Best Tools

This Tier C Starter Guide, built from the providers’ public pages, helps you match one first job to one of eight AI tools: ChatGPT, Claude, Gemini, Grok, Perplexity, Runable, Kimi or Mistral Vibe. FSR tested none of them. It names no default tool, because free use comes with conditions: several tools use chats for training unless you opt out, share links can be public and credits run out. It shows what to check before you type, how to test once with invented material and when to stop.

An AI coding assistant reads your repository and writes or reviews code on your behalf. Future Stack Reviews put six buyer questions to ten of them on 21 August 2026: training terms, IP indemnity, how much of the allowance reaches the model, which portion is variable, concurrency, and which client may spend it. The published pages answered fifteen of the sixty. Document-first, no hands-on testing, no ranking.

A shared model name does not identify the same service. This document-first briefing compares five AI image buying routes on the parts a buyer can verify before paying: the meter, the contract, the exposed controls, the data path, and the retirement date.
