24 alternatives to GPT Prompt IDE

Hi HN, Today we're launching a tool to help you evaluate and test prompts for Generative AI. We have been building different GPT3 apps and noticed a gap in tooling to help developers assess the quality of different prompts. Our tool helps you template and test on different datasets and LLM models like GPT-3, GPT-3.5 and open source models like flan-t5-xxl. We are just getting started and would be delighted to receive your feedback.

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. GPT Prompt IDE launched in 2023; newer entries below may have overtaken it.

    PromptForge: Open-source AI prompt engineering workbench with systematic evaluation I built PromptForge after getting frustrated with the manual trial-and-error approach to prompt engineering. Most tools are just text editors, but I wanted something that brings software engineering discipline to prompt development. Key technical features: - AI-assisted prompt generation (stop starting from scratch) - Systematic evaluation engine that auto-generates test suites - Multi-model support (Claude, GPT-4, Azure OpenAI) - Go backend with SQLite for performance and simplicity - One-line Docker…

    Hi HN, I've been working on an experimental tool that helps you use GPT to work on your codebase. I'd love to improve the tool if there's interest. New ideas welcome! I think this could also be useful for experimenting with other types of recursive prompts. It’s a little bit Swiss Army knife and a little bit skynet: https://github.com/ferrislucas/promptr From the README: Promptr is a CLI tool for operating on your codebase using GPT. Promptr dynamically includes one or more files into your GPT prompts, and it can optionally parse and apply the changes that GPT suggests to…

    Hey HN! I’m Zach one of the co-founders of Adam (https://www.adamcad.com). We're building AI-powered tools for CAD and 3D modeling [1]. We’ve recently been exploring a new way to bring GPT-style image editing directly into 3D model generation and are excited to showcase this in our web-app today. We’re calling it creative mode and are intrigued by the fun use cases this could create by making 3D generation more conversational! For example you can put a prompt in such as “an elephant” then follow it up by “have it ride a skateboard” and it preserves the context, identity and…

    One of the coolest things I've been able to get GPT-3 to do is generate questions based on a piece of text. So, I built a simple site to help others do the same. Hopefully, this can be useful to teachers, trainers, or just anyone who wants to create a fun and unique quiz.

    After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live. As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor. This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And…

    Spelltest framework simulates conversations between AI ‘synthetic users' in an environment to test and refine LLM-based applications. It ensures your app converse with utmost accuracy and relevance. Post-chat, Spelltest assesses responses, providing qualitative and quantitative feedback on performance. Suitable for both chat and completion modes. When to use: - After modifying your prompt. - When your LLM provider updates. - As a CI step for you repo. All feedback and collaborations appreciated!

    Hi HN, I recently built PromptForge — a minimal, developer-first web app that helps you generate high-quality GPT prompts from just a few structured fields. Why? As a developer, I often found myself rewriting similar prompts manually. I wanted a faster and more reliable way to generate optimized prompts for various tasks — coding, debugging, idea generation, etc. So I built a tool that combines structure, speed, and simplicity. What it does: Select a use case (e.g. summarization, code explanation) Fill out a few fields (context, tone, output format) Get a clean, optimized prompt Save, reuse,…

    I had 2 weeks off from work and wanted a pet project before heading back. With GPT and Generative AI in the news, I decided to chain multiple Al products together to build something really cool. I set my end goal to be: prompt-to-storyboard (aka fun videos generated purely via generative AI). There exists some prompt-to-video products, but I wanted to tell stories with audio as well. The end product takes an initial prompt and produces a series of images and audio files, which I then combine (with subtitles) into the final video. To showcase videos, there is a basic upvote/downvote…
