Otio
Otio ingests PDFs, web pages, videos, audio, and spreadsheets into a persistent research workspace, lets you run multi-step queries, and returns answers with page- or timestamp-level citations. You upload libraries, query across sources and models, and get cited answers and searchable project archives that accumulate over time.
Otio lists four public tiers (Free, Lite, Go, Pro) with monthly and annual billing columns; the pricing page shows per-plan capacity limits and explicit annual billed amounts for paid tiers.Is Otio right for you?
Good for
- Founders building a persistent, searchable research archive that needs cited answers across documents, videos, and spreadsheets.
- Answers trace back to exact pages or timestamps so you can verify claims against original sources.
- All listed AI models are available on every plan, letting you compare or retry across models without unlocking tiers.
Keep in mind
- The Free tier has strict upload and storage limits compared with paid plans, which may be restrictive for larger research libraries.
- Buyers who require documented enterprise security certifications, compliance controls, or data residency guarantees on public pages should confirm those certifications and SLAs before procurement.
Pricing and plan limits
The pricing page lists Free, Lite ($7 /mo; $84/yr billed annually), Go ($18 /mo; $216/yr billed annually), and Pro ($45 /mo; $540/yr billed annually) and documents uploads/day, storage and max-PDF-length per plan. The linked official pages do not include enterprise contract pricing or SLAs in the available information.
