ChatGPT

OpenAI

ChatGPT is an AI-powered assistant designed to help users get answers, generate ideas, and complete tasks more efficiently. It supports a wide range of activities, including writing, brainstorming, coding, and research. Users can interact with ChatGPT through text or voice, making it flexible for different use cases. The platform can summarize information, analyze data, and provide insights to improve productivity. It also assists with creative tasks such as content creation, planning, and problem-solving. ChatGPT includes workspace agents that can automate workflows, handle repetitive tasks, and operate across tools. These agents can run tasks independently, such as generating reports or managing processes on a schedule. Overall, ChatGPT serves as a versatile tool for both personal and professional use.

ChatGPT Plus

OpenAI

We’ve trained a model called ChatGPT which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests. ChatGPT is a sibling model to InstructGPT, which is trained to follow an instruction in a prompt and provide a detailed response. ChatGPT Plus is a subscription plan for ChatGPT a conversational AI. ChatGPT Plus costs $20/month, and subscribers will receive a number of benefits: - General access to ChatGPT, even during peak times - Faster response times - GPT-4 access - ChatGPT plugins - Web-browsing with ChatGPT - Priority access to new features and improvements ChatGPT Plus is available to customers in the United States, and we will begin the process of inviting people from our waitlist over the coming weeks. We plan to expand access and support to additional countries and regions soon.

ChatGPT Pro

OpenAI

As AI becomes more advanced, it will solve increasingly complex and critical problems. It also takes significantly more compute to power these capabilities. ChatGPT Pro is a $200 monthly plan that enables scaled access to the best of OpenAI’s models and tools. This plan includes unlimited access to our smartest model, OpenAI o1, as well as to o1-mini, GPT-4o, and Advanced Voice. It also includes o1 pro mode, a version of o1 that uses more compute to think harder and provide even better answers to the hardest problems. In the future, we expect to add more powerful, compute-intensive productivity features to this plan. ChatGPT Pro provides access to a version of our most intelligent model that thinks longer for the most reliable responses. In evaluations from external expert testers, o1 pro mode produces more reliably accurate and comprehensive responses, especially in areas like data science, programming, and case law analysis.

Repo Prompt

Repo Prompt

Repo Prompt is a macOS-native AI coding assistant and context engineering tool that helps developers interact with, refine, and modify codebases using large language models by letting users select specific files or folders, build structured prompts with exactly the relevant context, and review and apply AI-generated code changes as diffs rather than rewriting entire files, ensuring precise, auditable modifications. It provides a visual file explorer for project navigation, an intelligent context builder, and CodeMaps that reduce token usage and help models understand project structure, and multi-model support so users can bring their own API keys for providers like OpenAI, Anthropic, Gemini, Azure, or others, keeping all processing local and private unless the user explicitly sends code to an LLM. Repo Prompt works as both a standalone chat/workflow interface and an MCP (Model Context Protocol) server for integration with AI editors.

Supermodel

Supermodel

Supermodel is a developer-focused platform that provides graph-powered tools and APIs to help AI agents and engineers better understand complex codebases, improving the quality and accuracy of AI-generated outputs. At its core is the CodeGraph API, which builds structured representations of software systems, such as dependency graphs, call graphs, and architectural maps, allowing both humans and AI models to navigate and reason about large codebases more effectively. It enables deep codebase analysis by extracting relationships between files, functions, and modules, giving instant visibility into how systems are structured and how components interact. It supports use cases like generating architecture documentation, browsing repository structure, and visualizing dependencies, helping developers quickly understand unfamiliar projects or large-scale systems.
