My Second Brain is the knowledge system around the work. I keep project notes, decisions and operating instructions in Obsidian, use qmd to retrieve them, and give recurring practices a consistent structure in a Knowledge Catalog. An assistant can then find the relevant context before starting the next task. This page began with those records.
How it fits into my setupProvider website ↗ · UK availability: not established
It can help with knowledge management, notes. I’ve included it for consultant, developer.
Where a price, access rule, export option or data detail is unclear, I leave it open rather than guessing. A free trial or a lower headline price does not always mean two tools do the same job.
These are category neighbours, not equivalent entitlements or personal endorsements.
Provider prices and your own paid charges are recorded separately. A non-GBP price stays in its billing currency; the budget supports a dated indicative exchange rate.

I show the provider details I could verify first. Anything missing or unchecked stays folded away below, so it is there when you need it without pretending I know the answer.

Report an updateThese fields remain research gaps. An unknown value does not mean no cost, restriction or data transfer.
These records describe a product connection, such as an included entitlement or compatible service. They do not mark a personal recommendation or an equivalent plan.
Rationalisation uses your declared usage and commitments; shared capabilities alone do not prove redundancy.
No independently checked review rating is recorded. Provider case studies and owner experience do not count as independent reviews.

The previous USD 192 annual list price is derived from the announced 50% reduction to USD 96, not a Sideperk observation of an earlier checkout.
Annual list-price difference: -USD 96.00 (one annual payment).
Undiscounted annual billing for the same named add-on. Taxes, exchange rates and individual discounts are excluded; this is a list-price difference, not realised buyer savings.
