Tellet
Tellet is a Dutch AI interview platform that runs and analyses qualitative consumer research at scale. Its AI moderator probes respondents in 57 languages, accepts voice, video or photo replies, then transcribes and surfaces themes in one click.
What is Tellet?
Tellet is a web platform, built by the Amsterdam company Tellet B.V., that uses AI to conduct and analyse qualitative consumer research interviews. Its pitch is to deliver the richness of qualitative work at the speed and scale of a quantitative survey.
The workflow mirrors briefing a human researcher. You give the AI interviewer an objective, a set of questions and a brief with useful context, then send the interview link to your customers, or let Tellet recruit respondents through partner panels such as Prolific, Pure Spectrum and Norstat. From there the AI runs the conversation itself, generating follow-up questions in real time from whatever the person has just said.
What makes the output unusual is how respondents answer. Rather than typing short replies, they can record voice notes, video or photographs, which Tellet argues surfaces the opinions, motivations and emotions that text boxes flatten. The platform claims 57 languages: a discussion guide written in English can be answered in whichever language the participant prefers.
Analysis is the second half of the product. Transcription is automatic, and a single click returns key themes, emerging patterns, opportunities and recommendations rather than a plain summary. An AI Search feature then lets teams question the transcript corpus months after fieldwork has closed.
A second product, Tellet Embed, is narrower: it places a conversational module inside an open-ended question of an existing survey through an iFrame, working with Qualtrics, Dimensions, Forsta or any platform that accepts iFrames. Answers come back enriched, with automated theme coding and confidence scores; sentiment analysis is announced as coming. Those pages claim 300,000+ responses delivered and 1,000+ concurrent users.
On compliance, Tellet runs on Azure OpenAI and states that no model is ever trained on customer data, that interview data sits on servers inside the EU, and that AES256 encryption is used. ISO 27001 is advertised as coming soon rather than held. Access is browser-only, with no mobile app and no public API. Named references include Vodafone Ziggo, Royal Swinkels, Humanise and Blauw research.

Pros & Cons
Pros
- Qualitative depth at quantitative scale, with findings in hours rather than weeks
- 57 languages without translation work or locally hired moderators
- Voice answers capture emotion and motivation that typed survey boxes lose
- AI Search keeps old transcripts answerable months after fieldwork ends
- No model training on customer data, and interview data hosted inside the EU
- A published unit rate of EUR 25 per interview, which is rare in this market
- Tellet can recruit the respondents, and incomplete Embed surveys are not billed
Cons
- No public API and no developer documentation
- No free plan and no free trial; every purchase goes through a quote
- The real entry cost is high: a EUR 750 platform fee on top of EUR 25 per interview, and a EUR 3,000 minimum bundle for Embed
- ISO 27001 is advertised as coming soon rather than actually held
- No DPA and no subprocessor list are published, and retention is never given as a figure
- User documentation is unreachable: the guide pages listed in the sitemap render nothing
- Site upkeep is patchy, with a dead cookie policy page, a terms link that returns 404, and a contact block showing one email address while linking another
Pricing & Plans
No free plan and no free trial are advertised. Tellet's own cost calculator prices the interview platform at EUR 25.00 per interview, to which a EUR 750 platform fee, also labelled project management fee, is added; the worked example published on the site totals EUR 3,250 for 100 interviews, and projects are capped at 1,000 interviews. The Tellet Embed product is priced at EUR 1.00 per module, a module being one scripted open-ended question plus two AI follow-up probes, with a minimum bundle of EUR 3,000; incomplete surveys are not charged. Respondent recruitment is an optional extra priced per market, and some markets require a custom quote. All amounts are displayed in euros, and purchase proceeds through the quote form rather than a self-service checkout.

Data, GDPR & hosting
A consolidated view of how Tellet handles your data.
GDPR overview
Tellet claims GDPR compliance explicitly. Tellet B.V. says it collects and processes personal data under the EU GDPR, the Data Protection Act 2018 and other relevant Dutch, UK and EU legislation, and names a Data Protection Officer reachable at dpo@tellet.ai. The privacy policy lists the full set of rights: withdrawing consent, access, rectification, erasure, portability, restriction, objection, and freedom from discrimination for exercising them. Two supervisory authorities are named for complaints, the Dutch Autoriteit Persoonsgegevens and the UK Information Commissioner's Office. Respondents give explicit consent through an 'I Agree' statement before an interview starts. AES256 encryption is claimed; ISO 27001 is advertised as coming soon and is not yet held. As a Dutch-established company Tellet needs no Article 27 representative, and none is named. The policy is version 1.0, created on 18/10/2023 and last revised on 08/02/2024.
Who owns the data?
Tellet B.V. splits its role in two. When it provides the platform for clients to run interviews and analysis it acts only as a data processor, and the client commissioning the study is the controller who sets the purposes and conditions of processing. When Tellet handles account management or its own marketing, it becomes the controller of that data. Towards respondents, Tellet states it acts solely as a processor on behalf of the organisation running the research. Interview content therefore belongs to the client rather than to Tellet: individual and collective responses are reported back to the commissioning client, and any sharing with a third party requires either the respondent's permission or a processor contractually bound to confidentiality.
Reuse rights
Tellet states it does not reuse interview data for its own purposes, including product development or analytics unrelated to the study. The platform is built on Azure OpenAI and Tellet says no models are ever trained on customer data, with processing carried out only on the controller's instructions. The client that commissioned the study receives both individual and collective responses and uses them for the research project it defined. Third-party sharing is limited to two cases: the respondent asks for or permits it, or the recipient is a processor contractually bound to confidentiality and to research or statistical use only. Tellet also states that it makes no automated decisions carrying significant or legal consequences for respondents, and that Google Analytics cookies are set only with consent, under a signed agreement with Google.
Data retention & training
Hosting summary
Tellet states that all personal data collected in interviews is stored securely on servers located within the European Union, and retained only as long as necessary. No individual hosting country is named, and no cloud provider is identified for that storage; the AI layer is Azure OpenAI, with no region specified. Tellet claims AES256 encryption and says all information is held on secure servers, while warning in its privacy policy that no internet transmission is completely secure and that absolute security cannot be guaranteed. One distinction is worth keeping straight: the tellet.ai domain resolves to a United States IP address on Amazon infrastructure, but that is the marketing site, not the interview data, which Tellet places in the EU. Backups and archives are described as kept in a secure environment for a set period before being permanently deleted.
Things to keep in mind
Risks and trade-offs to weigh before adopting Tellet.
- Respondents' voice, video and photo answers are third-party personal data: the client is the controller and needs its own legal basis, not merely Tellet's compliance claims
- Voice and video can reveal identifiers even though Tellet says it never asks for identifying details, so participants may believe they are more anonymous than they are
- Interviews may touch special category data such as health, beliefs or ethnicity; respondents can decline, but the prompt comes from a machine that cannot read hesitation
- The headline EUR 25 per interview understates the real cost once the EUR 750 platform fee, or the EUR 3,000 Embed minimum, is counted
- Retention has no published duration, and no DPA or subprocessor list exists to bound what happens to the recordings
- Replacing human moderators wholesale risks losing the researcher's judgement about when a line of questioning should stop or soften
- The terms disclaim any obligation of result and refuse refunds for disappointing quality, so background noise, poor microphones or strong accents become the buyer's problem
Setup & Integrations
Technical difficulty
Low for normal use. Running a study needs no technical skill: you write a discussion guide and share a link, which Tellet describes as being as simple as sending a link, with analysis triggered in one click. Everything runs in a browser, with no API or SDK to integrate and nothing to install. Tellet Embed asks slightly more, pasting an iFrame snippet into an open-ended survey question, which is light technical work rather than development. The main friction is not the product but the missing user documentation: the published guide pages do not load.

Should you pick Tellet?
Tellet does one thing and says so plainly: it turns qualitative interviewing into something you can run at survey scale. The AI moderator, the real-time probing, the multilingual reach and the ability to re-question a transcript corpus months later add up to a coherent product rather than a demo, and named references such as Vodafone Ziggo, Royal Swinkels and Blauw research suggest it survives contact with established insight teams.
Its data posture is stronger than much of this market. Tellet runs on Azure OpenAI and states that no model is trained on customer data, interview data is held on EU servers, a Data Protection Officer is named, and respondents give explicit consent before an interview begins. That last point matters more than it looks, because this tool processes the personal data of third parties who have no account with the vendor and no commercial relationship with it.
The reservations are commercial and documentary rather than technical. There is no API, no mobile app, no free plan and no trial, and the real entry cost sits well above the headline EUR 25 per interview once the EUR 750 platform fee is added. ISO 27001 is advertised as coming rather than held, no DPA or subprocessor list is published, and retention is described only as as long as necessary. Site upkeep is uneven too: the cookie policy and the user guides do not render at all, and the link to the general terms returns a 404.
For a young company funded on a EUR 400,000 pre-seed, this is a credible product whose paperwork has not yet caught up with it.
