Questions & Answers

As answered by people managing AssemblyAI and Split Prompt.

What makes your product unique?

Split Prompt's answer:

SplitPrompt stands out by using recursive prompt splitting combined with token-based counting to ensure that the main goal of long prompts is retained throughout the conversation. Instead of just breaking up text based on length, it ensures that key information is restated after each chunk, keeping ChatGPT focused and accurate. This level of precision is unmatched by simpler splitting tools, making it ideal for users who need more control and clarity when working with AI.

Why should a person choose your product over its competitors?

Split Prompt's answer:

A person should choose SplitPrompt because it offers a smarter approach to managing long prompts. While many tools simply break up text by string length, SplitPrompt goes a step further by restating the goal after each chunk, ensuring no important details are lost. Its token-based system provides more accurate splits, and its lightweight, vanilla JavaScript design makes it fast, efficient, and easy to useโ€”perfect for users who want a reliable tool without unnecessary complexity.

How would you describe the primary audience of your product?

Split Prompt's answer:

The primary audience for SplitPrompt includes researchers, creators, developers, and anyone who frequently works with ChatGPT or other AI models that have context limitations. These users often deal with long, complex prompts and need a solution that maintains focus and accuracy without sacrificing efficiency.

What's the story behind your product?

Split Prompt's answer:

SplitPrompt was born out of a personal frustration with ChatGPTโ€™s context window limitations, which often caused the AI to lose track of long prompts. While exploring ways to overcome this, the idea of recursive prompt splitting emerged as a solution to break up large prompts while ensuring the main goal stayed clear. By incorporating token-based counting and goal restating, SplitPrompt evolved into a tool that helps users interact with AI more effectively. It was built with simplicity in mind, using vanilla JavaScript, and is freely hosted on GitHub Pages.

Which are the primary technologies used for building your product?

Split Prompt's answer:

SplitPrompt is built using vanilla JavaScript for the core logic and GitHub Pages for hosting. Token-based counting ensures more accurate splits, and recursive logic drives the goal restating feature. Itโ€™s designed to be lightweight, fast, and easy to use, leveraging minimal dependencies to maximize performance.

  • How Machines Hear and Understand Us
    Itโ€™s about valueโ€”saving time, money, and effort. Traditional transcription services charged $1-2 per audio minute. Imagine needing 10 hours transcribedโ€”thatโ€™s $600 to $1,200, just to get your words on paper. With tools like Assembly AI charging $0.015 per minute (thatโ€™s $0.90 for an hour), the cost drops dramatically. For companies dealing with large volumes of audio, this is a game changer. - Source: dev.to / over 1 year ago

    The auto caption is from assemblyai.com, they do a pretty good job. As for manual, you can do `Add Layer` > `Text` from the short-form editor then trim each text layer. Its slow going though. Ideally we will figure out a better interface and build it. For now I recommend using the auto caption, then modifying it to your liking, if there is more than a few words it will probably be faster. Thanks for the kind words! Source: over 3 years ago
