Attesté — Your art, connected. Art certificates, provenance & AI

From studio to wall, and onwards

One place for the whole life of a work of art.

Make it, buy it, hang it, lend it, pass it on. Attesté keeps the record straight at every step, so the story of a work never depends on someone finding the right email.

Prove.

A certificate anyone can check

Every work gets an Attesté certificate, signed when it’s issued and timestamped on Bitcoin. Share the link or the QR code; whoever opens it sees whether the record still matches, with no account and no app.

Own.

The paperwork, finally in one place

Invoices, condition notes and valuations live with the work they belong to. When the insurer asks, you export one tidy PDF instead of an afternoon in the filing cabinet.

Show.

Out in the world

Artists get a public page at atteste.art/artist/their-name, with their works and certificates on it. Galleries get a place in the gallery directory inside the app, where collectors browse before a Saturday of gallery-hopping.

Pass it on.

The record travels with the work

Sold, gifted or consigned, the work’s record moves to its next owner, and every hand-over is signed and added to the chain.

Talk.

From the AI you already use

Plug Attesté into any assistant that supports MCP, paste a certificate link, and ask. It checks the signature, the Bitcoin timestamp and the ownership history for you, and says plainly what that does and doesn’t prove.

The Trust Gap

Art still changes hands on a PDF and a promise

Thursday, 21:40. A collector is about to pay for a painting they first saw on Instagram. What they have to go on: a “certificate of authenticity” someone made in Word, a long WhatsApp thread, and bank details for a person they’ve never met. Pay, and hope.

Attesté closes that gap one work at a time. Its certificate is signed when it’s issued and timestamped on Bitcoin, so anyone can check that the record still matches what was signed and that it existed before a specific block. When the work moves on, the record goes with it.

“Can you send the certificate?”
“Sure, I’ll WhatsApp it.”

How It Works

Three Steps to a Living Collection

From gallery floor to generational legacy — Attesté turns every encounter into documented history.

Encounter

See something you love? Photograph it. Our AI identifies the artist, medium, and period instantly. Log the encounter — where you saw it, how it made you feel. Every gallery visit, every fair, every studio becomes part of your story.

Document

Build a living record of your collection with cryptographic integrity. Upload invoices, track condition, generate certificates. Whether it's your first print or your fiftieth oil painting — every piece deserves provenance.

The Signature Experience

Stand Before a Work.
And Simply Ask.

Atelier is a voice-first AI companion that sees what you see. Point your camera at a painting and talk — about the brushwork, the period, the provenance. It answers aloud, in your language, grounded in your collection's own records.

YouWhat am I looking at here — this ridge in the paint, near the horizon?

AtelierThat's palette-knife impasto — Wenning built his dusk skies in layers. Your acquisition note places this work in the 1918 Cape series, bought at Everard Read.

YouKeep that with the painting.

AtelierSaved to the journal — pinned to the work, part of its story now.

It sees

Live camera vision. Pan across a canvas and ask about exactly what's in frame — the AI watches with you, in real time.

It speaks

Natural voice conversation about style, technique, history — and your own works' documented provenance.

It remembers

Every session becomes an Atelier Journal entry, pinned to the artwork. Your conversations join the provenance.

Connect your AI

Ask the AI you already use.

Attesté runs a public connector that any assistant supporting the Model Context Protocol (MCP) can plug into. Add it once, then paste a certificate link into the chat and ask away. Your assistant can:

check whether a certificate’s signature holds, and what it records
fetch the Bitcoin timestamp proof, so anyone can check it without Attesté
read the work’s ownership history, shown as roles and dates, never names
explain what all of that proves, and what it doesn’t

Then put it to work. Ask it to draft the caption, the listing or the insurance note, and it writes from the certificate’s facts instead of guessing them. The assistant does the writing. Attesté supplies the truth.

Add a custom connector (MCP server) with this URL:

Read-only. Nothing to sign in to. It can’t see your collection, change anything, or buy or sell. Full setup guide →

YouCan you check this Attesté certificate? atteste.art/v/3PQT…

AssistantThe seal is valid and the record hasn’t changed since it was issued on 31 May 2026. Its fingerprint was timestamped on Bitcoin the same day; here’s the proof file if you want to check it yourself. No change of ownership has been recorded yet.

YouSo it’s definitely by that artist?

AssistantNot from this alone. It’s an artist certificate, but Attesté doesn’t check who opened the artist profile, so it records a claim to be the artist rather than proving it. It also doesn’t say the work is authentic or what it’s worth.

Example conversation, paraphrasing the connector’s real response for a live certificate on 9 October 2026.

The Provenance Promise

Bank-Grade Integrity for Art

Every record in Attesté is secured with SHA-256 cryptographic hashing — the same standard used in financial transactions. Our provenance chain is append-only: records can be added but never altered or deleted.

This isn't blockchain hype. It's the quiet certainty that your collection's story — every acquisition, every valuation, every transfer — is sealed in cryptographic truth. Permanent. Verifiable. Yours.

And our valuation philosophy is simple: invoice is king. AI provides experimental insight, but your portfolio totals only reflect documented, professional valuations. We believe trust is earned through honesty, not inflated numbers.

First Witness. When a work is born in an artist’s studio on Attesté, its chain begins at creation — the artist’s own recorded account, sealed and Bitcoin-anchored as the origin every later record links back to. Provenance written forward, not reconstructed.

Built in South Africa

A father's project became his daughters' business

Attesté started when a private collector realised his children would inherit his art — but not the stories behind it. What began as a weekend project to digitise one collection grew into a platform that could serve every collector.

Today, Attesté is a family enterprise: built by a father, operated by three daughters, and powered by the belief that every art collection tells a story worth preserving.

Our Story

Built for Art. Powered by Integrity.

We didn't set out to build a startup. We set out to solve a real problem for a real collection. That honesty is coded into every decision we've made — from our "invoice is king" valuation philosophy to our append-only provenance chain.

Proven Infrastructure

SHA-256 integrity chain with append-only provenance records. Every record is cryptographically sealed and independently verifiable.

AI That Amplifies, Never Replaces

Dual AI (Google Gemini + Anthropic Claude) provides insight and discovery. But your documented provenance always comes first.

Born in South Africa, Built for Every Collector

Auction intelligence across multiple markets. Discovery trails in cities worldwide. A platform designed for collectors everywhere.

Questions & Answers

Frequently Asked

Straight answers on cost, privacy, provenance, and how the AI works.

What is Attesté?

Attesté is an AI-powered art collection management platform. It helps collectors catalogue their art, verify provenance with SHA-256 cryptographic certificates, discover new galleries and artists via GPS-gated trails, and document collection history across generations.

Can my AI assistant check an Attesté certificate?

Yes. Attesté runs a public, read-only connector at https://mcp.atteste.art/mcp that any assistant supporting the Model Context Protocol (MCP) can use. Paste a certificate link and the assistant can check the signature, fetch the Bitcoin timestamp proof, read the ownership history as roles and dates, and explain what the certificate proves and doesn’t. It can’t see your collection, change anything, or buy or sell. Setup guide.

How much does Attesté cost?

Attesté has a free Explorer tier (25 artworks, 5 AI analyses/month). Paid collector tiers start at $9.99/month (Collector — 200 artworks, full AI Sommelier) and $19.99/month (Premium — unlimited, Legacy Vault), with 17% savings on annual plans. Artist plans start at $14.99/month (Studio, 14-day free trial). Gallery plans are monthly subscriptions sold via the web: Boutique $64.99/mo, Professional $158.99/mo, Enterprise $259.00/mo.

Is my art collection data private?

Yes. By default every collection is private. Public profiles require an explicit opt-in. Data is hosted in Firebase's Johannesburg data centre (africa-south1), so personal data stays in Africa by default. Attesté is POPIA and GDPR aware.

How does AI Art Identification work?

You photograph an artwork with the Attesté app. Google's latest Gemini vision models analyse the image and return likely artist, medium, period and similar works, with an explicit confidence score. Low-confidence guesses are flagged for human verification.

What is an Attesté Certificate?

A SHA-256 cryptographically-secured provenance certificate. It includes the owner, acquisition date and source, a photograph fingerprint, condition and valuation history, and the chain of custody. The hash is published to an immutable log so tampering is detectable.

Does Attesté authenticate whether an artwork is real?

No. Attesté generates a tamper-evident record of what the owner reported. Authentication is a gallery, auction house or expert's job. You can upload professional authentication documents and attach them to the certificate.

Can Attesté help me document an inherited art collection?

Yes. Attesté's AI Art Scout is especially useful for inheritors: photograph each piece and the app identifies likely artist, medium and period. Upgrade to Premium to unlock the Legacy Vault for preserving stories, artist interviews, and acquisition context across generations.

How do galleries use Attesté?

Galleries join on a monthly subscription sold via the web — Boutique ($64.99/mo), Professional ($158.99/mo), or Enterprise ($259.00/mo). They get inventory and exhibition tools, an aggregate collector analytics dashboard, Talking Provenance Curator's Commentary (Professional+), AI-generated exhibition posts, a daily Pulse briefing, the Almanac AI concierge, and a measurable collector pipeline. Analytics are aggregate-only — individual collector data is never shared with galleries.

Where is Attesté available?

The Attesté app works worldwide. POPIA compliance (South Africa) is complete; GDPR compliance (EU) is in progress; US and UK markets are supported. Payment methods vary by region. Contact info@atteste.art for your specific market.

Who built Attesté?

Attesté is built by Yield SPM (Pty) Ltd, founded by Charl le Roux, with its place of business in Stellenbosch, Western Cape, South Africa. Company registration: 2024/185151/07. The same team also operates Practacular, an AI practice management platform for accountants.
