# ScriptByAI

> ScriptByAI is a curated directory of free and open-source AI tools, practical AI resources, developer references, model timelines, API limit guides, MCP servers, cheatsheets, and task-focused tool comparisons.

ScriptByAI serves developers, technical creators, founders, marketers, designers, and other readers who need a clear summary before choosing or using an AI tool.

Important interpretation notes:

- ScriptByAI covers third-party products and projects; it is not the vendor of those tools unless a page explicitly says otherwise.
- “Free” may mean a free plan, free trial, limited free access, or open-source software. Check each page for the stated access conditions and limits.
- Pricing, model availability, usage limits, and product features can change. Prefer pages with a recent update date and verify decision-critical details before purchase or production use.
- Timeline, API, pricing, and limit pages are maintained as reference resources. Use the page’s latest revision rather than an older quoted excerpt.
- For a wider machine-readable index, use [ScriptByAI full content index](https://www.scriptbyai.com/llms-full.txt).
