Edgar's Spear Review: SEC EDGAR Single-Quarter Filing Analysis (2026)

Opening

Open a 10-Q on SEC EDGAR and try to chart this quarter’s revenue against the prior quarter. Many income-statement tags arrive as year-to-date cumulatives—Q2 is often first-half total, Q3 is nine months—so a naive chart plots apples against oranges. Spreadsheet users subtract by hand. Terminals charge for cleanup. Most free quote sites never say how they got to a “quarter.”

Edgar's Spear is built for that gap. It pulls recent 10-Q / 10-K filings from EDGAR, converts raw XBRL into charts and snapshots, and derives true single-quarter revenue and income by subtracting those cumulative figures. Paid tiers add CFA-style ratio cards, peer comparison, CSV/JSON export, and AI summaries glued to the math already on screen.

Key takeaways

• The wedge is honest single-quarter P&L from EDGAR XBRL. Quarters are derived by subtracting cumulative YTD values (Q2 = H1 − Q1, Q3 = 9-month − H1, Q4 = FY − 9-month) and marked directional, with the linked filing as authority.
• Free ($0): search, revenue / income / EPS by quarter, balance-sheet snapshot, filing links, watchlist. Plus ($10/mo): 12 core CFA Level I–style ratios + AI summaries. Pro ($25/mo): 13 advanced ratios (DuPont ROE, cash conversion cycle, EBITDA margin, interest coverage, turnover, peer benchmark), CSV/JSON export, first access to new formulas—per Plans panel and /api/plans (September 2026).
• “Does it balance?” checks arithmetic identities (assets vs liabilities + equity, plus composition / income / rollforward)—not a qualitative judgment on the business.
• AI ratio summaries (Plus/Pro) use only selected card labels, formulas, and values. Vendor: model is not told the company name and should not invent outside facts. Labeled not financial advice.
• Promo: first 50 signups get Pro free via [email protected]. Counter during research: 49 of 50 left.
• Strong for students and indie fundamentals. Watchlist mail covers a new 10-Q or 10-K; still the wrong seat for options, private companies, or multi-seat terminals.

What is Edgar's Spear?

A browser app for U.S. public-company filing analysis. Search a ticker or name; it fetches recent EDGAR filings and renders single-quarter revenue and net income (QoQ / YoY framing), diluted EPS where tags exist, a balance-sheet snapshot, recent filings with sec.gov links, paid ratio grids, and optional AI over selected ratio cards.

EDGAR is the SEC’s Electronic Data Gathering, Analysis, and Retrieval system; Spear is the claim to get past the filing surface to usable numbers. Official branding: Edgar's Spear (apostrophe); domain edgarspear.com.

Not a brokerage, news feed, mega-screener, or MD&A replacement—a filing-first fundamentals viewer that publishes how quarters are made.

Evaluation methodology

Reviewed: homepage, About, Blog (balance-check / Interest Coverage / promo / AI posts), /api/plans and /api/promo/free50pro, unauthenticated /api/company/320193, and the Launchpadly listing (slug via search q=edgar).

We did not run a paid Plus/Pro month, re-audit every XBRL mapping, or score AI text against sell-side memos. Competitor notes are positioning (Yahoo Finance, Finviz, Seeking Alpha, Koyfin, Calcbench-class XBRL, Bloomberg/FactSet)—not vendors named on Spear’s site.

Product overview

Workflow

1. Search ticker or name (examples: AAPL, Apple).
2. App pulls filings from EDGAR.
3. Read quarter charts, balance sheet, filing links.
4. Skim Does it balance? and any “derived” notes.
5. On Plus/Pro: ratio cards → optional select → Summarize; on Pro: CSV/JSON and peer benchmark.
6. Watchlist—emails you when a new 10-Q or 10-K posts. The tab does not have to stay open.

Signup, password reset, email verification, Stripe Checkout. About keeps prices only on the Plans panel.

What Free returns

API: tier = free, hasRatios = false, ratios = null. Metrics still rich—Apple showed multi-year revenue with cumulativeVal and quarterVal, plus income, EPS, balance lines, interest, inventory, AR/AP, D&A, retained earnings, dividends, shares when tags resolve. ~12 recent 10-Q/10-K links. Free is a real quarter viewer; ratios/export are the paywall.

Product honesty

Derived quarters are standard but not filer-reported audited discrete quarters—always open the link. Blog: Oracle’s blank balance check fixed by deriving liabilities (liabilities-and-equity − equity) with a label; Interest Coverage dual-checks old/new interest-expense tags after 2024 splits and still dashes banks where the ratio is not meaningful.

Some large filers—FedEx, Oracle, and Amazon among them—do not tag a standalone Liabilities total in SEC XBRL. That used to blank Debt/Equity and Debt/Assets even when the rest of the filing was enough to derive those ratios. That derivation is in place. A remaining — means the filer’s own SEC filing does not report that line item; Spear is not skipping a number it has. An on-page note says so.

The footer and the About page now carry a not financial advice disclaimer.

Key features

Single-quarter P&L

Headline job: subtract YTD cumulatives so charts show discrete quarters. Can replace a fragile spreadsheet—if you verify restatements, stubs, and tag changes against the filing. The subtraction rule is the same one About documents: Q2 from first-half minus Q1, Q3 from nine-month minus first half, Q4 from full-year minus nine-month. That math is simple; the hard part is trusting the XBRL tags underneath, which is why every chart sits next to a filing link.

EPS, metrics, balance sheet

Free lists revenue, income & EPS by quarter. Metrics feed charts and paid ratios. Balance block: latest assets, liabilities, equity, cash, related lines.

Does it balance?

Arithmetic identities with badges/variance. Composition and RE rollforward can fail while primary assets = liabilities + equity holds (seen on Apple’s public payload). Treat as filing-structure diagnostics, not fraud headlines.

Plus ratios

12 cards: margins; liquidity (current / quick / cash); working capital; debt and capital-structure ratios; ROA / ROE; book value per share; more formulas planned. Values + formulas on cards.

Pro ratios, peers, export

13 advanced: DuPont ROE, full cash conversion cycle, EBITDA margin, interest coverage, turnover, more; peer tickers; CSV/JSON; first access to new formulas. Banks may correctly dash Interest Coverage.

AI summaries

Plus/Pro: select cards or summarize all → one paragraph from on-screen math only. Not a thesis engine—and that is the point.

Watchlist

Emails watchlisted users when a new 10-Q or 10-K posts. Checks run as often as every 15 minutes on weekdays during SEC active filing hours (6am–8pm ET), and less often outside that window. You do not need the app open. That notice is email, not a mobile push notification, and it does not cover other form types.

Pricing and value

As of September 2026 research (/api/plans + Plans panel). Confirm in-app.

Plan	Price	Notable unlocks
Free	$0	Search; revenue, income & EPS by quarter; balance snapshot; filings; watchlist
Plus	$10 / month	+ 12 core ratios; AI summaries; more formulas planned

Free alone is enough if YTD-vs-quarter is your pain. Plus at $10 and Pro at $25 undercut terminal seats for personal CFA-style work—you are not buying news wires, consensus estimates, or a compliance packet. No public annual discount table or team/SSO/SLA language on pages reviewed. Ratio catalogs and XBRL coverage will keep changing, so treat today’s feature list as a snapshot and re-check Plans before renewing.

UX (8): One workspace, clear gating, dark mode, filing links; blanks/variances need literacy. Value (9): Free ships the wedge; $10/$25 is honest vs terminals. AI (7): Trustworthy narrow scope, low ceiling. Automation (7): Pro export, plus email when a watchlisted 10-Q or 10-K posts—not mobile push, and not other forms. Depth (7): Strong focus, not a full research platform yet.

Pros and cons

Pros

• Publishes the YTD→single-quarter method in plain language
• Free tier is genuinely useful before payment
• Simple Stripe pricing ($10 / $25) confirmed on /api/plans
• Ratio cards show formulas, not only percentages
• Balance checks and derived-liability notes surface filer quirks
• Restrained AI with explicit non-advice labeling
• Footer and About page state that this is not financial advice
• Pro CSV/JSON + peer tickers fit notebook workflows
• Support email + public blog of concrete XBRL fixes

Cons

• A remaining — means the filer’s SEC filing omits that line (noted on the page), not a calculation Spear skipped
• AI will not research the company
• No public team/SSO tier
• U.S. EDGAR public filers only
• Thin community proof on Launchpadly at listing time

Real use cases

CFA study. Free charts + Plus ratio cards against live 10-Qs; bank Interest Coverage dashes become a teaching moment.

Indie writeup. Pro JSON export + peer benchmark + sec.gov footnotes; AI only as a draft on liquidity cards, then rewritten from the filing.

Pre-meeting diligence. Free QoQ revenue, balance snapshot, and primary identity check the morning of a call; Plus if ratios beat rebuilding a sheet under time pressure.

Verdict

Edgar's Spear is a focused EDGAR workstation for people who care how quarterly numbers are made. Free already ships single-quarter series, filing links, and identity checks. Plus and Pro add CFA-style depth, restrained AI, peers, and export at personal-seat prices.

Buy if you reconcile EDGAR cumulatives by hand, study fundamental ratios, or want a $10–$25/mo seat that stays honest about derived data and non-advice AI.

Skip if you need trading tools, a news wire, estimates consensus, multi-user compliance, or AI that invents a bull/bear story. Watchlist mail will not stand in for those.

Start on Free with two tickers you know cold. If the quarter series match your manual math and the balance panel teaches you something about the filing, Plus is the default upgrade; take Pro when you need DuPont/CCC-class cards, peers, or CSV/JSON. If a promo Pro seat remains, email support after signup and skip the card until you outgrow the gift.

FAQ

What is Edgar's Spear best for?

Turning SEC EDGAR 10-Q / 10-K XBRL into true single-quarter charts, balance snapshots, filing links, and (paid) CFA-style ratios with optional AI narration of those ratios.

How much does it cost?

September 2026 research: Free $0, Plus $10/month, Pro $25/month (USD). Confirm in-app—About does not hard-code prices.

Is Free actually useful?

Yes: search, quarterly revenue/income/EPS, balance snapshot, watchlist (email when a new 10-Q or 10-K posts), sec.gov links. Ratios, AI, peers, and export are Plus/Pro.

Are quarters audited statements?

No—they are derived from cumulative YTD XBRL and labeled directional. Always verify the linked filing.

What does the AI summary do?

Plus/Pro only: one paragraph from selected (or all) ratio labels/formulas/values. Not financial advice; not company research from model memory.

How do I claim free Pro?

Sign up, email [email protected] from that address while first-50 promo spots last. Live counter shows remaining seats.

How does it compare to Yahoo or Bloomberg?

Yahoo-class tools win on quotes/news/screeners. Bloomberg/FactSet win on institutional breadth. Edgar's Spear wins on a cheap, transparent EDGAR quarter and ratio lens. A dash still means that line is absent from the filing.
