  • Smooth Subtitle Editing Experience. Captioner is built by content creators, for content creators. We spent hours perfecting the editing experience so you can spend more time on your content and less time on the tools.
  • Import and Align Existing Transcripts. You might already have a transcript written for your video. No problem! You can import it directly into Captioner and we will align it for you. (Think YouTube's auto-sync feature, but better!)
  • Subtitle File Export. Different platforms and editing softwares use different subtitle file formats. We support the most popular formats (SBV, SRT, VTT) so you can add quickly add subtitles into your YouTube videos. You can also choose a font style directly from the editor and get a video export with the subtitles burned in.

The Top Free and Paid Teachable Alternatives For Creators
While Circle offers video and social integrations, itโ€™s missing quite a number of features on the sales and market side. For example, it doesnโ€™t allow you to create in-app sales funnels with customizable landing pages and checkout for selling community memberships. It also doesnโ€™t offer any native or third-party email marketing tools.

  • Collaboration Circles for Developers (2026)
    Circle.so is a platform designed for online communities, with sub-groups, private spaces, etc. Ideal for creating private circles: you could set up an "Angular/React/AI circle" of 5 people and use Circle's functionalities to schedule meetings, chats, shared files. Advantage: more structured, ideal for your 5-person model. Limitation: may have a cost or require configuration. - Source: dev.to / 9 months ago
  • Do you guys know of another platform where people can talk, but is less anonymous than reddit? Allows for more of a sense of connecting with real people in a safe way.
    Https://cptsdfoundation.org/ has a group that you can interact with using https://circle.so/. Membership is 5 bucks a month, and to me, while I was using it, it was a very welcoming community. Source: over 2 years ago
  • Tell HN: DuckDuckGo Search Results have jumped the shark
    Https://circle.so/pricing/ I would guess even if DDG protects your privacy, it would use information (perhaps search and or site history) the browser is broadcasting regardless to filter results it pipes to the end point.

  • Which nocode tool to build an online academy?
    What is the reason you are trying to go custom? https://circle.so this is probably the best platform I have seen. Big and small companies use it (even webflow) so it has great adoption works well. I would stay away from a custom solution when there are wonderful tools like circle out there.
