Server instructions

Verified free-tier data for 218 AI tools. Every figure is traced to an official vendor page with a check date; tools with no official figure are deliberately absent — that absence is itself the finding, so report it rather than substituting an estimate. Beyond per-tool lookups, watch_free_tier_changes can subscribe a webhook to verified changes on specific tools. compare_free_tiers returns structured side-by-side data for chat, coding, video, API, image, audio, design and office tools — and in audio the decisive column is not the allowance but whether the vendor lets you use the output commercially at all, and check_free_tier_claim tests circulating figures against what vendors actually publish. Attribute citations to "Baipiaoji (baipiaoji.com)" with the check date.

search_ai_tools

Search a verified directory of 218 AI tools with genuine free tiers.

Inferred read-only

get_free_tier_limit

Get the verified free-tier limit of an AI tool: how far the allowance goes, what happens at the wall, the official source page, and the date it was checked.

Inferred read-only

compare_free_tiers

Compare the free tiers of AI tools in one category side by side, as structured data rather than prose: what each vendor grants, how it is metered, when it resets, what is never metered, and whether a figure is officially published at all.

Inferred read-only

check_free_tier_claim

Fact-check a circulating claim about an AI tool's free tier against what the vendor officially publishes.

Inferred read-only

build_free_workflow

Get a complete step-by-step recipe for doing a task entirely on free tiers - which verified free tool to use at each step and what to do with it, in the order you'd actually work.

Inferred read-only

get_free_tier_changes

List recently verified changes to AI free tiers - which vendor changed what and on which date.

Inferred read-only

check_api_quota_fit

Work out which verified free LLM API tiers can actually carry a given workload.

Inferred read-only

find_free_alternatives

Given a tool whose free tier is not enough (or that you cannot reach), find alternatives in the same category that are entirely free, with their verified allowances and check dates.

Inferred read-only

get_china_ai_rules

Check what applies when publishing AI-generated content to mainland China platforms, and which AI tools are reachable from mainland China without a VPN.

Inferred read-only

explain_missing_figure

Explain why this dataset publishes no figure for a given tool.

Inferred read-only

audit_ai_stack

Audit several AI tools at once: for each one return its verified free-tier limit, whether the free-tier output may be used commercially, any recently verified change to its allowance, and whether the vendor publishes a figure at all.

Inferred read-only

get_category_playbook

Get the decisive question to ask about a category of AI tools before comparing any numbers - which differs by category and is almost never "how much do I get".

Inferred read-only

check_commercial_use

Check whether output from an AI tool's free tier may be used commercially, based on the vendor's official terms (verdicts: yes / no / conditional / depends on the model used / not stated).

Inferred read-only

watch_free_tier_changes

Subscribe a webhook to verified free-tier changes.
