Tools 16 found in our last check

• 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/office/writing/api/agent), fully-free flag, works-in-mainland-China flag, or k…

• 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 verifiable number exists — this dataset publishes no unsourced figures.

• 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. Categories: chat (where the wall is - on…

• 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 official source at all - many do not. Use this when a user cites a specific number…

• 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, video editing, AI video generation, papers and literature, API-based developmen…

• 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 daily re-checks against official pages. Use this for "did anything change recentl…

• 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 and reports which providers stay inside their caps, which are exceeded, how long…

• 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 user has hit a wall, cannot access a service from their region, or wants a no-cos…

• 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's terms decide whether you may publish at all, and China's AI-content labelling…

• 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 number, its official pages contradict each other, it says the allowance changes at…

• 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. Use this when a user names the stack they rel…

• 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 watermark looks like, design tools on whether you can export and license the result,…

• 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 advice; details and obligations live on the publish-check page.

• 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 with the changed fields, the current wording, the verification date and the sou…

• 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, status, transport, origin, keyword, or `since` (first-seen date) to poll it like…

• 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/description as fetched, its page on Baipiaoji (curated records only), and a verification…
