Two well-known names that do genuinely different things. Here is which one fits how you actually invest.
The short version. TradingView is the best charting platform available to individuals. Koyfin is a fundamentals and macro dashboard. If you are choosing between them you are really choosing between technical and fundamental analysis.
TradingView exists to draw on price charts. The drawing tools, indicators, custom Pine scripts and social ideas feed are unmatched. Koyfin exists to display fundamentals and macro: financial histories, estimates, yield curves and sector dashboards. Neither is a weaker version of the other.
Koyfin is far stronger. Multi-year financials, analyst estimates, segment detail and comparison tables are the product. TradingView has added fundamental data and it remains a supporting feature attached to a charting tool.
TradingView by a wide margin, and it is not really contested. If your process involves technical setups, custom indicators or backtested strategies, nothing at retail price competes.
TradingView is usable free with paid tiers for more indicators, alerts and data. Koyfin is $39 a month Plus or $79 Premium. The costlier product is the one aimed at fundamental research, which is worth noticing if that is what you actually do.
Choose TradingView if your process is chart-driven, or you want the best free charting available anywhere.
Choose Koyfin if your process is fundamentals-driven and you want macro context alongside company financials.
Most people comparing TradingView and Koyfin are really asking a question neither answers: how do I know whether this company is worth owning?
The problem they share. One shows you what the price has done. The other shows you what the financials have done. Neither tells you whether the business behind them is worth owning, which is the only question that survives a bad year. That gap shows up at exactly the wrong moment. When a holding falls 30%, you cannot tell a broken business from a temporary drawdown, because you never built the model the thesis rested on.
TradingView is built around price. Charts describe what a stock has done and, if you believe in technicals, what it might do next. Neither question is about whether the company behind it is worth owning.
Stock Simplifier answers the other half: the business model, the durability of the advantage, the quality of management and what the thing is actually worth.
Most long-term investors who use both keep TradingView for entries and use a research tool for the decision to own at all.
Koyfin gets closer to a Bloomberg terminal than anything else at retail pricing, and like a terminal it makes no judgements. Dashboards this powerful assume you already know which metrics matter for this business at this stage.
Stock Simplifier does that interpretation alongside you, adapting the framework to the company's lifecycle phase, and saves the result as work you can revisit.
There is also the free-tier question. Koyfin's has been cut back to two watchlists, two screens and two years of financials. Stock Simplifier's free plan covers a full analysis with five years of financials and no card.
A guided wizard walks you through seven steps for any stock: the business model, its lifecycle phase, the moat, management, growth, risk and valuation. Real data from Fiscal.ai populates each step, the framework adapts to the type of company, and each concept is explained where it appears. You review, score and decide.
Where it falls short. It will not hand you a stock pick. It covers US-listed stocks only. There is no community, no earnings call transcripts and no portfolio tracker. If any of those is why you subscribe today, keep what you have and add this alongside it.
