviews. Then tell me which 2 you would test first and why. ``` Build a content calendar from a product page **Content calendar** ``` Read this product page: [paste the text or the link]. Plan 4 weeks of content for [channels] for [audience], 3 posts a week. Put it in a table with columns: date, channel, topic, the product feature it covers, and a one-line hook. Spread the posts across different features, and flag any feature where you're unsure what it does instead of guessing. ``` ## AI for ad images and product videos For ad images, the image tools inside ChatGPT, Gemini and Canva can make mockups and ad graphics from a written description. For product videos, Pat's beginner guide shows the full process with Seedance 2.0: Claude writes a shot-by-shot prompt from one product photo, and Seedance turns it into an edited multi-shot ad. Ad images and mockups In his ChatGPT Images 2.0 video, Pat made a couple of what he called "marketing assets" with the image model, starting with a landing page for a made-up journaling app called Fieldnote (from 9:35 in his ChatGPT Images 2.0 video). He called the result a "really good mockup of the iPhone" that "feels much more like a landing page" than the versions from GPT Image 1.5 and Nano Banana, and he pointed out "those, you know, cheesy icons that AI always adds." _The Fieldnote landing page ChatGPT Images 2.0 made from one prompt, in Pat's video at 9:51._ Canva's pricing page lists "Create ads with AI and creative insights" on every plan, including Free, which comes with limited access to its AI tools. Pro costs US$144 a year for one person and gives 10 times the Free plan's AI allowance; Business is US$250 a year per person. Product ad videos from one photo Pat made four product ads in his Seedance 2.0 guide, each from a single product photo: AirPods, a Wild Roman skincare jar, a Liquid Death can and a New Balance running shoe. Seedance is ByteDance's video model, and Pat ran it in Higgsfield's Create Video tool. His first rule is about the prompt: "create a cinematic product ad" is too vague, and you want to be specific about lighting, camera movement and shot timing. He built a Claude skill that turns a product photo into a timed shot list, and he shares it free on GitHub, linked from the video's description. Seedance calls this multi-shot generation: one prompt with timestamps becomes one video with cuts between the shots. _Claude writing a timed shot list for the AirPods ad from one product photo, at 3:08 in Pat's product-ad video (embedded below)._ He pasted each shot list into Higgsfield with the product photo and generated the clip. He set the AirPods ad to 16:9 and cut it from 15 seconds to 8, because 15 "felt a little too long for a quick product video like this." _The Wild Roman skincare ad Seedance 2.0 made from one product photo, playing in Higgsfield at 7:50 in Pat's product-ad video._ Two of his working habits carry over to any ad. When a clip looks off, he goes back to Claude, describes what's wrong and has it update the prompt. When he doesn't know a category's ad style, he searches Facebook's Ad Library for what other brands run, then shows Claude an example and asks it to "make it look like this." He also named the flaws: the Liquid Death can's lettering came out wrong, the shoe's rotation had odd physics ("I don't think this model is great at physics yet"), and he thought one logo came out backwards. Higgsfield checks every uploaded image before it generates; Pat's own face went through once he accepted the terms, and as he understood it, uploading someone else's face is still a violation. For cost, Replicate's Seedance 2.5 page charges $0.2312 a second of video at 720p and $0.1028 at 480p, when you don't feed it a video. That's in line with the roughly $15 Pat spent on his one-minute explainer, music and voiceover included (the cost breakdown is in the video generator guide linked at the top of this page). For a free start, Google Vids lets anyone with a Google account make up to three 15-second videos a month at no cost. The same guide compares Kling, Runway and Grok Imagine. In the video: writing the prompt with the Claude skill (0:41), generating the AirPods ad in Higgsfield (4:06), the skincare ad and the Facebook Ad Library trick (5:50), the Liquid Death can (7:57), and the running shoe with a photo of Pat's own face (8:40). ## Marketing platforms with AI built in: HubSpot, Jasper, Canva HubSpot's Campaign Assistant is free and writes copy for a campaign you've already planned, Jasper is a paid marketing content platform built around your brand voice, and Canva puts AI into the design tool where ads and social graphics get made. HubSpot Campaign Assistant HubSpot says Campaign Assistant is "100% free with no subscription fees, per-campaign costs, or usage limitations." You give it three things (your campaign objective, your target audience and your brand's tone), and it writes landing page copy, marketing emails with subject lines, and ad copy for Google Ads, Facebook and LinkedIn. The page labels it a public beta, and clicking through to the tool took us to a HubSpot sign-up page. _HubSpot's Campaign Assistant page, screenshot taken November 13, 2026, from hubspot.com._ HubSpot also sells a bigger tool. Campaign Agent, in beta in Marketing Hub Professional and Enterprise, plans the campaign from your HubSpot data and brand identity, and HubSpot's Content Agent then builds the assets. Jasper Jasper's Pro plan costs $69 a seat a month, or $59 a month billed yearly, and you can try it free for 7 days; there's no free plan. Pro includes one seat, 2 Brand Voices, 5 Knowledge assets, 3 saved audiences, and "agents for core marketing workflows." The Business plan has custom pricing and adds agents for translation, deep research and GEO (getting your brand into AI search answers). More on what Jasper does is on our Jasper page. Canva Canva's AI tools share a monthly allowance that depends on your plan, and more complex tasks use more of it. Free gets limited access, Pro gets 10 times the Free allowance and adds social scheduling, and Business gets 20 times the Free allowance, with approvals and 100 brand kits. ## AI agents for marketing: what they can do today AI agents can now research, draft and plan marketing work over hours or days, and the ones built for it sit on the higher-priced plans. OpenAI's dots need ChatGPT Pro (from $100 a month), Business Premium or Enterprise; HubSpot's Campaign Agent needs Marketing Hub Professional or Enterprise; Jasper's broader agents are on its custom-priced Business plan. OpenAI's Dots page describes one marketing use: for content creators, a dot learns your voice and audience, finds interview moments to clip, and drafts show notes and social posts for you to approve. Pat tested Dots when it launched and gave his dot a marketing job: research how well-known newsletters grew and work out what he could still apply to his own (from 23:22 in his Dots video). It produced a 30-page PDF. He said he hadn't looked through it yet, asked for the top line, and called that "kind of generic." When he pushed back, it named more specific growth tactics, and he said "some of these are actually really good." ## Which AI marketing tools are free? HubSpot's Campaign Assistant is the only tool on this page whose maker calls it free with no usage limits. ChatGPT, Claude, Gemini and Canva have free plans with limits, Google Vids gives three free 15-second videos a month, and Jasper offers only a 7-day trial. - HubSpot Campaign Assistant: free, per HubSpot, in public beta - ChatGPT Free: unlimited everyday text chats, limited images and uploads - Claude Free: limited usage every 5 hours and every week - Gemini Free: image generation and Deep Research with a Google account - Canva Free: templates plus limited AI, including making ads with AI - Google Vids: up to three 15-second videos a month A small business can draft and repurpose in ChatGPT, Claude or Gemini, write campaign copy in Campaign Assistant and make graphics in Canva without paying. Video is where you start paying, by the second on Replicate or by plan elsewhere. ## What not to paste into an AI tool at work Keep customer lists, unreleased campaign results, contracts and anything under an NDA out of a personal AI account unless your company has approved that tool. On ChatGPT Free, Plus and Pro, data sharing for model training is on by default; you can turn off "Improve the model for everyone" in Settings and keep your chat history, and Temporary Chats aren't used to improve OpenAI's models. OpenAI says it doesn't train on data from ChatGPT Business and Enterprise by default. Check your company's AI policy first; if it names an approved tool, use that one. Our guide on what each AI app keeps from your work chats goes plan by plan. ## Questions people ask Is HubSpot's AI Campaign Assistant free? Yes.
