Frequently Asked Questions

Common questions about AI podcast generation

How does the AI Podcast Generator work?

Simply write your podcast script with speaker labels (e.g., "[S1]:", "[S2]:") and the AI will generate natural-sounding audio with distinct voices for each speaker. The system creates realistic conversations with proper pacing, intonation, and natural speech patterns.

How many speakers can I include in my podcast?

The AI Podcast Generator supports multiple speakers in a single episode. You can create conversations between 2 or more voices, each with distinct characteristics. Label each speaker in your script and the AI will assign appropriate voices.

What makes the AI voices sound natural?

Our AI uses advanced speech synthesis that understands context, emotion, and conversational flow. The generated audio includes natural pauses, appropriate emphasis, and realistic speech patterns that make the podcast sound like a genuine conversation.

How long does it take to generate a podcast episode?

Podcast generation typically takes 50-70 seconds depending on the script length and number of speakers. The AI processes your script and creates a complete audio file ready for download and distribution.

How is this different from NotebookLM?

NotebookLM generates conversations from documents automatically—you have limited control over the script. Imagera gives you FULL script control: write exactly what each speaker says, choose voice personalities, and pay-per-use with no Google ecosystem lock-in. Perfect for creators who want precise content control.

Can I turn my blog posts into podcasts?

Yes! Reformat your blog post as a dialogue between speakers and generate instantly. Blog-to-podcast conversion is trending 267% YoY as creators repurpose content to reach the 619 million global podcast listeners.

What is the pricing model?

20 credits per 1,000 characters of speaker text. Pay-per-use with no monthly subscription. Compare: Podcastle $11.99-39.99/mo, Wondercraft $25-79/mo.

Can I use AI podcasts commercially?

Yes! Full commercial rights included. Publish on Spotify, Apple Podcasts, YouTube, or any platform. Monetize your content without additional licensing fees.

What script format do I use?

Use simple speaker tags: [S1]: for speaker one, [S2]: for speaker two. Example: "[S1]: Welcome to the show! [S2]: Great to be here!" The AI automatically detects speakers and assigns distinct voices.

How big is the podcast market in 2026?

The podcast market is projected to reach $131 billion by 2030 (27% CAGR). 619 million global listeners expected by 2026. 61% of podcasters plan to integrate AI into their workflows. Now is the time to start your podcast—without recording equipment.

Can I create audio for Faceless YouTube channels?

Absolutely! Faceless YouTube is trending with 340% growth in 2026. Create consistent narration without showing your face or hiring voice actors. Generate professional voiceovers for compilation videos, tutorials, listicles, and educational content. Combine with AI video editors for complete faceless production.

How do I turn AI trend content into podcasts?

Perfect for the February 2026 viral trends! Create discussion podcasts about AI Caricatures, Ghibli-style art, or Italian Brainrot memes. Write a two-speaker script discussing the trend, generate with AI voices, and publish. Trending topic + audio content = maximum reach across platforms.

Can I create podcast trailers for social media?

Yes! Short podcast clips are trending on TikTok and Instagram Reels. Create 30-60 second teaser episodes with compelling hooks. The AI generates natural-sounding dialogue perfect for social snippets. Use our Video Generator to add visuals for maximum engagement.

Is this good for LinkedIn audio content?

LinkedIn audio is growing 156% YoY for B2B creators. Generate professional-sounding industry discussions, interview-style content, or thought leadership pieces. The AI voices sound polished and business-appropriate—perfect for personal branding without recording equipment.

How exactly are podcast credits calculated per episode?

Credits scale with the length of your dialogue, at 20 credits per 1,000 characters of speaker text (the [S1]: and [S2]: tags themselves are not counted). So a 1,000-character segment is 20 credits, 2,000 characters is 40, and the maximum single episode is 7,000 characters for 140 credits. You see the character count as you write, so the credit cost is visible before you generate — and there is no monthly fee for months you do not produce an episode.

How long an episode can I generate in one pass?

A single generation accepts up to 7,000 characters of speaker dialogue, which is roughly 1,000–1,200 spoken words or about 7–9 minutes of audio depending on pacing. For a longer show, split the script into segments, generate each, and stitch them together — a common approach for chaptered episodes or multi-topic shows where you want section breaks anyway.

How do I turn a PDF, blog post, or set of notes into a podcast script?

Reformat the source into a two-speaker dialogue: pull the key points from your PDF or article, then write them as an exchange with [S1]: and [S2]: tags where one speaker explains and the other asks follow-up questions. This gives you full control over what is said — unlike auto-summary tools — so nothing is invented and the emphasis matches your original. Paste the dialogue into the studio and generate.

Can I control which voice each speaker uses?

Yes. Speakers are identified by their [S1]:, [S2]: (and further) tags in your script, and each tag is assigned a distinct voice so the two hosts stay consistent across the whole episode. Because you write the script line by line, you decide exactly who says what and in which order — the tool does not paraphrase or reorder your dialogue.

Do the credits for podcasts also cover other Imagera tools?

Yes — one credit balance runs the whole studio. The same credits that generate a podcast episode also cover the Voice Generator for standalone narration, the Video Generator for visuals, and the reel tools. That means you can produce an episode, cut a short audio-plus-video teaser, and render cover visuals without stacking three separate subscriptions.

How much does an AI podcast episode cost, and how does length affect credits?

Podcast generation is priced by the length of your dialogue at 20 credits per 1,000 characters of speaker text, with the [S1]: / [S2]: tags excluded from the count. A single episode can run up to 7,000 characters (140 credits), which is roughly 7–9 minutes of audio. There is no monthly subscription — you spend credits only when you generate an episode.

Script lengthCreditsRoughly equals
1,000 characters20 creditsShort segment or teaser (~1–1.5 min)
2,000 characters40 creditsIntro + one topic (~2–3 min)
4,000 characters80 creditsMulti-topic mid-length episode (~4–6 min)
7,000 characters (max)140 creditsFull single-pass episode (~7–9 min)

For a longer show, split the script into segments, generate each, and stitch them — the same balance also runs the Voice Generator and the Video Generator for teasers.

What does the script format look like, and how do I write a good one?

Scripts use simple speaker tags — [S1]: for the first voice, [S2]: for the second — and the AI assigns a distinct, consistent voice to each tag across the whole episode. Everything you write is spoken as-is; the tool does not paraphrase, summarise, or reorder your lines. That is the core difference from auto-summary tools: you control the exact wording, so nothing is invented.

A good two-host script alternates naturally: give one speaker the explanation and the other the follow-up question, keep sentences conversational rather than written-for-the-page, and add short reactions ("right," "exactly," "wait, so…") to make the exchange feel live. Read a draft aloud before generating — anything that sounds stiff on the page sounds stiff in the audio. For a step-by-step build, see the guide on how to create a podcast with AI.

How do I turn a PDF, blog post, or study notes into an episode?

Reformat the source into a two-speaker dialogue. Pull the key points from your PDF, article, or notes, then rewrite them as an exchange: one speaker explains a point, the other asks the clarifying question a listener would ask. This keeps you in control of emphasis and accuracy — you decide what makes the cut instead of an auto-summarizer guessing — and it turns dense source material into something that plays as a conversation rather than a read-aloud.

Students use this to convert lecture notes into review episodes they can listen to on a commute; marketers convert a blog post into a discussion episode to reach the audio audience that will never read the original article. Two focused guides walk through both paths: turning a PDF into a podcast and using an AI podcast generator for studying.

When is a script-control tool better than NotebookLM's auto-generation?

NotebookLM auto-generates a conversation from documents, which is fast but gives you limited control over exactly what is said. A script-first approach is better when the wording matters — client work, educational content that must be accurate, branded shows with a fixed tone, or anything where you cannot risk the model paraphrasing a point incorrectly. You trade the one-click convenience for precision over every line.

Against subscription podcast tools, the trade-off is the same as elsewhere in audio: monthly apps often bundle deep editing suites and large voice libraries into a recurring fee, which is good value for daily producers. A pay-per-use model like Imagera's fits creators who publish in bursts and want one credit balance across podcast, voice, and video rather than a standing subscription. Once an episode exists, you can even repurpose it — the guide on turning a podcast into reels covers cutting audio into short vertical clips for social.
