toolmark.aiAbout Toolmark AI
Toolmark AI is a no-code builder for single-purpose AI tools and Chrome extensions, aimed at people who want to ship and monetise a narrow tool rather than build a full application. You assemble it with a drag-and-drop builder, define your own prompts, chain multiple prompts for multi-step logic, and pull data from user input or from prior actions into later steps. Model access is broad and switchable with a click — GPT-4o, DALL·E, Google Gemini, Midjourney, Llama and Mistral among others — covering text, image and voice generation, so the tool is not locked to one provider's behaviour or pricing. Finished tools embed on your own site, or ship as a Chrome extension, and integrations through Zapier and Airtable connect them into existing automation. There is a public community catalogue where users publish tools others can run, which doubles as a distribution channel and as a source of working examples; the company's own published tools include a summariser, an outfit try-on, a blog post writer, a cover letter writer, a recipe generator and a city guide. Both paid tiers include unlimited tool creation and unlimited publishing. The pricing is metered in an unusually transparent way: a fair-usage policy charges by action execution time, $0.002 per second on Starter and $0.001 on Pro, with your base plan fee covering usage up to that same dollar figure before overages begin — and the site works the arithmetic out with a concrete example.
