About Litmus Paper

Indian business and market news, clustered into stories and tested for tone.

Litmus Paper is a free news reader for people who follow Indian stocks. Every 20 minutes it reads 68 news feeds from 25 newsrooms and regulators, from the Economic Times, Moneycontrol, Mint and Business Standard to the RBI, plus Google News, which brings in over a hundred publishers a week. It turns them into one page of stories: what the press is covering right now, how it reads for the market, and what moved.

How a story is made

  1. Clustered. Reports about the same event are grouped into one story, so a result covered by fifteen outlets shows up once, with all fifteen links.
  2. Ranked by coverage. Stories are ordered by how many publishers carry them and how much they matter for Indian markets, and fade as they age. The top of the page is what most of the business press is writing about.
  3. Summed up in three bullets. A language model writes one to three short, factual bullets from the reports’ own text, with the key words in bold, and a line on why it matters for Indian stocks, or none rather than filler. A story known only by its headline gets tags but no bullets until a report with text arrives.
  4. Tested for tone. Each story is marked bullish, bearish or mixed for the stocks it names (or Indian equities as a whole), given an event label (Results, Deal, IPO, Order win, Expansion, Funding and debt, Leadership, Broker call, Legal, Policy, Data, Market move) and tagged with the companies, people, places, organisations and topics in it.
  5. Checked against the market. For NSE-listed companies, the tag shows how the share has moved since the story broke, next to the Nifty.

Market pulse

Market pulse is the board of every tag with two or more stories in the last 24 hours, coloured by net tone: bullish minus bearish articles, as a share of all of them. Sector tags show their NSE index alongside, with a flag where the market disagrees with the news. The front page opens with its busiest four rows.

What it is not

Not investment advice, and not a substitute for the reports themselves. The bullets are machine-written and can be wrong or miss context; every story links to the original reports, so read them before acting on anything. Headlines, images and snippets belong to their publishers.
