Avis Sondo AI (2026) : jetons, plaintes sur la qualité et remboursements — ce que disent vraiment les avis

What Sondo is

Sondo is a mobile-first app (App Store, Google Play) launched in April 2025. You upload or generate a track, describe the visuals, and the app returns a beat-matched video. Its store listings claim more than 10 million users and 15 million generated videos, which makes it the most widely used product in the category and the natural benchmark for everything else.

How Sondo's credit pricing works

Sondo sells credits through weekly or yearly subscriptions rather than selling videos (sondo.ai/subscribe). Video costs about 10 credits a second in SD and 20 in HD, so a 3-minute video comes to roughly 1,834–1,953 credits. Earlier third-party reviews quoted other pack sizes and a flat ~1,500 credits per video (YouTube: "They advertise 10 credits but it costs 1,500"); the figures below are Sondo's own, checked on 29 September 2026.

The headline prices are reasonable; the friction is elsewhere. The entry plan's 800 weekly credits can't finish one 3-minute video, the plans renew weekly or yearly rather than monthly, and reviewers say fixing a result meant paying for another generation. Watermark removal needs a subscription or a $14.99 one-off purchase.

What users complain about

Across Trustpilot (1.4 / 5, 75 reviews) and the app stores, the same four themes repeat:

• Output ignores the brief. Characters change between shots, a male voice sings a female part, prompts are only loosely followed.
• Paying to fix the tool's mistakes. One reviewer summarises it as "pay to generate, discover the defects, pay again to repair them"; another notes that "each tweak costs another 1,500 credits".
• Refunds. Reviewers report being told by Apple they were not eligible for a refund of their purchase and getting no reply from support; no company responses appear on the Trustpilot page as of this writing. (Sondo's own policy refunds credits for failed generations, but not for tasks you cancel.)
• Cancellation. Several reviews describe continued billing after cancelling, in one case months after deleting the account.

Nothing is ever right the first time — each tweak costs another 1,500 credits.

To be fair to Sondo: a 1.4 score on 75 reviews is a small, self-selected sample against millions of installs, and app-store refunds are administered by Apple and Google, not by the developer. But the complaints are consistent with the pricing design — when a video is a single opaque purchase, every defect becomes a billing dispute.

What to check before you buy credits on any AI music-video app

1. Is the cost of a whole video shown before generation, in currency, not just credits?
2. Can you regenerate one scene rather than the whole video?
3. Are failed or moderated generations refunded automatically?
4. Do you keep the same character across shots (a reference photo, not luck)?
5. Can you cancel from inside the product, and does the terms page say what happens to unused credits?

How HeyBop answers the same complaints

HeyBop was built after reading these reviews, so the trade-offs are deliberate: every button shows its price in credits before you click; a full 3-minute video is with its credit quote shown before generating, with costs based on length and quality (≈ 870–1,230 and 1,290–1,830 credits; the low end is with the usual chorus reprises, how credits work); any scene can be rewritten and regenerated alone for the price of one clip; failed or moderated generations are refunded to your balance automatically; generation starts after payment; and a photo of you keeps the same person in every shot. Payments run through Stripe, cancellation is one click in the billing page, and unused pack credits never expire (pricing).
