Reelful, an iOS app created by former Snapchat engineer Kate Deyneka, automatically converts photos and video clips into ready-to-post short-form videos for social media—complete with AI-written scripts, voiceovers, captions, and music.
Users describe the story they want to tell, record a voice sample, and select media; Reelful handles the rest, including animating still images into video.
The app targets busy founders and business owners who want to build their personal or company brand but lack time for traditional video editing.
What happened
Reelful, a new iOS app founded by Kate Deyneka (former Snapchat machine learning engineer), uses AI to automatically transform photos and video clips from your camera roll into polished short-form videos ready for TikTok, Instagram Reels, and YouTube Shorts. Users enter a prompt describing their story, record a 30-second voice sample, select media, and the app generates a complete video with script, voiceover, captions, music, and sound effects—all editable via chat.
Why it matters
Video editing has been a barrier for creators who lack technical skills or time. Reelful targets founders and business owners who need consistent social content but struggle to find time—a salon owner with footage of services and transformations, or a founder who records interviews at events, can now publish polished videos in minutes rather than hours spent in traditional editors. The app reflects a broader shift toward AI agents that automate content creation entirely, letting creators focus on capturing moments rather than editing them.
What to watch
Reelful is currently iOS-only; Android and web versions are planned. Pricing includes one-time bundles ($15 for five videos, $43 for 15, $90 for 33) and subscriptions ($25/month for 10 videos with the Creator plan, $50/month for 25 with Pro, or $100/month for 60 with Studio). The app is part of a16z's Speedrun program.

Reelful enters a market where AI-driven content creation tools are already reshaping how creators produce short-form video. The app is part of a broader wave that includes competitors like Opus Clip and Captions—services that recognize a real friction point: traditional video editing software demands technical skill and time investment that many aspiring creators cannot spare. Kate Deyneka, who built video and image models at Snapchat, left that platform specifically to address this gap. Her observation—that founders and business owners have rich content (events, interviews, product footage) but no bandwidth to edit it—targets a real user segment with immediate financial incentive to automate the process. The startup's inclusion in a16z's Speedrun program signals investor backing for the thesis that agentic video editing (where the AI agent orchestrates the entire workflow from script to final cut) represents the next evolution beyond traditional tools. The pricing structure—mixing credit-based and subscription models—suggests the team is testing different user retention and monetization curves. Reelful's current iOS-only availability reflects typical startup sequencing, though the planned Android and web expansion will be necessary to reach the full addressable market of creators across platforms.
