Slipstream
A budget you can hold yourself to. Finally.
Slipstream is plan-vs-actual budgeting with a real monthly rhythm: set your plan in minutes, watch one honest number all month, and close with a review that shows exactly what happened — down to where every dollar of surplus went. Capture spending from anywhere, including straight from your AI assistant.
You're on the list — we'll be in touch.
Early access is invite-only while we polish. No spam, ever.
A plan, not a rear-view mirror
Other apps show you where money went. Slipstream holds a monthly plan and tells you whether you're beating it.
One honest number
"Tracking $140 ahead of plan." Untracked spending counts against you — the headline never flatters.
Your agent does the typing
"Log $14 lunch" from Claude or any MCP-capable assistant. Known payees file themselves.
Your data isn't the product
Real double-entry books, kept for you. No ads, no selling your transactions. A fair price instead.
