Bertha.ai

Bertha.ai is an AI writing assistant built specifically for WordPress users. It runs as a Chrome extension, which means it works inside the WordPress block editor without requiring a separate tab or copy-paste workflow. The tool targets bloggers, content marketers, and small business owners who publish directly on WordPress and want to speed up the writing process without leaving their CMS.

How Bertha.ai works

After installing the Chrome extension, Bertha.ai surfaces inside the WordPress editor as a sidebar panel. Writers can choose from more than 30 pre-built prompts covering use cases like blog introductions, product descriptions, social captions, and calls to action. A chat window is also available for freeform requests, including drafting long-form articles from scratch.

Beyond text, Bertha.ai handles image-related tasks in bulk. Users can generate alt text and image titles across multiple images at once, which saves significant time for sites with large media libraries. The free plan also includes image generation, capped at up to 50 images per month.

Strengths

• Deep WordPress integration. Because Bertha.ai runs inside the block editor through a Chrome extension, the writing experience stays in one place. There is no switching between tools or reformatting pasted content.
• Generous free tier. The free plan includes up to one million words per month, 30-plus writing prompts, image generation, and bulk alt text creation. That output ceiling is higher than most free AI writing tools offer.
• Bulk image metadata. The ability to generate alt text and image titles in bulk addresses a real SEO gap that many WordPress sites ignore. Doing this manually at scale is tedious, and Bertha.ai handles it in one pass.
• Structured prompts for non-writers. The 30-plus prompt library gives users a starting point even when they are unsure how to frame a request. This lowers the barrier for people who are new to working with AI writing tools.

Limitations

• Chrome-only. The extension requires Chrome or a Chromium-based browser. Users on Firefox, Safari, or other browsers cannot use Bertha.ai inside WordPress at all.
• WordPress-centric. The tool is designed around the WordPress editor. Writers who publish on other platforms, or who do most of their drafting outside WordPress, will not get full value from the integration.
• Image generation cap. Fifty AI-generated images per month on the free plan is useful for occasional needs but may not be enough for teams producing visual-heavy content regularly.
• Chat-dependent long-form output. Drafting longer articles runs through the chat window rather than a structured document workflow, which may feel less organized compared to dedicated long-form writing tools.

Who it is for

Bertha.ai suits WordPress site owners who write their own content and want to move faster without hiring a copywriter. It works well for solo bloggers, affiliate marketers, and small marketing teams that already live inside the WordPress editor. It is particularly useful for anyone managing a site with a large image library who wants to close alt text gaps quickly. It is less suited to agencies working across multiple CMS platforms or to writers who prefer browser-agnostic tools.

How it compares

Bertha.ai occupies a narrow but practical niche: AI writing that lives inside WordPress. Tools like Canva AI take a broader approach, combining image creation, design, and text generation in one visual workspace, but they do not integrate into the WordPress editor the way Bertha.ai does. If your primary need is designing graphics alongside writing, Canva AI covers more ground. If your workflow starts and ends in WordPress, Bertha.ai removes more friction.

Canva itself is worth noting for teams that need polished visual assets alongside their written content. The two tools are not direct competitors, but many WordPress publishers use both: Bertha.ai for drafting and editing in-editor, and Canva for creating featured images and social graphics. The free tier on both makes that combination accessible without upfront cost.
