Otio

Otio is an AI research workspace that helps students, academics, consultants, lawyers, analysts, and journalists work through large source libraries without losing context between sessions. Users upload PDFs, articles, videos, podcasts, and spreadsheets, then query multiple large language models against those materials with verified citations back to exact pages and passages. Built by Frontdoor Labs Ltd., Otio targets knowledge-intensive work where accuracy and source traceability matter more than generic chatbot answers.

How Otio Works

Research in Otio starts by adding sources to a permanent workspace. You can drag and drop files, capture webpages with a Chrome extension, or connect cloud and reference tools such as Google Drive, Zotero, Mendeley, Dropbox, OneDrive, and Box. Sources remain indexed in project-specific Spaces rather than disappearing when a chat session ends.

Once materials are loaded, you chat across one or many documents at once. Otio can summarize a two-hour YouTube video, pull key findings across 60 research papers, group arguments by theme, or surface contradictions between sources. Answers include clickable citations so you can verify claims before using them in a thesis, client memo, legal brief, or published article. Parallel chat lets you run two AI models on the same prompt and sources side by side for comparison.

Key Capabilities

• Multi-model access: Claude, GPT, Gemini, DeepSeek, Grok, Kimi, and Llama are available on every paid tier without model gating.
• Verified citations: Responses are grounded in uploaded sources with links to the exact page and passage cited.
• Cross-source synthesis: Query dozens or hundreds of files simultaneously to extract themes, quotes, methodologies, and gaps.
• Deep research workflows: Agentic features support multi-step research, file analysis, chart generation, and deliverables.
• Multimedia summarization: Built-in tools for PDFs, books, textbooks, podcasts, YouTube videos, and webpages.
• Spreadsheet and data tools: Upload CSV files, extract figures, and create visualizations from research data.
• Permanent research archive: Unlike session-based chat tools, Otio keeps your library searchable across weeks and months.
• Project organization: Separate Spaces keep thesis work, client projects, and personal research isolated from each other.

Integrations and Capture

Otio offers a Chrome extension for saving articles and pages directly into your library. Cloud integrations let teams sync documents from Dropbox, OneDrive, Box, and Zotero without manual re-uploads. Capture-to-chat and highlight-to-ask features reduce the friction of moving between reading and questioning. The platform reports more than 200,000 professionals using it across 74 languages.

Use Cases

• Academic researchers: Accelerate literature reviews by synthesizing large paper collections before writing.
• Consultants: Extract themes from client transcripts, reports, and briefs to build deliverables faster.
• Legal teams: Analyze discovery documents and identify facts, contradictions, and supporting passages with traceable citations.
• Financial and ESG analysts: Pull specific metrics from lengthy reports and market research without reading every page manually.
• Journalists and writers: Organize dozens of interviews, articles, and media sources into thematic outlines for drafting.

Plans and Pricing

Otio offers a free plan with limited monthly AI usage, up to 20 uploaded files totaling 100MB, one Space, and two parallel chats. Paid personal plans include Lite at $7 per month with agentic AI research, 25 uploads per day, 250MB storage, PDFs up to 500 pages, two Spaces, and five parallel chats. Go at $18 per month triples usage limits with 50 uploads per day, 500MB storage, five Spaces, and ten parallel chats, aimed at PhD students and consulting workflows.

Pro at $45 per month provides ten times the free-tier usage with 100 uploads per day, 1GB storage, PDFs up to 1,000 pages, and support for parallel research across multiple projects. Annual billing saves 50% compared with monthly pricing. A seven-day free trial is advertised on the pricing page. Business plans are listed separately for team use cases.

Positioning and Limitations

Otio emphasizes source-grounded answers over open-ended generation. When information is missing from uploaded materials, the system is designed to say so rather than invent citations. This makes it better suited to evidence-heavy workflows than quick creative brainstorming. Heavy users on the free tier will hit upload and usage caps quickly, so sustained professional research generally requires a paid plan.
