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 monthly allowance
Every account — including free accounts — gets a monthly credit allowance that renews automatically. Paid plans raise that allowance, and purchased extra credits remain available until used. A separate daily fair-use limit prevents an entire monthly allowance from being spent at once; it resets at 00:00 UTC without refilling or reducing your monthly balance. 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 monthly allowance. If you run out, actions that cost credits pause until the monthly renewal — nothing is deleted, and your existing knowledge base stays fully readable. If you hit the daily fair-use limit first, only new credit-consuming actions pause until 00:00 UTC; the attempted action does not consume your monthly balance. To keep going with a larger monthly allowance, upgrade to a paid plan.
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 credits roll over? Monthly subscription credits renew with the next allowance period; purchased extra credits persist until used. The daily fair-use limit resets each day but is not a separate credit grant.
- 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.
