--- title: "Apps that search PDFs, articles, videos and podcasts in one library (2026)" description: "Nine apps compared on keeping PDFs, articles, YouTube talks and podcasts in one library, and on whether search reaches inside video and podcast transcripts." canonical: "https://omphalis.ai/blog/apps-that-search-pdfs-articles-videos-and-podcasts-in-one-library-2026" source: "https://omphalis.ai/blog/apps-that-search-pdfs-articles-videos-and-podcasts-in-one-library-2026" --- # Apps that search PDFs, articles, videos and podcasts in one library (2026) September 29, 2026 · 14 min read > **Quick summary:** If your sources are split across PDFs, articles, YouTube talks and podcasts, the test is whether one app keeps all four and searches inside the transcripts, not only the titles. Omphalis ranks first for people who read, study or research that material, because every source becomes the same readable page, with timestamped transcripts and cited answers from your own library. Recall is the closest all-format alternative if you want summaries and quizzes, Readwise Reader suits heavy highlighters who mostly read text, and Knowbase suits people uploading their own recordings. Snipd is the strongest pick for podcasts, and it is a podcast app only. *We make Omphalis, so weigh its place on this list accordingly. Every other entry was checked against the vendor's own pages on September 29, 2026; prices and features change, so confirm before you pay.* A research project rarely arrives in one format. The paper is a PDF, the useful commentary is a blog post, the clearest explanation is a YouTube talk, and the idea you half remember came from a podcast. Most tools handle one or two of those well and leave the rest as links you cannot search. This guide compares nine apps for students, researchers and professionals who want those sources in one place, on formats kept, search inside transcripts, getting back to the passage, and the free plan. ## Quick comparison | Tool | Best for | Formats it keeps | Search inside transcripts | Starting price | | --- | --- | --- | --- | --- | | [Omphalis](https://omphalis.ai/) | Reading and research across formats | Articles, PDFs (paid plans and trial), EPUBs, Word, YouTube, podcasts, newsletters, notes | Yes, and Ask cites transcript passages | Free; Pro $9/month | | [Recall](https://www.recall.it/) | Summaries, chat and quizzes | Web pages, PDFs, YouTube, TikTok, Vimeo, podcasts, Google Docs | Yes for podcasts, by exact quote; its help docs say podcast timestamps are not yet included | Free; Plus $10/month billed yearly | | [Readwise Reader](https://readwise.io/read) | Heavy highlighters | Articles, PDFs, EPUBs, newsletters, RSS, YouTube, podcast transcripts | YouTube and saved podcast transcripts; no podcast playback | $9.99/month billed yearly | | [Knowbase](https://knowbase.ai/) | Your own audio and video files | PDF, Word, PowerPoint, audio and video files, YouTube | Yes, citations jump to the timestamp | Free; Starter $15/month billed yearly | | [Evernote](https://evernote.com/) | Notes, scans and handwriting | Notes, PDFs, Office docs, images, transcribed audio and video | Transcripts saved as searchable notes | Free; Starter $14.99/month | | [Capacities](https://capacities.io/) | Linked notes with PDFs as objects | Notes, PDFs, weblinks, images, audio | Audio transcripts in Believer early access | Free; Pro $9.99/month billed yearly | | [Notion](https://www.notion.com/) | Teams already in Notion | Pages, databases, clipped pages, uploads | No built-in transcription found | Free; Plus $10/month billed yearly | | [Obsidian](https://obsidian.md/) | Local notes you own | Markdown notes, PDFs, audio and video files, clipped pages | No, search reads notes and canvases only | Free; Sync $4/month billed yearly | | [Snipd](https://www.snipd.com/) | Podcast listeners | Podcasts; YouTube and audio files on Premium | Yes, with speaker identification | Free; Premium $6.99/month billed yearly | ## What to look for - **Every format as something you can read.** A PDF attachment or a saved video link is not a page you can highlight and search. - **Search that reaches inside transcripts.** Test with a phrase you remember from an episode. - **A way back to the moment.** Timestamps, speaker labels and citations that open the passage make a result usable. - **What the free plan covers.** Transcription minutes, answer caps and which formats are free vary widely. ### 1.

[Readwise Reader](https://readwise.io/read) Readwise Reader is a reading app for people who highlight a lot.

[Knowbase](https://knowbase.ai/) Knowbase is built around uploading your own files and asking questions of them. It [takes](https://knowbase.ai/) PDFs, Word, PowerPoint, text files, audio and video files and YouTube links, and transcribes the recordings. **Highlights** - Transcription with speaker identification, exportable as SRT or VTT - [Citations](https://knowbase.ai/features/document-chat/) jump to the exact PDF page or video timestamp - "Chat-All" searches your library plus connected Google Drive, Notion and Dropbox **Specs** - **Best for:** Your own recordings, lectures and documents - **Files:** Up to 1 GB, organized in "Nests" - **Platforms:** Web app - **Price:** Free with 25 queries; Starter $15/month billed yearly ($19 monthly) with 1 hour of transcription.

[Capacities](https://capacities.io/) Capacities treats every source as an object you link to your notes. PDFs are objects you read and annotate, and weblinks get a Reader tab for clean article view. **Highlights** - [PDF analysis](https://docs.capacities.io/reference/media-analysis) on Pro lets you search inside a document and jump to the page - [Audio analysis](https://docs.capacities.io/reference/basic-types/audio), with a searchable transcript, is in Believer early access - [Search](https://docs.capacities.io/reference/search) works offline **Specs** - **Best for:** Linked notes where PDFs and web pages are objects - **Free plan:** Unlimited objects and full-text search - **Platforms:** macOS, Windows, Linux, iOS, Android, web - **Price:** Free; Pro $9.99/month billed yearly ($11.99 monthly). See [Capacities pricing](https://capacities.io/pricing). **Pros** - A generous free plan with offline support - Desktop apps on macOS, Windows and Linux **Cons** - We found no YouTube or podcast transcript feature in its docs - Highlighting PDFs needs Pro or Believer Pick Capacities if you think in linked notes and your sources are mostly PDFs and web pages. ### 7.

It can [store](https://help.obsidian.md/file-formats) PDFs, images, audio and video in your vault and embed them in notes. **Highlights** - The [Web Clipper](https://obsidian.md/clipper) saves pages as files you can read offline, with a template for podcasts - Notes stay on your device as plain Markdown - An audio recorder saves voice recordings into the vault **Specs** - **Best for:** Local Markdown notes you fully own - **Search:** Notes and canvases only - **Platforms:** Windows, Mac, Linux, iOS, Android - **Price:** Free; Sync $4/month billed yearly.

[Snipd](https://www.snipd.com/) Snipd is a podcast app, and only a podcast app: it does not keep PDFs or web articles. For podcasts it is excellent: tap your headphones to save a snip with the audio, transcript and a summary. **Highlights** - Transcripts with speaker identification and automatic chapters - Chat with an episode - Syncs snips to Notion, Readwise, Obsidian, Bear and Logseq **Specs** - **Best for:** Podcast listeners who want to keep what they hear - **Imports:** YouTube videos and audio files on Premium - **Platforms:** Mobile app with CarPlay, Android Auto and Apple Watch support - **Price:** Free with AI features on 2 episodes a week; Premium $6.99/month billed yearly ($11.99 monthly). See [Snipd pricing](https://www.snipd.com/pricing). **Pros** - Saving a moment with a headphone tap is quicker than any reader here - Sync to your notes app is included on the free plan **Cons** - Podcasts only: your PDFs and articles need a second app Pick Snipd if podcasts are your main source, and pair it with a reader for the rest. ## Which one should you pick? **If you read, study or research across formats**, pick Omphalis, and start on the trial if PDFs are central, since Free does not turn PDFs into readable pages. **If you want summaries and quizzes built in**, pick Recall. **If your sources are mostly text and you highlight heavily**, pick Readwise Reader, especially if you want a desktop or e-ink app. **If you work from your own recordings and slides**, pick Knowbase. **If you want notes you fully control**, pick Obsidian or Capacities, and expect to handle video and podcast transcripts yourself. **If podcasts are nearly everything**, pick Snipd and add a reader for your PDFs and articles. ## Frequently asked questions ### How can I search my PDFs alongside video transcripts in one app? Omphalis keeps PDFs, YouTube talks and podcasts as readable pages under one search, and Ask cites the passage it drew on; PDFs are read on paid plans and during the trial. Recall and Knowbase also cover PDFs and video, and Knowbase citations jump to the video timestamp. ### What's the best app for organizing articles alongside podcast notes? Omphalis keeps articles and podcast transcripts in the same Library, with highlights, tags and Collections across both. If you prefer a dedicated podcast app, Snipd syncs podcast snips into Notion, Obsidian or Readwise, where your articles can live. That means two apps, but it suits heavy listeners. ### Can I search inside podcast transcripts? Yes, in several apps. Omphalis, Recall, Readwise Reader and Snipd all produce podcast transcripts, and Recall says you can search its transcripts for an exact quote. Recall's product page promises a timestamp on each transcript segment while its help docs say podcast timestamps are not yet included; Omphalis transcripts are timestamped and labelled by speaker. ### Is there a free app that searches PDFs and YouTube transcripts together? Recall and Knowbase both have free plans that take PDFs and YouTube, with limits on summaries or queries. Omphalis Free takes YouTube and keeps PDF files, but reads PDFs only on paid plans or during the 30-day trial. Capacities and Obsidian are free, but we found no YouTube transcript feature in either. ### Does Obsidian search inside PDFs? Not with its built-in search. Obsidian's help page says search covers only the contents of notes and canvases. You can store and embed PDFs in a vault, but finding text inside them needs a plugin or another app. *Last updated: September 29, 2026* > Also read: [Read podcast transcripts with explanations](https://omphalis.ai/read/podcasts) · [Ask questions about your reading, with citations](https://omphalis.ai/ask) - [Research Tools](https://omphalis.ai/blog/tag/Research%20Tools) - [PDF Reader](https://omphalis.ai/blog/tag/PDF%20Reader) - [Podcast Transcripts](https://omphalis.ai/blog/tag/Podcast%20Transcripts) - [Knowledge Management](https://omphalis.ai/blog/tag/Knowledge%20Management) --- Listed on: [Featured on launched.tools REVIEWED ✓](https://launched.tools/tools/omphalis)
