Know the truth before you publish.
One fabricated citation. One unsupported number. One claim that contradicts what you published last month. Once it goes out under your name, the error travels further than the work. Ukweli pressure-tests the document first.
Invite-only Early Access · Opening market by market
Every analysis returns one verdict — with the evidence attached. Here is Ukweli's result on a sample company prospectus that reads clean but isn't:
AI made content cheap and fakery invisible. It didn't make you any less accountable for what goes out under your name. Ukweli pressure-tests a document against up to eight integrity checks and returns one verdict — so “we checked it” stops being a claim and becomes a record.
A national AI policy was withdrawn over citations that did not exist.
South Africa's Department of Communications and Digital Technologies withdrew its Draft National AI Policy after its reference list was found to contain fictitious, AI-generated citations. The fabrication became the headline — not the policy.
Source ↗Every one of these was a checkable citation. A structured pre-publication integrity check verifies each reference against the live record — and catches the invented ones before the document leaves the building. That is what Ukweli does.
A verified, sourced record of AI-fabrication incidents · updated weekly · free dataset
A verdict you can act on, with the evidence attached.
Every analysis returns one of three verdicts — Cleared, Review required, or Hold — with the specific findings that drove it: the claim that is unsupported, the statistic that does not reconcile, the source that could not be verified. If the verdict is Hold, it says Hold. The honesty is the point.
The name is the promise.
Ukweli (oo-KWEH-lee) is the Swahili word for truth. It is not a coined tech name — it is an African word that means exactly what the tool does. We use it with that weight.
Fabrication has become cheap and fluent. A citation that was never published, a statistic with no source, a claim that contradicts last quarter's report — all of it now reads as clean, confident prose. Editorial review was built for honest mistakes, not for machine-generated plausibility. Ukweli is the check that sits between the draft and the world.
What Ukweli is — and what it is not.
- Reads the whole document, not a sample.
- Checks editorial integrity and the precision of every claim.
- Audits the numbers and reconciles figures that should add up.
- Verifies citations live, against the real record.
- Screens sensitivity, research method, and consistency with your own past work.
- Returns one verdict — Cleared, Review required, or Hold — with the evidence and a statement of what was and was not checked.
- Not a plagiarism checker.
- Not an AI-content detector.
- Not a grammar tool — it goes deeper than wording.
- Not a replacement for editorial judgement. It supports the people who hold the standard.
- Not a guarantee of perfection. It assesses integrity against the checks that ran — not a substitute for legal, financial, or regulatory sign-off.
Comparing Ukweli to a tool you already use?
Those tools ask was this machine-written, and was it copied? Ukweli asks whether what it says is true, precise, and defensible before you publish. Where there is a real overlap, we say so.
Choose a tool…TurnitinGPTZeroCopyleaksOriginality.ai
Turnitin asks where a document came from — whether it was copied, and how much of it reads as AI-written. Ukweli asks whether what it says is true: precise, sourced, and defensible, before you publish it.
Full comparisonGPTZero detects AI-written text and, with its hallucination check, verifies whether the sources a document cites actually exist. That second part is a real overlap with us. The difference is where it stops: GPTZero says its tool does not judge whether the claims themselves are true or false. Ukweli does — it checks whether the source supports the claim attached to it, reconciles the figures, and returns one verdict with the evidence.
Full comparisonCopyleaks detects AI-generated and copied text across many languages. Ukweli is not a detector — it verifies whether what the document asserts is actually true and supportable, then returns one verdict with the evidence.
Full comparisonThis is the closest overlap. Alongside AI and plagiarism detection, Originality.ai also includes an AI fact-checker. The difference is depth: its own guidance presents it as a “fact checking aid” and tells you not to treat it as the final word. Ukweli reads the whole document across up to eight integrity checks — claim precision, figure reconciliation, citations verified live against the public record, sensitivity — and returns one verdict with the evidence and a statement of what was and was not checked.

Whichever tool you have in mind, Ukweli is a pre-publication screen, not a guarantee, and not a substitute for legal, financial, or regulatory sign-off.
Built for the documents that carry your name.
Any text-based document where claims, figures, and citations carry weight. Ukweli reads PDF, Word, or pasted text — not spreadsheets, images, or raw data.
The cost of producing convincing content just hit zero. The cost of publishing something false didn't. Ukweli is the check between the two.
What an integrity check actually catches.
A real example: the withdrawn national AI policy
When South Africa's Department of Communications and Digital Technologies published its Draft National AI Policy in 2026, the reference list cited sources that did not exist — authoritative-looking citations that resolved to nothing. The policy was withdrawn, and the fabrication became the story.
Here is the part that matters: every one of those sources was checkable. Ukweli's citation verification takes each reference, looks for it in the live public record, and returns the ones that cannot be confirmed — before you publish, not after the correction.
A sample you can run yourself
Ukweli ships with a fictional company prospectus — “Meridian Labs” — that reads like clean, confident marketing. Ukweli holds it anyway, and shows every reason: a no-bias promise that contradicts a guaranteed rating for paying clients, headline figures with no source, an overstated accreditation claim, and a named expert whose credentials don't check out.
A spotless-looking document — held, with every reason attached. Run it and see the full report.

Questions people ask before they trust it.
Privacy & your data
Is my document stored?
No. Ukweli analyses your document in memory and does not retain it — your text is discarded after the run. It keeps only the structured result (the findings and verdict), for up to 90 days, and you can delete that at any time.
How is my document kept confidential?
Confidentiality starts with not keeping your document at all: it is analysed in memory and discarded the moment the run finishes — never written to our database or disk, so nothing is stored that could leak. In transit it is encrypted (TLS); the structured result is access-controlled to your account; and we never sell or share your content. The few providers that help run the analysis receive only the minimum needed and are bound by data-protection terms. Full detail, including cross-border processing, is in our Privacy Policy.
Will other users see my documents or my reports?
No. There is no document for anyone to see — we do not store it — and your reports are visible only to your own account, protected by sign-in and per-account database access controls. Your content is never compared against, or shown in, the analysis of any other customer. The one exception is inside your own account: if someone on it runs a Tier 3 (Certify) analysis and switches on the "Check Against Past Documents" option, the new document is checked against the positions from your earlier cleared documents — never the documents or reports themselves, and never across accounts.
Does Ukweli use my document to train AI?
No. Ukweli has no model that learns from your content, and we never repurpose your documents for training or marketing. Your document is processed by our AI provider (Anthropic's Claude) only to produce your result; under Anthropic's API terms, content sent through the API is not used to train their models. Our current providers and their commitments are listed in our Privacy Policy.
What do you do with my account details?
We keep two kinds of data strictly separate. Your documents are processed in memory, never stored, and never used for anything beyond producing your result. Your account and contact details — name, email, organisation, role, and country — are used to run your account, manage our relationship with you, and send service and product updates, including telling you when Ukweli opens in your market. We do not sell your information, and you can opt out of non-essential messages at any time. Full detail is in our Privacy Policy.
Does Ukweli judge my organisation’s — or anyone’s — reputation?
No. Ukweli assesses a document’s integrity, not anyone’s reputation, and it works only from what you give it — your document, any primary source you attach, and, on Tier 3, your own earlier cleared documents if you switch that on. It does not search the open web for, or form a view on, the standing of any brand, organisation, or person. Where it raises a reputational angle at all, it is limited to flagging where your document departs from positions you published before — to protect you from contradicting yourself in public — never an outside verdict on you or on a third party.
Verdicts & the certificate
How accurate is it — can I trust the verdict?
Ukweli shows its evidence for every finding and states plainly what it did and did not check (the coverage statement). The verdict is rule-driven, not a guess. It is a pre-publication screen, not a guarantee of completeness — high-stakes documents should still get human sign-off.
What do Cleared, Review required, and Hold mean?
Cleared: no blocking issues against the checks that ran. Review required: fixable issues to resolve before publishing. Hold: at least one serious problem makes it unsafe to release as written. The verdict is the decision; the score is a resolution meter, not a grade.
What does an Integrity Certificate actually attest?
It records that, at the time of the check, a Tier 3 (Certify) analysis ran the full set of checks — including live citation verification — and returned a Cleared verdict, with the evidence attached. That is what the seal stands behind: every checkable claim, figure, and citation was tested against the available evidence, and nothing failed. It certifies integrity, not omniscience — Ukweli holds a document to the truth standard, it does not declare a document beyond question. It can only test what is checkable against available sources, so the seal does not stand in for matters of opinion, predictions, or facts no source can confirm, and it is not an endorsement of the author, a warranty of legal compliance, or a form of regulatory approval. A certificate is only issued when those checks actually ran: if live citation verification could not run, the document downloads as a plain report rather than a sealed certificate. High-stakes documents should still carry human sign-off.
Why isn’t the goal a score of 100?
Because 100 would imply a guarantee of perfection Ukweli refuses to make. The number is a risk-and-resolution meter and a draft-over-draft tracker; the threshold that matters is the verdict, not the score.
Scope & usage
Is this a plagiarism or AI-content detector?
No. Those ask whether this was machine-written, and whether it was copied. Ukweli asks whether what it says is true, precise, and defensible — claim precision, figure reconciliation, live citation verification, and sensitivity.
Does it replace my editor, lawyer, or compliance team?
No. It is decision-support that catches what a fast human read misses, before a document goes out under your name. It is not a substitute for legal, financial, or regulatory sign-off.
Which documents can I check?
Any text-based document where claims, figures, and citations carry weight — strategy documents, proposals, policy documents, white papers, research, reports (monthly to annual and board), press releases, speeches, thought-leadership, grant applications, board papers, ESG and investor updates, tender responses, and prospectuses.
What file types does it take?
PDF, Word (.docx), or pasted text. Ukweli reads prose — it is not for spreadsheets, images, or raw data.
