Beyond AI copy and stock-style image generation
Bertha AI is a WordPress plugin centred on AI copywriting and image generation. The product helps writers produce blog drafts, product descriptions, and marketing copy, with image generation as a complementary surface. For sites whose AI need is concentrated on copy, Bertha is a recognisable fit. SleekAI is a different product shape. It is built around editor-resident chat, agent mode in major page builders, public chatbots trained on site content, and bulk alt-text, with copy generation as one capability among several rather than the headline.
The integration depth is the first divergence. SleekAI's chat sidebar opens inside Bricks, Elementor, Gutenberg, and Oxygen, with field-level help in Meta Box and ACF. Agent mode can call tools to make multi-step edits on a page. Bertha's primary surface is a writing assistant attached to the post editor, with broader integrations available but less prominent.
Public chatbots and bulk alt-text are the second axis. SleekAI's chatbot builder trains on the site's posts and pages, then embeds on the front end with your provider key. Bulk alt-text runs against the media library on demand. Bertha's image generation produces new visuals; SleekAI's alt-text feature instead annotates the images already in your library, which is closer to the typical accessibility and SEO job WordPress sites need done.

Features
Three things that actually change how you work
Chat where you already edit
SleekAI's sidebar chat opens inside WP Admin and inside Bricks, Elementor, Gutenberg, and Oxygen. Drafting copy, rewriting a section, or asking about the current page happens without leaving the editor.
Agent mode with tool calls
Hand the agent a multi-step goal and it can act on the editor through tool calls instead of only emitting text. Bertha's writing surface is template-style; SleekAI's agent is goal-style.
Bulk alt-text for the existing library
Scan the media library and have a vision model write descriptive alt attributes for the images already there. It is the accessibility and SEO job most sites need done, and it complements rather than competes with image generation.
Migration
Switching from Bertha AI is a parallel install
1. Install SleekAI alongside Bertha
Both can run in parallel. Connect SleekAI to your OpenAI, Anthropic, Google, or OpenRouter key and verify the chat sidebar opens in your editor of choice.
2. Move copy work into SleekAI's chat
For new pages and posts, draft inside SleekAI's chat sidebar in Bricks, Elementor, Gutenberg, or Oxygen. The prompts that drove Bertha templates work as natural language requests against the page in front of you.
3. Add chatbots and alt-text
Train a SleekAI chatbot on your posts and pages, embed it on the front end, and run a bulk alt-text pass on the media library. These cover the parts of SleekAI that sit outside Bertha's copy and image scope.
4. Decide what to keep from Bertha
If Bertha's image generation has been part of the workflow, keep it for that or replace it with a dedicated image tool. SleekAI does not generate stock-style imagery; it focuses on text and on alt-text for existing images.
Audience
Who tends to switch from Bertha AI
Builders deep in page builders
Teams whose pages are built in Bricks, Elementor, or Oxygen get more value from chat and agent mode opening inside those builders. SleekAI is shaped around that workflow.
Sites adding a public chatbot
If the AI strategy includes a visitor-facing chatbot trained on the site's own content, Bertha does not target that. SleekAI does, as a first-class surface.
Sites needing alt-text at scale
Bulk alt-text across thousands of media items is a focused job. SleekAI targets it with a vision model and your own provider key, separately from any image generation pipeline.
The bigger picture
Why a broader AI toolkit matters more than another copywriter
Bertha AI's strength is its focus on copy and images. The plugin is honest about being an AI copywriter for WordPress, with a familiar template-style interface and image generation alongside. That covers a real workflow, especially for blog-heavy sites where the daily AI job is producing post drafts.
The trouble starts when the AI need broadens. A public chatbot trained on the site's docs, alt-text across a deep media library, multi-step edits inside a page builder, structured help with ACF or Meta Box fields: those jobs do not fit neatly inside a copywriting tool, and stacking three or four extra plugins on top adds cost and surface area. SleekAI is shaped around that broader job.
Editor chat covers the writing work. Agent mode handles multi-step changes inside Bricks, Elementor, Gutenberg, Oxygen, Meta Box, and ACF. Chatbots are a primary surface.
Alt-text is a focused feature against the existing library. One flat license, one provider key, four jobs done in the same plugin. For sites whose AI ambitions reach past the post body, the consolidation makes the plugin shelf shorter and the bill more predictable.
Questions
Common questions about switching from Bertha AI
For copy work and editor chat, yes, with broader integration into page builders. For AI image generation, SleekAI is not a replacement: it focuses on text features and on alt-text for existing images rather than generating new visuals.
Not as a primary feature. SleekAI is centred on chat, agent mode, chatbots, and alt-text. If image generation is core to your workflow, keep a dedicated tool for that and use SleekAI for the text and accessibility side.
OpenAI, Anthropic, Google Gemini, and OpenRouter. Keys paste into SleekAI's settings and every feature runs through them at API cost with no Sleek-managed billing layer.
Bertha typically sells subscription tiers with managed inference. SleekAI is a flat plugin license plus your own provider account at the provider's published API rate. For steady or growing usage, the flat license usually settles cheaper than subscription credit caps.
Agent mode lets the AI call tools, not only emit text. Goals like 'rewrite this hero into three variants and apply the strongest' run as single requests that the agent executes against the editor in front of you.
Inside WP Admin and inside Bricks, Elementor, Gutenberg, and Oxygen, with field-level help in Meta Box and ACF. Bertha's writing surface is more focused on the post editor.
Yes. The chatbot builder indexes your posts, pages, and documentation, then embeds on the front end. Bertha does not focus on visitor-facing chat.
SleekAI scans the media library, sends each image to a vision-capable model on your provider key, and writes the returned description back to the attachment's alt-text field. Run as a backfill or hook newly uploaded images.
