A review discipline, not a feed

01

Import your universe

CSV or JSON, by file or paste. Every row is validated and the import ends with a receipt: accepted, rejected with reasons, adjustments listed. Nothing in your data is changed.

02

Review with discipline

The Stack tells you what changed and what to open next. Work each evidence file: review, watch, snooze (returns later), set aside (parked, not deleted). Notes stay on the record.

03

Keep the Brief

Export a Daily Brief — a printed front page of your research state: what changed, top of the queue, your watchlist. Sample data is stamped as sample data.

Inside the console

Evidence, freshness, coverage — computed from your own records

Block strips. The Stack opens on a compact, block-level decision surface — coverage, freshness, attention and a trajectory sparkline per Block. No market table, no noise.
Evidence coverage matrix. Records × evidence fields, with orange-ringed gaps. Gaps lower Data Coverage — you see exactly where the work is.
Evidence File. Each record opens to a rich instrument band — Research Direction, confidence, a trajectory and factor read, evidence balance, notes and a provenance chain of custody.
Decision Log. A dated ledger of every review action, kept locally. Research history — not a trade record.
Signals. Research dispatches — high risk unreviewed, check date passed, stale review, evidence gap. Items worth reviewing, never instructions to trade.
Block Intelligence Console. Each Block opens on a charted console — coverage & freshness rings, attention pressure, an interactive factor profile, and top research targets with trajectories.

FAQ

Plain answers

What exactly do I get for $27?

The full QuantBlocks console as a single HTML file. Open it in any modern browser — no installer, no account, no subscription, no expiry. It includes the complete My Data workflow: CSV & JSON import with a receipt, add/edit/archive, exports and the Daily Brief. Your data stays in your browser unless you export it.

Does it connect to my accounts or place trades?

No. QuantBlocks never connects to a brokerage, never places trades, and never gives buy/sell signals. It is a research organisation tool: it helps you review your own work.

Is my data private?

Yes — structurally, not by promise. The app makes zero network requests. Open DevTools and watch: nothing leaves your browser. Your records are kept in local browser storage and in the files you export.

What file formats work?

CSV (with a header row) or JSON — a QuantBlocks JSON export round-trips straight back in, provenance included. Import by file or paste. Every import ends with a receipt.

What is a Signal here?

An item worth reviewing — high risk and unreviewed, a check date passed, a stale review, an evidence gap. Signals are never instructions and never predictions.
