Best AI Tools for Marketing You Should Know in 2025

When it comes to AI tools for marketing, one question always comes up: which one is the best? You might already be using one of the free versions out there, or maybe you’ve wondered whether it’s worth upgrading to a paid plan.

At Viral Omega, as a digital marketing agency working with multiple platforms and campaigns, we wanted to put that question to the test. Here’s the fact: there’s no such thing as one single best AI tool.

The smartest move you can make is investing in the AI platform you’ll actually use every day for your marketing workflows. We’ll share our honest thoughts on each one: ChatGPT, Google Gemini, Perplexity, and Claude.

1. ChatGPT

First is ChatGPT, one of the earliest and most widely known AI tools for marketing. It’s had quite a few upgrades recently, offering multiple models like 4o, 03, and 04-mini.

Where ChatGPT Works Best for Marketing

Marketers can rely on ChatGPT for:

• Writing marketing emails
• Brainstorming campaign ideas
• Building out ad copy or social captions
• Handling basic analytics and data breakdowns
• File uploads such as PDFs, images, and spreadsheets to support content planning

They’ve also introduced some great new features that make AI tools for marketing and automation accessible, even for teams without heavy tech skills:

• The 03 model can now schedule tasks based on what it remembers about you.
• It can prep weekly competitor analysis reports or send AI marketing trend updates to your inbox every morning.
• The new 4o image generator improves visual content creation for social posts, blog thumbnails, and ads.
• You can even create custom GPTs for niche marketing tasks like SEO audits, content calendars, or campaign briefs.

Limitations

A few things to note:

• In long strategy sessions or content planning chats, it tends to forget earlier parts of the conversation.
• Occasionally, it hallucinates information, so fact-checking is necessary — especially when accuracy matters in marketing decisions.
• Its deep research feature is good but pulls fewer sources compared to tools like Gemini or Perplexity.

When to Upgrade to ChatGPT Plus

An upgrade makes sense if:

• You want a marketing tool that handles a variety of daily content and campaign tasks
• You need high-quality image generation for social, ads, and blog banners
• You plan to automate reporting or marketing updates using the scheduling and memory features
• You require unlimited access to all models without hitting usage limits

2. Google Gemini

Next is Google Gemini. It’s ideal for content creation, campaign research, analytics reporting, and competitive analysis.

Why Gemini Is a Strong Marketing Asset

With the launch of the 2.5 Pro and Flash models, Gemini has become one of the most powerful AI tools for marketing and data analysis. The deep research feature within the 2.5 Pro model is excellent. It’s in-depth, thorough, and reads like a professional market research report.

Additional highlights for marketers:

• A massive 1 million token context window for handling complex briefs, data reports, and strategy documents
• Real-time web searches to track marketing trends, audience insights, or competitor activity
• Seamless integration with Google Workspace apps like Gmail, Docs, and Sheets
• New features like short video generation for ads and social reels, plus image creation inside Gemini for content assets

Limitations

A few things to keep in mind:

• The writing style can feel formal or academic. Less suited for casual social copy or influencer-style captions.
• I usually need to prompt it to write in a relaxed, brand-friendly voice.
• It’s perfect for proposals, campaign reports, and technical marketing documents, but less ideal for light creative copy.

When to Upgrade to Gemini Advanced

Consider upgrading if:

• You manage large campaign documents, marketing audits, or strategic plans
• You’re embedded in Google’s ecosystem for email marketing, Docs, and content approvals
• You want an AI tool that can track real-time marketing trends or run in-depth campaign analysis
• You value marketing automation and deep integrations with Google’s cloud apps

The $19.99 per month plan, bundled with 2TB of storage, is excellent value for marketing agencies and freelancers alike.

3. Perplexity

If you value fast, accurate, real-time answers, Perplexity should be your go-to for campaign research and digital strategy work.

Why Perplexity is Great for Marketing

This tool’s strength lies in its ability to search the web in real time and deliver concise, reliable answers with clear sources

• Rapid market research
• Competitor monitoring
• Fact-checking marketing stats and trends
• Quick copy ideas for ad headlines, social posts, or product descriptions
• Sourcing fresh blog or campaign angles

Perplexity also features a ‘Discover’ dashboard to stay updated on marketing news, AI trends, and consumer reports.

It lets you pick the source types too:

• Web for general internet results
• Academic for white papers or in-depth reports
• Social for audience sentiment insights (primarily pulling from Reddit)

You can even upload client PDFs or creative briefs for AI analysis, making it a versatile marketing research assistant.

Where It Falls Short for Marketing Use

However, it’s less useful for:

• Purely creative writing or content brainstorming
• Long, ongoing marketing strategy conversations
• Image generation (the current tool uses an older DALL·E 3 model)

When to Upgrade to Perplexity Pro

The Pro plan at $20 a month, is worth it if:

• You need a fast, reliable AI research assistant
• You frequently fact-check campaign stats or product claims
• You run competitor analysis or content audits
• You want neatly sourced market insights, trend breakdowns, and references

4. Claude

Finally, Claude — the AI tool I use least often, but one that deserves attention for its creative and content-focused strengths.

Why Marketers Should Consider Claude

Claude feels more like brainstorming with a real creative partner than most AI tools. Its conversational style makes it ideal for:

• Campaign brainstorming
• Blog writing
• Social media captions
• YouTube scripts
• Strategic messaging development

Key features for marketers:

• A 200,000 token context window for handling complex content plans
• The capacity to work with PDFs, Word docs, Excel files, and images
• A Projects feature for organizing content research and strategy notes under one topic
• A prompt library designed for brainstorming, content ideation, and strategy prompts

Limitations for Marketing Use

Until recently, it lacked real-time search, which meant it was sometimes outdated for fast-moving marketing trends. That’s now fixed.
However:

• It doesn’t offer image generation
• The Pro plan limits messages to 45 every 5 hours, which may matter for busy teams

When to Upgrade to Claude Pro

It’s worth the $20 upgrade if:

• You frequently brainstorm campaign ideas or marketing messages
• You want a more human-like, casual writing style
• You need organized project files for campaigns or clients
• You handle large campaign reports or multiple content drafts
