      <title>Smart Stock Research &amp; Portfolio Tracking Platform India – StockTool.AI</title>

  A small data contract for a portfolio research log
&lt;/h2&gt;

&lt;p&gt;A portfolio research interface has two dates to preserve: when the underlying information was published and when the user reviewed it. Treating those timestamps as interchangeable makes an old filing look like fresh evidence.&lt;/p&gt;

&lt;p&gt;A minimal research record can contain these fields:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;company_id: a stable company identifier&lt;/li&gt;
&lt;li&gt;reporting_period: the period covered by the source&lt;/li&gt;
&lt;li&gt;source_url: a link to the original filing&lt;/li&gt;
&lt;li&gt;source_published_at: the publication date&lt;/li&gt;
&lt;li&gt;reviewed_at: the review date&lt;/li&gt;
&lt;li&gt;claim: the statement that needs verification&lt;/li&gt;
&lt;li&gt;interpretation: the reviewer assessment&lt;/li&gt;
&lt;li&gt;open_question: the uncertainty still to resolve&lt;/li&gt;
&lt;li&gt;status: needs_verification or reviewed&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;This is a proposed data structure, not a description of any platform implementation.&lt;/p&gt;

&lt;h3&gt;
  
  
  Keep evidence and interpretation separate
&lt;/h3&gt;

&lt;p&gt;Store the quoted claim separately from the reviewer interpretation. An AI-generated paragraph should not silently become the source of record. Preserve enough location information for a reader to find the statement in the filing.&lt;/p&gt;

&lt;h3&gt;
  
  
  Append revisions instead of replacing history
&lt;/h3&gt;

&lt;p&gt;When a new filing arrives, create a new review entry. Keep the earlier interpretation and record the reason for the change. This preserves what information was available at each review.&lt;/p&gt;

&lt;h3&gt;
  
  
  Make missing inputs explicit
&lt;/h3&gt;

&lt;p&gt;A blank source date should display as missing, rather than inheriting the review date. An unavailable filing should leave a claim pending verification.&lt;/p&gt;

&lt;h3&gt;
  
  
  Test evidence navigation
&lt;/h3&gt;

&lt;p&gt;Ask a reviewer to open a claim, find the source and identify the reporting period. If these steps are difficult, improve the evidence navigation before adding another summary widget.&lt;/p&gt;

&lt;p&gt;For readers exploring research tools for India, visit &lt;a href="https://stocktool.ai/" rel="noopener noreferrer"&gt;StockTool.AI&lt;/a&gt;. This article accompanies that project; the design above is a general suggestion and does not assert that a particular feature is available.&lt;/p&gt;
