Compare AI models, explore different perspectives, and evaluate answers from one powerful workspace. Stop switching tabs. Start seeing the bigger picture.
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.
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.
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.
Real workflows from the app: compare, evaluate, and create.
One workspace, six workflows. Pick the right one for every question.
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.

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.

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.

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

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.

Pick one model and tune it like a lab instrument. Adjust temperature, tokens, penalties, and reasoning effort. Set a system prompt, control context depth, and save your best setups as reusable profiles.
Small touches that make a big difference when you use AI every day.
Staring at a blank prompt box? Hit the magic wand and Prism rewrites your prompt to be clearer, more specific, and more likely to get a great answer.
Organize your conversations into color-coded folders. Collapse what you are not using, find what you need instantly. Your sidebar stays clean no matter how much you chat.
Save your best prompts and reuse them anytime. Use {{variables}} as placeholders, and Prism will ask you to fill them in each time you insert the prompt.
In Compare mode, one click analyzes all model responses and highlights exactly where they contradict each other. Stop guessing, start knowing.
