  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fireflies.ai

  • Video recording limits by tier: Free tier has 2 hours, Pro tier 2 hours, Business tier 3 hours, Enterprise tier 4 hours
  • Storage quotas on Free and Pro tiers: Free tier limited to 400 minutes per team, Pro tier limited to 8,000 minutes per seat
  • AI credits allocation varies by tier, with lower tiers receiving limited credits for advanced AI features

Sonix

  • Monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • Unused hours do not accumulate into a meaningful reserve, so an irregular workload of a heavy month followed by a quiet one pays overage in the first and wastes allowance in the second.
  • There is no human correction tier at self-service prices, so anyone with an accessibility or legal accuracy obligation has to add a separate supplier or a member of staff to the workflow.
  • The cited 99 percent accuracy is a best-case figure on clean single-speaker audio, and overlapping speakers, strong accents, technical vocabulary and room noise degrade it enough that editing time, not transcription cost, becomes the real expense.
  • Storage is capped per plan at 25GB to 100GB, and video files consume it fast, so long-running teams end up deleting source media or upgrading a tier for storage they do not otherwise need.

Source
Sonix: What does Sonix cost per hour?

$10 an hour on pay-as-you-go, and $10 an hour for any usage beyond the monthly allowance on every subscription tier. That overage rate is published, which is unusual in this market.

Fireflies.ai: What are Fireflies.ai's paid plan prices?

Fireflies offers three paid tiers: Pro at $10/seat/month (billed annually, $18/month if monthly), Business at $19/seat/month (billed annually, $29/month if monthly), and Enterprise at $39/seat/month (annual billing only).

Source
Sonix: Is there human transcription?

No. Sonix is automated transcription plus an editor for you to correct. If you need a contracted accuracy level, this is the wrong category of product.

The free plan includes 400 minutes of storage per team. Pro includes 8,000 minutes per seat. Business and Enterprise plans offer unlimited storage.

Source
Sonix: How accurate is it really?

The 99 percent claim assumes clean, single-speaker, standard-accent audio. Multi-speaker recordings with background noise land noticeably lower, and the cost shows up as your editing time.
