7 AI models. One workspace.
Claude, GPT, Gemini, DeepSeek, Grok, Kimi, Llama - all in one workspace, running against your uploaded research sources, with every answer cited back to the exact page.

Real research isn't one question at a time. Every tab switch starts you over.
6 Hours Per Week Lost to Tab Switching
Copy-pasting source text into ChatGPT that forgets it an hour later. Opening Claude, re-uploading the same PDF, typing the same question, switching back to compare, and losing your train of thought somewhere in the middle.
Every time you switch tools, you're starting over.
$60 to $80 Per Month on Stacked Subscriptions
ChatGPT Plus, Claude Pro, Gemini Advanced, Perplexity Pro. Four $20/month subscriptions because no single tool gives you all the models, and you need to compare outputs to trust the answer.
The cost isn't just financial. It's the context loss and the cognitive load of four workflows.
Hallucinated References You Can't Verify
ChatGPT invents authors, fake journals, and page numbers that don't match. Claude summarizes without citing. Gemini gives you an answer but no trail back to the source.
When your work depends on accuracy, you need every claim traced to the exact passage.
The 4-Tool Workaround People Are Actually Using
One popular LinkedIn post suggested running every research question through ChatGPT, then Claude, then Gemini, then Perplexity, and manually comparing the outputs. That's the workflow people have settled for.
Otio replaces all four with one workspace. Same sources, every model, cited answers.
Parallel AI Threads lets you run two models at the same time, against the same sources, with both answers side by side. No other research workspace does this.
Claude and GPT, same prompt, same sources
Both answers visible at once. No re-uploading, no re-prompting, no switching tabs. Ask one question, see two interpretations.
Compare how models read your research
Claude might catch a nuance GPT missed. GPT might structure it more clearly. Evaluate both without losing your place.
Real research holds multiple threads at once
Every other AI tool makes you wait your turn. Otio runs parallel lines of thinking so your momentum and context stay intact.
No other tool does this
Poe gives you models in a chat. NotebookLM locks you to Gemini. ChatGPT, Claude, Perplexity each lock you to one. Otio runs two at once on your sources.

Same source. Two minds. One workspace.
Every AI Model. On Every Tier. No Gating.
Claude, GPT, Gemini, DeepSeek, Grok, Kimi, Llama. Switch between models mid-session without losing your sources or your conversation. Every model. Every plan. No upsell walls.
