How credits work.
Keldura uses a single, transparent credit system for everything that costs compute — transcription, imports, chat, briefings, image generation. One balance, published prices, no surprise meters.
The daily allowance
Every account — including free accounts — gets a daily credit allowance that refills automatically. Use it or not, it resets each day. Paid plans raise the allowance and can add extra credits on top; extra credits are drawn on only after the daily allowance runs out. Your current balance is always visible at the bottom of the sidebar, and the Credit history page itemizes every charge.
What costs credits
Actions are priced individually — for example transcribing a video (by length), importing and indexing documents, asking chat questions, generating briefings, and creating cheatsheet images. The authoritative, always-current list is the live credit price list, which is computed from the same prices the billing ledger uses — the published numbers can't drift from what you're actually charged.
Running low, running out
Keldura nudges you when you've used about three quarters of your allowance. If you hit zero, actions that cost credits pause until the daily refill — nothing is deleted, and your existing knowledge base stays fully readable. To keep going immediately, upgrade to a paid plan with a larger allowance.
Plans
Keldura offers a free tier plus paid plans with larger allowances and additional capabilities (for example, the website chat widget requires a paid subscription). Current plan names, prices, and worked examples of what each allowance buys are on the pricing page. Subscriptions are handled by Stripe; you can change or cancel your plan from the pricing page while signed in.
Common questions
- Do unused daily credits roll over? No — the daily allowance resets each day. Extra credits from paid plans persist until used.
- Will I be charged for duplicates? Re-importing a source previews what's new first, so you don't pay to process items you already have.
- Does reading cost credits? No. Browsing your Library, reading transcripts and summaries, and viewing briefings you've already generated are free — credits pay for new processing.
- Where do I see what I spent? The Credit history page lists every transaction with the action, time, and amount.
