Screentell

Definition: Screentell is a browser-based screen recording and video editing SaaS tool (Software-as-a-Service) that leverages Web APIs for zero-install operation. It combines real-time screen capture, multi-track editing, and cinematic post-production in a single browser tab.
Core Value Proposition: It eliminates complex desktop software dependencies for creators needing professional-grade tutorials, enabling studio-quality product demos with 3D effects, annotations, and privacy-first local processing entirely in the browser.

Cinematic 3D Transforms: Uses WebGL and Three.js to apply dynamic 3D rotations, scaling, and perspective shifts to screen recordings. Users manipulate keyframes on a timeline to create Hollywood-style motion paths, depth effects, and immersive transitions without rendering delays.
Dual-Stream Recording Engine: Captures screen activity and webcam footage simultaneously as separate tracks. Leverages the MediaRecorder API for lossless compression, allowing independent editing of screen/camera layers post-recording (e.g., resizing face cam, adding borders).
Vector-Based Stickers & Annotations: Offers SVG-powered hand-drawn shapes, arrows, and text bubbles with granular customization (color, border radius, opacity). Supports PNG/JPG uploads for custom stickers, all editable via a non-destructive layer system.
Local-Only Processing: Executes all video encoding/decoding client-side using WebAssembly and IndexedDB. Ensures zero data leaves the user’s device, with exports rendered directly to MP4/WebM/GIF via the browser’s native media capabilities.
AI-Powered Focus Tools: Automates viewer attention guidance through 2D focus zooms (adaptive cropping) and 3D focus transforms (depth-aware highlighting), driven by path-tracing algorithms that simulate camera motion.

Pain Point: Traditional tools like Camtasia or OBS require installation, platform-specific compatibility, and steep learning curves for basic edits—slowing down content creation.
Target Audience:
- SaaS Product Managers: Creating quick feature demos with polished effects.
- EdTech Instructors: Building interactive tutorials with annotations.
- Marketing Teams: Producing social-ready clips (e.g., TikTok, YouTube Shorts) without designers.
- Support Agents: Annotating bug reports with hand-drawn cues.
Use Cases:
- Recording software walkthroughs with 3D zoom effects to highlight UI elements.
- Editing webinar recordings to split segments, adjust speed, and overlay branded stickers.
- Converting static screen captures into animated explainers for landing pages.

Differentiation: Unlike Loom (limited editing) or Descript (audio-focused), Screentell specializes in browser-native cinematic effects—beating desktop tools in speed and accessibility. Competitors lack real-time 3D manipulation and local-only privacy.
Key Innovation: Patented dual-stream architecture synchronizes screen/camera tracks frame-perfectly, while Three.js integration enables complex 3D animations typically exclusive to high-end software like After Effects.

Does Screentell work on iOS or Android?
Screentell is optimized for desktop browsers (Chrome, Edge, Brave) and unsupported on mobile due to Web API limitations for screen recording.
Can I import videos from other tools into Screentell?
Yes, upload existing MP4/WebM files to leverage Screentell’s 3D effects, stickers, and cutting tools—ideal for repurposing legacy content.
How does Screentell’s lifetime license handle future updates?
Lifetime Plan buyers receive all feature upgrades permanently, including new 3D effects and export formats, with no recurring fees.
What’s the maximum resolution for exported videos?
Pro users export in 1080p HD; free tier caps at 720p. All exports use H.264 encoding for compatibility with YouTube/Social platforms.
Does Screentell support green screen removal for webcam footage?
Not currently; the camera layer supports opacity/position adjustments but lacks chroma keying. Use-cases focus on picture-in-picture overlays.
