Guided onboarding, keyboard shortcuts, and contextual help make Anchorline approachable without limiting power users.
How Anchorline keeps your data trustworthy
Ledger entries are immutable, modeled with either balances or collections. Child ledgers let you nest contexts without losing the trail.
Step 1
Append-only entries
Record every change as a new event. Optional context fields and attachments keep decisions explainable.
Step 2
Choose balances or collections
Balances handle anything you add or deduct, including budgets, credits, and resource quotas. Collections handle items you curate with tags, notes, and metadata.
Step 3
Link child ledgers
Create hierarchies for projects, households, or personal categories. Roll-up views summarize child balances while keeping provenance.
Use cases
Anchorline adapts whether you are tracking numbers, objects, or references. Model anything using balances or collections, then drill into hierarchies when you need to.
Finances
Budgets, envelopes, internal credits, or quotas with full append-only history.

“Anchorline gives us provenance for every budget change. We no longer duplicate work across sheets and email threads.”
“Collections let us catalog our gear with notes and photos while balances keep track of maintenance credits. It’s the perfect truth layer.”
Frequently asked questions
Straightforward answers about how Anchorline keeps your data consistent and portable.
What is an append-only ledger?
Anchorline records every change as a new entry. You can replay the sequence of events to rebuild any previous state, which makes audit trails and reviews reliable.
How are balances different from collections?
Balances track quantities that increase or decrease, covering budgets, credits, and quotas. Collections track discrete items with fields, tags, and attachments. Both share the same append-only history.
Can I import or export my data?
Yes. Every ledger exports to CSV or NDJSON with stable IDs and schema definitions. The docs cover column mappings and how to automate imports.
How do child ledgers work?
Attach any ledger as a child to another. Parent ledgers roll up balances and provide consolidated history while preserving each child's append-only entries.
Can I share a ledger with family or collaborators?
Absolutely. Invite others with view-only or append access so everyone sees the same history without risking accidental edits.
What happens if I cancel?
You retain access to exports and can download everything as CSV or NDJSON. We provide walkthroughs for backups and how to migrate later if you return.
