Discover and compare tools by price, features and use case, or ask Lumi to narrow the options for your work and budget.
An AI tool wraps one or more models in features for a specific job. Start with the outcome you need, then compare evidence instead of choosing the loudest brand.
One AI Guide is an independent directory and decision guide for AI tools. Our curated catalog covers 500+ AI tools across writing, image, video, audio, coding, research and hardware, and helps you pick the right one for what you are actually building.
Yes. Browsing tools, comparing them, reading guides, asking Lumi for recommendations and building personal stacks is completely free, no sign-up required. We earn through affiliate links on some outbound buttons, which never changes the price you pay.
Our catalog is curated. We only label a tool editorially tested when its complete hands-on test record is published; other listings are not presented as tested. Listings show available pricing, strengths, weaknesses and best-for scenarios where evidence is available. Smart Compare labels comparison evidence as verified, partial or unknown. Brands cannot pay for a better rating, and sponsored placements are clearly labelled.
An AI stack is a chain of two or more AI tools combined into a repeatable workflow, for example a writer plus an image generator plus a video tool to produce a short. On One AI Guide you can browse community stacks, fork them, and build your own.
Yes. Every tool detail page lists vetted alternatives, and we publish dedicated pages at /alternatives/<tool> that compare each tool to similar options in the catalog. The recommendations come from real overlap, not keyword matching.
Yes. The /gear page covers AI hardware including smart glasses, AI recorders, translators, wearables, drones and smart-home devices, with selected editor-tested picks and category notes.
Many tools offer a limited free plan; paid plans commonly add higher usage, better models, team controls or commercial rights. Start with a free plan or short pilot when it covers your real task, then compare seat fees, usage credits, add-ons and review time before upgrading.
Check what data the provider stores, whether prompts may train models, retention and deletion controls, access permissions, regional or industry requirements, and how outputs can be verified. Test with non-sensitive data first and keep a person responsible for important decisions.
Usually not. Many writing, research, image and productivity tools work in a browser with plain-language instructions. Start with one narrow task and a beginner-friendly interface; technical setup matters more when connecting APIs, automations or company data.
