backstory: having helped build Viv (basically Siri 2.0) w/ the ex-Siri team, it was apparent that assistants tend to fail when they're overly broad and opaque because people don't know what they can / can't do. Fastlane helps you build niche conversational AI experiences that can be really exceptional within a narrow, but deep, knowledge domain.
what: LLM prompt management (e.g. ChatGPT / OpenAI) that lets you tightly control history, prompt order and weighting, identity / personality, and LLM settings
who it's for (for now): builders, prompt engineers, ChatGPT power users, app developers
future: we're extending Fastlane's capabilities soon beyond prompt management so you'll be able to upload data and extend a persona's memory / knowledge, have multi-modal outputs, and more.
ask: let us know what you need! We're builders ourselves, building Fastlane so we can more easily build AI products. We just want to help enable people like us
