Frequently asked questions.

If you are signed out, open the login page, choose Forgot your password?, and use the newest reset link sent to your email address. If you are signed in, go to Settings > Account > Security. On a smaller screen, open the account menu first.

Go to Settings > Account > Appearance and choose Light, Dark, or System. The change takes effect immediately and persists across your devices.

While signed in, open Settings > API Keys. Give the key a name, optionally set an expiry, create it, and copy the secret from its one-time display. Send it as a Bearer token and deactivate keys you no longer use. Never share a key or put it in public client-side code.

Read the public Developer API guide, browse the interactive API reference, or use the machine-readable OpenAPI JSON or OpenAPI YAML.

Keldura turns the sources you follow into living AI knowledge bases. It imports videos, websites, PDFs, documents, audio, and recurring sources, organizes them into Library collections, and lets you ask questions whose answers cite the source material. A reusable Bot can use selected Library folders as knowledge and talk through Telegram or a Website widget. MCP and the Developer API give your own software direct account-level Library access.

Keldura offers plans with a monthly credit pool, and some plans or promotions may include extra credits. Features, limits, and prices can change, so check the current pricing page. The credits guide explains balances, rollover, spending caps, and where to see usage.

Keldura supports videos, websites, files, cloud documents, Telegram Import, and selected recurring sources. Because the catalog evolves, use the maintained source and monitoring guide for current formats, boundaries, and availability.

Keldura transcribes content in its original language and can translate transcripts and summaries into more than 90 languages. You can also chat with your knowledge base in your own language regardless of the source language.

No. Keldura uses existing captions when they are good, and otherwise transcribes the audio with speech-to-text models. Videos without captions work fine.

Answers cite the source material they are based on, with timestamps for video and audio. You can open any citation and check the original. If a collection does not contain the answer, a well-scoped bot says so instead of inventing one.

Yes. Your Library is private to your account unless you explicitly share a collection, a document, or a bot. Content is processed by AI providers to produce transcripts, summaries, and answers. See the privacy policy for details.

Yes. Collections can be shared with specific people or by link, documents and briefings have public read-only share links, and bots can be published to Telegram or embedded on your website. Every share can be revoked.

Yes. Any collection can be exported as a ZIP containing transcripts, summaries, and metadata. Transcripts support TXT and SRT downloads; stored SRT sidecars are downloaded byte-for-byte, while SRT is safely generated when all transcript lines are timestamped. Individual documents can also be copied, and the developer API offers programmatic access.

You can delete items and collections at any time; deletions offer a short undo window before becoming permanent. To delete your entire account and its data, contact support and we will take care of it.

A collection is a folder in your Library and the unit Keldura works with: you chat with a collection, share it, and give bots collections as knowledge. Library imports can target a collection. Briefings-only monitors stay outside the Library unless you save an item; Library + Briefings combines both workflows.

Chat is you asking questions over your own collections inside the app. A Bot is the same grounded question answering packaged for others: it has fixed knowledge, instructions, and a model, and talks to people through channels like Telegram or a website widget.

Yes, for supported recurring sources. Generally available monitoring covers YouTube channels, YouTube playlists, and website roots. Briefings-only monitoring does not automatically import every item into the Library; Library + Briefings does both. Static uploads stay as they are until you add more.

Yes. MCP and the Developer API provide direct account-level access to your Library; they are not Bot Channels. Create credentials in Settings > API Keys, discover MCP tools with tools/list, and use the Developer API guide for endpoints and examples.

Keldura is a web app that works in any modern browser and installs as a progressive web app on phones and desktops, so it behaves like a native app without an app store download.

Bot conversations draw on the account owner's credit balance. Public usage can vary, so review your Plan & Usage page, set any available spending controls, and use the live credit price list for current costs per action.

The public credit price list shows the active chat models and their current credit costs. When signed in, the model picker is authoritative for the models available to your plan and workflow.

Transcription and indexing run in the background and large imports take time, roughly in proportion to the amount of media. The progress tray shows live status, and anything that fails lands on the Needs attention page with a retry button.

Keldura is in active development: features ship frequently and occasional rough edges are possible. The beta expectations page describes what is stable, what is evolving, and how to report problems.
