Pricing
Last Updated July 7, 2026
Simple pricing. Every model, no limits, on every plan.
Every AI model - ChatGPT, Claude, Gemini, Grok and more - on every plan, including Free. No file upload limits, no source caps. Deep Research and page-level citations included. You only ever pay for volume, never for features.
What you never pay extra for
Every model, every plan
ChatGPT, Claude, Gemini, Grok, Llama, DeepSeek and Moonshot, plus Otio Auto which picks the right model for you. Compare two side by side on the same sources. Most tools lock the best models behind their top tier. Otio gates none of them, even on Free.
No upload limits, no source caps
ChatGPT caps files per day and NotebookLM caps sources per notebook. Otio doesn't cap your library, upload as many PDFs, papers, web pages, YouTube videos, podcasts and spreadsheets as you need.
Deep Research on every plan
Multi-step research across your own sources and the open web, with every answer cited to the exact page or timestamp, included on Free, not reserved for a premium tier.

Every plan includes all AI models, Deep Research, and page-level citations. Paid plans differ only by volume and a few workflow conveniences, never by which core features you can use.
One subscription. Every model.

Otio Auto
Switch model mid-chat, or let Otio Auto choose. Quick-picks - Auto, Fast, Expert - match the model to the job. Compare two models on the same question, side by side. No plan hides a model from you, and there is no per-model paywall.
From a pile of sources to something you can use
Chat with your PDFs and videos
Ask questions across everything in your library at once and get one answer, cited to the exact page or timestamp.
Deep Research, grounded
Run multi-step research across your sources and the live web — every claim traceable, no black box.
Make notes from any PDF or video
Turn a source into editable, structured notes you can refine inline and export as markdown.
Charts and analysis from spreadsheets
Upload a CSV and get data analysis and visualisation without leaving the app.
Then deliver it where you work - email it to yourself, drop it in Google Drive, send it to Telegram, and more. Otio gets you through the reading and organising faster; the final thinking and writing stay yours.

"I tend to use several AI tools simultaneously. That's precisely what attracted me to Otio - the possibility of having all of them in one place."
Otio user
"I needed something that allowed me limitless tries of GPT-4, Claude, Llama3, Mistral & Perplexity AI Web Search all at one place. And this is actually cheaper than ChatGPT. Otio has increased my productivity to 5x better than before, saves hours."
Otio user
"I tried ChatGPT Projects for a deeper academic task and realised they cap it at 25 files per project. That limitation really affects the way I do my work."
