Indian investors have several good stock research websites to choose from. Four that are often compared are PositoAI, Screener.in, Trendlyne and Tickertape. They overlap, but each is built around a different idea. This guide sets out what each one offers, based on their public pages as of October 2026, so you can decide which fits each task. Features and plans change, so check each site for the latest details.
PositoAI
PositoAI is built around a single proprietary score and a warning system.
- Positivity Score and Positivity Index: every tracked company gets one score, calculated by a highly complex proprietary algorithm using a large number of parameters, and a daily rank globally and within its country.
- PosiFlag: two levels of warning, red flags (PosiRed) for regulatory actions, insolvency and delistings, and yellow flags (PosiYellow) for stress signals such as promoter pledges.
- Index view: Senty ranks the Sensex and Nifty 50 companies by score.
- Other tools: ready-made Explore lists, a custom Screen, Go Deep financials, AI-written company summaries, bulk and block deals, corporate actions and a Watchlist.
- Access: every feature is free, with no premium plan and no sign-up.
- Limits: PositoAI is new. Its financial history is shorter than long-established sites, and it has only basic charts.
Screener.in
Screener.in is known for fundamental data and custom screening.
- More than 10 years of financial data for listed companies.
- Custom stock screens written as queries.
- Export to Excel.
- An automatic pros and cons checklist on company pages.
- A free plan and a paid Premium plan.
Trendlyne
Trendlyne offers a wide set of research tools around its own scores.
- DVM scores (Durability, Valuation, Momentum) for stocks.
- Screeners, portfolio reports and a dashboard of stocks under exchange surveillance (ASM and GSM).
- Alerts, backtesting and forecasts on paid plans.
- Free features plus several paid subscriptions.
Tickertape
Tickertape focuses on a clean layout and scorecards.
- A stock Scorecard with performance, valuation, growth and profitability scores; these four scores need a Pro membership.
- A red flags section in the Scorecard, covering items such as promoter pledged holdings and exchange surveillance lists.
- Coverage of mutual funds and other products alongside stocks.
- A free plan and a paid Pro plan.

- Long financial history: strongest on Screener.in (10+ years).
- Paid plans: Screener.in, Trendlyne and Tickertape offer paid plans; PositoAI has none.
- Account needed: PositoAI needs no sign-up for any feature.
Which to use when
- For a quick overall view and warning signs: PositoAI's score, Senty and PosiFlag, free and without an account.
- For deep, long-term financial study and custom queries: Screener.in.
