Short answer — it varies a lot by product and plan, but expect one of these ranges in India today:

• Free / broker‑integrated: many broker platforms and “AI” features are free or bundled with brokerage (e.g., Smallcase via brokers, Zerodha basic tools). (investorai.Smallcase.com)
• Low‑cost retail plans: roughly ₹150–₹500 per month for consumer/retail AI tools or “pro” tiers (examples: Tickertape/other stock‑screening pro tiers around ₹249; STOCKSherpa ₹201/month). (OneDemat.com)
• Mid‑tier trader plans: roughly ₹1,000–₹5,000 per month for more frequent signals, backtests, model portfolios or intraday/quant tools. (many platforms offer monthly “trader/pro” tiers). (parikshitkhanna.com)
• Enterprise / institutional levels: ₹10,000–₹50,000+ per month (or custom/annual contracts) for real‑time, near‑real‑time data, dedicated models, or white‑label/firm licences. (parikshitkhanna.com)

Representative examples (prices shown on vendor sites or industry listings):

• STOCKSherpa — trial + paid plans: ₹201/month or ₹501/year (example consumer AI screener). (STOCKSherpa.in)
• Tickertape / similar screens — free tier + Pro ≈ ₹249/month (example of low‑cost screening + AI insights). (OneDemat.com)
• Trade/quant platforms and trading‑tool bundles — pro plans in the mid‑thousands per month (varies by vendor). (parikshitkhanna.com)
• Smallcase / InvestorAI — many portfolios and AI‑curated smallcases are available through brokers; pricing/execution costs are usually brokerage + any Smallcase subscription or fee structure. (often effectively free to view; execution costs via broker). (investorai.Smallcase.com)

Notes and practical tips:

• “AI stock recommendation” is a broad label — some products are simple scoring/screeners, others sell model portfolios, real‑time signals, or automated execution. Higher frequency/real‑time services cost more. (OneDemat.com)
• Many providers change plans, run promotions, or have annual discounts — check the vendor page for the latest pricing or ask for a trial. If you want, I can look up current prices for specific services (name 3–5 vendors you care about) and return exact current plans and links. (STOCKSherpa.in)

If you want, tell me 3 services you’re considering (or the type of use — long‑term portfolios, intraday signals, model backtests) and I’ll fetch up‑to‑date prices and compare plans.
