Seeking Alpha is a US platform with a US lens. Openbook scores UK and US shares on the same 8-factor Reward and Risk model, screens both markets for free, and imports the portfolio you actually hold at a UK broker.
The features a UK investor uses most, side by side. Green is a clear yes, red a clear no, grey a qualified answer.

Four differences that matter more than any single feature.
Seeking Alpha is written by and for US investors, in dollars, around US listings. Openbook covers UK shares natively: prices in pence, LSE and AIM, ex-dividend dates in the UK calendar, ISA and SIPP in the portfolio view. If most of what you hold is on the London market, that is the whole difference.
A single rating hides the trade-off. Openbook reports Reward (Growth, Momentum, Profitability, Valuation) and Risk (Volatility, Financial Solvency, Operational Quality, Size) as two independent scores, so a cheap, fast-growing company with a stretched balance sheet looks exactly like what it is. How the scores are built.
Scores, financial history, the screener and the portfolio tracker are on the free tier, with no card and no article counter. Pro adds factor exposure and deeper analytics for those who want them.
Volume of written analysis. Thousands of contributors publish bull and bear cases on US stocks every day, and the author track records are a genuinely useful signal. Openbook publishes its own insights and lets the numbers do most of the talking. If you want to read ten opinions on Nvidia before lunch, Seeking Alpha is the better product.
An honest split. Both tools are good at something; the question is what you need.
Open a public company page to preview its Reward and Risk scores, factor breakdown, financial history and dividend record. A free account extends access to the rest of the platform.
Yes. Openbook Analytics has a permanent free tier with core Reward and Risk scores, financial history, dividend data, a screener and a portfolio tracker across thousands of UK and US-listed stocks. No card is needed to start.
Partly. Seeking Alpha is strongest on US-listed companies, and UK companies appear mainly through their US listings and ADRs, in dollars. Openbook covers UK shares on the London market directly, with prices in pence and UK dividend dates.
Both score companies on fundamental factors. Seeking Alpha blends its factor grades into one Quant Rating. Openbook keeps Reward (Growth, Momentum, Profitability, Valuation) and Risk (Volatility, Financial Solvency, Operational Quality, Size) as two separate ratings, so you can see an attractive company with elevated risk for what it is.
Openbook covers thousands of UK and US-listed stocks. Full Reward and Risk scores are available for more than 1,500 UK-listed companies with sufficient reporting history; US score coverage is expanding and some newer listings have limited data.
Yes. Export your transaction history from Hargreaves Lansdown, AJ Bell, interactive investor, Freetrade, Vanguard or most other brokers as CSV or Excel and import it; Openbook works out the columns and shows you what it read before saving. Trading 212 also has a direct sync.
For US-focused investors who read a lot of contributor analysis, often yes. For UK investors who want scores, a screener and a portfolio view of the shares they hold at a UK broker, Openbook does that job on its free tier. The "who should use which" section above is our honest split.
No. Openbook is an analysis and education tool. Nothing on the platform is a recommendation to buy, sell or hold any investment.
Core Reward and Risk scores, financial history, dividend data and portfolio tools across UK and US markets, on the free tier.
