11Marketing Copilot
Chat-driven campaign builder that scrapes your product, plans the video, and renders it — the best starting point when you're unsure which tool to use.
Ad Agent
A conversational way to build a talking-head product ad — it asks one thing at a time, renders, then refines the same video from your follow-up messages.
Product Ad Wizard
The form-based product-ad builder for full control: scrape a URL or pick a saved product, edit the script, add B-roll, and render with or without an avatar.
Talking-Head Video
Turn a script into a lip-synced avatar speaking to camera, with burned-in captions — pick an avatar and voice, paste your script, and render.
AI Cast
TikTok-style image-to-video where your avatar IS the subject performing an action — describe the action and scene, and Krex AI composites and animates you in.
Text to Video
The simplest path — type a prompt, pick a model and aspect ratio, and render a short clip. Great for B-roll, concept shots, and quick tests.
Scripted Video
The full generator form with every render option in one place — prompt, model, aspect ratio, variations, and advanced brand and caption settings.
Templates
Pre-built ad formats like podcast, cinematic, and street interview that you customize with your own product and avatar, then render.
Story Mode
Build a multi-scene story where the outfit and overall look stay locked across every scene, then stitch the scenes into one continuous video.
Multi-Scene Builder
Build a longer video from several scenes, each with its own visual prompt, script line, and optional avatar, joined with voiceover and captions.
Screen Record
Record a live website or app into a clean MP4 with optional scripted actions, ideal for product-demo B-roll and talking-head overlays.
Create images
9Image Agent
Generate an image from a prompt, then keep chatting to refine it edit by edit, with every version saved so you can branch.
Product Staging
Drop a product photo into a styled, on-brand scene with realistic lighting by uploading the product and describing the setting.
AI Expand (Outpaint)
Extend an image beyond its edges to fit a new aspect ratio, generating believable surroundings instead of cropping the subject.
Resize & Reframe
Quickly resize or reframe an image to 9:16, 1:1, or 16:9 for different platforms while keeping the subject in frame.
AI Shadows
Add realistic, natural-looking shadows to a product cutout so it sits convincingly on a surface instead of floating.
Photo Enhance
Upscale and clean up any image — sharpen detail, cut noise, and lift resolution so it looks crisp on screen.
Background Remove
Cut the background out of any image in one click and get a clean transparent subject ready to drop into scenes.
Animate Image
Turn a still image into a short video with motion, optionally placing the subject into a described scene first.
Thumbnails
Generate eye-catching thumbnails for your videos — describe what you want or start from a frame of your clip.
Edit & assemble
5Combine Videos
Stitch multiple clips into one video — upload or pick your clips, set the order, and Krex AI concatenates them into a single export.
Timeline Editor
Arrange clips, images, and audio on a timeline for finer control — trim, sequence, and layer elements into the final cut.
Watermark Cleanup
Remove a static watermark or logo from a video so you can reuse footage cleanly in your own ads.
Before / After
Create a before/after reveal from two images — a high-converting format for product results and transformations.
Transcribe
Turn audio or video into text — caption clips, repurpose talking-head content into copy, or pull a script from existing footage.
Research & ideas
6Prompt Studio
Turn a sentence, an image, or any video URL into a rich cinematic shot-list prompt you can save and send straight into a render.
Hooks
Generate scroll-stopping opening lines for your short videos — describe your product or topic and get a batch of hooks to test.
Trend Analyzer
Paste a trending or competitor video URL and get a breakdown of its hook, pacing, and structure — then build your own version.
Competitor Analysis
Study competitor accounts and videos to extract the hooks, formats, and posting patterns that work — then outcompete with your own spin.
Winning Ads
A swipe library of proven video and static ads — browse by niche, then one-click rebuild any ad as your own with your product and avatar.
Scanner
A topic and trend discovery dashboard that will surface trending topics by region and industry to feed your content pipeline — coming soon.
Brand & avatars
5Brand kit & publishing
Lock your brand once so every render stays consistent, then connect accounts to publish.
Avatar Studio
Browse preset talking-head avatars, generate a custom one from a description, or upload your own portrait to reuse across the ad tools.
Personal Clones
Create a digital twin of yourself from a single photo, optionally linked to a cloned voice, then one-click render yourself delivering any script.
Voice Library
Pick from a catalog of natural text-to-speech voices, or clone your own from a short sample, to drive talking-head and voiceover renders.
Products
Save a product's name, URL, description, and reference images once, then reuse it across the ad tools without re-entering the details.
