AI research

Research beyond the numbers.

Figures say what happened. The AI research reads them together with the business behind them: how durable a company’s advantage is, how its latest income statement holds up, where its strengths and risks lie. Every analysis carries its date, its model and how confident it is. It runs on Anthropic’s Claude.

Example of an AI analysis · Illustrative data

The moat rating names its sources — network effects, switching costs, patents, scale, brand — each with its strength, and how confident the rating is. Shown: Apple Inc., from the app’s sample data.

Portfolio analytics

See what the numbers are telling you.

Company figures and your own portfolio, read the same way: what is strong, what is weak, what it costs and how it moved — each figure with its date and its basis.

A company’s health: one overall score out of 100 and six dimensions on sector-adjusted thresholds. Apple Inc., sample data.
The key figures behind it

Health scorecard

Core

Financial strength in six dimensions, each with the figures behind it and thresholds adjusted to the company’s sector. Funds get a score of their own from cost, fund size, age and concentration.

  1. Profit
  2. Growth
  3. Signals
  4. Balance
  5. Cash
  6. Valuation

How the score is built →

Fair value

Several valuation methods side by side, and how far they agree — a range with its uncertainty rather than a single number.

Core

How the fair value is built →

ETF X-Ray

Look through your funds to their regions, sectors and the holdings they share — with each other and with your stocks — and to what they cost each year (TER). The holdings data comes directly from the fund issuers.

Core

Stock screener

Turn an investment idea into explicit criteria — valuation, growth, balance sheet, size, region — and see the companies that meet them.

Free: 13 criteria · Core: 22 · Pro: 23

Performance and risk

Time- and money-weighted return, real return after inflation, Sharpe ratio and maximum drawdown — and the chart against benchmarks such as the MSCI World, the S&P 500 or the DAX.

Free

Market regime

Where each holding stands against its 52-week high: at the high, in a pullback, a correction or a bear market.

Free for your 5 largest positions · Core for all

Compare

Any instruments on one chart, linear or logarithmic, with their fundamentals side by side.

Free: 2 lines · Core: 5 · Pro: unlimited

News on your holdings

Headlines filtered to the companies you own, limited to investor-relevant stories.

Core

The platform

From your accounts to your decisions.

Four steps in one place: what you own comes together, the overview explains it, each holding has its research, and your reasons stay on record.

  1. Bring your investments together

    Connect banks and brokers through finAPI and crypto exchanges by API key (Core); cold wallets and file import work on every plan. FinTS banks refresh overnight, screen-scraped brokers when you start a sync.

  2. Understand your portfolio

    The overview shows value, cost basis and gain, what changed today and how the portfolio divides. Net worth adds property, precious metals and loans, and you can compose further dashboards from widgets.

  3. Investigate your holdings

    Every holding has its page: the company’s figures and health, fair value, news and your trades on the chart — on Pro also the AI research.

  4. Track your decisions

    Note why you bought in the investment diary (Free). On Pro, the AI thesis review checks each thesis against new figures, and price alerts tell you when a price crosses your level.

Sample data

The Portfolio page: returns, risk and every position grouped by holding type. A sample portfolio.

Security & privacy

Your data is yours. Period.

We built foliologic. with privacy as a core principle, not an afterthought.

“Can foliologic. read my portfolio?”

We cannot decrypt your encrypted portfolio.

When you connect a bank or a crypto exchange, the access and holdings data the sync needs are processed on our servers. The holdings data is then stored encrypted in your portfolio, the access data on our servers for later syncs.

How it works

Your portfolio is encrypted in your browser with AES-256-GCM, under a random key created on your device. Your password unlocks a wrapped copy of that key, your recovery code a second one; our servers hold only these wrapped copies and data we cannot decrypt. For syncing we keep, for a bank, the login of your account at finAPI — not your online-banking login — and, for an exchange, your API key and secret, encrypted with a server key. We delete an exchange’s key when you disconnect it, the finAPI login when you disconnect your last bank, and both when you delete your account.

“Can you see my bank login?”

Never — it never reaches us.

You enter your bank credentials on the page of finAPI, a BaFin-licensed German account information service — never with us. The connection can read, never move money.

How it works

When you connect a bank, you enter your credentials on the secure page of finAPI — a BaFin-licensed German account information service — never on foliologic. Your login never touches our servers, so there is nothing for us to see or store. And the connection is read-only: it can read balances and holdings, but it can never move money.

EU data storage

Your encrypted portfolio is stored on servers in the EU (Supabase, Ireland). Prices come from Twelve Data and the AI features run on Anthropic, both US providers: when you use an AI feature, the data it needs is sent to Anthropic for that request.

AI data isolation

Your portfolio data reaches the AI only when you use an AI feature, and Anthropic’s commercial terms exclude it from training their models. What the AI writes about your portfolio is kept only inside your encrypted portfolio and on your device. Ratings that describe a company rather than you — moat, SWOT, income grade — are cached per company for everyone, with no link to any portfolio.

No data selling

No ads, no tracking pixels, no affiliate deals — and your financial data is never sold.

German team

Built by a team in Berlin and operated by foliologic. UG (haftungsbeschränkt), a registered German company — real people, real accountability, a real Impressum.

Why foliologic. exists

foliologic. is a portfolio tracker and research tool for investors who want to manage their wealth on their own terms.

We believe good investment decisions don’t start with hype, gut feeling or blind recommendations — they start with understanding. That is why foliologic. helps you truly see through your portfolio: performance, risks, overlaps, company quality and the connections between them become visible and comprehensible.

We are funded by subscriptions — not commissions, kickbacks or paid placements. Your data is there to help you understand your portfolio — it is not our product.

Who is building it

We are two independent founders from Berlin, building foliologic. with one clear goal: making financial understanding accessible to more people.

We believe investors shouldn’t just manage their wealth — they should truly understand it. So we are building a tool that brings portfolio analysis, research and transparency together in one clear interface.

foliologic. is not a broker, not a forum and not investment advice. We give no buy or sell recommendations — we help you ask better questions, recognise the connections and handle your wealth on your own terms.

Our mission: to take professional financial understanding out of its niche — and make it accessible to everyone who takes their portfolio seriously.

Prices are per month unless marked /yr (per year). Data as of 26 October 2026, from each provider's own pricing, product and help pages; ✗ means not listed in the provider's published features, — means we found no statement by the provider. All information has been compiled with care. Despite thorough research, we cannot guarantee the accuracy, completeness, or timeliness of the information presented. Feature availability and pricing of third-party products may change without notice.
