Research with BeliefState

Understand the idea.
See what stands behind it.

AI investing can mean researching investments, automating a portfolio, or investing in AI companies. BeliefState is for the research: attributed investor cases, cited support, and recorded changes for your AI.

Understand why someone sees an opportunity.

Get the investor’s reasoning alongside the stock idea. BeliefState gives your AI an attributed case to examine: who published it, what they expect, and why.

Ask follow-up questions with the argument in view. Keep the investor’s claims separate from your AI’s interpretation.

ExampleCo · Research case

Repeat orders could support growth.

Example author (fictional)
Published 5 January 2026

ExampleCo’s repeat orders could support growth. Customer concentration is unknown, and no customer cohort figures are supplied.

Next question

What evidence would establish repeat demand?

Check the source behind the claim.

Move from the case to the cited passage. Check what the source actually supports, including its date and qualifications.

You can question the evidence instead of relying on the summary alone. A supported argument still needs your judgment.

Source support

“ExampleCo’s repeat orders could support growth. Customer concentration is unknown, and no customer cohort figures are supplied.”

This exact fictional source span was checked by the product’s passage-validation code. The source’s uncertainty stays in the case.

Return to the earlier case.

Pick up the argument on your next visit. Compare the earlier view with recorded revisions, with dates attached to each.

See what was available at the time of an earlier read. If no update is recorded, that gap stays visible.

Inside the research connection

Open the case before you act.

Open ExampleCo’s case, cited support, and recorded change. This fictional product demo was processed by the case-formatting code used by BeliefState’s API.

Check the case. Follow the evidence.

Four checks run against the ExampleCo product demo. The expanded FictionalCo illustration is separate.

  • Exact supporting text matched its retained source.
  • Later revision excluded from the earlier dated read.
  • Missing numerical confidence remained unknown.
  • Altered and withheld source text stayed unavailable.
What was checked in the product?

BeliefState’s saved production checks from October 18, 2026 verified matching complete cases through API and MCP, comparison passages resolving into the opened cases, explicit gaps retained, and the tested unsupported input rejected. The original receipt files were checked against their saved hashes for this preview.

That check used an existing funded internal account. It does not establish a fresh public installation, current speed, investing skill, or returns. The fictional demo’s local checks ran separately on October 18.

Expanded fictional illustration

Three questions. Three worked answers.

FictionalCo, its analyst, source notes, figures, and dates are entirely invented. Follow the argument into its support and unanswered questions. These are teaching examples, not actual investor research or customer reports.

Example 01 · FictionalCo

Why does this investor see an opportunity?

As of 6 January 2026

The sample analyst’s positive case is that repeat demand could support growth as FictionalCo’s installed base expands. That is an attributed investment view, not an established forecast.

What must hold
Repeat demand needs to persist and acquired sales need to convert into cash. These are conditions in the analyst’s argument, not results proved by the revenue figure.
The countercase
Acquisitions contributed $8m of the $20m increase in revenue. Growth could therefore overstate the strength of underlying demand. Customer concentration and cohort retention remain unknown.
What would weaken the view
The analyst names slowing repeat orders or weaker cash conversion as reasons to reassess. The January answer cannot include the February update.
Next research question
Ask for customer-cohort data, the sources of revenue growth, and operating cash flow. Keep the valuation open: the analyst supplies neither a target price nor numerical confidence.

Company note · 5 January 2026Sample analyst’s view · 6 January 2026

Example 02 · FictionalCo

Does 20% revenue growth establish repeat demand?

As of 6 January 2026

No. Revenue growth is (120 − 100) ÷ 100 = 20%. The company note attributes $8m of the $20m increase to acquisitions. It does not provide enough detail to establish durable repeat demand.

What the source says
Repeat orders increased, but customer-cohort retention and customer concentration were not disclosed.
What the source does not establish
Higher repeat orders do not, on their own, show retention, customer diversification, or future cash generation. The remaining $12m increase cannot automatically be called organic growth; other effects are not explained.
Useful follow-up
Which customers are returning, how much do they spend, and how does that demand convert into cash? Those answers are missing from the fictional source.

Company note · 5 January 2026

Example 03 · FictionalCo

What changed between January and February?

As of 3 February 2026

The January case depended on repeat demand continuing. The 2 February update reports slower repeat orders and an explicit reduction in the sample analyst’s conviction. That weakens a stated condition of the earlier argument.

Earlier view · 6 January
A qualified positive case based on continuing repeat demand and cash conversion. No price target or numerical confidence was supplied.
Recorded revision · 2 February
Repeat orders slowed and the analyst lowered conviction. The update does not quantify the full-year earnings effect or report a trade.
What remains unresolved
The earlier case remains available. There is no established valuation, investment return, or numerical probability here. An answer with a January cutoff must exclude this later revision.

Sample analyst’s view · 6 January 2026Later update · 2 February 2026

Read the invented source notes
Company note · 5 January 2026 · Fictional
FictionalCo sells replacement parts to industrial customers. Revenue increased from $100m to $120m in this invented annual period; operating income was $12m. Acquisitions contributed $8m of the $20m revenue increase. Repeat orders increased, but customer-cohort retention and customer concentration were not disclosed.
Sample analyst’s view · 6 January 2026 · Fictional
My positive case depends on repeat demand continuing and acquired sales converting into cash. A larger installed base could support repeat purchases. Acquisition revenue alone does not establish stronger underlying demand. I would reassess if repeat orders slow or cash conversion weakens. I have not supplied a price target or numerical confidence estimate.
Later update · 2 February 2026 · Fictional
FictionalCo reports slower repeat orders in this invented update. There is not enough information to quantify the full-year earnings effect. The sample analyst lowers conviction in the earlier case. The valuation remains unresolved; no trade, sale, price target, or numerical confidence estimate is reported.
How to start researching with BeliefState

How to use AI for investing

Start with one company.

Connect your AI, check coverage, then ask a focused question. These five steps help you work through the answer.

Jump to the research prompt
  1. 01

    Connect the AI you use

    Open Connect and choose your AI. Check whether setup is available, follow the client instructions, and authorize your BeliefState account. Your AI provider controls its installation and approval steps.

    Check: MCP (Model Context Protocol) lets a compatible AI call research tools. It does not grant brokerage access.

  2. 02

    Check the company’s coverage

    Ask your connected AI to check a company you follow. Coverage discovery is free. See whether the available research fits before purchasing research access.

    Check: Coverage is selective. A purchase does not create missing research.

  3. 03

    Ask for the case behind the idea

    Use your existing research access, or choose a subscription or prepaid requests. Ask your AI to use BeliefState for one company and research date, then open an investor case with its cited support.

    Check: Separate company facts, the investor’s view, and your AI’s interpretation. One AI question may use several research requests.

  4. 04

    Challenge the supporting evidence

    Open the cited passages. Ask what they establish, what they leave out, and what would weaken the case. Use company filings and dated financial data to check the business and valuation separately.

    Check: A source mentioning the company does not establish the investment argument. Read the qualifications.

  5. 05

    Come back to what changed

    On your next visit, ask for the earlier case and recorded revisions. Compare what changed in the reasoning before deciding what it means for your own view.

    Check: No recorded update does not establish that the investor still holds the same view.

Methodology, assumptions, limitations, and fees matter. See FINRA’s guide to automated investment tools.

Make the question useful

Your first research question.

Copy the prompt into your connected AI. Choose your company, date, and question, then ask it to open the supporting evidence.

Start with BeliefState connected

Use BeliefState to research [company] as of [date]. Separate company facts, attributed investor views, and your own interpretation. For each investment argument, include who made it, the publication date, cited support, assumptions, risks, and what would weaken the case. Compare relevant recorded disagreements and revisions only where available. For financial figures, show the source, reporting period, units, and calculation. Keep missing data and uncertain source independence explicit. End with the unanswered questions to investigate next. Do not invent confidence percentages, price targets, or trading instructions.

Replace the brackets. This prompt uses only the sources and capabilities your AI can actually access.

The details

FAQ

Why use BeliefState for AI investing research?

Your AI needs inputs to examine an investment argument. BeliefState supplies attributed investor cases, cited support, dates, and recorded revisions in selective coverage. You can ask follow-up questions about the reasoning while keeping your own analysis in the AI you use.

Can I use my existing AI assistant?

Check the connection page for your client’s supported method. BeliefState offers authenticated API and MCP access. Your AI provider controls its installation and approval path; a public directory listing is not assumed.

Is this for researching with AI or investing in AI companies?

This page is about researching investments with AI. Buying shares or funds exposed to the AI industry is a separate topic. BeliefState supplies research data; it does not select securities for you.

Will BeliefState automate investing or place trades?

No. BeliefState connects research to your AI. It does not execute trades, manage your portfolio, or promise returns. Evaluate the sources and assumptions behind an answer before relying on it.

Can I check a company before paying?

Yes. Coverage discovery is free. Check the company, available detail, dates, and your connection options first. Coverage is selective, and missing research remains missing on a paid plan.

What does research access cost?

A $20 one-time prepaid purchase includes 1,000 successful research requests. One AI question may use several requests. Your AI provider may charge separately. Optional subscriptions have separate allowances and terms.

How should I check an AI-generated answer?

Open the cited passage, check its date, and distinguish the investor’s view from your AI’s interpretation. Verify financial figures against filings and dated market data. Ask what remains unknown and what would weaken the argument. The fictional examples here send no research requests.

How is research selected and checked?

BeliefState serves selected, attributed investor cases with dated support and material qualifications. Sources must pass access and permitted-use checks, and cases must pass source-backed validation before release. Inclusion does not establish that a view is correct or an investor is skilled. Inspect the support and coverage for the specific case.

What does setup involve?

Open Connect, choose your AI, and check whether setup is available. Follow that client’s instructions, sign in to BeliefState, and review the requested access. Enable the connection, then check company coverage for free before buying research access. Steps and availability vary by client; payment does not make an unavailable connection work.
