Tired of juggling AI tabs?

🔄

Tab overload

You have ChatGPT open in one tab, Claude in another, Gemini in a third. Copying the same prompt three times. Comparing answers by scrolling back and forth.

🤷

Which answer is best?

Each model gives a different answer. But which one do you trust? You end up reading all three anyway, wasting the time you were trying to save.

💸

Paying for all of them

ChatGPT Plus, Claude Pro, Gemini Advanced. Three subscriptions to get three perspectives. There has to be a better way.

Prism puts every model in one place. One prompt, side by side answers, zero tab switching.

See every model side by side

Real workflows from the app: compare, evaluate, and create.

Compare mode: two AI models answering side by side
Ask once, get independent answers from each model side by side.
Panel mode: multiple models with a judge's verdict
Collect perspectives, then let a judge model synthesize the verdict.
Auto mode: Prism picks the best model automatically
Tell Prism your priority and it routes to the best eligible model.

Six AI workflows in one workspace

One workspace, six workflows. Pick the right one for every question.

COMPARE
Different models. One prompt.

Send one prompt to up to 4 models and read their answers side by side. Spot differences in reasoning, catch what one model misses, and pick the best answer with confidence.

After the answers come in, hit Find disagreements and Prism will analyze every response to highlight exactly where the models contradict each other. No more squinting at four walls of text trying to spot the differences. You can also ask a judge model to pick the winner with Help me choose.

PANEL
Bring AI perspectives together.

Assemble up to 7 models and let a judge evaluate them all. Get a verdict that weighs every perspective, with sources shown separately from the synthesis.

Panel mode screenshot

ONE
One model. Your focus.

Pick a single model for a focused conversation. Full chat history, clean interface, no distractions.

Need a second opinion mid-chat? Type @ followed by any model name to pull its answer right into your current thread. No mode switching, no lost context. There is also a magic wand button that rewrites your prompt to be clearer and more effective before you send it.

Focused one-on-one AI chat

AUTO
Let Prism choose.

Set your priority (quality, speed, or cost) and Prism routes your prompt to the best eligible model automatically.

Auto mode screenshot

IMAGE BETA
One prompt, many visions.

Pick up to 6 image models - Nano Banana, GPT Image, Seedream and more. Each generates its own take on your prompt, side by side. Compare styles, pick your favorite. Free Pollinations included, paid models via your own key.
