WriteHuman, a better alternative to StealthGPT
WriteHuman vs StealthGPT: real-world performance
WriteHuman ranked #1 of 14 humanizers tested in September 2026
HumanizerBench is a public benchmark that re-tests every major AI humanizer each month. Each tool is paid for and run by hand on the same prompts, then scored against 5 major AI detectors on how human the output reads, how well it keeps the original meaning, and how cleanly it's written. Every prompt, output, and detector score is published.

10 Tips for Houseplants for Low-Light Apartments
We have all lived in a cozy apartment with windows that face...well, another brick wall. It can be disheartening to scroll through Instagram and see sun-drenched urban jungals. You may be tempted to give up gardening since you don't have a greenhouse, but there is no need to give up yet! With a bit of effort, you can be a successful plant parent too!
Here are 10 tips that will help your plant friends Survive and thrive in your low-light apartment.
- Pick the Right Crew
The first thing you need to do is leave the succulents at the nursery. Plants that do well in low-light conditions include: snake plants, ZZ plants, cast-iron plants, and pothos.
- Put Them on a Water Diet
Since your plants will "drink" their water slower in low-light conditions, you will need to water them less. To check if the soil is dry, stick your finger two inches into the soil and see if it is dry. If it is still moist, then you don't need to water that plant. Overwatering is a common mistake that people make with low-light plants.
- Dust Those Leaves
Since there is less light, your plants will need to absorb every bit of light that they can. Dust will block light and prevent photosynthesis. To remove dust, you will need to wipe the leaves with a damp cloth.
- Mirror, Mirror on the Wall
A low-cost way to increase the available light in a room is to hang a mirror opposite your window. The light will bounce off the mirror and increase the available light in the room.
- Keep ‘Em Clean and Yellow-Free
Remove yellow and brown leaves. Your plant spends energy trying to save dying leaves, and you want it to save that energy to help the healthy parts of the plant.
- Rotate for Even Tans
Plants tend to grow long and lanky in the direction of the light source. This creates an unsightly effect called etiolation. To avoid this, simply quarter turn your pots every week.
- Think White and Bright
When painting or buying pots, choose light colors. Light colored walls and pots reflect light and help to brighten dark corners.
- Fake It with Grow Lights
If you don’t have any natural light, you don’t have to worry about your plants dying. You can buy desk lamps with embedded LED grow bulbs to fool your plants.
- Ditch the Heavy Fertilizer
Plants that don’t get a lot of light grow really really slowly. Fast plant growth means they need more food, so during the growing season in the spring and summer you can fertilize them, but not during the lazy winter months.
- Group Your Greenies
Plant grouping is not only cute, but creates a microclimate with more humidity. When plants evaporate water, it helps prevent the brown, crispy edges.
As you can see, having a sunroom is not a must to have lots of plants. Happy planting!
Each tool was run by hand and screen-recorded during the September 2026 run. The outputs are then scored programmatically against five major AI detectors, and every input, output, and detector score is published on GitHub. Watch the unedited humanization sessions (video opens in a new tab):

Benchmark results
WriteHuman scored 78.29. StealthGPT scored 65.10.
HumanizerBench is a public monthly benchmark of AI humanizers. It pays for every tool, runs each one by hand on the same prompts, and publishes its inputs, outputs, and detector scores so the results can be checked. The September 2026 cycle ran 462 tests across fourteen humanizers and five AI detectors. WriteHuman finished first with a composite of 78.29. StealthGPT finished ninth at 65.10, a gap of 13.19 points.
The number underneath that spread is the AI-detector pass rate. StealthGPT was tested on its Essential plan and its output read as human-written on 79.6% of runs. WriteHuman was tested on its entry-level Basic plan and posted 90.1%. At 79.6%, roughly one StealthGPT run in five still came back reading as AI, which is the practical version of the complaint third-party reviewers keep repeating: the tool reports a passage as human while outside detectors do not.

Detector results
WriteHuman was ahead of StealthGPT on four of the five AI detectors
WriteHuman came out ahead on four of the five detectors in the September 2026 cycle. On Winston AI, WriteHuman's output read as human-written 84.1% of the time against StealthGPT's 66.6%. On ZeroGPT it was 77.8% versus 68.9%. On Copyleaks, 86.7% versus 81.8%. On Originality.ai, 91.4% versus 89.5%.
Winston AI is the one worth pausing on, because that 17-point spread is the widest of the four and Winston is a checker clients reach for early. StealthGPT cleared it on two runs in three. WriteHuman's built-in AI detector is tuned to closely match GPTZero, Originality.ai, Copyleaks, ZeroGPT, and Winston AI, and it sits in the same view as the humanizer, so you can see roughly where a passage will land before you publish it rather than finding out on someone else's checker.

Consistency and meaning
Steadier across formats, and it keeps more of what you wrote
The benchmark breaks results down by what you are actually writing, and news articles are where the September 2026 gap is starkest: 89.2% for WriteHuman against StealthGPT's 58.7%. On a news-style draft, four StealthGPT runs in ten still read as AI.
That unevenness is what the benchmark's consistency measure captures, and WriteHuman scored 82.1% on it against StealthGPT's 63.1%. WriteHuman also kept more of the original meaning intact, 72.3% versus 59.4%, and picked up fewer quality penalties: none at all, against StealthGPT's five points. Taken together that is the difference between a tool you can paste anything into and a tool that needs you to guess which formats it happens to survive.

Pricing
StealthGPT starts at $34.50/mo. WriteHuman starts at $20
StealthGPT's pricing page lists four tiers: Essential at $34.50/mo, Pro at $30/mo (marked Most Popular), Business at $100.50/mo, and Enterprise at $499.50/mo. There is no permanent free tier. Access is gated behind a signup, and trial availability has been inconsistent across review sites in 2025 and 2026.
WriteHuman starts at $20/mo for Basic, $29/mo for Pro, and $59/mo for Ultra, and the humanizer is free to use on smaller passages with no signup at all. For most writers and creators, that means you can validate output quality before paying anything.

Quality
Independent tests are mixed on StealthGPT
StealthGPT's marketing claims it produces output that scores well on every major AI detector, including Turnitin. Independent 2025 and 2026 reviews tell a different story. Long-form reviewers consistently report that StealthGPT output gets flagged by Turnitin and Originality.ai, even when the tool's own in-app checker reports the same passage as 'human.' AIDetectPlus called StealthGPT "by far the worst humanizer I tried," describing the output as gibberish you cannot actually submit.
There is also a recurring quality complaint in the same reviews: grammar slips, awkward phrasing, and the occasional incoherent sentence on longer drafts. Reviewers warn against trusting the built-in score in isolation.
WriteHuman's humanizer is tuned to preserve grammar and meaning on the first pass, and the built-in detector is tuned to closely match what external tools will report.

Daily caps
Every paid plan below Enterprise has a daily request limit
Essential users get 50 humanization requests per day. Pro gets 100. Business gets 500. Only the $499.50/mo Enterprise plan is unlimited. For a heavy week of client revisions or content batches, that ceiling is real, and you cannot lift it without jumping tiers.
WriteHuman has no daily-request cap on paid plans. Ultra is unlimited at $59/mo, so you can iterate as much as you want without watching a counter tick down.

Pricing optics
Displayed as daily, billed monthly. The real cost stacks up fast.
StealthGPT's pricing page shows every plan as a daily rate. Essential is $1.15/day. Pro is $1.00/day. Business is $3.35/day. Enterprise is $16.65/day. The numbers feel small because they are framed against a day, but there is no daily plan. You pay monthly. Multiply by 30 and the actual bill is $34.50, $30, $100.50, or $499.50 a month. Over a year, the cheapest StealthGPT plan costs $414 and you are still capped at 50 humanizations per day.
WriteHuman is displayed and billed the same way. Basic is $20 a month, or $144 a year. Pro is $29 a month. Ultra is $59 a month and unlimited. No daily-rate sleight of hand, no upsell to Enterprise just to escape a cap, and you can try the humanizer for free before paying anything.

What real StealthGPT users are saying
Quotes pulled from public reviews on Reddit, Trustpilot, G2, and Product Hunt.
“Trying to cancel was a nightmare. There's nowhere obvious to delete your account, so I had to block the payment with my bank to stop the charges.”
“StealthGPT was by far the worst humanizer I tried. It produces gibberish you cannot actually submit.”
“Long-form output of 2,000 words or more suffers meaning drift, and longer essays come back with more AI flags than shorter ones, the opposite of what you'd want from a tool marketed at content creators.”
