Short answers to the questions people ask about choosing an AI, writing a prompt, and keeping chats private. Model names, prices, and privacy lines come from the stored rankings, so they move when those records move.

Gemini's maker, Google, leads Writing & Marketing, Speed & High Volume, General & Everyday, and Video. Alibaba leads Research & Web Search. WhichAI.today picks by the job instead of crowning one brand.
The stored free pick for everyday questions is MiMo-V2.6-Pro. Access to public model and dataset repositories, community Spaces with CPU Basic and ZeroGPU hardware, and monthly free inference credits; limits include lower compute queue priorities and rate limits Each job page lists its own free pick.
You can start without paying. Free plans are stored for several apps. The lowest stored paid plan is Google AI Plus on Gemini at $4.99/month.
A scheduled job checks the public boards every day. A new number one has to come up on two checks in a row before it replaces the current leader, so a one-day blip does not flip the pick. The latest recorded update is Nov 12, 2026.
An AI model is the system that writes the answer, such as Gemini 4 Carbon. An AI app is the product you open to use a model, such as ChatGPT, Claude, or Gemini. One app can offer several models.
A prompt is the instruction you type into an AI. A useful prompt says what you want done, who it is for, and what the answer should look like.
Name the goal, context, format, tone, and constraints. Say what you want done. Name the audience, or paste the material inside the brackets. Say what the finished answer should look like. Say how the answer should sound. Add a limit, such as length or what to leave out. Leave anything you do not know yet in [brackets], and fill those in before you send the prompt.
Long enough to name the goal, the audience, and the format. A short task can be a few sentences. Put a long document in the context, separate from the instruction, instead of mixing the source into the request.
The same five parts work for ChatGPT, Claude, and Gemini: goal, context, format, tone, and constraints. Each maker also publishes extra habits, and WhichAI.today stores a sourced guide for each of those three.
An AI can state a false name, number, or date as if it were known. Ask it to use only the facts you gave, and check names, numbers, and dates yourself before you rely on the result.
Yes. The prompt builder writes a prompt for today's leader for the job you describe. It fills the goal, context, format, tone, and constraints, and leaves unknown details in brackets.
It depends on the app and the setting. ChatGPT: Yes on personal Free, Plus, and Pro. Improve the model for everyone is on by default. Opt out: Settings, Data controls, turn off Improve the model for everyone. Claude: Anthropic says Free, Pro, and Max chats are used for training only if you allow it, and you choose at signup. The toggle has been reported as on by default, so check it. Opt out: Settings, then Privacy. Turn off Help improve Claude. Gemini: Yes for adults. Gemini Apps Activity is on by default, and those chats can be used to improve Google AI. Opt out: Gemini Apps Activity, turn off Keep Activity. Safety review can still apply.
Use an open-weights model you can run yourself when files cannot leave your network. The open-weights pick for everyday questions is MiMo-V2.6-Pro. Ollama is stored as a local app.
An open-weights model publishes its weights so you can download and run it yourself, often on your own hardware. Every ranked job on WhichAI.today includes one.
Public evaluations: LMArena, Artificial Analysis, Vals AI, SWE-bench, GPQA, and Humanity's Last Exam. A daily job rechecks those sources. A new number one has to appear on two checks in a row before it replaces the current leader. The planner does not invent model names.
Yes, WhichAI.today is free. There is no account and no paywall. No paid placement, and no affiliate links in the picks. A model is listed because of the public board for that job.
