How can we help?

Getting started

1. Create your account at knowstash.ai/signup: a name, an email, a password. (You'll also be able to sign in with Google afterwards.)
2. Confirm your email. We send a link; clicking it unlocks your account and drops your free starting credits into the balance.
3. Install the extension from the Chrome Web Store. One click, details below.
4. Open any YouTube video. The KnowStash panel appears beside the player. Stash the video, ask for a note, watch it stream in.

Prefer a bigger screen? Everything also lives in the companion web app. Same account, same library.

Install the extension

KnowStash is on the Chrome Web Store. one click to add it, and it works in Chrome, Brave, Edge, and Arc. Pin it to your toolbar (the puzzle-piece icon), then open any YouTube video and the panel appears beside the player. Our install page has the button and the quick first-run steps.

Core concepts

Monitors, in five minutes

A monitor turns a queue into a standing watch: it checks YouTube on a schedule, pulls in videos it hasn't seen, and, if you ask, stashes them, writes notes, and emails you about it.

1. Open a queue (Queue page in the web app, or the Queue tab in the extension).
2. Add a source under Sources: a YouTube search, a channel (with autocomplete), or a playlist. Set per-check caps and an upload-date floor if you like; Shorts are always skipped.
3. Flip the automations you want: Auto-stash fetches every new find; Auto-note writes a note per video or folds everything into one growing note; Email messages you when something new lands; Newsletter emails a written issue built from the queue's new notes: themed sections, headlines, and short summaries with links.
4. Pick a cadence: one slider, from hourly to weekly. The Email and Newsletter rows keep their own schedule: instant, daily, or weekly, at the hour you choose.
5. Impatient? Check now runs the whole pipeline immediately.

Good to know

• Scheduled checks run on an hourly tick, so a new monitor's first check happens within the hour. Check now if you can't wait. A cadence that isn't a whole number of hours simply waits for the next tick; a check is never skipped.
• Each video is handled at most once per monitor: removing it from the queue won't make it come back.
• A check costs 0.01 credits; whatever it finds is billed at the normal stash and note rates. Paused monitors are free.
• A newsletter issue bills a small flat price only when one is actually sent (see the meter); a quiet stretch with no new notes sends nothing and costs only the check.
• Monitors pause themselves after repeated failures (or if their queue is deleted) instead of burning credits quietly.
• The Activity feed on the queue keeps a running history: every check, find, note, and email, with links.

Credits & billing

Balance and spend

Your balance sits in the profile menu (bottom-left in the web app) and in the extension's Account view, with a per-action spend history next to it. Confirming your email at signup grants your free starting credits, and the little quests under Account pay out more as you explore.

Subscriptions and top-ups

Monthly subscriptions are the cheaper hour: every plan prices video at the same rate per credit, so the tiers differ only in how many credits arrive each month. pick the one that matches what you watch on the pricing page. Top-ups are one-time packs at the walk-up rate, which costs more per credit; they stack with any plan and are meant for the occasional overflow. If you run out most months, moving up a plan is cheaper than topping up. Either way, credits never expire. Buying from Europe you pay in euros, elsewhere in dollars, and prices are shown before tax. Your country's VAT or sales tax is added at checkout. Payments are handled by Paddle, our merchant of record. They run the checkout and send the invoice; your card never touches our servers.

Manage everything under Account → Billing in the web app: change plan (upgrades are prorated, downgrades start at renewal), cancel (you keep the plan and its credits until the period ends), resume, and open the payment portal for card changes and invoices. Refunds are covered by a 30-day money-back guarantee.

Google or password?

Both work. Use whichever matches the address you signed up with. One caveat: Google sign-in only accepts an account's primary address, so if you signed up with a Google Workspace alias or a non-Google mailbox, sign in with your password.

Forgot your password?

Use “Forgot password?” on any sign-in screen (or go straight to the reset page). We email you a reset link; the sender is KnowStash.

Product updates and offers

Occasional marketing email, opt-in per kind: product updates (new features and changes) and offers (discounts and promotions) are separate choices. Pick them when you sign up, or any time under Settings in the web app. Every one of these emails carries an unsubscribe link, and account email (confirmations, password resets, monitor emails you set up) arrives regardless.

Your data

Your stash is yours. The Account page can wipe all your content in one action (your sign-in and balance stay). Want the whole account gone? Email support@knowstash.ai from your account address and we'll erase it completely, usually within days, always within 30. Either way, we'd genuinely like to hear what went wrong first. The details live in our privacy policy.
