Obsidian is a local-first, markdown-based knowledge tool that can work well for investor research when you are willing to design and maintain the vault yourself. KeepRule is an investing workflow: it connects a thesis, risk budget, invalidation evidence, principles, and scheduled review without requiring a plugin stack or backlink convention. Compare them by running one live decision through six checks: thesis clarity, source capture, position-size boundary, invalidation trigger, review date, and post-decision evidence. Keep Obsidian if your vault produces those records reliably; consider KeepRule when graph growth and template freedom create more upkeep than decision clarity.

Pick the smallest next action now: test your bias pattern, run a scenario, or copy a prompt before making a portfolio move.

An Obsidian vault lets you choose folders, properties, tags, canvases, and markdown templates. That freedom suits investors who already have a durable note taxonomy. It also means two stock notes can capture different evidence unless you enforce the same fields. KeepRule starts with a stable decision record: thesis, risk budget, invalidation conditions, action rationale, and review date stay comparable across ideas.
Backlinks can reveal useful relationships among companies, industries, sources, and prior judgments, but a dense graph is not proof that an investment case is complete. Test each note directly: can you find the evidence that would disprove the thesis, the principle governing position size, and the next review trigger? KeepRule makes those decision links explicit; Obsidian requires a naming and linking convention you maintain.
Local markdown files can improve portability and give you direct control over where research is stored. Privacy still depends on device security, backup choices, sync provider, shared-vault permissions, and the plugins you install. Community plugins may change, lose maintenance, or expand access to notes. KeepRule reduces plugin drift but is a hosted service, so do not store brokerage passwords, API secrets, or unnecessary personal data in either system.
Do not migrate an entire vault to solve a checklist problem. Choose one active holding and one watchlist idea, export or copy only the thesis, dated evidence, invalidation triggers, and review history, then run both workflows in parallel for two to four weeks. Compare missing fields, review time, and whether contrary evidence is easier to surface. Keep markdown archives intact until the new workflow proves useful.
Use Obsidian when file ownership, offline access, markdown portability, and open-ended research linking matter most, and you can maintain templates and backups. It is a weaker fit when plugin maintenance, inconsistent properties, or graph browsing routinely replaces a scheduled decision review. KeepRule is not a research-vault replacement; it is most useful when the bottleneck is repeatable investment judgment under pressure.

Yes, especially if you value local markdown files, offline access, and flexible links among companies, industries, filings, and prior decisions. The boundary is process consistency: a large vault can still omit position-size rules or invalidation evidence. Use a required template and audit a sample of notes monthly before assuming the graph represents a complete decision record.
No. Local-first describes where the files can live, not the security of every device, backup, sync service, shared folder, or community plugin. Encrypt and secure devices, review plugin permissions, and avoid storing credentials or excessive personal data. Choose the workflow whose data boundary you understand and can maintain, rather than treating either product name as a privacy guarantee.
Backlinks are useful for discovery, but they do not guarantee that a note records thesis, valuation assumptions, risk budget, invalidation evidence, action rationale, and a review date. Keep a short required checklist beside the graph. If any field is repeatedly missing during volatile periods, treat that as a workflow failure even when the vault has rich connections.
Keep the vault as the source archive and migrate only the decision fields needed for one active holding and one new idea. Preserve original filenames, dates, source links, and exports; do not delete the vault during the trial. After two to four weeks, compare review completeness and maintenance time, then expand migration only if the new workflow produces a measurable process improvement.
A hybrid workflow can make sense when Obsidian remains strong for long-form research and source-linked notes while KeepRule handles pre-action checks, invalidation triggers, and post-decision review. Define one system of record for each purpose and link by a stable company or decision identifier. Avoid duplicating every note, because parallel archives quickly become inconsistent.
Choose one active thesis, check its evidence, invalidation trigger, position-size boundary, and review date, then compare the same decision in KeepRule before changing your vault.
