Why OASIS Exists

There's no shortage of conversational AI platforms. What's missing is one that puts survey methodology first.

The Short Version

In several research projects, colleagues and I have relied on commercial tools for conversational AI agents. They're good, and in many ways impressive. But they don't really cater to research designs: probing logic, follow-up strategies, semi-structured and unstructured interview protocols, participant identifiers, or the kind of pricing model that works for an unfunded PhD project.

That's why I started OASIS. It's not trying to compete with commercial platforms. It's trying to be an open-source alternative for transparent research, a survey interview platform that runs entirely inside your Docker environment, talks to whichever AI providers you choose, and treats research methodology as a first-class concern rather than an afterthought.

To be clear: the ambition here is not to match enterprise platforms with dedicated engineering teams and substantial funding behind them. They will always move faster and offer more polish. But it is important that open, transparent alternatives exist for research. Tools you can self-host, inspect, and adapt to your study design without a procurement process. That is what OASIS is for.

Read the longer version

The gap isn't about capability. LLMs can already conduct nuanced, adaptive dialogues. It's about tooling. You can subscribe to an enterprise platform that handles everything, but then your data lives on someone else's servers, your prompts are proprietary, and switching providers means starting from scratch.

Alternatively, you can stitch together WebSockets, STT engines, LLM APIs, and TTS services yourself, which is fine if you have a software engineering team, but most research groups don't.

OASIS sits in between. It handles the engineering (audio pipelines, real-time transcription, session management, model routing) so researchers can focus on what they're actually good at: designing interview protocols, crafting questions, and interpreting data.

Importantly, OASIS can run in your own Docker environment. If your deployment calls external AI APIs (OpenAI, Google, etc.), that's your choice of provider. OASIS itself never phones home and never sees your data. For full isolation, you can point it at self-hosted models on GCP, Azure, or Scaleway.

Design Principles

Full sovereignty over data

Your transcripts, your database, your servers. Everything runs inside your Docker deployment. External API calls to AI providers are your explicit configuration choice. OASIS itself doesn't transmit data anywhere.

Provider agnosticism

OpenAI, Google, Anthropic, Mistral, Scaleway, or your own fine-tuned model on GCP Vertex AI. OASIS doesn't lock you in. Swap models with a config change.

Research-first design

Semi-structured protocols, participant tracking, diarised transcripts, session analytics. The features survey researchers actually need, not chatbot novelties.

European data residency

Deploy on Scaleway or any EU-based provider for GDPR compliance. Self-hosting means you choose the jurisdiction.

Max M. Lang

DPhil Researcher · University of Oxford

I study how we gather high-quality data and extract valuable information to answer important questions. My work spans spatial epidemiology at Oxford, survey methodology at LMU Munich, and engineering projects including automated telephone surveys with 60 Decibels (20,000+ interviews and counting) and adaptive AI interviewers.

OASIS is what I wished existed when I started this work.

Early concept that evolved into OASIS

Looking Ahead

The Bigger Picture

Right now, the focus is on the OASIS Platform: a solid, self-hosted tool for conducting AI-powered conversational interviews. But the long-term vision is bigger.

I see OASIS growing into a hub for AI-enabled survey methods that researchers can self-host. Conversational interviewing is just the first module. Future directions include:

🧪 Survey Pretesting with LLMs

Use LLMs to simulate respondent behaviour and stress-test your questionnaire before fielding it.

📊 Synthetic Data Generation

Simulate survey responses with LLMs for pilot analyses, power calculations, or methodology research.

🔍 Qualitative Coding Assistants

AI-assisted thematic analysis and coding of interview transcripts, with human oversight at every step.

🌐 More to Come

The intersection of AI and survey methodology is wide open. New use cases will emerge as the field evolves.

An honest note: Everything under the OASIS umbrella is new and still being actively researched. These are not solved problems. The methods are evolving, the best practices are still being written, and there will inevitably be obstacles along the way. That's the whole point: together, we can figure it out. But figuring it out also means running into dead ends, making mistakes, and iterating.

With great power comes great responsibility

AI-powered interviewing is a powerful tool. It must be used ethically and responsibly. OASIS is built for legitimate research purposes: advancing science, understanding communities, and improving lives. It should not be used for deception, manipulation, surveillance, or any application that harms participants or undermines informed consent. As researchers, it is our collective responsibility to set that standard.
