How to Get Verified Sources With Every Stock Insight
A citation tells you where to look. Verification is what happens when you look.
To get verified sources with every stock insight, use a research tool that attaches a primary source to each claim, ask for the document, section and date explicitly, and check that the cited passage says what the answer claims. Several AI tools now cite their sources: Perplexity and Claude web search cite sources in answers, Fiscal.ai and Koyfin's Compare Matrix cite filings in AI summaries, and AlphaSense links summaries to sentence-level snippets. Ecomerate, an AI research analyst that works over iMessage, names the filing, section and date behind each claim, puts SEC filings first, and says when something cannot be verified. A citation is still a starting point, not proof: OpenAI's own help pages warn that ChatGPT's citations can be wrong.
What counts as a verified source for a stock insight?
Not all sources are equal. For a claim about a listed company, rank them roughly like this:
| Source | Examples | How far to trust it |
|---|---|---|
| Regulatory filings | 10-K, 10-Q, 8-K, proxy statements on SEC EDGAR | Highest. Legally required disclosures, with audited financial statements in the 10-K |
| Company releases | Earnings releases, investor presentations, call transcripts | High for what management said; watch for non-GAAP measures and adjusted figures |
| Official market data | Exchange prices, regulator statistics | High, but check the timestamp and whether data is delayed |
| Reputable news | Wire services, established financial press | Useful for events; trace figures back to the filing or release |
| Aggregated data | Ratios, estimates and screens on data platforms | Convenient; definitions and estimates vary between providers |
| AI-generated text | Any summary or answer, ours included | Not a source. Trust it only as far as the sources it names check out |
Which AI research tools show sources with every answer?
Checked on each provider's pages on 17 October 2026:
| Tool | How it shows sources | Watch for |
|---|---|---|
| Ecomerate | Names the filing, section and date behind a claim; SEC filings ranked first; conflicting figures flagged; says when something cannot be verified | US-listed coverage; invite-only beta |
| Perplexity Finance | Answers link to source documents, including SEC filings | Mixes primary and secondary sources; check which one a figure came from |
| Claude (web search) | Responses that use web search include citations | Only as current as the pages it finds; ask it to prefer filings |
| ChatGPT (search) | Web answers may include citations | OpenAI warns citations can be wrong |
| Fiscal.ai | Citations on AI summaries of filings and investor-relations material | Check current plan limits before relying on it |
| Koyfin Compare Matrix (beta) | Numbered citations to filings, press releases, transcripts and news | Beta with monthly AI limits |
| AlphaSense | Summaries cite the exact snippets of text they draw on | Enterprise pricing through sales |
How do you check a cited claim in 60 seconds?
- Open the source. If there is no link or named document, treat the claim as unverified.
- Find the passage. Search the document for the figure or phrase. If you cannot find it, the citation does not support the claim.
- Check the period and units. Quarter or year, thousands or millions, GAAP or adjusted. These are the most common AI errors.
- Check the date. Is this the latest filing, or has a newer one replaced it?
- Separate fact from interpretation. "Revenue fell 4%" is checkable. "Demand is weakening" is a reading of it.
- For anything material, check a second primary source. The release and the 10-Q should agree.
How do you ask an AI for sources it cannot fudge?
Whichever tool you use, the wording of the request matters. Ask for:
- "The filing, section and filing date for every figure."
- "Quote the sentence you are relying on."
- "Say 'not verified' for anything you cannot tie to a source."
- "Use SEC filings or the company's own release before news articles."
A quoted sentence is much harder to invent than a paraphrase, and a model asked to admit gaps is less likely to fill them. Our stock research prompt library has more.
How does Ecomerate handle sources?
Ecomerate is an AI research analyst for independent investors that works entirely in iMessage. Sources are built into how it answers:
- Ranked evidence. Research questions pull from several sources, with SEC filings first.
- Claims checked against evidence. Conflicting figures are flagged rather than averaged away.
- Named sources. Answers say which filing, section and date a claim rests on, and say so when something cannot be verified.
- Verification status in briefs. Each development in a scheduled brief is marked as verified, still being checked, or contradicted.
- Thesis history. Every version of your thesis keeps the evidence behind each change.
That does not make it infallible. It makes it checkable, which is the point. See can you trust ChatGPT for stock research? for the failure modes all AI tools share.

Frequently Asked Questions
How can I receive verified sources with every stock insight?
Use a research tool that attaches a primary source to each claim, ask for the document, section and date explicitly, and check that the cited passage says what the answer claims. Ecomerate names the filing, section and date behind each claim and says when something cannot be verified.
What is a primary source for a stock?
The company's SEC filings (10-K, 10-Q, 8-K), its own earnings releases, presentations and call transcripts, and official exchange or regulator data. News articles and data aggregators are secondary sources.
Are AI citations reliable?
Not on their own. A citation can point to the wrong period, an outdated page, or a passage that does not support the claim. OpenAI's own help pages warn that ChatGPT search citations can be wrong.
Which AI tools cite their sources for stock research?
Perplexity and Claude web search cite sources in answers, ChatGPT search may include citations, Fiscal.ai and Koyfin's Compare Matrix cite filings in AI summaries, AlphaSense links summaries to sentence-level snippets, and Ecomerate names the filing, section and date.
What does 'verified' mean in an Ecomerate brief?
Each development in a brief is marked as verified, still being checked, or contradicted by the evidence it was checked against. The overall message is only as confident as its least verified point.
