List of Free LLM AIs for Coding (June 2026)

Large language models (LLMs), the generative AIs that respond to text-based questions, can be a useful resource for learning to program. This blog post is a simple list of LLM services that are free, do not require a credit card to use, and have a web interface. I'll update this blog post from time to time. Assume that free services may have daily usage limits, and that sites that don't require registration may limit how much you can use them before signing up for a free account.

You should absolutely assume that all content you submit as well as your browser settings and IP address are recorded, sold, and matched to your personal identity otherwise by the AI company.

My rough top recommendations for coding tutors are ChatGPT, Claude, and DeepSeek, but here are the acceptable free AI services I've found:

• Duck.ai (from DuckDuckGo) - No registration required. Uses other AI companies' models but acts as an anonymous relay. (This is not verfied.)
• ChatGPT (from OpenAI) - No registration required.
• Gemini (from Google) - No registration required.
• Claude (from Anthropic) - Free account registration required.
• DeepSeek (from DeepSeek) - Free account registration required.
• Copilot (from Microsoft) - No registration required.
• Poe (from Twitch.tv) - Free account registration required.

I don't recommend the following for their deceptive UI practices (They appear free but require registration after you've submitted a prompt):

• Perplexity (from Perplexity)
• Mistral (from Mistral AI)
• Meta (from Meta / Facebook)
• Grok (from X / Twitter)

I have slight recommendations against the following:

• Shiori (from Shiori.ai) - Free account registration required. Uses other AI companies' models. I don't recommend it because this probably means their business model is personal information collection. They may be fine, but they don't have the reputation of DuckDuckGo for privacy.
