🔍 Quick Snapshot

Very short comparison, mostly yes/no.

🎭 Where Captions / Mirage Shines

Captions/Mirage works well when:

• You want AI talking videos generated from text prompts.
• You are happy filming short, raw, vertical talking clips and letting AI handle subtitles, cuts and style.
• You care a lot about caption aesthetics, templates and emojis on each clip.

There are two main flows.

Prompt → AI actor video (Mirage)

With Prompt to Video, you can:

1. Write your idea or paste a script.
2. Pick a language (up to 39 supported).
3. Choose an AI actor or generate an AI Twin of yourself.
4. Select an Edit style and accent color.
5. Optionally attach media for B-roll.
6. Generate the video and then tweak it in the editor.

The model:

• generates the actor performance,
• adds AI B-roll and images,
• applies transitions, sound effects, music and motion.

Result: a fully AI-produced talking video without needing to record yourself.

One raw clip → auto-edited short (AI Edit)

AI Edit turns a short, unedited talking clip into a stylised video.

Typical AI Edit flow:

1. Import a vertical talking clip (≤2 min on mobile, ≤1 min on desktop, single speaker, no prior edits).
2. Choose a Premium or Basic style from 100+ presets.
3. Pick the language.
4. Let AI Edit auto-apply trims, captions, transitions, music, AI images, B-roll and motion graphics.
5. Open the timeline to tweak shot styles, captions, colors, B-roll and music.

This is strong for:

• short talking-head clips for TikTok, Reels and Shorts,
• UGC-style ads and explainers,
• creators who like to pick a visual template and stick to it.

Chat-based edits & caption styling

Inside a Captions project you can:

• use chat prompts like add chill music, change font to Comic Sans, generate B-roll about duck soaps, replace background with this image,
• attach images and videos to guide edits,
• iterate with prompts like make it softer or use a different font.

You also get detailed control over:

• caption colors, backgrounds, stroke and shadow,
• emoji size, timing and position,
• word splitting, lines per page and transitions,
• caption templates (including custom templates you save).

Where Captions is not trying to be the full answer:

• no camera-roll library or automatic ingestion,
• no carousels, infographics or text-only posts,
• no content calendar, scheduling or cross-platform analytics.

It is a production tool for: prompt/clip → styled talking video or AI actor video.

📱 What Rkive Is Designed For

Rkive exists for camera-roll-first creators, founders and brands who want the whole pipeline to be automatic by default:

• You record throughout the day on your phone: talking clips, screen recordings, B-roll, product shots, selfies.
• Your raw material lives in your camera roll, not in a single desktop project.
• You want AI to handle the whole edit by default, and you just tweak the result.

Rkive behaves less like a single tool and more like a content OS: the place where your footage, edits, schedule and analytics live together.

📂 Camera-roll first + unlimited cloud

• Rkive syncs your camera roll (with your permission) on iOS and Android.
• All media and posts go into unlimited cloud storage, acting more like a searchable content brain than individual files.
• Your library stays in sync across web, mobile, desktop and Vision Pro.

🧠 Post-level, prompt-driven editing

With Captions, prompts mostly:

• generate fully AI actor videos, or
• tweak a single project’s fonts, music and B-roll.

With Rkive, prompts define the final post across many real clips and images:

• Make a 30s punchy short with big subtitles, quick cuts and a zoom-in on each key line.
• Create a 5-slide carousel summarising these clips with bold titles and simple charts.
• Turn today’s talking clips into a LinkedIn-style text post plus one supporting frame.

Rkive’s multi-agent system decides:

• which clips and images to use,
• how to cut, pace and sequence them,
• where to place subtitles and overlays,
• which layouts to use for the chosen format.

You describe outcomes; the system proposes a finished draft.

🎛️ Many clips → any finished post

Rkive is built to think in posts, not single clips:

• mix selfie talk clips, product B-roll, screen recordings, photos and screenshots,
• output:
  • short vertical videos for Reels, Shorts and TikTok,
  • carousels and infographics,
  • text-first posts for LinkedIn, Threads or X.

It is tuned for daily, mixed-format output, not just one stylised talking video at a time.

✏️ Manual control when you want it

The default is autopilot, but Rkive does not lock you out:

• open any draft in a simple timeline to tweak cuts and timing,
• edit subtitle text, fonts and layout,
• move or resize overlays, stickers, product shots and logos,
• fine-tune framing, zooms and pacing when you care about the details.

You get editor-level control on top of automation, instead of choosing between magic button or full manual.

📅 Scheduling & posting built-in

Rkive does not end at export:

• you see a feed of your own Rkive-made posts — like your social feed, but editable,
• double-tap to schedule directly from the feed,
• open a post to adjust copy, visuals or timing without rebuilding it,
• use the content calendar to move slots, duplicate posts or adapt them by account.

📊 Analytics that look at everything

• Rkive ingests performance across your connected social accounts,
• it tracks posts created inside and outside Rkive,
• AI highlights patterns: hooks that work, best lengths, formats and posting times.

You are not juggling apps; you see one cross-platform view inside the same workspace that creates the content.

💻 Works on all your devices

• Web app in the browser,
• iPhone, iPad, Android phones and tablets,
• macOS and Apple Vision Pro.

Wherever you film or review, your workspace stays synced.

⏱️ A Day with Each Tool

A day with Captions / Mirage

• Jot down a script idea or outline.
• Use Prompt to Video to generate an AI actor video, or record a short raw vertical talking clip on your phone.
• Run AI Edit with a style preset to get captions, AI B-roll, transitions and music.
• Use chat-based editing to change fonts, colors, background or add specific B-roll.
• Export the final video and upload it manually to TikTok, Reels, Shorts, YouTube or ads manager.

This is ideal if you want AI-generated presenters or highly styled talking clips and you are fine handling posting and analytics elsewhere.

A day with Rkive

• Film throughout the day: quick talking clips, product shots, screen recordings, behind-the-scenes, B-roll.
• Rkive syncs your camera roll in the background.
• Its agents build:
  • short videos,
  • carousels,
  • infographics,
  • text-first posts.
• You open Rkive and see a feed of ready-to-publish posts.
• Double-tap to schedule them, or open the editor to tweak details.
• In the calendar, you can reschedule, duplicate or adapt posts for other social accounts.

This is the setup when you want continuous, multi-format output without dedicated editing sessions.

🚀 When Captions Is Enough vs When Rkive Is the Upgrade

Use Captions / Mirage if:

• you want AI actors / AI Twins reading scripts for explainers or ads,
• your main assets are short vertical talking clips you want to stylise,
• you value caption styles, emojis and templates on a per-clip basis,
• you are fine handling storage, scheduling and analytics in separate tools.

Use Rkive AI if:

• most of your content starts in your camera roll, not as one clip or script,
• you want prompt-driven editing across many real clips and images,
• you prefer to tweak strong drafts rather than build every edit by hand,
• you want editing, storage, scheduling, auto-posting and analytics in one workspace,
• you are publishing daily across several platforms and want a camera-roll-first content OS, not just an AI actor app.
