The blog.
Deep dives, comparisons, and roundups on the AI tools worth paying for. Only what we'd actually buy — no SEO sludge, no influencer demos.
Best AI search engine: one question, three engines
The best AI search engines, tested with one identical question. All three agreed on the facts. One cited EUR-Lex, another a consultancy blog and YouTube.
ChatGPT vs Gemini: the free tier decides this one
ChatGPT vs Gemini, both tested on free accounts. One hands a non-paying user its advanced reasoning model; the other will not let you pick a model at all.
Claude Max plan: the 5x is per session, not per month
The Claude Max plan costs $100 or $200 a month. The multiplier everyone quotes describes a five-hour window, and the limit that actually stops you is weekly.
Perplexity pricing: $20 a month, or $17, on the same site
Perplexity pricing is $0, $20 or $200 a month. Its own plan pages show two different headline numbers, and the Enterprise tab quietly switches billing basis.
ChatGPT vs Claude: one writes, one does everything else
ChatGPT vs Claude, from a paid Claude account and a year on ChatGPT free. Both $20, but the free tiers differ far more — and only one generates images.
Claude vs ChatGPT vs Gemini: they don't all cost $20
Claude vs ChatGPT vs Gemini, after reviewing all three separately. Two cost $20, one is a storage plan — and the free tiers differ far more than the paid.
Google Gemini review: the best free tier, sold as storage
A Google Gemini review from the free tier: four models including 3.1 Pro handed over for nothing, then paid tiers that are really 400GB, 5TB and 20TB of Drive.
Claude AI review: brilliant at words, strange about limits
A Claude AI review from a paying Max account. My $100 Max 5x plan invoiced at $111.11, three usage meters run at once, and overflow is billed at API rates.
Best AI voice generator: what an hour of audio really costs
ElevenLabs wins on voice and costs $10.91 an hour. We normalised six AI voice generators plus open-source to one unit: the cost of an hour you can publish.
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.
Best AI voice cloning: which tool actually sounds like you?
ElevenLabs is the best AI voice cloning tool overall, but the right pick depends on whether you're cloning your own voice, building an app, or want it free.
Best ElevenLabs alternatives: which one replaces it?
The best ElevenLabs alternative depends on why you're leaving. I lined up Murf, Descript, Cartesia and 4 more against the one job each actually wins.
