Features

What you can do

Text to sound effect

Describe the sound in plain words — "heavy wooden door creaking open", "laser blast with metallic tail" — and the AI generates it. No sound libraries to dig through, no recording gear. Try it now.

Free and no sign-up to start

Generate your first sound effects without creating an account. Every Sunra account also gets free daily credits — no credit card, no watermark on what you make.

Sound effects for your video

Already have a clip that needs audio? Generate matching SFX — footsteps, impacts, ambience, whooshes — and layer them onto your footage right inside Sunra's video tools.

Studio-ready, commercial-safe output

Export clean audio you can drop straight into a timeline. Generated effects are yours to use in monetized videos, games, and client work — no attribution required.

Endless variations on one idea

Re-roll the same prompt to get a different take, or tweak the wording to shift tone — softer, punchier, longer tail. Audition options fast instead of settling for the first hit in a stock pack.

Runs in your browser

No plugin, no desktop app, no install. Type, generate, and download from any device with a browser — Mac, Windows, Chromebook, or tablet.

How to use

Describe the sound

Type what you want to hear — the object, the action, the mood. The more specific the description, the closer the result.

Generate and audition

The AI returns a sound effect in seconds. Not quite right? Re-generate or adjust your wording to get a different take.

Download and use

Download the clip and drop it into your video editor, game engine, or podcast — royalty-free and ready to publish.

Who it's for

Use cases

Game developers

Prototype and ship custom SFX — UI clicks, pickups, hits, spells — without licensing a sound pack or hiring a foley artist for every iteration.

Video editors & YouTubers

Fill gaps in your edit with exactly the whoosh, impact, or ambience a moment needs, instead of scrubbing a stock library for a near-match.

Podcasters & audio producers

Add transitions, stingers, and background textures generated to fit your script — all royalty-free and safe to monetize.

Motion & social creators

Punch up transitions and reveals in short-form video with snappy, on-brand sound effects that match the cut.

The quality jumped overnight

We switched our product video pipeline to Sunra last month. Kling 3.0 with native audio is genuinely usable for social ads now. Our team ships 30+ variations a week without touching After Effects.

Finally a tool my whole team can use

I'm technical, my co-founder isn't. She hops into Sunra, types a prompt, and gets a polished video in minutes. Canvas is the killer feature — we brainstorm visually and export straight to pitch decks.

Multi-language campaigns overnight

We localized a campaign into seven languages in a single afternoon — dubbing, subtitle alignment, even regional visuals. That's a month of work in traditional production.

Kling 3.0 outputs are production-ready

I stopped color-grading AI videos after I tried Sunra's Kling. The lighting and motion are consistent enough that I drop clips straight into Premiere and publish.

I shipped a short film in a weekend

Four-minute narrative piece, start to finish, Saturday afternoon to Sunday night. Would have been a six-week indie project a year ago. Still can't believe it.

Restaurant content that sells food

We run six restaurants. Sunra makes mouth-watering dish reels in our brand style. Uber Eats conversions from social jumped 38% after we started using generated content.
