Best context window AI tools

Kaipsul is an innovative macOS application that leverages Apple Intelligence to pre-process large text datasets, compressing them by up to 90% while preserving semantic meaning. It enables AI models to handle more context, overcome "context window exceeded" errors, and achieve sharper reasoning, all through 100% local, on-device processing.

A free, quick-reference web tool for developers, researchers, and AI enthusiasts to check the token limits of popular AI models. It provides a centralized, up-to-date database for text, image, and embedding models, simplifying workflow and development.

A free web tool that intelligently splits long text or prompts into smaller, manageable chunks optimized for ChatGPT and other LLMs. It uses token-counting to bypass character limits, ensuring efficient and seamless interaction with AI models.

A free, privacy-focused online tool for accurately calculating text token counts for a wide range of Large Language Models (LLMs). It supports popular models from OpenAI, Anthropic, Meta, Mistral, and more. By performing all calculations directly in your browser, it ensures your prompts remain confidential. This is an essential utility for developers, writers, and researchers to manage LLM context windows, prevent errors, and optimize API usage without compromising data security.

A free web-based tool that automatically splits long text or prompts into smaller, manageable chunks to overcome the character limits of large language models like ChatGPT, ensuring complete context and better AI responses.
