## HousePlan

HousePlan positions itself as a modern alternative to heavyweight architectural drafting software. Instead of sketching by hand or wrestling with CAD tools, you describe the home you have in mind — or hand the AI a reference image — and the platform proposes layouts that already respect basic space-planning logic. From there you can adjust room types, dimensions, and circulation until the plan matches how you actually want to live.

The tool covers several distinct workflows under one roof: whole-house floor plans, home and exterior design, interior design, garden and landscape layout, plus niche templates such as restaurant plans, mid-century plans, and barndominium plans. A 2.5D view is offered as a middle ground between a flat drawing and a full 3D model, which many users find easier to read and present to clients.

Collaboration and project management are part of the pitch: plans are saved under My Projects so homeowners, designers, and builders can review the same layout and discuss changes against a shared visual. HousePlan works as a freemium product — you can start exploring plans for free, with paid tiers available for heavier use.

**Pricing & Plans:** Freemium. A free entry point lets you generate and explore plans, with paid plans available for higher usage; check the site for current tier details and limits.

- **Prompt and image-to-plan generation:** Describe your home in words or upload a reference image and let the AI produce a structured floor plan draft.
- **2D, 2.5D and 3D views:** Switch between flat plans, a semi-perspective view, and 3D visualisation to read a layout from the angle that suits you.
- **Specialised plan templates:** Beyond standard homes, the platform includes templates such as restaurant plans, mid-century plans, and barndominium plans.
- **Interior, exterior and garden design:** Extend the same project into interior layouts, facade concepts, and garden or landscape arrangements.
- **My Projects workspace:** Keep layouts organised so homeowners, architects, and builders can review and iterate on the same plan.

**Strengths:** Very fast way to get a first layout from a plain-language prompt; Covers floor plans, interiors, exteriors, and gardens in one workspace; 2.5D view is easy to read and present to non-specialists; Useful for renovation projects where the existing structure must be respected

**Limitations:** Pricing tiers and usage limits are not clearly documented on a dedicated page; AI-generated plans still need professional review before construction; Best results depend on how clearly you describe the space

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
