Upgrades take effect immediately. You are charged only the prorated difference for the remaining days in your billing cycle. Downgrades take effect at the end of your current billing cycle. You keep your current plan's features until then, and no partial refund is issued for unused days on the higher plan. To change your plan, go to Account > Manage Billing, which opens the Stripe billing portal where you can switch plans, update payment methods, or cancel.

We accept all major credit cards (Visa, Mastercard, American Express) through our secure payment processor, Stripe.

Each paid plan has a specific top-up option available when your monthly characters are used up: Starter gets +100,000 for $3, Pro gets +300,000 for $7, and Studio gets +1,000,000 for $20. Top-up characters are consumed only after your base allowance is exhausted. Free users can upgrade to a paid plan for more characters.

Top-ups are one-time character purchases available to all paid plan subscribers when their monthly allocation is depleted. Each plan has one specific top-up: Starter gets +100,000 for $3, Pro gets +300,000 for $7, and Studio gets +1,000,000 for $20. Credits are consumed only after your base plan allowance is exhausted. The purchase button is greyed out until your monthly characters are fully used. Top-ups do not replace subscriptions.

The free plan supports streaming and playback only. To download generated audio files, upgrade to any paid plan (Starter, Pro, or Studio).

Voices are grouped into four tiers: Free voices (available on all plans), Starter voices (available on Starter, Pro, and Studio plans), Pro voices (select expressive character voices available on Pro and Studio plans), and Studio voices (full premium voice library available on Studio plan only). Cloned voices are also available on the Studio plan.

Voice cloning is available on the Studio plan ($15/mo) only. Upload an audio sample (15-30 seconds of clear speech) and your cloned voice is ready within seconds for use in TTS. Studio accounts get 3 voice slots total (shared between cloned and designed voices), and you can delete or swap any voice at any time. You can also rename a clone any time from the Account page; the rename syncs to the Inworld dashboard. You must have legal rights and consent to clone any voice you submit.

Yes! Free users can preview 3 Studio voices (Hunter, Sarah, and Benedict) up to 3 times at no cost. Just select one from the Studio Previews section in the voice dropdown and click Preview. After your 3 previews, upgrade to Studio ($15/mo) for unlimited access to all Studio voices.

No separate trial. The Free plan is 2,000 characters per month, forever, with no credit card required. You also get 3 free previews of Studio voices (Hunter, Sarah, and Benedict) before deciding to upgrade.

You can adjust speed (0.5x to 2x), pitch (Very Low to Very High), volume (25% to 100%), sample rate (16kHz to 48kHz), and output format (MP3 or WAV). You can also choose a delivery style, add audio markup emotion tags and non-verbal sound effects, and filter voices by language, region, and gender.

Audio markups let you add emotion and delivery tags like [happy], [whisper], [excited], and [professional] to your text. Sound effects let you add non-verbal sounds like [laugh], [sigh], [gasp], [cough], and [breath]. Audio markups are available on Pro and Studio plans, while sound effects are available on all plans. Tags are not counted toward your character usage.

Voice Design lets you create a custom AI voice from a text description. Describe the voice you want (age, gender, tone, accent, personality) and the AI generates a unique voice for you. Voice Design is available on the Studio plan and shares the same 3-slot pool with voice cloning. You can delete or swap any designed voice at any time.

When generating audio on Pro or Studio plans, check the "Include subtitles" option. After generation, an SRT download button appears next to the audio download button. The SRT file contains word-level timestamps that sync with your audio, perfect for adding captions to videos.

Speech to Text lets you upload an audio file (WAV, MP3, WEBM, or M4A) and get a text transcript. Available on Starter plans and above. Daily limits vary by plan. You can edit the transcript and even use it directly as TTS input.

We support MP3 (compressed, smaller file size) and WAV (uncompressed, higher quality). Both are widely compatible with video editing software, media players, and other audio tools.

It varies by plan: Free (2,000), Starter (5,000), Pro (10,000), and Studio (20,000) characters per request. For longer texts, you can split them into multiple requests.

Most audio is generated within a few seconds. Longer texts may take slightly more time, but typically no more than 10-15 seconds for maximum-length requests.

You can also delete or swap them yourself at any time from the Create page (up to 3 voices total per account, cloned and designed combined).
