How to read with Three·Lens.
Three·Lens is a research and learning workbench for long-term investors. It is built to teach, not to tell you what to buy.
What this is · and isn't
Every company can be read three ways. A Value investor asks if it is cheap. A Growth investor asks how fast it can expand. A Quality investor asks how durable and well-run it is. The same company often looks attractive through one lens and unattractive through another — and noticing where the lenses disagree is where the real understanding lives.
So Three·Lens never hands you a single verdict. It lays out the numbers, shows you exactly how each one was calculated, explains what they mean in plain language, and leaves the judgement to you. It is for education and research. It is not investment advice, and it is built for people who think in years, not for day trading.
Fully managed · nothing to configure
Three·Lens is fully managed — there are no API keys to bring and nothing to set up. Just sign in and read. The AI analysis, the three-lens synthesis, fresh news, market prices, and company filings are all handled for you.
Market data comes from Twelve Data, company filings from the public U.S. SEC, news from Perplexity, and the written analysis from Anthropic's Claude — all managed for you, so everything you see needs no key at all.
The workbench
The workbench is your home. Search a ticker (for example AAPL or MSFT) and Three·Lens runs a multi-stage reading: it identifies the company from SEC records, fetches the latest price, pulls the financials from the filings, and computes the key ratios. A progress panel shows each stage as it runs.
Finished readings are saved to your library as cards — company, price, sector, and the date you read it. Tap a card to open the full dossier; tap again to come back. Your library lives on your device.
Your workbench lists every live market in a searchable picker. You can switch markets anytime there, and your choice sticks until your next sign-in. The Markets setting on the Account page sets your default market — the one you land on when you sign in.
Reading a dossier
A dossier opens with the company's identity and its latest price (end-of-day, with the date shown). Below that are two groups of numbers: Financials straight from the company's SEC filings, and Ratios that Three·Lens computes from those filings and the price.
Under every number is the exact calculation that produced it — the real figures, not a black box. That is the heart of the teaching layer: tap any number to open a short lesson explaining what it means, the general formula, this company's actual computation, and how to read it sensibly.
A reading covers the company’s identity, price, financials and ratios, the written filings analysis, a fresh-news brief, a peer comparison, and the full Value / Growth / Quality synthesis with its evidence. If a piece can’t be generated — missing data or a provider hiccup — the dossier marks that reading “Partial” and everything else still stands.
Your account
The Account page is where everything about your account lives: your plan and usage, family sharing, and which markets appear in the workbench. It’s also where you sign out.
If you ever want to leave, you can delete your account there yourself. Free accounts are erased right away; on a paid plan you can end immediately or at the end of your billing period, and restore any time before then. Erasing removes your account and data from our servers — we keep only the minimal invoice record the law requires us to. The full detail is in our privacy policy.
Glossary · every number, explained
The same explanations you get by tapping a number in a dossier, gathered in one place.
