"AI storyboard generator" is a crowded label hiding very different tools. Some write a script and generate video; some make pretty still frames; some are manual clipart builders with no AI at all. This roundup cuts through it: six real options in 2026, what each is genuinely best at, and where each falls short — written to help you pick, not to crown a single winner.
One note before the list: if what you actually need is a blank board to sketch on, you may not need a tool at all — we publish free storyboard template PDFs (6-panel, 9-panel, and a cinematic shot sheet) with no signup and no watermark.
Quick answer: best by use case
- Best all-rounder (storyboard → real video): FlyAIgh — script-first, consistent cast, your choice of model per shot.
- Best bundled pre-vis timeline: Katalist — clips on a timeline with voiceover + lip-sync, tuned for ad agencies.
- Best for multi-scene film production: LTX Studio — scene/shot structure and production thinking.
- Best for collaboration & sign-off: Boords — comments, review links, animatics (no real video).
- Best for classrooms: Storyboard That — manual clipart, education plans, no AI.
- Best free hand-drawing tool: Storyboarder — free, open-source, offline; no AI.
How we compared them
Four questions separate these tools more than anything else:
- Does it generate actual video, or only still frames / clipart?
- Does it write the script and break it into shots, or only arrange images?
- Does it keep characters consistent across shots?
- What does it cost, and is there a real free tier?
- What do you have to start from: one sentence, a finished script, or drawing every panel yourself?
- Can you use the result commercially, and on which plan?
The six tools, reviewed
1. FlyAIgh — best all-rounder for storyboard-to-video. FlyAIgh's Director writes a screenplay first (and pauses for your approval), assigns a consistent cast, lays out a storyboard, and compiles each shot into a video prompt you can render on your choice of model (Seedance 2.5 and 2.0, WAN 3.0, Google's Gemini Omni, Kling and more) from one account. Best for creators who want the board to become real footage with model choice. Limitation: you assemble the final cut in your own editor rather than an in-app timeline. Free tier: planning is free with no card (three new boards a day); generating images and video uses credits, and downloads need a purchase.
2. Katalist — best bundled pre-vis timeline. AI script-to-storyboard with built-in video clips, a timeline, voiceover, and lip-sync, aimed at ad agencies and filmmakers. Best for client-facing pre-vis you assemble in one place. Limitation: you don't pick the specific flagship model per shot, and there's no permanent free tier (a 7-day trial, then a paid plan). See the full FlyAIgh vs Katalist comparison.
3. LTX Studio — best for multi-scene film production. A production-structured platform with AI storyboards, scenes, and shots. Best for narrative projects that think in scenes. Limitation: both the AI storyboard feature and commercial use start at the $35/mo Standard plan (Free and Lite are personal use only), and it doesn't carry Sora 2 / Midjourney v7. See the FlyAIgh vs LTX Studio comparison.
4. Boords — best for collaboration and sign-off. A polished storyboarding tool with AI still frames, character consistency across frames, real-time comments, client review links, and animatic previews. Best when your bottleneck is team/client approval. Limitation: it does not generate video — animatics are timed slideshows of stills — and the free plan is small (5 active boards, 8 sample AI images); paid plans start at $39/mo. See the FlyAIgh vs Boords comparison.
5. Storyboard That — best for classrooms. A manual drag-and-drop clipart builder with a large asset library, purpose-built for K-12 education. Best for teaching and deterministic, repeatable boards. Limitation: no AI and no video, and free-account boards are public and non-commercial. See the FlyAIgh vs Storyboard That comparison.
6. Storyboarder — best free hand-drawing tool. A free, open-source desktop app for drawing boards by hand, with a 3D scene-posing previs helper. Best for artists who want full manual control offline. Limitation: no AI generation, and it's only intermittently maintained. See the FlyAIgh vs Storyboarder comparison.
Side-by-side comparison
| Tool | Generates video? | You start from | Character consistency | Free tier | Commercial use |
|---|---|---|---|---|---|
| FlyAIgh | Yes — you pick the model per shot | One sentence or a full script; it writes the screenplay and shot list | Yes (carried into video, across models) | Planning free (3 new boards a day), 25 sign-up credits; downloads need a purchase | Yes — you own outputs (Terms §5), subject to each model provider’s terms |
| Katalist | Yes — bundled models | A script you paste in | Yes | 7-day trial, then paid | Outputs are yours (ToS §2.7); commercial use not spelled out |
| LTX Studio | Yes | One sentence or a full script (AI Storyboards from the $35/mo Standard plan) | Yes (Elements, Standard plan) | 800 one-time credits, personal use only | From Standard ($35/mo); Free and Lite are personal use only |
| Boords | No — animatics only | A script, then AI frames per shot | Yes (stills) | 5 active boards, 8 sample AI images | Not addressed in its public terms (2021, before AI frames) |
| Storyboard That | No | Drag-and-drop clipart scenes and characters | Reuse clipart | 2 boards a week, 3 cells, watermarked, boards public | Paid plans only, by tier; raw boards in campaigns over $10k need approval |
| Storyboarder | No | Drawing every panel yourself (3D posing helper) | Draw by hand | Free / open source | Yes — the drawings are yours |
How to choose
- Do you need video, or illustrated panels? If footage, look at FlyAIgh, Katalist, or LTX Studio. If illustrated boards for review, Boords. If clipart/teaching, Storyboard That. If hand-drawn, Storyboarder.
- Do you want to pick the model per shot? That's FlyAIgh's edge — others use a fixed or bundled set.
- Is in-app assembly important? Katalist and LTX assemble in-app; FlyAIgh hands you shots to cut in your own editor.
- What's your budget? For AI on a free tier, start with FlyAIgh; for free hand-drawing, Storyboarder.
After the board: turning shots into video
A storyboard is the plan; the shots still have to be generated. These pick up where this comparison stops:
- Choosing the video model. Veo 3.1 caps every clip at eight seconds in 16:9 or 9:16, and Sora 2 Pro is the most expensive per second — see Veo 3 alternatives and Sora alternatives for what else each shot could run on, with real credit prices.
- Writing the shot prompts. How real video prompts are structured, from 381 prompts people actually ran.
- Directing performance. Do video models follow acting directions? — a frame-by-frame check of what gets executed and what gets quietly substituted.
- Budgeting for retries. Not every generation comes back usable — measured failure rates by model and content-moderation rejection rates.
Frequently Asked Questions
What is the best AI storyboard generator in 2026?
There is no single winner — it depends on what you need after the board. For generating actual video from a storyboard with a consistent cast and your choice of model, FlyAIgh is the strongest all-rounder. For a bundled pre-vis timeline with lip-sync aimed at ad agencies, Katalist is excellent. For multi-scene film-production structure, LTX Studio. For collaborative sign-off on illustrated boards, Boords. For classrooms, Storyboard That. For free hand-drawing, Storyboarder. Match the tool to the job rather than chasing one "best."
What is the best free AI storyboard generator?
FlyAIgh lets you plan a storyboard for free with no card required — concept, style, script, cast, and shot prompts — and you only spend credits when you generate actual images or video (you get 25 credits when you sign up; more come with a purchase). New boards on a free account are capped at three a day. Storyboarder is completely free and open-source but is a hand-drawing tool with no AI. Storyboard That and Boords have free tiers but with tight caps. For AI-assisted planning at no cost, FlyAIgh’s Director is the most capable starting point.
Which AI storyboard tools actually generate video?
Of this list, FlyAIgh, Katalist, and LTX Studio generate actual video. Boords produces AI still frames and timed animatics (slideshows), not generated video. Storyboard That (manual clipart) and Storyboarder (hand-drawing) generate no video at all. If your goal is footage rather than illustrated panels, focus on the three that render video.
Which tool is best for keeping characters consistent across shots?
FlyAIgh, Katalist, LTX Studio and Boords all offer character consistency. FlyAIgh, Katalist and LTX Studio carry it into generated video (on LTX it is the Elements feature, from the Standard plan); Boords keeps it across still frames. FlyAIgh’s approach binds identity references plus a persona to a reusable Character that follows the cast across shots and across different models, which is the most flexible for multi-model video work.
Can I use AI storyboards commercially?
It depends on the tool and the plan. FlyAIgh: you own what you generate and may use it commercially under its Terms of Service (section 5), subject to each model provider’s terms; downloading needs a purchase. LTX Studio: only from the Standard plan ($35/mo); Free and Lite are personal use only. Storyboard That: free-account boards are non-commercial; paid plans allow commercial use by tier, and using a raw board in a campaign over $10,000 needs approval. Katalist: its terms say you keep the rights to what you generate but do not spell out commercial use. Boords: its public terms (last updated 2021, before its AI frames) do not address commercial use of AI images. Storyboarder: you draw the frames yourself, so they are yours. Check the current terms before client work.
Which AI storyboard generator is easiest to start with?
The ones that start from a sentence ask the least of you. FlyAIgh and LTX Studio both take one sentence or a full script and break it into scenes and shots for you, with no shot-by-shot data entry; on LTX the AI storyboard feature needs the Standard plan. Katalist and Boords start from a script you paste in. Storyboard That is quick to learn but every panel is built by hand from a clipart library, and Storyboarder expects you to draw.
