Documentation
Everything below works in the free, local-first tier — no account, no network.
Looking for the full Help Center? The Ledger Help Center is the exhaustive, self-service guide — getting started, every feature step by step, Obsidian vault sync, the Obsidian plugin, AI, the cloud/Pro tier, security & privacy, pricing, troubleshooting & FAQ, and a "How do I…?" recipe index. The quick reference below covers the essentials.
The left rail (the "spine") groups your pages by folder with a tag cloud beneath. Type in the search box to search-as-you-type across titles, paths, tags, frontmatter values, and body text. Click a result to open it.
Frontmatter renders as a tidy table at the top; the markdown body renders below with headings, tables, code, Mermaid blocks, task lists, and [[wiki-links]]. A meta bar shows tags and backlinks (which other pages link here).
The Edit tab is a split markdown editor with live preview. Ctrl/Cmd+S (or the Save button) commits — and snapshots the prior version into history. Set tags inline.
The History tab lists prior versions. View a line-level diff against the current version, or restore any prior version (the current one is kept too). Hosted mode adds full git history + pull-request review.
The Templates button starts a new page from a real IT-doc template: server/VM asset, network note, runbook/SOP, credential reference, SaaS app, onboarding/offboarding procedure.
Ledger holds zero secret material. Use a password manager (Bitwarden, 1Password, Keeper, Vaultwarden). For each credential, create a credential reference page that links the vault item by URL/ID — never paste the password, key, or seed. If you try to save a page that looks like it contains a secret, Ledger warns you and points you to the vault pattern.
Export a single page as .md, or the whole KB as one portable markdown bundle. It's already files — there's nothing to "get out."
The Cloud button opens sign-in (your DosanjhLabs account, via Clerk). Signed in, Pro features unlock: cross-device KB sync, PR review, MSP multi-client, and "doc reviewed / exists" evidence emission to Sightline. Signed out, Ledger makes zero network calls.
The AI button: paste your own OpenAI / Anthropic / OpenRouter key (stored locally; the browser calls the provider directly). Draft a doc from notes, summarize the open page, or ask questions over your docs with citations. A scrubber blocks pasted secrets before any request leaves your browser.
