Plan a date in one conversation.

How it works
From a sentence to a plan you can actually follow.
Planning a date in Korea usually means jumping between map apps, blogs and review pages. AI Date does that work in one chat.
지도 앱, 블로그, 리뷰를 오가며 동선·영업시간·예산을 맞추던 일을 대화 한 번으로.
Describe the date
Area, time window, budget, food preferences and mood, in Korean or English.
“홍대에서 금요일 저녁, 둘이서 7만 원, 활동적인 코스”
Get a course
Claude searches for real candidate places and orders them into a timeline (for example: activity, café, dinner, walk) that fits your time and budget.
Swap and check
Swap any stop for an alternative that still fits the rest of the course, and open a candidate to see its menu, price range and reviews.
Features
Designed around how couples actually plan.
Swap any stop
Don’t like the café? Swap it. The course is re-checked so timing, distance and budget still work.
Place details
Each candidate shows menu, price range, hours and reviews, from licensed place-data APIs (planned).
Grounded picks
Venues come only from place-search tool results, so the model can’t invent a restaurant that doesn’t exist.
Fits budget and time
Budget, time window and opening hours are treated as hard constraints and validated on every course.
How we use Claude
Claude plans the course. Tools keep it real.
Claude is part of the product runtime, not just a development tool. Every planning request runs through the Claude Messages API with tool use and returns schema-validated JSON.
1 · Planning request
2 · Response
place_id that came from a tool result in the same session. Claude ranks, sequences and explains; it cannot add a venue that the tools did not return.Tool use
Typed, read-only tools for place search, details, alternatives and travel time, executed on our server.
Structured output
Courses follow a fixed JSON schema (stops, times, costs, reasons) so the app can render and edit them.
Prompt caching
System prompt and tool definitions sit in a cached prefix, keeping repeated swaps in one chat fast and affordable.
Model routing
A smaller Claude model parses requests and handles quick swaps; a larger one plans full multi-stop courses.
Course-quality evals
Offline test requests scored on schema validity, budget fit, hours, travel distance and grounding.
Built with Claude Code
Our team uses Claude Code to write, test and review the codebase. Every change is reviewed by a person.
Roadmap
Where we are, and what’s next.
AI Date has not launched. Everything after the current phase is a plan, not a commitment, and we haven’t set a launch date.
Core planner
Chat flow, course JSON schema, tool definitions and prompts on the Claude API; first course-quality eval set.
Licensed place data
Connect licensed place-data APIs for real places, hours, menus, prices and reviews, with attribution.
Closed beta in Korea
A small test with real users, then iterate on course quality, latency and cost.
Public launch
Web first, then mobile apps, once quality and data licensing are in place. No date set.

FAQ
Frequently asked questions
Can I use AI Date today?
Not yet. AI Date is in development and has not launched. There are no public users, and there is no app to download yet. If you’d like to hear about a beta, email hello@purifysec.com.
Where will menus, prices and reviews come from?
From licensed third-party place-data APIs (for example, map and local-search providers), shown with source attribution. These integrations are planned and not live yet. Claude does not write menus, prices or reviews.
Can Claude make up places that don’t exist?
The system is designed to prevent it. Claude can only reference places through IDs returned by our place-search tools in the same session, and the server rejects any course that contains a place ID that didn’t come from a tool result.
How does AI Date use Claude?
Claude is the planning engine. Each request goes to the Claude Messages API with tool definitions; Claude calls place tools, then returns a course as JSON that we validate against a schema. We use prompt caching for follow-up swaps and route between smaller and larger Claude models by task. We also build the product with Claude Code. Technical details.
Is AI Date affiliated with Anthropic?
No. AI Date is an independent product built on the Claude API by Purify Solution Co., Ltd. It is not affiliated with or endorsed by Anthropic.
