Official FAQ

Can I trust Otio to give me accurate information?

Otio is designed to work with your sources, not around them. It generates answers only from the material you've uploaded, cites every claim back to the exact source, and tells you when something isn't there, rather than inventing an answer to fill the gap.

How does Otio cite its answers?

Every answer Otio generates includes a citation to the exact page and passage in your uploaded source. Click the citation, and Otio jumps you straight to the source text so you can verify before you use it. Unlike tools that generate plausible but unverifiable summaries, Otio only answers from the material you've uploaded. If the answer isn't in your sources, Otio tells you instead of inventing on

Why wouldn't I just use ChatGPT for research?

ChatGPT is built for general conversation. Otio is built for research. ChatGPT doesn't remember your sources between sessions, has a 10-file upload cap per message, and can hallucinate citations with invented authors, fake journals, or page numbers that don't exist. For a one-off question, ChatGPT works fine. For a research project spanning weeks and dozens of sources, Otio is built for what ChatG

Is Otio only for academic research?

No. Otio is built for any professional who works with large volumes of sources, whether you're a researcher managing 60 papers, a consultant synthesizing 30 client documents, a lawyer working through discovery files, an analyst processing earnings transcripts, a journalist tracking a 40-source story, or a student building a thesis from mixed-format materials. If your research involves reading, syn

Can I use multiple AI models in Otio?

Yes. Otio supports Claude, GPT, Gemini, DeepSeek, Grok, Kimi, and Llama. Every model is available on every plan, including the free tier, with no gating or paywalls. You can switch models mid-session or run the same question through different models to compare answers. Your sources and conversation history stay intact, so you can choose the right model for the task without losing context.

How many sources can I upload to Otio?

Otio has no source caps. You can upload 60 papers, 30 client documents, 50 web articles, and 20 videos into the same workspace, then chat across all of them without hitting file limits or session resets. Otio is built for research projects that accumulate sources over weeks and months, not just one-off questions.
