Jasper sells brand-controlled content production: Pro at $69 a month billed monthly or $59 a month billed yearly with one seat included and a 7-day trial, and a Business tier that is quoted rather than priced, with a 12-month commitment as its minimum. Writesonic sells content plus measurement: Starter $79, Basic $199 and Growth $399 a month billed annually, Enterprise custom, with the pricing page led by tracking how a brand appears in ChatGPT, Gemini and Google AI Overviews. If the job is producing on-brand marketing copy, these two genuinely compete. If the job is working out whether AI recommends you, only one of them is selling that.
ChatGPT is a general assistant with a free tier, Go at $8, Plus at $20 and Pro from $100 a month, gating specific models so GPT-6.1 Sol and GPT-6 Astra start at Plus, alongside expanded deep research, memory and Codex. Perplexity is a search-and-answer tool: free for limited daily use with citations in every answer, Pro at $20 for deep research, top-model access and 4,000 bonus credits, and Max at $200 for expert-level research, frontier models and 10,000 monthly credits. ChatGPT meters plan limits and context windows; Perplexity meters credits and usage multipliers.
OpenAI sells ChatGPT as Free, Go, Plus at $20 a month and Pro at $100, $200 or $500 a month, with usage allowances rather than feature gates separating the paid rungs. Google sells Gemini as Free at $0 with a Google account, AI Plus at $4.99, AI Pro at $19.99 and AI Ultra from $99.99 with a $199.99 tier at twenty times the Pro limits, bundling storage from 15 GB to 5 TB plus Flow credits and video perks. The main tiers differ by one cent, so the decision is about the bundle: a research-and-coding subscription on one side, a Google services package on the other.
OpenAI sells ChatGPT in four consumer steps: Free, Go at $8 a month, Plus at $20 a month and Pro at $200 a month. Anthropic sells Claude in three: Free, Pro at $17 a month with an annual subscription ($200 paid up front) or $20 billed monthly, and Max from $100 a month at 5x or 20x Pro usage. Both mainstream tiers include a coding agent — Codex in ChatGPT Plus, Claude Code in Claude Pro — and both free tiers cover everyday chat. Pick ChatGPT for the cheaper entry tier and the widest model range; pick Claude for document-heavy work and a coding agent that starts one tier lower.
Gemini charges $0 for its free app, $19.99 per month for Google AI Pro and from $99.99 per month for Google AI Ultra, with a $199.99 higher-usage tier. Perplexity charges $0 for its free tier, $20 per month for Pro and $200 per month for Max, with Enterprise Pro from $40 per seat per month. The paid entry points differ by a cent; the differences are in what each bundle carries — Google's storage and app integrations against Perplexity's research credits and frontier-model access.
The paid tiers land within a few dollars of each other: Claude Pro is $17 a month with an annual subscription discount ($200 billed up front) or $20 billed monthly, while Google AI Pro, which carries Gemini, is $19.99 a month or $199.99 a year. Above that they diverge: Claude Max starts at $100 a month with 5x or 20x Pro usage, and Google AI Ultra is $99.99 a month, billed monthly only, with up to 20x Gemini access, Gemini Agent and Deep Think. What you actually buy differs more than the price: Claude's paid tiers include Claude Code and the Claude apps for Chrome and Microsoft 365, while Google's bundle includes Gemini inside Gmail, Docs and Sheets, 5 TB of storage on Pro and 20 TB on Ultra, and YouTube Premium.
