AI Instagram Caption Tools Comparison: Features and Pricing
7 Best AI Tools to Instantly Generate Instagram Captions
1. Hootsuite
Hootsuite provides two AI-driven tools for captions: a free web-based generator and OwlyWriter AI/OwlyGPT, available to subscribers. The paid version incorporates Talkwalker's real-time social listening to enhance its functionality.
Caption Creation Features
Hootsuite uses established copywriting frameworks - like AIDA, PAS, HOOK, and WIIFM - to craft captions tailored to your audience in five different languages. While Instagram allows captions up to 2,200 characters, Hootsuite suggests keeping them between 138 and 150 characters for better engagement.
To generate captions, simply provide a brief description, select Instagram as your platform, and include keywords to improve SEO.
Hashtag Suggestions and Posting Insights
OwlyGPT comes with an AI-powered hashtag generator that examines your caption text and uploaded images to recommend suitable tags. Additionally, the "Best Time to Post" feature analyzes your audience data to help you schedule posts at the most effective times.
Adapting to Your Brand Voice
OwlyGPT adapts to your brand's voice by analyzing your previous posts and bio. You can also choose from various tones through a dropdown menu to ensure the captions align with your brand's personality. Angela Ferdinando, Social Media and Brand Marketing Manager, shares:
Hootsuite's AI tools and hashtag generation capabilities make content creation and scheduling fast and seamless.
Hootsuite’s pricing and accessibility add even more appeal for content creators.
Pricing and Accessibility
The free AI caption generator is available without requiring a signup or credit card. For subscribers, OwlyWriter AI and OwlyGPT are included in all Hootsuite plans, which start at $99/month (billed annually) for one user and up to 10 accounts. New users can also take advantage of a 30-day free trial. Plus, the AI integrates with approval workflows, allowing for a final review before publishing.
2. Planable
Planable leverages machine learning and natural language processing to create up to five caption variations from a single input. This gives users a variety of caption styles to suit different types of posts.
Caption Generation Capabilities
What sets Planable apart is its ability to generate multiple caption options while allowing users to fine-tune the tone to align with their brand. You can choose from post intents like Actionable, Inspiring, Introspective, or Promotional to craft content that fits your goals. The tool also offers two length options: "Shorter" for concise messages and "Longer" for more detailed narratives. While Instagram allows up to 2,200 characters per caption, Planable highlights that captions around 125 characters tend to perform best in terms of engagement. For brands looking to connect with their audience, an "Actionable" tone can be particularly effective in driving interaction and attracting the right followers.
Hashtag Optimization Features
Planable includes an AI-powered hashtag generator designed to suggest relevant tags based on your chosen style. Users can generate hashtags in batches of 5, 10, or 30, formatted as either a list or a single line. To keep posts visually clean, hashtags can be placed in the first comment. Although Instagram permits up to 30 hashtags per post, Planable recommends using 5–10 well-targeted hashtags to strike a balance between reach and aesthetics.
Customization Options for Brand Voice
Planable offers extensive customization options to help brands maintain a consistent voice. With 10 distinct writing styles - such as Humorous, Inspirational, Informative, Formal, and Witty - users can adapt captions to fit their unique identity. Miruna Dragomir, CMO at Planable, emphasizes this point:
"In the wild world of social media, a strong, consistent brand voice is your best defense against the dreaded scroll-past syndrome".
Additional features like emoji and hashtag toggles allow users to inject personality into their captions while saving up to 33% of planning time. Together, these tools ensure that your posts not only stand out but also align seamlessly with your brand's messaging.
Pricing and Accessibility
Planable’s AI Instagram Caption Generator is entirely free and doesn’t require users to sign up.

The stats speak for themselves: 85% of businesses have reported improved productivity thanks to AI-driven content creation, while 61% of marketers have seen a boost in social media engagement through AI-generated content.
However, finding the right balance is key. As Alyssa English from Originality.ai explains:
AI is best as a tool to assist with social media caption creation rather than a full-scale solution to manage caption writing or other social media processes.
Let AI handle tasks like keyword research, hashtag suggestions, or drafting initial captions. Then, step in to add your personal touch and creativity. This approach not only saves time but also allows you to focus on refining your broader content strategy.
