Built to be checked, not trusted

Everything here is shipped and running, or openly marked as not. The company's own record of each one — what it is, who it is for, and what it is allowed to do with your data — is at dooplin.com; this page is my part in them.

Cognoir

Answers grounded in your own documents, cited to the source

Cognoir: Your documents → Isolated tenant index → Cited answer. Denied route: Model training. Tenant documents never train a model.

A multi-tenant retrieval-augmented generation platform for teams that need language models grounded in their own documents. One deployment, isolated data per customer: ask in plain language, and the answer is cited back to the source it came from.

My part: I design and build it: the architecture, the retrieval and citation pipeline, the tenant isolation model, and the infrastructure it runs on.

Sitr Shield

A halal content filter that can't spy on you

Sitr Shield: Your browser → On-device filter → The page you asked for. Denied route: Our servers. Browsing history never reaches us.

A content filter for a community that shouldn't have to trade surveillance for the feature. The mechanism is the promise: filtering is evaluated on the device, so there is no browsing history on our side to collect, sell, or leak. Available now as an open-source Chrome extension; iOS and Android apps are in development.

My part: I build the extension and the filtering engine, and I decide what it is allowed to see — which, by design, is nothing.

Oldspeak

Every outlet's headline on the same event, side by side

Groups how more than two hundred Bangladeshi, South Asian and international outlets headlined the same story, and scores one article per story for bias on a fixed, published seven-gate rubric — so the same article always gets the same score. For anyone who wants to see the framing, not just the news.

My part: I design and build it.

July Archive

The primary record of Bangladesh's July 2024 revolution

July Archive: Primary sources → Bilingual archive → Any reader. Denied route: Account wall. Reading the archive requires no account.

A bilingual public archive of the thirty-six days that toppled a regime — documents, photographs, testimony and broadcasts, preserved as primary sources with citations, with open API access for researchers and answers drawn only from the published record. It earns nothing, costs money to run, and is built to outlast the company. History that isn't archived gets rewritten; this is my part in making that harder.

My part: I built and run it. It is not a product: it is where our web-archiving work was built and proven.

Tillo

A VERI*FACTU-ready point of sale for Spanish shops

A marketing team member that asks before it posts

On what is not here

One more product in development is deliberately absent — no name, no placeholder — until it has a public name and a confirmed retention policy for the location data it will necessarily handle. That is the company's rule for its own site and it is a good one: announcing a thing that touches people's movements before deciding what it may remember about them is how you end up defending a decision you never actually made.

The same rule covers what is here. A product's data claim appears on this page only once the company has confirmed it for publication — a draft is not a claim. The full register is at dooplin.com/products.
