AI ad script generators

Script writers and script-to-video tools, one by one

Three kinds of tool write ad scripts. General assistants write from whatever you paste. Jasper and Atria write inside a marketing workspace. Video tools draft the script next to the actor who speaks it, or only read the script you bring.

Claude: scripts from your own reviews

Claude’s Free plan writes scripts from the customer reviews and briefs you paste in; Pro costs $20 a month (Claude pricing). Users pick it for hooks and ad angles (8 of 44 sources: r/FacebookAds, YouTube). Usage caps are the top complaint, on paid plans as well (11 of 44: Trustpilot, Trustpilot).

Best for

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

Skip it if

you want the script and the video from one tool: Claude makes no images or video, so the actor tool comes second.

ChatGPT: a script and its still in one chat

ChatGPT writes the script and generates a matching still in the same chat. Plans and prices: ChatGPT profile. Its sharing policy asks you to mark AI content “in a way no user could reasonably miss or misunderstand” (rights row).

Best for

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

Skip it if

you need a published usage quota: the plans say “limited”, “more” or “unlimited” and print no number.

Gemini: free scripts next to Nano Banana images

Gemini’s free plan writes scripts and makes images; Google AI Plus is $4.99 a month (Google AI plans). Users report hallucinated facts that need checking before anything ships (8 of 38: Trustpilot, Trustpilot). Ad use of output is unclear: Google’s terms say only that it “won’t claim ownership” (rights row).

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.

Skip it if

a product claim in the script rests on figures the model supplies: users report confident errors in facts and numbers.

Jasper: scripts in a shared brand voice

Jasper’s Pro plan costs $69 a month a seat, with 2 Brand Voices and 5 Knowledge assets, after a 7-day trial (Jasper pricing). Brand voice is its most praised feature (8 of 44: YouTube, G2). Billing leads the complaints: trials that convert to annual charges and refused refunds (13 of 44: YouTube, Trustpilot).

Best for

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

Skip it if

you write alone: a general assistant covers hooks and scripts, and Jasper’s terms (5(b)) give no refund on cancellation.

Atria: scripts from competitor ads

Atria pairs an ad library with an AI strategist that writes concepts and scripts (Atria profile). Core costs $159 a month, and the free plan starts with 1,000 credits (Atria pricing). The research side draws the praise (3 of 13: r/FacebookAds, G2); charges after cancelling draw the most complaints (5 of 13: Trustpilot, Trustpilot).

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.

Skip it if

you need to know what one script costs: the pricing page publishes no credit cost per AI action.

Creatify: scripts drafted from a URL or a competitor ad

Creatify’s URL-to-video writes the script and renders the ad together. Its Ad Clone page says the feature “generates original scripts and videos for your brand” from an uploaded ad, “yours or a competitor’s”. Starter costs $39 a month (Creatify pricing). Users report credits running out faster than the pricing suggests (15 of 61: Trustpilot, r/FacebookAds).

Best for

E-commerce teams making URL-to-video ads in volume who want an ad launcher for Meta, TikTok and AppLovin in the same tool.

Skip it if

you want to edit the script without paying again: anything that re-runs the AI counts as a new generation (pricing FAQ).

invideo AI: script to edited video

invideo AI turns a prompt into a script, voiceover, stock footage and captions; users single that out (7 of 42: App Store, Trustpilot). Starter costs $20 a month (invideo pricing). Every regeneration costs credits, fixes included (9 of 42: Trustpilot, Trustpilot).

Best for

Marketers who want a finished, edited video with stock, voice and generated shots in one tool, plus terms that rule out training on their data.

Skip it if

you rewrite scripts many times: each regeneration spends credits, and invideo may change credit costs “at any time, without prior notice”.

Arcads: reads your script with a stock actor

Arcads reads the script you bring with one of 1,000+ AI actors and publishes no price (prices). Its terms (13.3.1) ban “deceptive advertising”, and 13.3.2 sets an indemnity of 500,000 euros per unauthorised use of a video or actor. Users report output below the quality of Arcads’ own ads (18 of 64: Trustpilot, r/FacebookAds).

Best for

Talking-actor ads close to a whole minute long, if billing rounds up to the minute as the help centre’s one example suggests.

Skip it if

your script has the actor claim to be a customer: 13.3.1 bans deceptive advertising.

MakeUGC: reads your script, bars made-up testimonials

MakeUGC voices your script with 1,000+ AI creators. Start up costs $59 a month (MakeUGC pricing), and the credit cost per video is not published. Charges after cancelling lead the complaints (17 of 29: Trustpilot, Trustpilot).

Best for

Direct-response teams testing many UGC and B-roll variants, with Batch Mode from Growth and product-in-hand video from Pro or an API plan.

Skip it if

your script is a customer testimonial: the Fair Use Policy (section 7) forbids using outputs to “fabricate testimonials”.

Captions: prompt to a talking video

Captions turns a prompt into a talking video with a Mirage actor; Max costs $24.99 a month (Captions pricing). Every generation costs credits, failed runs included (8 of 36: Trustpilot, Trustpilot).

Best for

Business teams making avatar ads on Captions on web, whose terms name advertising, and phone creators captioning and editing their own footage.

Skip it if

the script says things you would not say yourself: Mirage’s policy bars input with claims that do not reflect your honest views.

Free AI ad script generators

Claude Free, Gemini’s free plan and ChatGPT Free write scripts at no cost, and Atria starts with 1,000 free credits. The rights rows set the catch. Claude’s and ChatGPT’s free plans allow paid ads with conditions (Claude, ChatGPT); Gemini’s is unclear.

The plan that voices the script matters more than the one that writes it. Creatify’s free video plan is unclear on ads and watermarks every export (free AI UGC generators).

The script lines AI actor tools bar

Four of these clauses address what an AI actor claims; Synthesia’s bars stock avatars from paid social ads. Each row links its line in the rights matrix.

MakeUGC’s own policy says it generates “avatar-led testimonials” (section 1) before section 7 forbids fabricated ones. Synthesia goes further for stock avatars: its help centre says they cannot endorse products at all.

The FTC’s rule (16 CFR 465.1(f)) defines a consumer testimonial as a message “that consumers are likely to believe reflects the opinions, beliefs, or experiences of a consumer who has purchased, used, or otherwise had experience with a product”.

Section 465.2(a) bars a business from writing or creating one that “materially misrepresents, expressly or by implication” whether the testimonialist exists or used the product.

The rule took effect on 21 October 2024 (Federal Register). The AI UGC legal guide sets out who it reaches.

How a script line reads when an AI actor speaks it

One product, four kinds of line. Each meets a different clause.

• Presenter voice (“Here is what the serum contains”). Nobody in the line claims to have used the product. Arcads’ 13.3.1 and the platforms’ own claim rules apply to what it says.
• Customer voice (“As a mum of two, I needed this”). 465.1(f) turns on whether viewers are likely to believe the message reflects a customer’s experience. Synthesia’s help centre bars stock avatars from endorsing at all.
• A claim of experience (“I’ve used it for three weeks”). 465.2(a) names misrepresenting whether the testimonialist exists or used the product. MakeUGC’s section 7 names fabricated testimonials, and the Mirage AUP names claims beyond your honest experience.
• A product claim (“Clears acne in seven days”). The deceptive-ad bans cover it, whoever speaks: Arcads 13.3.1, MakeUGC’s terms 5(b) and its Fair Use Policy.

AI UGC meaning covers the two kinds of AI actor these lines apply to.

TikTok and commercial scripts

The tools above write TikTok and broadcast-style scripts the same way; the platform changes the label. TikTok’s ads policy asks for one on ads whose media is completely AI-generated or significantly modified by AI. An AI actor reading your script sits inside its first example (TikTok AI label guide).

Left out, and why

CapCut’s script generator, the ScriptLab Shopify app, originality.ai, Taskade and Texta write ad scripts too. Their prices and terms sit outside this list; the ad copy hub lists every copy tool we cover.
