Free: enough to try

Start here. Every app below has a free plan, with limits that are not published as exact numbers.

More usage than Free without the full price. Good if you only hit limits sometimes.

About $20: daily use

The sweet spot for people who use AI most days for writing, study, research or work.

Price confidence: Confirmed on the official page. Checked 2026-10-16. source 1, source 2

  • OpenAI's pricing page did not show prices when we read it, so the $20 comes from OpenAI's help pages and launch post.

Claude Pro$20/mo

Everything in Free with at least 5x more usage per 5-hour session, plus Claude Code, research mode and Opus.

Who it's for: People who write, study or code a lot and want more room than Free, plus the top Opus model. (our editorial view)

Models: Opus, Sonnet, Haiku; Fable via usage credits

Usage limits: 'At least 5x' Free per 5-hour session, plus weekly limits.

Annual or other billing: $17/month billed annually ($200 up front); $20 if billed monthly.

Annual or other billing: $199.99 a year

Price confidence: Confirmed on the official page. Checked 2026-10-16. source 1, source 2

Meta One Premium$19.99/mo

Higher tier of the same bundle with more AI generation.

Who it's for: Heavy social-media users who want more Meta AI image and video creation. This is a social bundle, not a general chatbot plan. (our editorial view)

Models: As Core

Usage limits: Not published.

Price confidence: From press or an older official post. Checked 2026-10-16. source 1

Confirm at checkout. We could not read this price on the current official page, so it comes from press or an older official post.

Who it's for: People who research all day and want cited answers and a choice of models. (our editorial view)

Models: Choose among top models

Usage limits: Higher than Free; no numbers.

Annual or other billing: $17/month when billed annually. Monthly-billed price not shown on the page we could read; a third-party site says $20 (unconfirmed).

Price confidence: Annual-billing price only. Checked 2026-10-16. source 1

Confirm at checkout. The official page only shows the price when billed annually, so the monthly-billed price is not confirmed.

  • Perplexity's pricing page prints only the annual rate. Third-party price trackers list $20 a month (including on the Apple App Store), which we could not confirm on Perplexity's own page.

$100 to $200 and up: you hit limits every day

Only worth it if the $20 plan keeps running out. These mostly add usage, not smarter answers.
