search_ai_tools

Search the verified directory of AI tools with genuine free tiers (every result carries directory_size, so no count is hard-coded here). Filter by category (chat/coding/image/video/audio/design/search…

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. Absence of a tool means no officially verif…

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 …

check_free_tier_claim

Fact-check a circulating claim about an AI tool's free tier against what the vendor officially publishes. Returns what the official pages actually say and whether the widely-quoted figure has any offi…

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. Covers slide decks, …

get_free_tier_changes

List recently verified changes to AI free tiers - which vendor changed what and on which date. Vendors do not announce when they cut, rename or restructure a free tier; this log is accumulated from da…

check_api_quota_fit

Work out which verified free LLM API tiers can actually carry a given workload. Give the expected calls per day and average tokens per call; this divides the officially published limits by that load a…

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. Use this when a us…

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. Two independent gates matter there: the vendor'…

explain_missing_figure

Explain why this dataset publishes no figure for a given tool. Absence here is a finding, not an oversight: for each listed tool the reason is recorded - the vendor states outright it publishes no num…

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 …

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". Video generation turns on what the water…

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). Not legal a…

watch_free_tier_changes

Subscribe a webhook to verified free-tier changes. When a watched tool's allowance, wall or commercial terms change (verified daily against official vendor pages), the webhook receives a JSON payload …

monitor_new_agents

List source-backed AI agents, MCP servers and agent platforms tracked by Baipiaoji (hand-curated records plus listings from the official MCP registry). Filter by audience (who it is for), category, st…

get_agent

Return a single agent-watch record by slug (or exact name): description, audiences, capabilities, transport, pricing shape, official source and repository URLs, the official page’s own title/descripti…

site-journeys

Static discovery map of BPJ tools, directories, developer and vendor pages with usage conditions and next steps. These are page links, not executable MCP tools or verified conversion outcomes.

baipiaoji://site-journeys
verified-free-tier-limits

Every free-tier ceiling we could trace to an official vendor page, with the quota, what happens at the wall, the official source and the date it was checked. Tools whose figures cannot be officially v…

baipiaoji://limits
ai-tool-directory

The whole verified directory: category, tags, what is free, official URL, verified-limit summary and commercial-use verdict for every listed AI tool.

baipiaoji://directory
structured-quota-comparison

Machine-comparable free-tier data for chat, coding, video and API tools: what is metered, when it resets, what is never metered, and whether the vendor publishes a figure at all. Structured from the v…

baipiaoji://quotas
free-tier-myth-checks

Widely circulated claims about AI free tiers checked one by one against what vendors actually publish — including which popular figures have no official source at all.

baipiaoji://myths
free-workflows

Complete step sequences for doing common tasks entirely on free tiers, each step naming the verified tool and what to do with it, plus zero-budget money playbooks that state who they suit, why most pe…

baipiaoji://workflows
free-tier-changelog

Dated log of verified changes to AI free tiers — vendors do not announce these, so it is accumulated from daily re-checks against official pages.

baipiaoji://changes
refusal-list

Tools for which this dataset deliberately publishes no figure, each with the specific reason — vendor refuses to publish, official pages contradict each other, terms say it changes at any time, or no …

baipiaoji://no-source
category-rules-and-wall-taxonomy

The decisive question to ask in each category before comparing numbers, plus the six or seven structurally different shapes a free-tier wall takes, each with verified examples. This is the layer that …

baipiaoji://insights
full-dataset-text

The entire verified dataset in one plain-text file: every limit and commercial-use verdict, bilingual, with sources, check dates and the verification method.

baipiaoji://dataset
agent-watch

Source-backed agent and MCP discovery records with first-seen, last-verified, lifecycle status, transport, capabilities and evidence level.

audit-my-ai-stack

Check the AI tools you rely on against verified free-tier limits and commercial-use terms: where each wall actually is, which figures the vendors never publish, and what breaks if you publish the outp…

pick-a-free-tier

Compare verified free tiers in one category against what you actually need, using officially sourced figures rather than the numbers circulating in guides.

fact-check-a-free-tier-claim

Take a specific claim about an AI tool's free tier and check it against what the vendor officially publishes — including whether the figure has any official source at all.

watch-my-free-tiers

Set up webhook alerts for the AI tools you depend on: when a verified free-tier allowance or commercial-use term changes, your webhook hears about it the same day, with the official source attached.
