A practical walkthrough of every major capability.

On your first visit, a modal opens with four curated starter portfolios (Magnificent Seven, Dividend Aristocrats, and others) plus a "build your own" picker pre-populated with SPY, GOOG, NVDA. Pick a set or type your own tickers and you are running a real comparison in seconds. You can re-open the modal any time from the small icon in the header.

Each option in the search dropdown shows the symbol, full company name, sector and industry, and a market cap badge across two clean lines. This makes it easy to disambiguate similar tickers (think NVDA vs NVO vs NVT) without leaving the picker. Useful when you only half-remember a symbol but know the company.

A single comparison set can hold up to 100 tickers, well beyond what most charting tools allow. Useful for sector sweeps, watchlists, and "show me everything in my universe" exercises. The chart, table, and metrics stay responsive at this scale because the backend is built around bulk computation.

Every comparison set has a benchmark ticker (default SPY, removable, configurable per set) styled distinctly in the chart and table. The benchmark is what every percentile rank, range band, and SPY correlation uses. Switch it to QQQ for a tech-tilted comparison, or to a thematic ETF if you want a tighter peer baseline.

The main chart supports zoom, pan, and crosshair hover that works across both data points and blank space (so you can read values between bars on intraday views). Drag a region with the mouse to zoom, double-click to reset, and use the range slider underneath the chart for quick scrubbing. This is the core surface for reading shapes: steady climb vs spiky rally vs late-blooming winner.

Switch between linear and log scaling with the segmented control above the chart. Linear suits short windows where absolute change matters; log suits long windows where percentage change matters and otherwise large winners would visually flatten everything else. The toggle changes how a multi-year chart reads.

Every line ends with the ticker label on the right edge of the chart, with smart collision avoidance so labels never overlap. You can read which line is which without dragging the cursor across the chart. Especially useful when comparing 10+ tickers where the legend chips below would be slower to scan.

The fullscreen button (top-right of the chart card) expands the chart to fill your viewport. Useful when you have many tickers and want every line cleanly resolved, or when sharing a screen where the chart needs to fill the room. Press Esc to dismiss.

Choose to show only the top 10, 15, 20, or 25 performers on the chart while keeping the table complete. The chart stays readable when comparing big lists and the table still gives you full context. Useful when 50 tickers turns the chart into spaghetti.

Pick any ticker as the baseline and the chart rebases all other tickers to that ticker's start date. Useful when one ticker started trading later and you want a head-to-head from the youngest start (for example, comparing CRWD to MSFT, where MSFT predates CRWD by decades). Returns and quant metrics recompute automatically against the new window.

When you activate a historical event (like "2022 Bear Market" or "GFC"), a purple chip appears in the chart title showing the event name and date range. You always know what window you are looking at, even after deep zooming or scrolling. The chip clears in one click.

A small panel pinned to the top-left of the chart shows every ticker's return at the current hover x-position, sorted with the leader on top. Walk your cursor along the chart and the panel updates in real time, capping at 30 rows for readability. Useful for answering "who was up the most on this date?".

Hover any ticker chip in the legend below the chart and that line gets thicker while every other line dims. Move the cursor away and the chart returns to normal. Useful for inspecting one line in a busy chart without losing the comparison context.

Shift+click any legend chip to hide that line from the chart. The chip stays in place (dimmed with a dashed border) so you remember it exists and can re-add it with another shift+click. Useful for temporarily removing an outlier so the remaining lines fill the chart vertically.

The legend auto-sorts by the most relevant metric for the current window: CAGR for windows longer than a year, raw period return for shorter windows. The leader is at the top. The default ordering matches the metric that best characterizes the active timeframe, so no manual sort is needed for a quick read.

Hover the small three-bar icon on any legend chip to open a wide per-ticker dossier in place. The dossier shows headline metrics (CAGR, period return, volatility, Sharpe, SPY correlation, trend score) with rank capsules, plus a multi-period returns strip, ATH and ATL info, and the ticker's sector and industry. A complete per-ticker read without leaving the chart.

Every comparison drives a rankings table below the chart, sortable by any column. Click any column header to sort ascending or descending. Use it to move from "show me a chart" to "rank these tickers by Sharpe ratio" in one click.

The Visibility, Rank, and Ticker columns stay pinned on the left when you scroll the table horizontally. You always know which row you are reading, even when comparing wide metric strips on a narrow screen. The sticky band has a subtle shadow so the boundary is visible.

Three toggle pills above the table (Basic, Quant Metrics, Multi-Period) let you show or hide whole groups of columns, each color-coded blue, purple, and green with a live count. Your selection persists across reloads and across comparison sets. Use this to focus on what matters for the question you are asking, without losing the other columns permanently.

The Range column shows a small horizontal bar with a marker indicating where the current price sits between the period's low and high. At a glance you see whether a ticker is near its peak, mid-range, or near its trough for the selected window. Hover for the exact high, low, and current values.

The Multi-Period column shows a small vertical bar chart, one bar per period. Bars are always rendered chronologically (shortest left, longest right) regardless of selection order, with bar height proportional to rank. The shape shows whether a ticker is consistent across timeframes or, say, "strong in 1Y but middling in 5Y".

Hover the visual summary and a tooltip lists the ticker's average rank plus every period's value and rank. You see all the underlying numbers without losing the visual. Useful when two tickers have similar bar shapes and you want to know exactly where they differ.

Sort the rankings table by any individual period (for example, 5Y return) or by the average rank across all selected periods. The average-rank sort surfaces tickers that perform well across many windows, not just one. The arrow on the column header shows the current sort direction.

Trend Score grades the quality of a price path on a scale from -1 to +1, magnitude-aware and time-normalized so longer windows do not dominate. A score near +1 indicates a smooth, sustained climb; near -1 indicates a smooth, sustained decline; near zero indicates choppy or sideways action. Use it to distinguish tickers that climbed steadily from tickers whose gains came in a few sharp jumps.

Hover the Trend Score column to see the score broken into 12 sub-intervals, each with its own date range, return, and contribution percent to the total. The breakdown shows which segments built the score and which subtracted from it. The metric is inspectable instead of opaque.

Trend Return is a composite that combines raw return with Trend Score, weighting gains earned via a steady path higher than gains earned from a single sharp move. Sort by Trend Return when you want returns weighted by path quality. The resulting order often differs from a sort by raw return.

On the free tier, the multiselect for Quant Metrics still shows every Pro metric (Sharpe, max drawdown, SPY correlation, and others) with a short description and an upgrade nudge. You can see the full menu before deciding to upgrade. The selected metrics make it onto the table immediately after upgrade, no resetting required.

Click the small help icon on any metric column header for a plain-English explanation, the relevant tradeoffs, and a use-case example. No prior finance background required to understand what Sharpe ratio rewards or where Trend Score might mislead. A way to learn the vocabulary of quantitative comparison alongside real work.

The timeframe bar offers more than 20 presets, from 1D, 2D, 3D, and 1W on the short end through 25Y and 30Y on the long end. Click any one and the chart, table, and rankings recompute instantly. A custom date range picker is also available if no preset fits.

For 1D, 2D, and 3D presets, the chart switches to 15-minute interval data with intraday-aware behavior (no whitespace for non-market hours, day-start markers, the latest live quote always included). Useful for fast-moving days when daily granularity is too coarse. Holiday and weekend gaps are handled cleanly so the chart reads naturally.

A dropdown organizes 17 historical events into two tiers. Tier 1 is the canonical episodes (Dot-com Boom and Bust, GFC, COVID Crash and Recovery, 2022 Bear Market, AI Boom, and others). Tier 2 is the deeper cuts (LTCM, 9/11, Brexit, Q4 2018, Banking Crisis 2023, and more). Activate one and the chart snaps to the event's window. Useful for answering "how would my picks have done in the GFC?".

A single session can hold up to 25 comparison sets, each with its own tickers, timeframe, columns, and benchmark. Use them to keep separate workstreams (your IRA, a watchlist, a sector deep-dive, a peer comparison for one stock) without losing context. A quick-switch dropdown lets you flip between sets and your settings travel with each one.

Browse curated collections grouped by category: FEATURED Showcase (the breadth of the app at 25 to 100 tickers), DIVERSIFIED (asset class baskets), SINGLE-ASSET (one slice per category), STOCKS (sector groupings), and SCENARIOS (themes like AI, EVs, banking crisis). Each collection is a one-click way to see a meaningful comparison without typing tickers. Save any of them as your own editable set with the fork button.

When a curated collection is active, a banner above the chart shows the collection's name, emoji, and short description. You always know whether you are looking at "your" set or someone else's curation. Click the fork icon in the banner to copy it into an editable user set.

Every session has a 10-character permalink (e.g., /c/x9k2p3jq8r) you can share with anyone. Open it in a different browser, on a phone, or send it to a colleague, and the recipient sees the exact same comparison. No login required on either side.

You can also share comparisons as readable URLs like /t/AAPL,MSFT,GOOG?preset=1Y. These URLs are typeable, dictation-friendly, and survive without any session storage on the backend, so they work even if you reinstall your browser or share via voice. A purple raw-mode badge above the chart signals when you are in this mode.

Your tier shows as a small icon in the header (a battery-full icon for Pro, a battery icon for Free). It is a quick visual confirmation of which features are unlocked for the current session. Click it to manage your subscription or upgrade.

Every prices fetch shows a small toast with the actual response time ("Results in 84 ms" or "1.23s") so the elapsed time is visible directly, not inferred. The Go backend serves quant metrics in under 100ms for typical comparisons. The toast also confirms that fresh data has arrived.

The control panel groups every setting into two tabs: Essentials (tickers, timeframe, custom range, important period) and Configuration (top performers filter, table metrics, multi-period selector, benchmark). The Essentials tab covers the common day-to-day controls. Configuration holds the deeper tuning for columns, metrics, and benchmarks, without burying the everyday controls underneath them.

Press Cmd+K (or Ctrl+K on Windows/Linux) to open the control panel as a centered modal. Useful when the side panel is collapsed, when you are on a smaller screen, or simply when you prefer keyboard-first workflows. Press Esc to dismiss.
