Best AI tools to turn podcasts and webinars into blog posts in 2026
Your recordings already hold the opinions and examples a good post needs, and these five tools get them onto the page.

TL;DR
- The best AI tool to turn a podcast or webinar into a blog post depends on where the recording starts: Contengi if you want an on-brand article published to your site, Castmagic for bulk repurposing, Descript or Riverside if you also edit the video.
- Contengi takes an uploaded call or podcast and returns a summary, key quotes, and angles, then writes the post from your brand knowledge base. It starts at $50 a month plus your own Anthropic key.
- Castmagic starts at $19 a month billed annually and turns one recording into blogs, newsletters, LinkedIn posts, and show notes.
- Descript and Riverside are recording and editing tools first, with AI show notes and drafts on top, from $16 and $24 a month billed annually.
- Whatever you pick, the transcript is raw material. A post that ranks still needs your opinion, a structure built for the question people search, and an edit for AI tells.
An hour-long webinar holds thousands of words of things you said out loud, and most of them never leave the recording. That's a full larder and nothing cooked.
This list covers five AI tools that turn podcasts and webinars into blog posts, in no specific order after the first. We built Contengi, so it goes first, and every other tool here beats us at something. Each pick ends with who it suits, and prices come from each vendor's own pricing page as it reads in October 2026.
What makes a good podcast-to-blog tool?
A good tool does three jobs: it transcribes accurately, it finds the parts worth publishing, and it writes them up in a voice that sounds like you. The first job is solved. The second and third are where tools differ.
Transcripts are the closest thing a small team has to free non-commodity content, which is why we wrote a full guide on how to use transcripts for content. The tool you pick decides how much editing sits between the recording and the published post.
1. Contengi: best for when you want the transcript to become an on-brand post on your own site
Contengi is an agentic content platform. You upload a call or podcast and get a summary, key quotes, and ready-to-use angles, then the blog agent writes the article from your brand knowledge base, tone of voice, and hard rules. A strategist builds that knowledge base with you during setup.
Drafts go through a hard-rule linter before they reach you, and finished posts publish to WordPress, Shopify, Webflow, or a site built with Claude or v0 through Contengi's website integrations. The same transcript can also feed LinkedIn posts and a newsletter issue.
Pricing is from $50 a month with no seats, and you bring your own Anthropic key. Most solo operators spend $25 to $50 a month on the AI. Contengi is in beta. It doesn't record or edit audio or video, so you'll still need something for that part.
Choose it if you record calls or podcasts already and want finished, on-brand articles on your site with less steps in between.
2. Castmagic: best for when you want every format drafted from one recording
Castmagic is built for repurposing at volume. One upload turns into show notes, summaries, long-form articles, newsletters, LinkedIn posts, and quotes, in more than 60 languages. It plugs into Zoom, Google Drive, Zapier, and RSS, so recordings can arrive on their own.
The Hobby plan is $19 a month billed annually with a 30-hour transcription library, Starter is $48 a month billed annually with 100 hours, and Team is $139 a month billed annually with five seats.
Choose it if you publish a weekly show and want every format drafted from each episode in one place.
3. Descript: best for when you edit the video and write the post in the same tool
Descript edits audio and video by editing the transcript, like a document. Its AI co-editor, Underlord, can draft blog posts, show notes, and social posts from the recording, next to tools like Studio Sound and filler-word removal.
There's a free plan. Hobbyist is $16 per person a month billed annually or $24 monthly, with 10 media hours, and Creator is $24 billed annually with 30 hours.
Choose it if video editing is the bigger job and the blog post is a bonus at the end.
4. Riverside: best for when you record and host webinars yourself
Riverside records in up to 4K, transcribes without limits on paid plans, and writes AI show notes and clips. The Webinar plan adds registration, Q&A, polls, and HubSpot sync, so the recording and the repurposing live in one place.
Pro is $24 a month billed annually ($29 monthly), and the Webinar plan is $79 a month billed annually ($99 monthly) for up to 100 registrants.
Choose it if you run your own webinars or interviews and want recording, hosting, and show notes from one vendor.
5. Claude: best for when you want to do it by hand, with a good assistant
Claude, Anthropic's AI model, handles long transcripts well. Paste one into a project with your style notes and ask for an outline, then a draft. You control every step, and you do every step.
Claude Pro is $20 a month, or $17 a month on an annual plan. The free plan includes up to five projects.
Choose it if you turn one recording a month into one post and enjoy shaping the draft yourself.

How to turn one webinar into a blog post this week
- Pick the one question the webinar answered best, phrased the way a buyer would search it.
- Pull the transcript and mark three moments where you gave an opinion or a real example.
- Build the outline around those moments, with headings phrased as questions and the answer in the first sentence under each.
- Draft from your brand rules, so the post sounds like the person on the recording. Our guide to a brand knowledge base for AI shows what to write down.
- Clean the AI tells with the free AI slop cleaner before you publish.
- Repurpose the rest into LinkedIn posts and a newsletter, following the steps in our YouTube transcript playbook.
Frequently asked questions
What is the best AI tool to turn a podcast into a blog post?
Contengi suits teams that want on-brand posts published straight to their site. Castmagic suits creators who want many formats per episode, and Descript or Riverside suit people who also edit the recording.
Can AI write a blog post from a webinar recording?
Yes. Every tool here transcribes the webinar and drafts from it. The draft gets better when the tool knows your voice and you add an opinion the recording didn't spell out.
Is a transcript the same as a blog post?
No. A transcript follows the order you spoke in, and a blog post follows the question a reader searched. Restructure it around that question and cut the warm-up.
How much does it cost to repurpose podcasts with AI?
Castmagic starts at $19 a month billed annually, Descript at $16, and Riverside at $24. Contengi starts at $50 a month plus your own Anthropic usage, which runs $25 to $50 a month for most solo operators.
Will Google rank a blog post made from a transcript?
It can, if the post helps the reader. Posts built from real conversations carry examples and opinions other pages lack, which gives them a better shot than a generic AI draft. Our take on whether AI content hurts SEO covers the rules.
