Rahul writes a weekly crypto newsletter full of calls. Calibrated stores each call with a date and resolves it later, so readers see he is right 68 percent of the time at stated confidence, and he grows on honesty instead of hype.
Call creation with confidence, timed resolution by owner plus reader dispute, Brier score profile, embeddable widget.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Onchain Brier scoring exists for agents; an owned calibration profile for any human expert is the uncommon angle.
Pantheon (Casper hackathon) and Foresight Arena score AI forecasters onchain with Brier scores; Metaculus and Good Judgment score humans on their own platforms.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
Retroactive for shipped Base apps.
The complete Calibrated app: writers seal every call with a confidence, a source and a date, readers see one honest score, with a paywall, reader disputes and a resolver agent built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Writers seal, resolve and show their Brier score for free. Serious writers pay for Pro tools, and publications pay for many writers under one masthead.
Gas is under 2 cents per sealed and resolved call and can be sponsored by the owner. Payments settle in USDC on Base by default.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $1,500: your own resolution source adapters, a branded publication deployment, CMS integrations beyond Substack and Ghost, or extra languages. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Newsletter writers, analysts and creators make public predictions every week, but nobody keeps an honest score. Misses get deleted or forgotten and hits get repeated. Readers cannot tell a careful thinker from a loud one, and honest writers have no way to prove they are careful.
Scoring forecasts is not new. Metaculus and Good Judgment score human forecasters with Brier scores, but only on their own platforms and questions. Pantheon (a Casper hackathon project) and Foresight Arena score AI forecasters onchain with Brier scores. Research verdict: rare, medium novelty. What this app adds is an owned calibration profile for any human expert, on their own calls in their own newsletter, with calls sealed onchain before the answer, reader disputes, and an embeddable widget. It applies known scoring to a new audience rather than inventing the scoring.

Let anyone who makes predictions build a track record they cannot quietly edit, and let readers trust people for being right rather than loud.
One honest number When I say 70%, I am right 68% of the time. A single, checkable line that careful writers love to share.
Friday resolution day Every Friday the due calls resolve. Readers come back to see who was right, and can score their own guesses against the writer.
Misses that stay Wrong calls stay on the page, struck in red. It sounds like a downside; it is exactly why readers believe the hits.

Cost per use: unlocked when your app is paid in full.
Writers share their calibration line and embed the widget in every issue. Readers who score their own guesses on Friday become writers themselves. A good score is a reason to send traffic; a public profile is a quiet challenge to rivals.

Costs and tools are estimates at the time of writing. General information only, not legal or financial advice.
Nine routes from one vessel. Tap a port to open its chart.
Calibrated turns every call you make into a dated, resolved record that lives at your own address, under your own name. On someone else's platform your track record belongs to them and disappears when you leave; on yours, your hit rate is a public asset that follows you to every newsletter, podcast and job. Readers stop asking whether you are loud and start seeing whether you are right.
Then you learn it before your readers do. Run it privately for four weeks, look at your Brier score, and only publish the widget once you are comfortable. A 60 percent hit rate shown honestly beats a 90 percent claim nobody can check, and the score rewards stating lower confidence when you are unsure.
You do not need to. You create a call in a form, pick a confidence, set a resolution date, and resolve it when the date arrives. The embeddable widget is one line you paste into Substack, Ghost or your site builder, and DEPLOYR ships it set up.
You resolve it, and readers can dispute. Every resolution and dispute is recorded, so cheating on your own calls is visible to everyone. Pick a clear resolution source when you write the call (a price feed, a public announcement, a named date) and disputes stay rare.
Yes. The contract deploys from your wallet and the calls are signed by you. If DEPLOYR vanished tomorrow, your record would still be readable onchain and you could point any frontend at it.
Calibrated records predictions, it does not give advice or take money for trades. Still, if your calls are about assets, add a plain not financial advice line and check your local rules on paid signals before you charge for them. Many owners avoid this entirely by calling events, launches and metrics instead of prices.
Calibrated earns in three ways: a paid tier for your readers who want early access to calls before they go public, a hosted version you rent to other writers and analysts who want their own score, and sponsorship from tools that want to sit next to a verified track record. This is a target to aim at, not a promise.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
