CubieAI is Live – AI Tools Built for Creators

CubieAI is live at cubieai.com. It is the third product we have shipped under Cubie Technologies, and the first one built entirely around generative AI.

The idea came from a problem we kept hearing about. People were spending more time writing the caption than making the thing they wanted to post. Editing a video takes an hour; staring at an empty caption box takes another twenty minutes. That second part is the part a machine can help with.

What it does today

The first tool on CubieAI is a caption and hashtag generator. You describe your post in a sentence or two, choose the platform and the tone, and it returns caption options along with hashtags that match the topic rather than a generic popular list.

• Caption generation tuned separately for Instagram and TikTok, because what reads well on one falls flat on the other
• Hashtag suggestions derived from the content of your post, not copy-pasted from a trending table
• Tone control so the same idea can come out casual, professional, or playful
• No account required for the free tools

How it is built

The frontend is plain HTML, CSS and JavaScript — deliberately. A tool this small does not need a framework, and skipping one keeps the page fast on a slow connection, which matters more than it gets credit for.

The backend is a Node and Express service running on a separate subdomain, which talks to the model provider and never exposes a key to the browser. Splitting the API onto its own host means we can change the model or add rate limiting without redeploying the site.

Ship the smallest version that is genuinely useful, then let real usage decide what gets built next.

What is next

The caption generator is the starting point, not the plan. The tools we are looking at next are the ones people have already asked for: rewriting a caption to a different length, generating a short video script from a topic, and turning one post into a set of variations for different platforms.

If you try it and something is missing, tell us. The roadmap for CubieAI is going to be shaped much more by what people actually use than by what looks good on a slide.
