7 Best Free AI Tools for 2026
An overview of AI tools that are genuinely free and useful in practice, not just a limited free tier.

1. Claude.ai (free tier)
What it does: Writing, text analysis, document summarisation, coding
Anthropic offers a free tier that in 2026 still includes access to the Claude 3.5 Sonnet model. The limit is on the number of messages per day (roughly 15-20 longer conversations), but with no other restrictions.
