Deep Water

Deep research infrastructure. Built in Europe.

Research you can
prove and control.

Deep Water researches across 83 languages, checks every citation against the source it came from, and gives you a report with the evidence attached.

−300 m — the problem

AI sounds sure of itself.
That doesn't make it right.

Most AI reads a few web pages and stops. Five or ten pages, in English, whatever came up first — then it tells you the answer like it's certain. Everything else stays unread: the papers, the PDFs, and anything not written in English.

−700 m — the sweep

We check every citation. Then we remove what does not hold up.

Before a claim reaches the report, we read its cited page again. If the page does not support the claim, the claim is removed. Keep scrolling — the light is passing over the sources now.

Every cited claim shows you where it came from.

Browser-native compute matured sharply this year, with workgroup memory limits raised across all three major engines and a common subset finally shipping by default.12

Independent benchmarks recorded a median 3.1× throughput gain on fused kernels against the 2024 baseline, holding across discrete and integrated hardware.07

Adoption stayed gated by driver parity on mobile, where two vendors still trail the specification by a full release and expose only a reduced feature set.23 31

Japanese conformance testing surfaced a regression that no English-language source reported — モバイルGPUドライバの適合性に回帰が確認された — filed against two shipping driver builds.23

German trade press put the driver gap at two release cycles, which the vendors have not disputed publicly, though neither has committed to a date.44

Chinese developer forums report the same regression reproducing on three mid-range chipsets, with a workaround that costs roughly 18% of the gain.52

Patent filings from one vendor describe a scheduler change that would close the gap, but the filing carries no ship signal.61

Where the record is thin, the report says so instead of filling the gap: no source we could verify reports shipped hardware using the new limits in production.08

Some teams report much larger gains. could not be verified · dropped

−1,500 m — how deep do you want to go?

104 sources in this run

You choose how deep we go.

You pay for the work you order, not per person. Deeper means more sources, more time, and more cost. Pick a tier — the sediment on the left is every source that run would read.

An agent that ships work needs to know how it's done today.

Most guess from training data. What works now, what failed last year, what's different in Germany than in Japan — none of that is in there.

We do the reading first. Your agent gets facts with sources attached, before it starts working.

−4,100 m — the lamp turns on us / for researchers and scientists

Nothing here is hidden from you.

83 languages01 / 06 We read in 83 languages, not just English. Sources remain linked from the report.
Source type02 / 06 University, government, company, news, social media — written next to every citation.
OCR03 / 06 Scanned PDFs get read too, page by page.
Disagreement04 / 06 When sources disagree, we say so. We don't quietly pick something in the middle.
Reverse check05 / 06 Every citation is read back against its source. What doesn't hold up gets dropped.
Still there06 / 06 Published reports keep their source lists, so you can return and check them later.

−4,700 m — public or private

You decide who sees it.

Reports you choose to publish appear in our open library. It is free for anyone to read, so you can inspect dozens of complete reports and thousands of linked sources before you run your own.

If the finished report must stay inside your team, private research is available as an optional add-on. Private reports are not published to the open library; your Billing view shows the current offer and eligibility.

−5,100 m — price

You pay for the work you order.

Not per person. Your team shares one pot of credits, and 1,000 credits is one dollar. A short report costs a little. A deep one costs more, because it reads more.

Before you start, we tell you how long it will take. You are charged for what the run actually used.

Everyone on your team can see what's left.

What every run includes

01 · Before

You choose the depth.

We show a time estimate before you start. The run begins only when you confirm it.

02 · After

You get the evidence.

Your report includes inline citations and a linked source list, not a bare answer.

03 · Control

You choose who sees it.

Publish to the open library, or keep the report inside your team with private research.

−5,600 m — questions people ask

Q.01

Is it really checking, or just guessing better?

Every citation gets read back against the page it came from. What doesn't match gets dropped before you see it.

Q.02

How is this different from Deep Research in a chat app?

A chat app's Deep Research answers a prompt inside that product. Deep Water is the research infrastructure underneath: it scopes the question, gathers and structures evidence, writes from that evidence, and checks cited claims back against their sources. Use it here, or connect the same research layer to your own product or agent. The API and alpha CLI are available today; MCP is in private beta.

Q.03

How long does one take?

A quick one takes minutes. The deepest one takes a lot longer, because it's reading hundreds of pages. We show you the estimate before you start.

Q.04

What if I don't speak the language of the source?

We translate it for you and keep the original next to it, so you can always check.

Q.05

Can I see it before I pay?

Yes. Our open library contains complete reports that are free to read. Open one and click through the sources yourself.

Q.06

What can't it do?

It doesn't watch videos or listen to podcasts. It reads text — web pages, papers, and scanned PDFs.

The people behind Deep Water

Two brothers.
One standard: show the work.

We are brothers Jakub and Ondrej Rafaj. Our backgrounds span technology, product, UX, and design. We built Deep Water because research is only useful when another person can inspect how you reached the answer.

At this stage, questions go directly to the people building the product. If you have a hard question before you start, write to us directly.
