Free AI Script Generator

Most video scripts die in the first three seconds. Viewers decide almost instantly whether to keep watching, which is why professional scriptwriters obsess over the hook before anything else. This generator is trained on that structure: every script opens with an attention-grabbing first line, builds tension through the middle, and lands on a takeaway or call to action.

Unlike generic AI chat tools, the output here is pure spoken-word narration — no stage directions, scene labels, or markdown to clean up. The length is calibrated to real narration speed (about 2.5 words per second), so a "60-second" script actually runs 60 seconds when you record it. Pick your platform and the structure adapts: Shorts, TikToks, and Reels front-load the payoff, while YouTube scripts build a fuller narrative arc.

When your script is ready, you can copy it, download it, or click "Turn Into a Video" to have Broller match every line with stock footage, generate an AI voiceover, and export a finished video.

What a generated script looks like

Every script follows the same load-bearing structure regardless of topic: a hook in the first line, a promise of what the viewer will get, escalating beats through the middle, and a payoff or call to action at the end. Here is the opening of a real output for the topic "why cheap running shoes might be better for you", 60 seconds, engaging tone:

"Runners spending $200 on shoes are getting injured just as often as runners spending $40 — and a 2015 review of 63 studies couldn't find a connection between price and protection. Here's what actually matters when your foot hits the ground…" — notice there is no "Hey guys, welcome back". The script starts mid-claim, because the first three seconds decide whether the video gets watched at all.

How to write a topic prompt that gets a great script

The single biggest quality lever is the topic you type in. The generator amplifies whatever angle you give it, so a sharper input produces a sharper script. Four patterns consistently outperform a plain topic:

• State a tension, not a subject — "why most morning routines fail by day 4" beats "morning routine tips".
• Name the audience — "explaining index funds to someone who has never invested" changes vocabulary, examples, and pacing.
• Give one concrete fact you want included — the generator builds the narrative around it instead of inventing generic filler.
• Specify the format — "a myth-busting video", "a story-driven video", or "a listicle" each produce visibly different structures.
