Freefree-tierAnthropic
Claude, built by Anthropic, is the tool we reach for when the task is a 100-page report, a contract redline, or writing that needs to stay on voice. Its free tier in 2026 gives you Claude Sonnet 4 for everyday work and a rotating allowance of the flagship model.
What stands out
- Very large context window — paste entire documents and ask specific questions without losing the thread.
- Calm, precise prose — strong for editing, summarization, and nuanced instructions.
- Free tier covers chat, document analysis, and coding help.
How we tested it
We fed Claude a 90-page PDF and asked for a one-page executive summary plus a risk list. Output was accurate and well-structured. We also used it to tighten marketing copy; it preserved tone better than rivals we tried.
