# Real-Time SEC Filings Feed for All Public Companies

> Insighthread streams every SEC filing from EDGAR in real time, covering all 6,000+ US public companies with instant AI analysis on any document.

Insighthread gives you a live feed of every SEC filing the moment it appears on EDGAR — for all 6,000+ US public companies. There is no delay, no editorial filter, and no third-party intermediary between the source document and your screen. Whether a company just filed a routine 10-Q or a market-moving 8-K, you see it within 60 seconds and can immediately ask the AI to analyze it. This is the primary source for everything in Insighthread: the news feed, the event signals, the insider trade data, and the AI Chat answers all trace back to filings you can access directly here.

## Filing Types Covered

Insighthread covers the full range of filing types that matter most to equity investors:

| Filing Type  | Description                                                                                                                                                                |
| ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| **Form 4/A** | Amended insider transaction report — corrects or supplements a previously filed Form 4                                                                                     |
| **Form 144** | Notice of proposed sale of restricted securities — filed when an affiliate intends to sell restricted or control securities under Rule 144                                 |
| **15-12B**   | Certification of termination of registration — filed when a company deregisters a class of securities, effectively going dark                                              |

## Reading a Filing

<Steps>
  <Step title="Find a Filing in the Filings Feed">
    Open the **Filings** tab for any company at [app.insighthread.com](https://app.insighthread.com) to see a reverse-chronological list of all recent SEC submissions. Use the filing type filter to narrow the list to specific form types — for example, filter to **8-K** only to see all current report disclosures.
  </Step>

  <Step title="Click to Open the Source Document">
    Click any filing entry to open the raw SEC document. Insighthread displays the filing as submitted to EDGAR, with no modifications to the text or structure. Exhibits and attachments are included where the SEC accepted them as part of the submission.
  </Step>

  <Step title="Click Ask AI for Instant Analysis">
    Select **Ask AI** from within the filing view to open AI Chat pre-loaded with that document as context. Ask the AI to summarize the filing, extract specific figures, identify key changes, or explain regulatory language — all without leaving the page.
  </Step>
</Steps>

## Primary vs. Secondary Filings

Not every filing is a fresh disclosure — some filings correct, amend, or supplement earlier submissions. Insighthread distinguishes between the two:

<Tabs>
  <Tab title="Primary Filings">
    A **primary filing** is the original submission. This is the document a company files to make an initial disclosure — for example, the original 10-K for a fiscal year or the original Form 4 reporting an insider transaction. Primary filings are the authoritative record of the event as first reported.
  </Tab>

  <Tab title="Secondary (Amended) Filings">
    A **secondary filing** amends or supplements a primary filing. Common examples include a **Form 4/A** that corrects an error in a previously reported insider transaction, or an **8-K/A** that updates disclosures from an earlier 8-K. Insighthread tracks both the original and the amendment so you always have the complete picture — and flags when an amendment materially changes what was originally disclosed.
  </Tab>
</Tabs>

When reviewing insider trade data or event history, check whether an amendment has been filed — a Form 4/A that reduces a reported purchase can significantly change the signal.

<Tip>
  Use AI Chat to work through a lengthy 10-K without reading every page. Ask it to summarize the MD\&A section, pull the revenue and operating income figures, list the top risk factors, and flag any going-concern language — all in a few minutes instead of a few hours.
