02 The story — why this matters now

In the age of AI, trust doesn't scale. Proof does.

  • We used to assume that if something was written down, someone had checked it. That assumption is gone.
  • AI now writes a paragraph, builds a chart, renders a whole video in seconds — confidently, and sometimes completely wrong. It makes things up and states them like facts.
  • We've flipped from a world where content was expensive and mostly checked, to one where content is free and mostly unchecked. Making content isn't the hard part anymore. Trusting it is.
  • Everyone's answer so far is to catch the fakes after they're out — better detectors, better fact-checkers. It's a losing race; the fakes get better every month.
  • Sourceal takes the other road: instead of chasing bad content after it ships, it makes sure only sourced, proven content gets made in the first place.

"Trust me" doesn't hold up anymore. Proof does. That's what we build.

03 How it works

Three steps, and a wrong number never gets in.

  1. 01

    Your sources in

    It starts with your sources — the filings, data, and research your content is built from.

  2. 02

    Checked, sealed, proven

    Each number is checked against where it actually came from, noted with its source and date, and locked so no one can quietly change it later. If a number can't be traced to a real source, it simply doesn't make it in.

  3. 03

    Finished content out

    Your sources become finished content — videos, slide decks, and social carousels — with every fact already sourced and sealed.

04 The receipt

A record of where every fact came from.

You get a simple receipt for each piece of content showing where every fact came from — so when someone asks "where did you get this?", you already have the answer.

A proof receipt for every asset, showing the source, date, and origin behind each fact — ready to hand to a client, editor, auditor, or reviewer.

05 Where it fits

Five places one wrong number costs you.

01

Finance & investment

Where it fits Drop in the filing or factsheet, and the client email, chart, or ad comes out with every number already sourced and sealed.

The problem

One wrong number in a chart or an ad can cost you a client, or worse. Today a person checks every figure by hand — slow, and people miss things.

It really happened

In 2010, two famous economists published that once a country's debt passes 90% of its economy, growth falls off a cliff. Governments used it to justify years of budget cuts. Three years later a student found the spreadsheet behind it had accidentally left rows out of the math — and the cliff wasn't real.

How Sourceal would've helped

Every number would be tied back to the original data and checked as the report was built, so the missing rows get caught before publishing — not three years later.

What you walk away with

Content you can publish without holding your breath, and a record of where every number came from.

02

Legal

Where it fits Every citation in the memo comes back checked and traceable, before it reaches a partner or a judge.

The problem

A brief or memo is only as strong as the sources behind it. A citation that falls apart can sink your credibility.

It really happened

In 2023, New York lawyers filed a court brief citing several past cases to back their argument. ChatGPT had invented those cases — they didn't exist — and the lawyers were sanctioned and fined $5,000.

Source: Wikipedia — Mata v. Avianca

How Sourceal would've helped

Every citation has to trace back to a real, checkable source before it can go in. A made-up case has no source, so it never makes it into the document.

What you walk away with

Work that holds up under scrutiny, with a record behind every fact.

03

Creators & educators

Where it fits Feed it your research doc, and your script, thumbnail stat, and carousel come out with sources attached.

The problem

Your audience trusts you. One unchecked stat and a community note (or a comment pile-on) can cost you that trust.

It really happened

For years, creators and even Microsoft's marketing repeated that people now have an attention span of 8 seconds — shorter than a goldfish. When the BBC dug in, the number traced back to a website that couldn't show any real study behind it.

Source: Fast Company · Forbes

How Sourceal would've helped

It would've asked for the source of the "8 seconds" claim while the video was being built — and with nothing real to point to, the stat wouldn't have made the cut.

What you walk away with

Content you can publish confidently, with sources ready if anyone asks.

04

Consulting & analysts

Where it fits Point it at your data room, and the deck builds with every figure tied to its source, ready for the client Q&A.

The problem

Your deck is your reputation. A number a client can't verify undermines the whole recommendation.

It really happened

In 2012, a major bank tracked a huge trading risk in a spreadsheet with a formula mistake that made the risk look far smaller than it really was. The bank went on to lose around $6 billion.

Source: Forbes

How Sourceal would've helped

Every number in the model is tied to its source and checked as the report comes together, so the slip gets flagged before anyone relies on it.

What you walk away with

Decks where every number is defensible on the spot.

05

Marketing & comms

Where it fits Give it the research behind the campaign, and every claim ships already backed.

The problem

Customers and competitors fact-check your claims. One shaky stat and the whole message loses credibility.

It really happened

An energy-drink brand ran ads promising focus and performance boosts it couldn't back up with scientific evidence, and in 2014 paid about $13 million to settle a false-advertising case.

Source: CBC News · Truth in Advertising

How Sourceal would've helped

Every claim in a campaign needs a real source before it ships — a promise with nothing behind it doesn't go out.

What you walk away with

Campaigns that stand behind every word.

06 The moat

Different by architecture, not by a better filter.

Prevention, not detection

Everyone else checks content AFTER it's made — fact-checkers, AI-detectors that guess with a probability. Sourceal makes it impossible for an unsourced claim to be in the content in the first place. That's a different architecture, not a better filter.

Verify without trusting us

The proof receipt can be checked by anyone — a client, an auditor, opposing counsel — using cryptography, not our word. "Don't trust us, verify" is a guarantee the "trust our AI" tools simply can't make.

Fail-closed by design

If a fact can't be proven, the content doesn't render. It's a hard architectural rule — not a setting someone can switch off or forget to turn on.

One guarantee, every format

The same proof holds whether the output is a video, a deck, or a carousel. Binding verifiable proof to finished creative content (not just a text file) is the hard part — and we did it.

Standards-based, not a walled garden

Built to align with open content-provenance standards (like C2PA / Content Credentials), so the proof travels and interoperates.

The receipt IS the product

Competitors sell a tool. We ship an artifact — a signed, tamper-evident record — that a compliance team, an editor, or a court can actually file.

07 Why this isn't a one-day project

Hard to build on purpose.

  • The easy part is a form and an AI writer. Anyone can build that.
  • The hard part is the verification pipeline: breaking content into individual claims, binding each one to a real source, sealing it cryptographically, enforcing fail-closed rendering across video, decks, and carousels, and producing a receipt anyone can verify without trusting us.
  • And that difficulty is the whole point: if anyone could fake the proof in an afternoon, the proof would be worthless. Sourceal is hard to build on purpose — that's exactly what makes it worth trusting.

08 Security & cryptography

Proof you can't fake, on content anyone can check.

Here's how Sourceal is built — by design.

In plain words
  • Every fact gets a tamper-proof seal showing where it came from and when.
  • Change the content or the source even slightly, and the seal breaks — so you can always tell if something's been altered.
  • Anyone you share it with can check the proof themselves. They don't have to take your word for it — or ours.
  • Your sources and data stay encrypted and private, and we never reuse them to train anything.
The detail
Cryptographic source-bindingby design
At the moment a source comes in, each claim is bound to a fingerprint (hash) of that source — a verifiable link between the fact and its origin.
Digitally signed, tamper-evident receipts
Every asset ships with a signed proof receipt; any change to the content or its sources invalidates the signature.
Trusted timestampingby design
Each source and claim is timestamped, so the "as of" date is provable, not just asserted.
Immutable provenance log
A hash-chained, append-only record of every source, claim, and decision — a full chain of custody you can audit.
Independent verificationby design
Receipts are checkable by third parties with standard cryptography — no need to trust Sourceal's servers.
Standards alignment
Designed to interoperate with open provenance standards (e.g., C2PA / Content Credentials).
Data protection
Encrypted in transit and at rest, scoped access controls, and a no-training-on-your-data policy.

11 FAQ

Common questions.

What is Sourceal?

Sourceal turns your sources — documents, filings, transcripts, data — into finished video, decks, and carousels, with every fact bound to its source and a verifiable receipt attached. Think of it as a content engine with provenance built in.

How does the proof receipt work?

As Sourceal builds your content, it records where each fact came from and seals that record. The result is a receipt anyone can check — the figure, its source, and when it was verified — so your audience doesn’t have to take your word for it.

What can Sourceal create?

Short-form and long-form video, slide decks, and social carousels — all from the same sourced, sealed material, so every format carries the same guarantee.

How is this different from fact-checking or AI-detection tools?

Those work after the fact. Sourceal is prevention, not detection: it binds facts to their sources as the content is built, so a wrong number never makes it in — instead of trying to catch it afterward.

Do I have to trust Sourceal?

No — that’s the point. Sourceal is built so its output can be verified independently, against open standards. Made to be verified, not trusted.

When can I get access?

Sourceal is in pre-launch. Join the waitlist and you’ll be first to hear when early access opens — launch news only, no spam.
