- Leonardo.Ai: A daily allotment of free credits with strong control over style and composition.

Always check each tool’s licensing terms before using generated images commercially.
AI Writing and Productivity
Beyond chatbots, specialized tools speed up everyday work:
- Grammarly: Free grammar, spelling, and clarity suggestions as you type across the web.

- Otter.ai: Transcribes meetings and generates summaries, with a useful free tier.

AI for Coding
Developers benefit hugely from AI assistance:
- GitHub Copilot: Free for students, teachers, and maintainers of popular open-source projects, with a limited free tier for everyone else.
- Codeium: A genuinely free AI coding autocomplete that works across many editors.
- ChatGPT and Claude: Both excellent for explaining code, debugging, and generating snippets in their free tiers.
How to Choose and Use Free AI Tools Wisely
With so many options, focus on a few that fit your workflow rather than collecting them all. A practical starter set is one chatbot (ChatGPT or Claude), one image generator (Copilot or Leonardo), and Grammarly for writing. Keep two cautions in mind: free tiers have usage limits that can change, and you should avoid pasting sensitive personal or company data into any AI tool unless its privacy terms clearly allow it.
