ElevenLabs sound effects: four clips for 40 credits, not 200
Seven prompts through ElevenLabs sound effects: a door, a rain loop, a 90 BPM drum loop, a spoken line. What each cost, and where the pricing page is wrong.
Suno alternatives: the one I actually tested, and eight I didn't
Every Suno alternatives list claims it tested everything. This one tested one rival properly, labels the rest, and fixes two entries the others get wrong.
CapCut auto captions: Pro in the editor, still free on one page
I tested CapCut auto captions on a free account. The editor now locks export behind Pro, but CapCut's AI Captions page exported free, with 2.7% of words wrong.
CapCut pricing: there is no single price, and CapCut says so
CapCut publishes $19.99 a month on one page and says it has no fixed global price on another. Here is what the upgrade screen showed, and how to find yours.
CapCut review: free 1080p exports, until 512MB stops you
I put a 35-minute panel through CapCut's AI clipping and exported all 8 clips. Watermark-free 1080p on the free plan, but the cloud ceiling bites at clip four.
HeyGen pricing: what the credits really cost
HeyGen starts at $29/mo, but credits decide your real cost: 600 credits is 30 min of premium avatar or 200 on the cheaper engine. Here's the full breakdown.
HeyGen video translation: one free minute, one changed meaning
I ran a 55-second talk through HeyGen video translation on the free plan. The Spanish was mostly right, ran 2.5 seconds short, and used my only free video.
Best TTS API: the price spread is 40x, and nobody says so
Cartesia for agents, ElevenLabs for quality, Google for cheap. Eight TTS APIs normalised to cost per million characters: the range is $4 to $166.
Cartesia pricing: the $5 plan goes further than it looks
Cartesia pricing sells credits, not minutes. With overages on, the $5 Pro plan beats the $49 one right up to 777K credits a month. The real per-unit math.
ElevenLabs voice changer: I gave one reading three voices
I ran a 16-second human reading through ElevenLabs' voice changer as three voices. What it kept, what it cost (266 credits), and what noise removal did.
Grammarly humanizer: I tested it, and it rewrote my facts
I ran three Claude texts through Grammarly's free humanizer and Humanizer agent, then two AI detectors. What it changed, what it scored, the limits.
QuillBot humanizer: free, 100 words at a time, and it broke my logic
I ran a Claude essay through QuillBot's free AI humanizer and its own detector. The 100-word cap, the daily limit, what it changed, and an 11% that hid a 45%.
