Read every filing. Miss no signal.
SignalFiling watches SEC EDGAR for the companies you follow, turns each 10-K, 10-Q and 8-K into a plain-language summary, and records the forensic signals that matter, with the passage that triggered each one.
Testers receive the iOS app through TestFlight. The web app and the API open at launch. Not yet available on the App Store.
“On September 15, 2026, the Audit Committee dismissed [FIRM] as the Company’s independent registered public accounting firm… the report contained an explanatory paragraph regarding substantial doubt…”
A filing feed, a reader that never skims, and a ledger you can query.
Filing feed
Every new filing for your watchlist, pulled from EDGAR within hours of acceptance. 10-K, 10-Q, 8-K, 20-F and more, resolved to the primary document.
LLM analysis
Each filing is cleaned, read in full and summarised. Signals are detected against a fixed taxonomy and rubric, so results are comparable across companies and years.
Signal ledger + search
Signals live in a ledger with dedup and supersession per company and category. Search the corpus in plain English, or ask a question and get an answer with citations.
From acceptance on EDGAR to a signal in your feed, without a human reading in between.
Ingest
EDGAR submissions are polled for every company on your watchlist. New accession numbers are queued within hours.
Extract
The primary document is resolved by form type and converted to clean text, iXBRL aware, exhibits included where they matter.
Analyse
A model writes the summary and records each signal with category, severity and the evidence passage.
Alert
New signals reach you in the app, a daily digest, or a signed webhook to your own systems.
Specific categories, one fixed rubric.
Every signal carries a category from this list, a severity and the passage that triggered it. Nothing is inferred from price or sentiment; it comes from the filing text.
Going-concern language
Substantial-doubt paragraphs and management plans to address them.
Restatements
Non-reliance notices, restated periods and the accounts affected.
Auditor changes
Dismissals, resignations and any disagreements or reportable events.
Related-party transactions
New or expanded dealings with insiders and affiliates.
Executive departures
CEO, CFO, CAO and director exits, with or without a stated reason.
Covenant breaches
Defaults, waivers and amendments to debt agreements.
Impairment
Goodwill and asset write-downs and the triggering events behind them.
Litigation
Material proceedings, investigations and regulatory actions.
Insider activity
Unusual 10b5-1 changes and clustered transactions.
Liquidity stress
Cash, credit and working-capital language that precedes going-concern doubt.
The same signals, as an API and a webhook.
API access opens with the public launch. Beta testers who need it earlier can ask in the access request.
- REST API over the whole corpus: companies, filings, summaries, signals.
- API keys per integration, with per-minute and per-day quotas you can see.
- Webhooks for
signal.created, HMAC-signed so you can verify every delivery. - Natural-language search and question answering with citations, from the same endpoints the app uses.
$ curl https://api.signalfiling.com/v1/signals?ticker=ACME \ -H "Authorization: Bearer $SIGNALFILING_API_KEY" # webhook: signal.created { "event": "signal.created", "signal": { "ticker": "ACME", "form": "8-K", "category": "auditor_change", "severity": "high", "evidence": "Item 4.01, paragraph 2" }, "signature": "sha256=…" }
