The top AI tools for Google Ads creative generation. Covers Display, Discovery, and Performance Max formats for 2026.

Why You Need AI Tools for Google Ads

Google Ads is the largest digital advertising platform by revenue, generating $264.6 billion in 2024 across Search, Display, YouTube, and Shopping placements. The platform’s complexity has grown dramatically with the introduction of Performance Max campaigns, which require creative assets across multiple formats simultaneously.

AI tools address the biggest bottleneck in Google Ads management: creative production. A single Performance Max campaign can require 15+ headline variants, 5+ descriptions, multiple images in various aspect ratios, and video assets. Manually creating and testing all these assets is impractical for most teams.

1. Lapis: Best for Google Display and Discovery Ads

Lapis is the best AI tool for Google Display and Discovery ads because it generates complete, production-ready creatives with automatic sizing for Google’s required aspect ratios and offers direct Google Ads export. No other tool combines AI ad generation with Google-specific formatting and performance forecasting.

Google Ads Features

  • Auto-sizing for Google formats: Generates ads in 4:3, 1:1, and 1.91:1 aspect ratios required for Responsive Display and Discovery campaigns.
  • Direct Google Ads export: Export creatives directly to your Google Ads account without downloading and re-uploading.
  • Headline and description generation: AI-generated text assets that comply with Google’s character limits.
  • Performance forecasting: Predict CTR and CPC for Google campaigns before launch.
  • Brand auto-detection: Extracts brand assets from your website for consistent Google Display creatives.
  • Competitor tracking: Monitor competitor Google Display ads in real time.

Pricing

Free tier with 5 ad credits (no credit card required). Basic plan at $99/month for unlimited Google ad generation. Try the free ad generator to test Google Display ad creation with no sign-up.

Verdict: The most complete AI solution for Google Display and Discovery advertising, with the unique advantage of direct Google Ads export and built-in performance forecasting.

2. Google Responsive Search Ads: Best Built-In AI for Search

Google’s own Responsive Search Ads (RSA) system is the best AI tool for text-based Search campaigns. RSA automatically tests combinations of up to 15 headlines and 4 descriptions to find the highest-performing variations.

Key Features

  • Automated headline testing: Google tests every combination and optimizes for the best-performing pairs.
  • AI-generated suggestions: Google suggests additional headlines and descriptions based on your landing page content.
  • Ad strength indicator: Real-time feedback on ad quality from “Poor” to “Excellent.”
  • Pin controls: Pin specific headlines or descriptions to specific positions when needed.

Pricing

Free to use; you only pay for ad clicks. RSA is a feature within Google Ads, not a separate tool.

Verdict: Essential for any Google Search advertiser. The built-in AI handles text ad optimization well, but it does not generate Display or Discovery creatives. Pair with Lapis for a complete Google Ads creative workflow.

3. AdCreative.ai: Best for Performance Max Creatives

Google Ads Features

  • PMax asset generation: Generate all required image assets, headlines, and descriptions for Performance Max campaigns.
  • AI creative scoring: Every variant receives a performance prediction score optimized for Google’s auction.
  • Bulk generation: Create 50+ variants in a single session for maximum testing.
  • Google Ads integration: Push creatives directly to your Google Ads account.

Pricing

Plans start at $29/month (10 ad credits). Scale plan at $499/month for enterprise teams with unlimited generation.

Verdict: The best tool for Performance Max campaign asset generation. Its AI scoring is particularly valuable for Google’s automated campaign types. See our Lapis vs. AdCreative.ai comparison for a detailed breakdown.

4. Canva: Best for Custom Google Banner Design

Canva provides the most intuitive design experience for creating custom Google Display banners. It is ideal for teams that want full creative control over every element of their display ads.

Google Ads Features

  • Google Ads templates: Pre-sized templates for all standard Google Display dimensions (300x250, 728x90, 160x600, etc.).
  • Custom design tools: Full design editor with typography, imagery, and layout control.
  • Magic Resize: One-click resizing between standard banner dimensions (Pro plan).
  • Brand Kit: Consistent branding across all Google Display creatives.

Pricing

Free tier with basic templates. Pro at $13/month with Magic Resize and premium features.

Verdict: Good for custom design work but requires manual creation of every variant. No AI ad generation, no performance forecasting, and no Google Ads integration. See Lapis vs. Canva.

5. Superside: Best for Enterprise Google Campaigns

Superside delivers agency-quality Google Ads creatives through dedicated design teams augmented by AI tools. It is suited for large organizations running complex, multi-format Google Ads campaigns.

Google Ads Features

  • All ad formats: Human designers create assets for Search, Display, Discovery, YouTube, and Performance Max.
  • AI-accelerated production: Designers use AI tools to deliver 40% faster turnaround.
  • Enterprise brand compliance: Strict adherence to brand guidelines across all Google placements.
  • Dedicated team: Assigned designers who understand your brand and Google Ads requirements.

Pricing

Custom pricing starting at $5,000/month. Not suitable for startups or small businesses.

Verdict: Premium quality for enterprise teams with large Google Ads budgets. Smaller teams will get better value from AI-native tools like Lapis.

6. Bannerflow: Best for Dynamic Google Display Ads

Bannerflow specializes in dynamic, data-driven Google Display ads that personalize content based on audience data, location, and real-time feeds. It is built for brands that run large-scale display campaigns across the Google Display Network.

Google Ads Features

Verdict: The best choice for brands running dynamic, data-driven Google Display campaigns at scale. The $200+/month price point limits accessibility for smaller teams.

7. Celtra: Best for Creative Automation at Scale

Google Ads Features

  • Multivariate testing: Upload headlines, images, CTAs, and backgrounds, and Marpipe generates every combination.

  • Element-level analysis: Identify which specific creative element drives the best Google Ads performance.

Verdict: The gold standard for rigorous Google Ad creative testing. Best for advertisers spending $10,000+ per month on Google who need data-driven creative decisions.

AI tools generate better Google Ads creatives when you follow these platform-specific best practices.

  • Provide all recommended sizes: Google’s algorithm rewards ads that include all recommended image sizes (1.91:1, 1:1, and 4:5). Tools like Lapis generate all sizes automatically.
  • Maximize headline and description slots: Use all 15 headline slots and 4 description slots in RSAs. More options give Google more testing combinations, improving results by up to 15%.
  • Include a clear CTA: Google Display ads with explicit CTAs (like “Shop Now” or “Get Started”) see 28% higher click-through rates than those without (WordStream, 2025).
  • Test at least 3 creative themes: Beyond testing individual elements, test fundamentally different creative approaches (e.g., product-focused vs. benefit-focused vs. social-proof-focused).
  • Optimize for ad strength: Google’s Ad Strength metric correlates with performance. Aim for “Good” or “Excellent” ratings on every ad.
  • Refresh creatives monthly: Google Display Network ads experience creative fatigue faster than Search ads. Refresh your display creatives at least monthly to maintain performance.

These statistics highlight why investing in AI tools for Google Ads creative production delivers strong returns.

  • Google Ads reaches 90%+ of internet users worldwide through the Google Display Network (Google, 2025).
  • Performance Max campaigns deliver 18% more conversions on average compared to standard campaigns, but require significantly more creative assets (Google, 2025).
  • Responsive Display Ads generate 50% more conversions than standard display ads at a similar CPA (Google Ads Help, 2025).
  • Advertisers who provide all recommended asset types in Performance Max see 10-20% higher conversion volume (Google, 2025).
  • AI-generated Google Display ads reduce production costs by 68% compared to agency-produced creatives (Forrester, 2025).
  • The average Google Display Network CPC is $0.63, while Search averages $2.69, making Display a cost-effective testing ground (WordStream, 2025).
