CaptionBolt Review: Auto Captions for a One-Time $39

What CaptionBolt is

CaptionBolt is a captioning and video-finishing tool for creators. According to the listing, it is built for people who want to finish footage without learning a full editing suite. You upload a video you have already chosen, and the tool transcribes it, lets you correct and position the captions, and exports the result.

The listing is clear about what it does not do. It does not find clips inside long recordings, translate captions or dub audio. Think of it as a finishing step, not a content-repurposing engine.

There was no product demo video for this review, so everything below comes from the AppSumo listing. We have not tested the tool hands-on.

Key features

Based on the listing, the main capabilities are:

• Transcription-based captions. Successful transcription uses processing minutes based on your video’s length.
• Caption editing. You can fix the words, move the captions and preview the video before export. Text edits leave your audio alone.
• Resize and export. The listing says all tiers support watermark-free MP4 export up to 4K, when the source and framing allow.
• Subtitle and text files. Depending on tier, you can export TXT, SRT, ASS and VTT.
• API and automation (top tier). The highest tier adds a REST API with webhooks and an MCP server for AI agents.

One caveat from the listing: you need to check each platform’s on-screen buttons yourself. The tool won’t stop captions from landing under a platform’s interface elements.

How it works

The listing describes a simple default path that keeps captions, resize and export close to the surface:

1. Upload a video within your tier’s length and file-size limits.
2. Let CaptionBolt transcribe it, which draws on your monthly processing minutes.
3. Correct any wrong words and move the captions where you want them.
4. Preview the video, then export your MP4 and any subtitle or text files your tier includes.

Projects stay in your list for only 14 days after creation. The listing says CaptionBolt isn’t a permanent backup, so download your files promptly.

Pricing and the AppSumo deal

The deal is a lifetime license with three tiers. Each includes all future plan updates, and you must activate your license within 60 days of purchase. AppSumo’s 60-day money-back guarantee applies. The deal ends on 27 October 2026.

	$39 (list $468)	$119 (list $1,548)	$219 (list $2,748)
Minutes per month	60	400	1,200
Max video length	5 min	10 min	20 min
Upload limit	500MB	1GB	3GB
Concurrent jobs	1	2	3
Exports	MP4, TXT	MP4, SRT, ASS, TXT	MP4, SRT, ASS, VTT, TXT
API, webhook, MCP	No	No	Yes

The listing’s plan table runs from largest to smallest. We matched the columns to tiers using the export FAQ, which says Tier 1 has MP4 and TXT and Tier 3 adds VTT. Check the checkout page to confirm.

Keep the limits in mind:

• Minutes reset monthly with no rollover.
• Each video is also capped by length and file size.
• Codes can’t be stacked, and each license is for one user.
• The list prices are the vendor’s own figures. Treat them as marketing anchors rather than proof of value.

Who it’s for (and who should skip it)

A good fit:

• Solo creators who post short videos and want captions without opening a full editor.
• Anyone who already picks their own clips and just needs a quick caption, resize and export step.
• Developers or automation-minded users who may want the API and MCP server on the top tier.

Consider skipping if:

• You want a tool that finds highlights in long recordings, because the listing says it doesn’t.
• You need translated captions or dubbing.
• You work in a team. Licenses are single-user.
• You publish long videos. The $39 tier caps videos at 5 minutes, and even the top tier stops at 20.
• You need a permanent archive of your projects.

The $39 tier gives you 60 minutes a month, or roughly a dozen 5-minute videos if you use every minute. That is enough for light use. Heavier posting schedules will need a higher tier, and the price rises quickly.

Because this is a young product category with many caption tools, the 60-day guarantee matters. Use it to confirm that caption accuracy, styling and platform framing meet your needs before the refund window closes.
