Tell Claude to stash something, it's filed. Ask for it back, you get it instantly — for a fraction of what dragging it out of Notion costs.
The minute you run real work through Claude, the same thing breaks: your data lives in Notion or a CSV you re-upload every time, and pulling it back is slow, pricey, and won't even return enough rows.
Big Notion stores choke and won't return the rows you actually asked for.
Every query drags properties, version history and metadata into the context. You pay for all of it.
The bigger the store, the worse it gets — and you watch your credits drain doing it.
Stash does one thing well, on purpose. Here's where it earns its keep first.
Sync that fat Notion database to Stash and search it for a fraction — and actually get every row back.
Keep your scheduled jobs as rows: when to run, does it repeat, what to do, how to report. Claude just checks the one list. No task-per-task madness.
Great call? Just say "stash it." Filed in a second, pulled back whenever, with a plain page to glance through.
Custom instructions are tiny. Notion is heavy and slow. Stash is the layer in between: a standing context that loads who you are, fresh, every time you open Claude.
Your role, who you work for, your writing style, your top tasks, your OKRs — pulled in one cheap call. Add a single line to your custom instructions and every new chat already knows you.
You don't maintain it — Claude keeps it current. Turn it off whenever.
