Each margin note, structural suggestion, or stanza audit is an atomic payment, ensuring poets and editors are compensated instantly for their intellectual labor. No more free 'looks'—professional eyes for micropayment prices.

The primitive.

full primer →

Access to the peer feedback engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so writers — or the agents working for them — pay per query and get a HashScan receipt every time.

Why this primitiveFeedback loops in creative writing often suffer from a 'labor for exposure' trap. By turning every critique into an HTS transfer micro-settlement, we quantify the value of peer review. x402 eliminates the friction of bulk subscriptions, allowing writers to pay only for the feedback they consume while building a reputation-backed revenue stream for editors.

poetry archiving
VerseLedger · x402
A granular attribution layer for poets. Instead of a one-time mint, VerseLedger meters the "Proof of Originality." Pay 0.01 USDC to cryptographically timestamp a stanza or signature, or 0.01 USDC to query the chain for a similarity check against the ledger. It turns the archive from a static list into a pay-per-verification utility for publishers and literary scouts.
interactive storytelling
PlotLine · x402
A real-time collaborative logic engine for fiction where every narrative branch is a pay-per-vote micro-transaction. Authors publish 'Fractured Chapters' where the plot path is gated by liquidity; the story only progresses when the collective pool for a specific outcome hits its threshold. 0.01 USDC per vote ensures skin in the game while preventing bot-spamming of plot arcs. Readers don't just consume; they fund the creative direction one sentence at a time.
screenwriting rights
DraftFlow · x402
A granular narrative licensing engine where screenwriters monetize at the scene level. Producers and AI pre-viz tools pay 0.01 USDC to 'Read & Reference' specific plot points or dialogue blocks. Each interaction triggers an HTS transfer transfer directly to the script's contributors, turning a static PDF into a metered IP asset. Payment is the permission layer for adaptation.
