AI tools compared, indexed, and rated.
Type your monthly token volumes and cache hit rate. See real $/month across every frontier model — Opus 4.8, Sonnet 4.6, GPT-5.5, Gemini, Grok.
Open the calculator PickerFour questions, one answer. Workload shape, cache profile, cost stance, special needs — and the picker tells you the model you should default to, with why.
Open the picker DiagnosticPaste your system prompt. The diagnostic flags every pattern that silently tanks your cache — timestamps, UUIDs, per-user template vars — and gives you the exact fix. Runs entirely in your browser.
Open the diagnostic LibrarySix vetted, cache-friendly system prompts you can copy and ship — coding agent, customer support, RAG, classifier, content drafter, research analyst. Each one scores 95+ on the diagnostic.
Browse the librarySeven AI agents tested on the same task suite — Manus, Devin, Operator, GPT Agent Mode, Gemini Workspace, Replit, Claude Computer Use. Two are genuinely useful today; the rest need a specific use case.
Six AI coding tools, one honest conclusion: there's no single winner, and the best developers pair two. Here's what each is actually for, what it costs, and which combination fits your workflow.
We tested seven AI writing tools on the same set of tasks. Three are great, three are fine, and one is genuinely worse than nothing. Here's how they stack up.
The five vector stores worth considering in 2026 — what each costs, how fast it is, and the one question that decides most of them: do you even need a dedicated database, or is Postgres enough?
A weekly read on what changed in AI — written by humans, fact-checked twice. No hype, no filler.
