AI Tool Pricing Index - September 2026

The median paid entry point in the AITokenHub Price Index is $18/mo across 201 subscription tools, verified 2026-09-14. Individual plans cluster between $8 and $30 per month: that band covers the entry tiers of most established products, while pro tiers typically land between $20 and $60. Team and enterprise seats push higher, usually 1.5x to 2x the individual price per user.

Category economics differ more than most buyers expect. The lowest median entry points among larger categories are AI Image at $10/mo, AI Audio at $11.99/mo, AI Presentations at $12/mo. The highest are AI Email at $30/mo, AI Customer Support at $115/mo. Budgeting by category median beats budgeting by the first price you see on a vendor homepage, because landing pages anchor on pro tiers.

15 of the 240 tools in the index are completely free or open source, and the strongest rated include OpenEvidence, Stable Diffusion, NotebookLM, Flux, Llama, Continue. Genuinely free means the core workflow works without a card: a free product, an open-source project you self-host, or a vendor free tier with no trial clock attached.

Beyond those, 168 tools run freemium models with free tiers good enough for light personal use. The distinction matters in practice: freemium free tiers usually cap volume or features, so they break under production workloads. Our free AI tools list keeps the two groups separate so a zero-cost shortlist never collapses into a paywall mid-task.

Usage-based rates in the index start as low as DeepSeek at $0.14/M input tokens, OpenAI Realtime API at $32/1M tokens, Perplexity API at $1/1M tokens / Sonar Pro $3-$15/1M, GLM-5.3-Flash at $0.03/1M / 50% launch discount. Per-token pricing shifts cost from a fixed subscription to a variable bill, which favors spiky low-volume usage and penalizes steady heavy usage.

Compare API rates against subscriptions with your own volume math: at typical chat workloads of 10 to 30 million tokens per month, per-token bills often exceed a flat $20 subscription, while a prototype doing 1 million tokens per month costs cents. Vendors also price input and output tokens separately, so read the full rate table before extrapolating from a single number.

Legora carries the highest starting subscription in the index at $3000/mo as of 2026-09-14. Premium pricing at this level usually buys enterprise controls, priority capacity and support SLAs rather than raw capability alone, which is why the same vendors often run cheaper individual tiers alongside.

A high entry price does not automatically mean poor value: our editorial assessment scores Legora at 4/5 for value for money. Judge cost against the workload it replaces. For most individuals the $8 to $30 per month band covers every category in this index, and upgrading past it only makes sense when usage limits, not features, are the constraint.

The index is a build-time data asset, not a scraped widget. Every price in the table comes from the AITokenHub editorial dataset covering 240 tools, where pricing strings are verified against vendor pages during scheduled data maintenance and normalized into a starting entry point: the lowest publicly listed monthly cost, or the per-million-token rate for usage-based products.

Verification runs on a rolling cycle, and any vendor price change triggers a data fix followed by a full site rebuild, so every tool page, comparison and this index share one source of truth. That is why a price here can differ from an older blog post elsewhere: we date every verification (2026-09-14 as of this build) and refresh the whole table together instead of leaving stale numbers scattered across pages.
