Best AI for ad copy

Every ad copy tool, one by one

Jasper and Anyword charge more than a chat assistant for a shared brand voice or a predicted score. The seven ad generators write copy beside the image.

Claude

Claude Pro lists $20 a month, and a Team seat $25 a month (Claude pricing). Anthropic “may not train models” on Team chats (Commercial Terms B); consumer chats train its models unless you opt out (Consumer Terms 4).

Marketers use it for hooks and ad copy (8 of 44 sources: Reddit, Reddit). In one creator’s $100 Meta split test, its copy cost about 20% less per lead than his own (YouTube, 10 August 2026). Usage limits are the top complaint, paid plans included (11 of 44 sources: Trustpilot, App Store). It makes no images.

Best for

Writing and iterating hooks, headlines, scripts and briefs from your own research, reviews and past winners, and working through exported ad data.

Not for

Making the ad image itself: Claude does not generate images, so it pairs with an image tool.

Back to the tool list

ChatGPT

ChatGPT writes the copy and makes the image in one chat. OpenAI’s pricing page renders consumer prices by region in the browser, so the table lists them as Unverified. OpenAI’s terms say you “own the Output”, and chats train its models unless you opt out.

Its sharing policy asks that content posted to social media be marked as AI-generated, without saying whether a paid ad counts. Image limits are unpublished and move from day to day (8 of 34 sources, all on Trustpilot).

Best for

Hooks, copy and the matching image in one chat, plus API images at $0.053 each (medium quality, 1024x1024).

Not for

Anyone who needs a published image quota per plan, or pixel-exact brand fonts and layouts without a finishing pass in a design tool.

Back to the tool list

Gemini

Google AI Plus, the cheapest verified paid plan of the 13 tools, lists $4.99 a month (Google AI plans). Nano Banana makes the image in the same chat.

For copy alone, Gemini trails Claude and ChatGPT in the few head-to-heads users ran (3 of 38 sources: YouTube, YouTube). In one creator’s Meta split test of all three, its copy had the highest cost per lead (YouTube, 10 August 2026).

Google’s terms say only that it “won’t claim ownership”, so ad use is unclear. Chats improve its models unless Keep Activity is off (Privacy Hub).

Best for

Drafting hooks, headlines and scripts next to Nano Banana images in one chat, on the free plan or Google AI Plus at $4.99 a month.

Not for

Teams that need a published message quota: Gemini’s limits are compute-based, refresh every 5 hours up to a weekly cap, and no number is published.

Jasper: ad copy in a shared brand voice

Jasper Pro lists $69 a month per seat, with 2 Brand Voices, 5 Knowledge assets and a 7-day trial (Jasper pricing). Brand Voices are the feature users praise most: drafts stay close to their tone across projects and team members (8 of 44 sources: YouTube, G2).

Its templates cover Facebook and Instagram ads and headlines (6 of 44 sources: G2, Capterra). Some marketers see no gain over prompting ChatGPT, Claude or Gemini directly (3 of 44 sources: Reddit, Reddit).

Billing tops the complaints: trials that turn into annual charges and refused refunds (13 of 44 sources: YouTube, Trustpilot). Terms 3(a) take a perpetual licence to your copy for “modifying, improving, and enhancing artificial intelligence models”; only EU and UK users may object (section 12).

Best for

Marketing teams that need many people to produce on-brand copy from shared brand voices, product knowledge and audiences.

Not for

A solo media buyer who only needs ad hooks and headlines; a general assistant does that for a fraction of $69 a seat.

Back to the tool list

Anyword

Anyword’s Starter lists $49 a month for one seat and 50 performance predictions a month, 100 on yearly billing (Anyword pricing). The score is why users pick it (9 of 23 sources: YouTube, Trustpilot).

Price is the main complaint (8 of 23 sources, all on G2). Its terms (section 4) give you “all right and title in the Generated Content”.

Best for

Marketers who want copy variants ranked before launch and, on Business, a model trained on their own past ads and channel data.

Not for

Anyone expecting the score to replace a live test; Starter includes 50 performance predictions a month on monthly billing (100 on yearly).

Back to the tool list

Copy.ai: from ad copy generator to sales workflows

Copy.ai’s Chat plan lists $29 a month for 5 seats with OpenAI, Anthropic and Gemini models; every larger plan adds workflow credits (Copy.ai pricing). Fullcast bought it in October 2025, and users say the move took away writing features they paid for (4 of 31 sources: YouTube, Trustpilot).

Several users now get the same or better copy from ChatGPT or Claude for less (4 of 31 sources: Trustpilot, Reddit). Support is the top complaint (12 of 31 sources, all on Trustpilot). Its terms name OpenAI as owner of what it writes (below).

Best for

Sales and RevOps teams building outbound and campaign workflows; the Chat plan gives 5 seats access to OpenAI, Anthropic and Gemini models.

Not for

Performance marketers shopping for an ad copy tool: the product has moved to GTM automation, and the terms still name OpenAI as owner of generated copy.

Back to the tool list

AdCreative.ai

AdCreative.ai writes ad copy beside its banners. Starter lists $39 a month for 10 credits, $3.90 per image if every credit is used (pricing). Users report the 7-day trial turning into a large charge, found months later by some (18 of 34 sources: G2, Reddit). Its subscriber terms grant no ownership of the ads.

Best for

Small teams resizing static banners for Meta and Google Display from one brand kit, within 10 to 50 downloads a month.

Not for

Anyone needing written ownership of outputs without an Enterprise contract, or more than 10 downloads a month on Starter’s base tier.

Back to the tool list

Pencil

Pencil writes copy with its text agent and scores each ad. Core lists $14 a month for 50 generations (Pencil pricing). Users praise one idea turned into many sized variants (10 of 25 sources: G2, YouTube). On Core and Growth, Pencil owns the outputs and licenses them back (terms 3.1, 3.2).

Best for

Brands that want to brief, generate, score and launch static and video ads in one workspace, choosing the model per job.

Not for

Anyone who needs to own outputs outright: on Core and Growth Pencil owns them and grants you a licence. Core’s 50 generations cover about 11 agent-made statics a month at Pencil’s own rates.

Back to the tool list

Omneky

Omneky writes copy with its image and video ads. Lite lists $29 a month for 200 credits, and AI Ad Scoring starts on Standard (Omneky pricing). Users like the speed of variations (12 of 39 sources: Capterra, G2); others call the output generic (10 of 39 sources: Trustpilot, Trustpilot).

Its agreement (4.2) gives Omneky the ads and licenses them to you only “during the Term”, for your own campaigns.

Best for

Brands and agencies that want generation, AI scoring and launching across five ad networks in one account, with credits that roll over.

Not for

Anyone who wants to keep running the ads after cancelling without checking with Omneky first; the terms licence creatives only during the subscription.

Back to the tool list

Predis.ai

Predis.ai writes captions and hashtags with its posts and ads, then schedules them. Core lists $32 a month for 1,300 credits (Predis pricing). Small businesses report hours saved each week (20 of 67 sources: Shopify App Store, Trustpilot). Others report the trial billing the full plan, sometimes a yearly one (11 of 67 sources: Trustpilot, Shopify App Store).

Its terms never mention generated content.

Best for

Small brands and agencies that want one tool to generate, caption and auto-post social content and simple ads across several channels.

Not for

Anyone who needs written ownership of outputs or a refund: the terms never mention generated content, and payments after the 3-day trial are non-refundable.

Back to the tool list

The Brief

The Brief, formerly Creatopy, lists Pro at $39 a month with “Generative AI for text” for copy variations, under the line “no credits. no counters. just plans” (pricing). Long-time users report credits now metering exports and AI actions (13 of 37 sources: Reddit, Trustpilot). Its AI terms allow ad use on every plan.

Best for

Teams designing display and social ads in volume who want AI generation and resizing on a flat fee, from $39 a month on Pro.

Not for

Anyone needing Sora 2 or Veo 3.1 video, Meta and Google Ads publishing or A/B testing on the $39 Pro plan. Those start at Ultra ($99 a month) or Team ($59 a seat).

Back to the tool list

Blaze

Blaze (blaze.ai) writes social posts and emails for small businesses. Starter lists $79 a month for 600 credits and “Automated ad campaigns” (Blaze pricing). Users find the copy generic and repetitive (10 of 48 sources: YouTube, Capterra). Its terms 7(ix)(C) ask for Blaze’s prior written consent before advertising content goes “on or through the Service”.

Best for

Solo founders and small local businesses that want posts and emails generated and scheduled, with Automated ad campaigns listed on the $79 a month Starter card.

Not for

Media buyers who need A/B experiments or per-ad reporting: the plan cards list posting accounts, generation credits and Automated ad campaigns only.

Back to the tool list

Atria

Atria pairs an ad library with an AI strategist that drafts ad concepts and copy. Core lists $129 a month billed yearly and a yearly saving of $360, so monthly billing comes to $159 a month (Atria pricing).

Users credit its research side for briefs (3 of 13 sources: Reddit, YouTube), and others report charges after cancelling (5 of 13 sources: Trustpilot, Trustpilot). No clause in its terms gives you ownership of AI outputs.

Best for

Teams that want competitor research, their own creative reporting and AI concept and copy drafts in one tool, with MCP access for AI assistants.

Not for

Buyers who need written ownership of AI outputs, or small accounts that only need a swipe file (Core is $159 a month on monthly billing).

What Meta’s own text variations do, and where they may run

Meta’s Advantage+ creative is the AI Facebook ad copy generator inside Ads Manager. It writes “up to 5 variations of primary text and headline”, and its help page names no fee (read 26 September 2026).

Meta’s Ad Creative Generative AI Terms (effective 6 May 2024) allow Output “anywhere on Meta Company Products” and add: “Use or publication of Output outside of Meta’s platforms is unauthorized and a violation of these Terms.”

The only place the terms name text is the definition of Input: “Any text, image, video file, document, or other content provided to the Ad Creative AIs”. The terms do not say whether text variations are Output. They also bar presenting Output “as human-generated when it is not”.

One r/FacebookAds poster, who turns it off to avoid “cheesy AI generated ad copy”, says Advantage+ Creative “will NOT toggle off” (thread, 8 September 2026). Best AI tools for Meta ads covers the rest of Meta’s generative features, and the Advantage+ creative guide shows how to turn each feature off.

Who owns the copy, and who trains on it

Six of the 13 tools give you the copy in writing: Claude, ChatGPT, Jasper, Anyword, The Brief and Blaze. Copy.ai’s terms name OpenAI as owner, Pencil owns Core and Growth outputs, and Omneky’s agreement gives the ads to both sides. No clause in the terms of Gemini, AdCreative.ai, Predis.ai or Atria gives you the copy.

Copy.ai’s terms answer the ownership question three times. Section 7(e) licenses Generated Content to you “for your lawful business purposes”, and 7(f) says Copy.AI and its licensors “retain all rights to that content”.

Then 17(a): “Notwithstanding the foregoing, Copy.AI’s licensor, OpenAI LLC, exclusively owns all right, title and interest in and to Generated Content.” OpenAI’s own terms assign Output to the user.

Clauses by plan for every tool here but Atria sit in the AI commercial use matrix.

What the copy scores measure

Anyword, AdCreative.ai and Pencil print an accuracy figure for their score; Omneky prints none. None of the three publishes the ads or the dates behind its figure.

• Anyword’s score grades copy variations “based on their performance and conversion potential” (Data-Driven Editor). Its homepage claims 82% accuracy at picking the better of two variations, against 52% for GPT-5.
• AdCreative.ai gives a Performance Score and an Awareness Score, claims “over 90% accuracy” and links no study (Creative Scoring AI).
• Pencil’s 0 to 100 score “focuses on CTR”. Its blog reports a check on more than 7,000 ads: 61% landed in the right decile band or one away.
• Omneky’s Ad Score averages five sub-scores, from contrast to brand guidelines, with no accuracy figure (help centre).

Tools that test live ads are compared on AI creative testing tools.

Free AI ad copy: what each free plan allows

Claude, ChatGPT and Gemini write ad copy on free plans. The rights matrix rates paid ads on Claude’s and ChatGPT’s free plans allowed with conditions, and on Gemini’s unclear.

Atria’s homepage offers 1,000 free credits, with no ad-use rating. The Brief’s pricing FAQ moves lapsed trials to a Free plan. There, its AI terms let The Brief train its models on your copy and adapt it into templates for other customers.

Jasper, Anyword, AdCreative.ai, Omneky, The Brief and Blaze offer 7-day trials, and Pencil’s free sign-up makes six ads. Predis.ai’s trial runs 3 days and takes a card.

Best AI for ad copy on Reddit: Claude and GPT, and no copy tool

Of 1,873 AI-creative posts in nine subreddits, pulled 23 September 2026, 25 match “ad copy”, “copywrit”, “primary text” or “headline”. By subreddit: r/PPC 11, r/dropship 5, r/marketing 3, r/FacebookAds 3, r/ecommerce 2 and r/shopify 1.

Claude appears in 6 and GPT in 4; no dedicated copy tool on this page appears in any. Posters ask “Best AI for Amazon PPC ad copy?” (r/PPC, 12 May 2026) or describe using ChatGPT and Claude “for grunt work” (r/PPC, 15 June 2026).

Guides and data for ad copy

Every plan above has a dated row in the AI ad tool price tracker. How we check prices and terms sets out the sources behind each row.

Video scripts and voice-overs sit on AI ad script generators and AI voice over for ads, and video hooks on AI hook generators. Labels for AI-made ads are covered in Meta’s AI disclosure rules.

Left out, and why

Adamigo, AdManage, Manus and Google Ads’ own text generation have no row in our price and terms database. Meta Advantage+ creative is described above with no button: it runs inside Ads Manager.
