One Prompt.
Every AI.
Assign different tasks to different models in one prompt.
Sound Familiar?
Every AI user hits these walls. We built AskOnce to tear them down.
Tab Overload
You're copying the same prompt into ChatGPT, Claude, and Gemini in separate tabs. Every. Single. Time.
Solved by Parallel PromptingWhich AI Is Right?
Every model gives a different answer. Without seeing them together, you're just guessing which one to trust.
Solved by Side-by-Side ComparisonLinear Chat Limits You
Chat interfaces force you into a single thread. Complex thinking needs space to branch, connect, and rearrange.

Parallel Mode
Chain AI models sequentially — each one builds on the last.
"@gpt outline, @claude write, @gemini fact-check"
GPT-4
Writes the outline
Claude
Writes the body
Gemini
Fact-checks & cites
AskOnce can chain multiple AI models together. Each model builds on the previous output, creating a smarter final response.
Canvas Mode
BetaA spatial canvas where you place model responses, rearrange ideas, draw connections, and prompt freely.

One Collaborated Response
AskOnce combines every model's output into one final answer — each model did its specific job, delivered as a single complete result.

Get The Response You Wanted
When models work sequentially, one hallucination poisons every step after it. Parallel mode keeps each model independent — so a wrong answer from one never infects the others.
Researches topic — gives accurate context
Reads Model A's output — adds a made-up stat
Reads Model B's output — builds on the false stat

Frequently Asked Questions
What exactly does AskOnce do?+
AskOnce lets you send a single prompt to multiple AI models simultaneously. You see all responses side-by-side, can assign different tasks to different models, or use our spatial canvas.
Which AI models do you support?+
We support GPT-4, Claude, Google Gemini, Meta Llama, Mistral, and more. We're adding new models regularly.
What is Canvas Mode?+
Canvas Mode is a spatial workspace where you can place AI responses anywhere, draw connections between ideas, rearrange freely, and prompt from any point.
Do I need API keys?+
No! We handle all API integrations. Just sign up and start prompting.
How does Parallel Mode work?+
In Parallel Mode, you assign different tasks to different AI models in a single session. GPT writes an outline while Claude drafts the body and Gemini fact-checks.
Can I use this for my team?+
Absolutely. Our Team plan includes shared canvases, collaboration features, and team management.
