Free Feng Shui Floor Plan Tools Compared (2026)

The comparison table

Six tools, six different jobs. I have included my own analyzer in this table, so read the row with appropriate scepticism and check the others for yourself.

Checked August 2026. Free tiers and features on these platforms change often, so verify current terms on each site before relying on them. Where a tool does not publish its methodology, I have said so rather than guessed.

What AI floor plan tools do well

I want to be straight about this, because the easy move for a consultant is to dismiss free tools, and it would not be honest. These tools do several things genuinely well.

• They read a plan faster than most people can. Upload a photo of a floor plan and the room structure comes back identified. That used to be the slow part of any self-assessment.
• They catch the obvious problems reliably. Bed under a beam, bed sharing a wall with a toilet, main door aligned straight through to a window, stove directly opposite a sink. These are real classical concerns and the tools do flag them.
• They explain in plain language. No jargon barrier. NineFengShui in particular runs a rule engine first and uses AI only to write up the result, which is the right way round.
• Some name their method. LumenFeng says Eight Mansions and calculates a Kua number. That is a real classical system, applied consistently.
• They cost nothing and commit you to nothing. For someone deciding whether this subject is worth their attention at all, that matters more than depth.

If your question is where to put the bed in a rented room, a free tool answers it. Paying a consultant for that would be poor value and I would tell you so.

What they cannot do

There are three gaps, and they are structural rather than a matter of the software improving next year.

Timing

Every tool in the table analyses space. None of them analyses time. That is the honest headline of this comparison, and it is why the renovation timing column reads No all the way down for the AI tools.

A home's chart changes every year, in early February. A sector that is neutral in 2025 can hold the year's heaviest affliction in 2026. More importantly for anyone about to renovate, the risk is not just where you work but when you break ground and in what order. Selecting a renovation start date means screening the almanac for month break days, year break days, solar term boundaries and days unsuitable for disturbing earth, then checking those days against the afflicted sectors, then matching what survives to the occupants' own charts. No floor plan tool does this, because it is not a floor plan problem. I have set out the full process in the 2026 renovation guide, which also includes a free tool that tells you whether your specific sector and scope can proceed this year.

Afflicted sectors for the current year

Related but distinct. Some tools show annual star data, NineFengShui among them, and my own analyzer is built around the 2026 annual chart specifically. But several tools in this list do not calculate annual afflictions at all, which means a layout they call fine can sit directly on top of the year's Tai Sui or Three Killings position. That is not an error in what they told you. It is a question they were never asking.

The people in the home

This is the deepest gap. Classical feng shui reads three things together: the building, the moment, and the people. A tool sees the building. Some ask for one birth date and derive a Kua number or a Day Master from it, which is a real step in the right direction.

What none of them do is weigh a household. Four people live in a home, their charts differ, and the same bedroom is favourable for one of them and not another. Recommendations conflict. Somebody has to decide which two of five findings actually matter for this family, and rank them against the budget and the constraints. That judgement is the work, and it is not a lookup.

When a free tool is enough, and when you need a human

A clean line, in both directions.

A free tool is enough when: you are curious rather than committed; you are comparing two units before you buy; you are rearranging furniture in a rental; you are deciding which bedroom goes to which child; or you want to understand the vocabulary before you pay anyone anything. In all of these, use a free tool. You will get a real answer and it will cost you nothing.

Bring in a human when: money is about to be spent irreversibly, meaning a renovation or a property purchase you will hold for a decade; the findings conflict and you cannot tell which to prioritise; a business premises is involved, where layout, staff positions and timing all interact; someone in the household has been unwell, or one part of the home is consistently associated with problems; or you need a date, which is the one thing no tool in this list produces.

My own analyzer sits deliberately on the free side of that line. It shows you the 2026 sector map of your home and stops there, because the next step needs your birth chart, and that is a conversation rather than an upload.

"Use a free tool to understand your space. Bring in a human when the decision is expensive, irreversible, or personal to the people living there."

Frequently asked questions

What is the best free feng shui floor plan tool in 2026?

It depends on what you are trying to decide. For a quick read on one room, LumenFeng is the most focused option, because it works from your personal Kua number and Eight Mansions (Ba Zhai) directions and gives you bed and desk placements you can act on the same day. For a whole-home assessment with real chart depth, NineFengShui is the strongest of the AI tools, since it maps your plan to a nine-grid and layers Flying Star and Ba Gua palace analysis on top, with two free reports a month. For seeing which parts of your home fall into 2026's afflicted sectors before a renovation, my own analyzer is built specifically for that and stays free. If what you actually want is to design the space in 3D and treat feng shui as one input among many, Coohom and Arcadium 3D are better tools for that job than any of the analysis-only options. There is no single winner, because these tools are answering different questions.

Can an AI tool tell me if my home has good feng shui?

It can tell you a useful and genuinely accurate part of the answer. AI floor plan tools are good at the spatial layer: reading a plan, identifying rooms and furniture, mapping the layout onto a grid, and flagging the well-known layout problems such as a bed under a beam, a door aligned straight through to a window, or a stove placed directly opposite a sink. Those findings are real and worth having. What they cannot assess is the time layer and the person layer. Feng shui in the classical sense is the interaction of three things: the building, the moment, and the people inside it. An AI tool sees the building. It does not know that your annual chart changes every February, it does not usually weigh the occupants' own birth charts against the sectors they sleep in, and it cannot tell you when to act. So treat an AI verdict as a description of your space rather than a judgement on your home.

Do free feng shui apps use real classical feng shui?

Some do, and it is worth checking which. LumenFeng states that it works from Eight Mansions (Ba Zhai) and calculates your personal Kua number, which is a genuine classical system. NineFengShui uses Flying Star methodology with Ba Gua palace analysis and takes your Day Master into account, and describes a rule engine doing the calculation before AI turns the result into readable language, which is the right order. My own analyzer runs the 2026 annual Flying Star chart against your measured door facing. Others are less specific. Some tools do not publish which school or method they use at all, and platforms whose main product is 3D interior design tend to treat feng shui as a layout and content layer rather than a calculation engine. Neither approach is dishonest, but they are not the same thing. If a tool will not tell you what system it is using, that is the question to ask before you rely on the output.

Can any free tool pick my renovation start date?

No. At the time of writing, in August 2026, none of the free feng shui floor plan tools select a renovation or groundbreaking date. They analyse space, not time. Date selection is a different discipline. It means screening the almanac to remove month break days, year break days, solar term boundaries and the days classified as unsuitable for disturbing earth, then checking the surviving days against the annual afflictions in the sector you intend to hack, and finally matching what is left to the birth charts of the people who live in the home. The last step is the one that cannot be generalised, because a day that is clean by almanac standards can still clash directly with the chart of the person paying for the works. Almanac apps can show you generic good days. That is not the same as a date selected for your renovation, your sector and your chart.

Is a free feng shui tool enough, or do I need a consultant?

A free tool is genuinely enough in several situations. If you are curious rather than committed, comparing two units before you buy, rearranging furniture in a rental, deciding which bedroom to give which child, or you simply want to understand the vocabulary before paying anyone, a free tool will serve you well and you should use one. Where free stops being enough is when money is about to be spent irreversibly. A renovation, a purchase decision on a property you will hold for a decade, a business premises, or a household where someone has been unwell or something has gone consistently wrong in one part of the home. Those cases involve trade-offs between competing findings, and a tool that outputs a list cannot tell you which two of five recommendations actually matter for your household. The practical rule: use a free tool to understand your space, and bring in a human when the decision is expensive, irreversible, or personal to the people living there.

Where to start

Whichever tool you pick, start by getting an accurate floor plan and a proper compass reading of your main door. Every tool in this list is only as good as those two inputs, and a guessed facing direction will produce a confidently wrong answer on any platform.

If you want to see the 2026 picture for your own home, the free feng shui analyzer takes about two minutes. If you are renovating, read the 2026 renovation guide first, because the sector map is only half of that decision.
