10 Best AI Hashtag Generators In 2025 [Reviewed]

Are you looking for the best AI hashtag generators to save you time from manually coming up with and writing hashtags for social media posts?

I understand that some of you will be looking for a simple hashtag generator for a one-off social media post, while others will be seeking a more advanced and scalable one (e.g., for handling client work).

In this article, I’ll go over the 10 best AI-powered hashtag generators in 2025, going over both free-to-use and advanced generators for different use cases.

What are the factors to consider when evaluating AI hashtag generators?

Here are the 3 key factors I’d consider in an AI hashtag generator:

#1: Relevance to the original post

The reason why you are looking for a hashtag generator is that you want to brainstorm and come up with the ideal hashtags to use for your social media posts to improve your reach.

This is why the quality and relevance of the hashtags to the original post was the #1 thing I took into consideration when considering the tools in this list.

➡️ This includes how these AI generators used my input to generate hashtags, and if they were providing me with realistic hashtags or just random ones that sound good.

#2: Being able to refine and update your output

Considering that AI rarely gets your desired outcome the first time (especially when it comes to social media), it was important to me to see hashtag generators that let me refine and update the output.

#3: Collaboration capabilities

I also considered more advanced options that can help you collaborate with your team to generate hashtags on different social media accounts in different industries (e.g., if you’re an agency looking for a best-in-class hashtag generator).

What are the 10 best AI hashtag generators in 2025?

Here are the 10 best AI-powered hashtag generators on the market out of the 30+ mini tools I reviewed:

#1: Team-GPT

Team-GPT offers the best place to generate hashtags in the market because it’s possible to customize an AI model to come up with social media hashtags like you would, collaborate with your team, and refine your best prompt with our AI prompt builder.

But if Team-GPT does not have a traditional hashtag generator, what makes it ideal for the job in that case?

➡️ Team-GPT offers 3 things that other generators do not:

• The ability to customize tools like ChatGPT and Claude to produce hashtags like you.
• A prompt builder, which will help you refine your hashtag generation prompt to fit with your content.
• Being able to collaborate with your team on hashtag generation so you can learn from prompts from one another and save your best prompts.

💡 By having better prompts and collaborating with your team, you can produce superior social media posts and hashtags for your clients or your brand in the long run.

Here’s how you can generate hashtags with Team-GPT alongside your team:

Step #1: Build your best hashtag generation prompt with the Prompt Builder

The way our prompt builder works is that you have to begin by describing your task, such as ‘’I’m looking to generate hashtags from a social media post’’ in my case.

After that, our prompt builder will ask you to answer a few follow-up questions about the hashtags that you are looking to generate.

For me, these questions were:

• What is the general topic or theme of the social media post you’re generating hashtags for?
• What kind of tone or style are you aiming for with the hashtags (e.g., humorous, informative, trendy)?
• Which social media platform is this post for (e.g., Instagram, Twitter, TikTok)?

As a final output, Team-GPT generated a prompt to use to generate my hashtags, which provides information about the rules of creating hashtags.

You can learn more about how you can use our prompt builder by watching this guide on it: How to use the Prompt builder | Team-GPT:

Step #2: Click on ‘’Save & Use’’ and Apply the prompt with your content

After you click on ‘’save and use’’, a new form pops up asking you to post your social media post.

Our collaborative AI platform lets you choose the AI model that you want to use for the output, such as ChatGPT-4.1.

💡 Pro Tip: This does not have to be an effort from you alone. You can work alongside your teammates on prompts and save your best prompts.

Here’s the final output that I was provided by Team-GPT after I provided it with my social media post:

Team-GPT provided me with 15 hashtags that:

• Are related to the core topic of ‘’paid returns in e-commerce’’ in my case.
• Include secondary topics, such as shopping smarter and reducing waste.

➡️ If you’re not satisfied with the level of output, you can send a follow-up prompt to refine the text further.

(Optional) Step #3: Add custom instructions to the AI model to come up with hashtags like you

If you’d like to step up your hashtag generation further, you can add custom instructions to ChatGPT or the AI model you prefer to use.

Start by clicking on ‘’Add context’’ on the bottom right of your screen.

From there on, you have to click on ‘Instruction’’ and enter your instruction.

You’ll also notice that you can store these instructions, as I have done for humanizing text and article content creation.

From there on, you can add your custom instructions, including the type of instructions.

Team-GPT Pricing

Unlike the majority of the AI hashtag generators in this guide, there’s no free plan for Team-GPT.

Team-GPT offers three paid plans based on your team size and needs:

• Starter Plan: Starts from $25/user/month (billed annually). Designed for teams adopting AI efficiently, this plan includes a collaborative workspace for marketers and agencies, usage of the latest models by OpenAI and Anthropic, and usage reports.
• Growth Plan: Starts from $35/user/month (billed annually). Built for teams scaling AI with governance, it includes everything in the Starter Plan plus unlimited model usage, Single Sign-On (SSO), advanced usage reports, option to bring your own API keys, integrations, and tailored onboarding.
• Enterprise Plan: Designed for organizations with 150 or more users, with custom pricing. It includes everything in the Growth Plan, plus unlimited workspaces, private cloud deployment, ability to add custom models, premium key account management, and enterprise-ready security measures.
