• get_eu_gdpr_tools read-only

  Find AI tools whose providers, on their own websites, refer to the GDPR or state EU data hosting. Each result quotes the provider's own sentence, links the source page and gives the date of GateOnAI's automatic check (about monthly). These are provider statements, not an audit, verification or certification by GateOnAI - check the provider's current documents before relying on them.

  • query — string — Optional: words to match in the tool name or tagline, e.g. 'transcription' or 'chatbot'
  • category — string — Optional category filter. Examples: 'writing-assistant', 'development', 'marketing', 'legal-ai'
  • standard — string — Compliance standard: 'gdpr' for tools whose provider pages refer to the GDPR, 'eu_hosted' for tools whose providers state EU hosting

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_prompts_for_profession read-only

  Get ready-to-use AI prompts for a specific profession from GateOnAI's library of 19,715 prompts across 65 professions. Works with ChatGPT, Claude, Gemini, and other LLMs.

  Parameters:

  • profession (required) — string — Profession slug. Examples: 'marketer', 'software-developer', 'designer', 'writer', 'content-creator', 'photographer', 'teacher', 'lawyer', 'doctor', 'entrepreneur'

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_site_stats read-only

  Get current live statistics about the GateOnAI platform including total listed tools, categories, tool compatibility connections, and prompt library size.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_compatible_tools read-only

  Find AI tools that may connect with a given tool, based on GateOnAI's IO-Compatibility Graph - computed automatically by matching the input/output content types (text, image, audio, video, code, etc.) that GateOnAI assigns to each tool. The tags are assigned automatically and can be wrong; connections are not tested. Answers questions like 'what tools work well with ChatGPT' or 'what can I feed ChatGPT's output into'. The graph has 76,183 computed connections.

  Parameters:

  • slug (required) — string — URL slug of the AI tool to find connections for. Examples: 'chatgpt', 'midjourney', 'claude'
  • limit — integer — Number of connected tools to return (default: 8, max: 20)

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• find_ai_pipeline read-only

  Find a computed sequence of AI tools that gets you from one type of content to another - e.g. audio to a finished blog post, or a single image to a full video. Powered by GateOnAI's IO-Compatibility Graph combined with a PostgreSQL recursive path-finding engine (not an LLM improvising) - each step is a listed tool whose tagged output type matches the next tool's tagged input type. The tags are assigned automatically and the pipelines are not tested. Returns multiple ranked alternative pipelines, each scored on tool quality and path length, so you can compare a fast 2-step option against a more thorough 4-step one. Valid content types: text, image, audio, video, data, url, code, pdf, email, social_post, prompt, file.

  Parameters:

  • start_type (required) — string — The type of content you are starting with
  • goal_type (required) — string — The type of content you want to end up with
  • free_only — boolean — If true, only return pipelines where every single tool in the chain is free or freemium
  • max_steps — integer — Maximum number of tools in the chain (2-6, default 4)
  • alternatives — integer — Number of alternative pipelines to return (1-5, default 3)

  Hints: read-only yes · destructive no · idempotent no · open-world yes

• whats_new read-only

  See real AI tools recently added to GateOnAI - based on genuine addition timestamps, not a guess or a static list. Optionally filter by category. Useful for staying current on new tool launches or checking what's new in a specific space (e.g. new AI Agents tools this week).

  Parameters:

  • days — integer — How many days back to look (1-30, default 7)
  • category — string — Optional category slug to filter by, e.g. 'ai-agents', 'marketing', 'design'. Omit to see all categories.

  Hints: read-only yes · destructive no · idempotent no · open-world yes

• find_similar_by_philosophy read-only

  Find AI tools that are conceptually or philosophically similar to a given tool - based on real semantic embedding similarity of each tool's name and tagline (MiniLM), not just shared category. Different from get_compatible_tools, which uses the structural IO-Compatibility Graph (real input/output matching) rather than meaning-based similarity. Use this for 'tools like X' questions, get_compatible_tools for 'what connects to X' questions.

  Parameters:

  • slug (required) — string — URL slug of the AI tool to find similar tools for. Examples: 'chatgpt', 'midjourney', 'notion'
  • limit — integer — Number of similar tools to return (default: 8, max: 20)

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_market_landscape read-only

  A real, computed statistical snapshot of one GateOnAI category: live tool count, real GateOnAI Score distribution (average/median/min/max) and current top-scoring tools. Every number is computed directly from live catalog data at request time - never a prediction, estimate, or industry-wide claim beyond what GateOnAI itself catalogs.

  Parameters:

  • category (required) — string — Category slug, e.g. 'ai-agents', 'design', 'marketing', 'writing-assistant'. Use search_ai_tools or browse to find valid category slugs if unsure.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• match_prompt_to_task read-only

  Given a free-text description of a task (e.g. 'write a cold email to a client'), finds the best-matching existing prompt(s) from GateOnAI's prompt library using real BM25 full-text search - not a semantic guess or an invented relevance score. Each result includes the actual prompt text, which tool it's designed for, and the profession it comes from.

  Parameters:

  • task (required) — string — Free-text description of the task, e.g. 'write a cold email to a client' or 'summarize a legal contract'
  • limit — integer — Number of matching prompts to return (1-10, default 5)

  Hints: read-only yes · destructive no · idempotent no · open-world yes

• get_workflow_template read-only

  Get one of GateOnAI's 2,957 pre-built, ready-made AI workflows for a specific profession - a deterministic, ordered sequence of steps each matched to a real tool by category and GateOnAI Score, regenerated live from current tool data. Different from get_ai_workflow: this returns an existing, pre-built template for a known profession rather than generating a new custom one from free text - faster and more consistent for common roles.

  Parameters:

  • profession (required) — string — Profession slug. Examples: 'blogger', 'general-contractor', 'marketing-manager', 'software-developer', '3d-artist'. If unsure of the exact slug, use get_ai_workflow instead with a free-text description.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• build_workflow_board read-only

  Turn a goal described in plain language into a GateOnAI Workbench board: real tools from the GateOnAI catalog, connected step by step when they form a workflow. Returns the steps and a share link that contains the board itself - nothing is stored on GateOnAI's servers. The user can open the link, clone the board into their own Workbench and share it. Use when the user wants a ready-made, visual AI workflow they can open and edit.

  Parameters:

  • goal (required) — string — What the user wants to achieve, e.g. 'turn podcast episodes into blog posts and short social clips'

  Hints: read-only yes · destructive no · idempotent no · open-world yes

• analyze_ai_stack read-only

  Automated observations about a set of AI tools (2-40 GateOnAI tool slugs): tools not currently listed, category overlaps and data connections found in GateOnAI's IO-compatibility graph. Observations from GateOnAI data only - not recommendations and not judgments about any provider.

  Parameters:

  • tool_slugs (required) — array — GateOnAI tool slugs, e.g. ['chatgpt', 'elevenlabs', 'opus-clip'] (slugs appear in search results and tool URLs)

  Hints: read-only yes · destructive no · idempotent yes · open-world yes
