Best note-taking for investors
The best note-taking apps for investors
Brief Equity is the overall pick for investors who take notes on stocks. Every stock gets a true notebook: a full editor with headings, tables, checklists, and callouts, in chapters and pages. The notebooks sit in a research library that works like a database, with your own columns in 7 types, stages, and tags, any of 182 market metrics beside them, and a table or a board to lay them out. A passage from an earnings call or a block of financials saves into a note with a link back to the source. Notes link to each other with backlinks, a knowledge graph maps your watchlists, stocks, notes, and funds, and all your notes export as one folder of Markdown files. Obsidian is the pick for plain Markdown files kept on your own disk, and Notion for a general wiki shared by a team.

The pick for each use case
A notebook for every stock, beside the market
Best pick: Brief Equity
A true notebook for every stock: a full editor, not an afterthought, with headings, tables, checklists, and callouts, in chapters and pages. Each notebook is a row in a research library you build like a database, with your own columns in 7 types, stages, and tags beside any of 182 market metrics, filtered by any column and laid out as a table or a board. Select a passage in an earnings call or a press release and it saves into a note as a callout with a back-link to the exact spot; a block of financials saves as a table. Notes link to each other with backlinks, a knowledge graph draws your watchlists, stocks, notes, and the funds you follow as one map, and all your notes export as one folder of Markdown files.
Plain Markdown files on your own disk
Pick for this job: Obsidian
Obsidian stores notes as Markdown-formatted plain text files in a vault, a folder on your own computer, so other text editors can open them too. Its links, graph view, and Bases core plugin, which shows notes as tables or cards with filters and formulas, all work on those files. The app is free without limits and needs no sign-up; Sync, for notes across devices, is $4 a user a month billed annually (as of October 2026).
A general wiki shared by a team
Pick for this job: Notion
Notion describes itself as a connected workspace for wikis, docs, and projects. A team keeps its pages in teamspaces and can invite guests to single pages, and its databases carry formulas, relations, and views as a table, board, calendar, or timeline. The Free plan gives one person unlimited pages and blocks, and Plus is $10 per member a month on yearly billing (as of October 2026).

Who Brief Equity is for
It is built for…
- Investors who write a thesis for each stock and want it beside the filings, the calls, and the numbers.
- Readers of transcripts and press releases who save quotes and figures as they go, with a link back to the source.
- Anyone keeping a research library for years, with their own columns, stages, and tags.
- Investors who value a company themselves and want the model next to the notes.
Notes that start from the source
Most investing notes start from a source: an earnings call, a press release, a filing, a set of financials. Brief Equity puts the notebook beside it. One feed carries news from 16 outlets, press releases, earnings-call transcripts, SEC filings, insider trades, and analyst ratings for every ticker on your watchlists, and the notebook sits beside the stock, the chart, and the feed while you work.
That is what Brief Equity adds to a notes app: the market around the notes. A quote you save keeps a link back to the exact spot, figures you save arrive as a table, and your DCF and EV/EBITDA models are built on the same stock in the same workspace. Most investing notes start from a primary source, so keeping the notes and the sources in one place saves steps every time.
How Brief Equity treats notes
Every stock gets a true notebook. It is a full editor, not an afterthought: headings, tables, checklists, and callouts, written in books, chapters, and pages. Link one note to another, and turn on Backlinks to see every place a note links to or embeds another. Briefs hold standalone write-ups for a theme, a sector, or a macro call.
The notebooks sit in a research library that works like a database. The library is a table with a row for every stock you research. Add your own columns in 7 types (text, number, select, multi-select, date, files, or links) with your own options, or a preset such as Catalyst, Risk Level, or Price Target in one click, and put any of 182 market metrics beside them. Filter by any column, sort by one, or lay the same stocks out as a board with lanes by a field such as Stage or Conviction.
Reading a transcript or press release, you select a passage and save it into a note as a callout, on any page or a new one, with a back-link to exactly where it came from. A block of cells from the financials saves as a table, and a chart or a model's valuation card saves as an image, so every claim in your thesis traces back to its source.
The knowledge graph draws your watchlists, stocks, briefs, chapters, pages, and the funds you follow as one map that grows as you work. Toggle node types, scope it to one watchlist, show only the stocks that have research, or focus a fund to see where its holdings overlap yours.
Your notes stay yours
Before you commit years of notes to any app, check that you can take them out. Brief Equity exports every note from Settings as a folder of Markdown files, organized by book and chapter. Your writing and tables leave as plain text that opens in any editor.
Coming from Notion or Obsidian
A page per company, properties on each note, links between pages: if you keep notes in Notion or Obsidian today, Brief Equity's shape will feel familiar. Notion databases carry properties, formulas, and relations, and Obsidian's Bases core plugin shows notes as a table with filters and formulas (as of October 2026).
Brief Equity keeps the page per company, the properties, and the links, and adds the market around it. Any of 182 market metrics sits beside your own columns, the feed brings each company's calls, press releases, and filings, a passage saves into a note with a link back, and your DCF and EV/EBITDA models sit on the same stock. Backlinks will feel familiar from Obsidian, except here they reach past your notes to your tickers, watchlists, and funds.
