Generate thumbnails from scratch, then refine by chatting
Tailsy is an AI thumbnail creator built around a chat. Describe the video — topic, title, and audience — and it generates scroll-stopping thumbnail concepts from a simple prompt. There is nothing to design and no prompting skills to learn.
From there you direct it like an editor. Ask for changes in plain language — brighter, closer crop, a different expression, a new title, swap the background, remove an element — and each request updates the thumbnail instead of starting over.
- Generate original thumbnails from a video title or topic
- Request edits in plain language, with no redo from scratch
- Train your face and star in your own thumbnails
- Attach references, add inspiration, and match a style
Every tool a creator needs, in one place
Tailsy gives you a full toolbox — styles, inspiration, attachments, character training, and micro-editing tools — so you are never locked into one look. Use it for the whole thumbnail process, not just quick concepts: generate a thumbnail from scratch, test several directions, drop in references, characters, and styles, then request edits in plain language until it is ready to publish.
Because everything happens in one chat, you can move from a rough idea to a finished, on-brand thumbnail — and keep a consistent face and style across an entire series.
- Compare multiple directions before committing
- Keep a consistent character and style across videos
- Use templates and inspiration for proven layouts

Frequently asked questions
Can the AI thumbnail generator create thumbnails from scratch?
Yes. Describe the video and Tailsy generates original thumbnail concepts from a text prompt — no template or design tool required.
Can I edit a thumbnail after it is generated?
Yes. Ask for changes in plain language, such as brighter, closer crop, a new title, or a different background, and Tailsy updates the thumbnail instead of starting over.
Can I keep the same character across thumbnails?
Yes. Save a character and reuse it so the same face stays consistent across your videos, and apply a saved style to keep a consistent look.
Do I need design or prompting skills?
No. Tailsy is built for creators with no design skills. A video title or a few simple instructions is enough to generate high-quality thumbnails, and you refine them by chatting.
Can I put my own face in the thumbnail?
Yes. Train a character on your face and star in your own thumbnails, with the same face kept consistent across videos.
