OASIS review
Open-source voice and text interview tooling for teams that want deployment and model control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OASIS is an open-source system for running AI-powered conversational interviews and survey protocols. It is aimed at academic and research teams that want methodological control, model flexibility and data sovereignty, especially technical teams able to run their own infrastructure. Interviewers can configure voice or text agents, preset questions, probes and transitions, with rule-based adaptive behavior and engagement metrics. Participant identifier modes support different tracking approaches, while transcripts, analytics and exports help teams review sessions. The project launched publicly in March 2026, so it is a young option in this category.
Deployment and operating costs are central to the choice. OASIS runs in Docker on local or cloud infrastructure and stores data in the operator’s PostgreSQL database. It has no vendor-hosted pricing; the software is open source, while external model, speech or telephony providers configured by the operator may charge separately. Supported options include OpenAI, Google Gemini, Anthropic, Mistral, Azure OpenAI, Deepgram, ElevenLabs and Twilio. Twilio telephone interviews support incoming calls and are in beta. Teams should account for setup and ongoing provider management rather than expecting a hosted service with one bundled price.
The feature set is oriented toward controlled interview workflows: voice-to-voice sessions can use OpenAI Realtime or Gemini Live, and knowledge-base retrieval is supported with pgvector. Diarized transcripts and CSV or JSON exports provide paths for analysis and downstream workflows, with Qualtrics, LimeSurvey and REDCap among the listed integrations. Email and documentation are the stated support channels. Choose OASIS if self-hosting, provider choice and interview protocol control matter more than a broad survey suite. Teams seeking a turnkey hosted platform or a wider set of survey capabilities should consider alternatives.
OASIS pros and cons
- Where it wins
- Runs voice and text interviews with adaptive rules and semi-structured protocols
- Offers diarized transcripts, session analytics and CSV/JSON exports
- Supports multiple model, speech and telephony providers
- Where it doesn't
- Requires Docker-based deployment and operator-managed infrastructure
- External model, speech and telephony providers may add operating costs
- Its focus is interview tooling, not a broad survey platform
