Product guide

Build a thesis that gets smarter with every source.

The fastest path from installation to a useful, evidence-backed research workspace.

01

Install and sign in

  1. Install MarketEcho AI from the Chrome Web Store.
  2. Pin the extension so it stays within reach while you browse.
  3. Open it and sign in with email and password or Google.
  4. If you registered with email, verify the address from your inbox before starting research.
The extension uses its own secure sign-in. The website never asks you to pass a login token or extension ID through a URL.

02

Create a project and state the thesis

A project is the durable home for one company, theme, or decision. Give it a clear name, then record the thesis you want the evidence to test.

A useful thesis is specific

Instead of “NVIDIA is a good company,” try “AI infrastructure demand can sustain above-market data-center growth for the next three years despite margin normalization.” This gives each new source something concrete to strengthen, weaken, or leave unresolved.

03

Capture the source already in front of you

  • Web page: open the extension beside the article and choose Capture this page.
  • PDF or filing: capture the document in Chrome, or import a local PDF.
  • YouTube and video: capture the current video or paste its URL.
  • Audio or local material: add the file from the source menu.
  • Notes: paste text when the source is outside the browser.

Before capturing, check the active project and angle. MarketEcho will place the source there and use the current thesis as context.

04

Start with the thesis delta

The Brief view leads with what matters for the decision:

  • Thesis signal summarizes whether the source is strengthening, weakening, mixed, or immaterial.
  • Strengthens shows assumptions that gained support.
  • Weakens exposes evidence against the current view.
  • Unresolved keeps important gaps visible instead of inventing certainty.
  • Open questions suggests what to investigate next.
MarketEcho can propose a thesis change, but your written thesis remains yours until you choose to edit it.

05

Inspect claims and sources

Open Evidence to move between the conclusion and the material behind it. Use claim filters to focus on metrics, catalysts, risks, or unresolved questions. Citation markers such as [S12] and [P4] point back to a source section or PDF page.

AI can still make mistakes. For any decision-critical number or quote, open the cited source and verify it directly.

06

Use angles to separate questions

Angles are focused lines of inquiry inside the same project. Common angles include Core thesis, Valuation, Competitive position, Management quality, and Risks. Use them when two questions need different evidence but still belong to one investment case.

07

Compare before you conclude

Compare sources, angles, or time periods to surface agreements and contradictions. This is especially useful for:

  • Management guidance versus external industry data.
  • The current quarter versus the original thesis baseline.
  • Bull and bear interpretations of the same event.
  • Multiple companies exposed to the same theme.

08

Keep and share the work

Copy a brief for a note, export structured research, or save a project for later. Names, angles, source history, and thesis context make it easy to continue where you stopped.
