Description
CaptionBolt is an AI caption generator and video finishing tool built for the work that starts after filming. It turns recorded talking-head footage into publish-ready social videos through a focused, caption-first workflow, without requiring a traditional timeline-based editor.

After you upload a video, CaptionBolt transcribes the speech, times every line, and applies one of 320 caption styles across six searchable families. Every caption stays editable, so you can review the transcript, import SRT, split or merge lines, remove pauses or filler words, and fine-tune typography, color, motion, placement, and emphasis. The source framing is preserved by default, and you can resize to 9:16, 1:1, 4:5, or 16:9 with crop, blurred, or solid backgrounds, plus optional manual trimming.
Beyond captions, CaptionBolt adds finishing tools in the same workspace: generate an editable Cover from 20 templates and six headline tones, add transcript-matched Smart B-Roll from Pexels or your own media, apply a Logo and Progress Bar, and save reusable Video Templates to keep videos on-brand. It can also draft editable social posts, titles, and hashtags for TikTok, Instagram Reels, and YouTube Shorts, without posting to any account. A separate Transcript workspace handles podcast, interview, and long-form recording transcription into editable, downloadable text.
CaptionBolt is designed for creators, coaches, educators, marketers, social managers, freelancers, and small teams who publish often. It deliberately skips multi-track timelines, automatic viral-clip selection, speaker-tracked reframing, and AI video generation or avatars. The Free plan includes 10 processing minutes per month, all 320 caption styles, the full finishing toolkit, and MP4/TXT exports up to 1080p with a watermark; paid plans add more minutes, longer uploads, watermark-free exports up to 4K, and additional subtitle formats.
