How to Use SynthQuery's AI Humanizer: Step-by-Step Tutorial

The SynthQuery Humanizer rewrites AI- or template-heavy text so it reads more naturally, with a side-by-side diff, readability context, and a built-in check against our own detector. This tutorial walks you from first login to confident, repeatable workflows—whether you edit one email or wire humanization into your stack.

1. Getting started: account, sign-in, and limits

Why you need an account

Humanization runs through SynthQuery’s authenticated API. After you register and sign in, you can paste text, choose settings, and run the tool without exposing keys in the browser.

Free tier (at a glance)

On the Free plan you get 1,500 characters per request and 3 analyses per hour (each Humanizer run counts as an analysis—see the Pricing FAQ). That is enough to polish short emails, captions, or a section of a blog post. If you routinely humanize long articles or decks, consider Starter, Pro, or Expert for higher per-request limits and, on Pro and Expert, API access—details on Pricing.

[IMAGE PLACEHOLDER: Pricing table excerpt highlighting Free vs Pro limits for characters per request and API access.]

Upgrade when: you hit character ceilings, need automation, or want priority throughput—compare plans and start a trial where available.

Dashboard and navigation

After sign-in, you can reach Humanizer from the product Dashboard (/dashboard) alongside detection, readability, and other tools. Bookmark Humanizer if you paste from drafts all day—your session stays consistent with the same usage meter and plan limits.

2. Basic usage: paste, configure, humanize

Step-by-step

1. Open AI Humanizer from the marketing site or your signed-in dashboard.
2. Paste your draft into the input area (up to the client-side cap; very long jobs may need splitting on lower tiers—see §6).
3. Choose a mode (tone/context) and intensity (how much rewriting)—explained in §3–4.
4. Optionally set readability target and Advanced options (§5).
5. Click Humanize (or use Ctrl+Enter in the text area).

[IMAGE PLACEHOLDER: Full Humanizer screen with input on the left, mode tabs, intensity buttons, and Humanize action visible.]

What you see after a run

• Human-like ring and AI score from the built-in bypass check (our detector scoring the output).
• Readability movement (e.g. Flesch–Kincaid-style metrics shown in the result).
• Original vs humanized diff so you can approve every change.

3. Modes vs intensity (don’t mix these up)

SynthQuery separates what kind of writing you want from how hard the model should rewrite.

Style modes (tone and genre)

Use the mode tabs to steer vocabulary and structure:

| Mode | Best for | | --- | --- | | Standard | General-purpose, neutral tone | | Academic | Papers, theses, scholarly tone | | Journalistic | News-style, article flow | | Creative | Narrative, marketing storytelling | | Professional | Reports, business, email | | Casual | Blogs, social, informal | | Technical | Docs, specs, precise terminology |

Modes shape voice; they are not the same as “light vs heavy” rewriting—that is intensity (below).

Intensity: Light, Standard, Aggressive

| Intensity | What it does | Tradeoffs (typical) | | --- | --- | --- | | Light | Subtle edits; preserves structure and meaning | Fastest feel per edit; highest meaning preservation; modest change to detector-facing patterns | | Standard | Balanced rewrite | Default for most marketing and support copy; good blend of quality and naturalness | | Aggressive | Heavy rewrite | Strongest push toward varied rhythm and phrasing; higher risk of small meaning drift—always diff-check |

In the UI, the middle intensity is labeled Standard (not “Medium”). Treat it as the balanced preset the brief calls “medium.”

---

4. Before/after examples by intensity

Same stub paragraph—only intensity changes (mode: Professional).

Source (generic AI tone):
“In today’s fast-paced digital landscape, it is important to note that leveraging cutting-edge solutions can unlock synergies across stakeholders. This article will explore key takeaways.”

Light (minimal changes):
“In today’s digital environment, using strong tools thoughtfully can help teams align. Below are practical takeaways.”

Standard (balanced):
“Teams move faster when they pick tools that fit real workflows—not buzzwords. Here are focused takeaways you can use this week.”

Aggressive (maximum rewrite):
“Skip the jargon. The right stack helps people ship; the wrong one adds meetings. What follows is a short list you can act on.”

Use Light when the draft is already strong. Use Standard for everyday production. Reserve Aggressive for text that still sounds like a template after one pass—then read the diff closely.

5. Advanced settings

Readability target (grade slider)

Set a target grade level so the humanized output matches your audience (e.g. wider reach vs specialist readers). The slider maps to grades 5–16; pair it with SynthRead if you tune content for a specific reading level.

Brand voice sample (optional)

Paste up to 4,000 characters of on-brand copy—help center snippets, approved marketing, or guidelines. The model uses it as a style reference (not a legal contract). Keep samples representative and non-sensitive.

Tips for voice samples: prefer one consistent channel (e.g. “how we reply to support tickets”) over a mix of legal, sales, and social copy in one paste; trim boilerplate; refresh the sample when your brand guidelines change.

Preserve formatting

Enable Preserve lists, headings, and line breaks when you are humanizing structured content (bullets, numbered steps, or sectioned docs) so layout does not collapse.

“Target audience” in practice

The product does not use a separate “audience” dropdown. Instead, combine mode (e.g. Casual for consumers, Technical for engineers) with readability target (grade-level alignment) and, when needed, a brand voice excerpt written for that audience. That trio usually replaces a single audience picker with more control.

6. Processing multiple documents (“batch” workflows)

There is no single batch upload button dedicated to humanizer in the current web UI. You can still scale work in three practical ways:

1. Chunk long sources within your plan’s character limit per request. Humanize section by section, then stitch—use consistent mode/intensity for even tone.
2. Queue work manually in the app: finish one run, copy or download, move to the next file.
3. Automate with the API (§7): loop over files in a repo or CMS export, POST each chunk to /humanize, and store outputs—ideal for teams on Pro or Expert.

7. API integration for developers

Pro and Expert include API access (see Pricing). The public surface is documented on API Documentation with an OpenAPI description—use the humanize operation and your server-side key from Account → API keys (after signup).

Typical integration pattern:

• Authenticate your backend (never ship secrets to the browser).
• POST text with the same fields you use in the UI: mode, readability_target, intensity, optional brand_voice_sample, preserve_formatting.
• Respect character limits and rate limits for your plan; handle 429 with backoff.
• Rotate keys from Account settings, log request IDs for support, and avoid sending regulated data you are not required to process—same hygiene as any other LLM-backed API.

OpenAPI and testing

The app exposes /api/openapi.json for machine-readable schemas; the API Documentation page links humanize next to detect, readability, and related endpoints so you can generate clients or paste samples into Postman-style tools.

[IMAGE PLACEHOLDER: api-docs page with humanize endpoint expanded and example JSON payload.]

Start building: Read the API docs and upgrade when you outgrow browser-only workflows.

8. Checking results: bypass score and optional full detection

Built into Humanizer

Every run includes a bypass check against SynthQuery’s detector: you will see whether the output passes our threshold, an AI score, and improvement vs the original when available. Treat this as a strong signal, not a guarantee—detectors evolve, and so do writing norms.

When to open the full detector

If you need sentence-level heatmaps, DeepScan (on supported plans), or a second opinion path, paste the humanized text into the AI Detector and compare. Many teams humanize → scan → light edit → final publish.

[IMAGE PLACEHOLDER: Humanizer result with Human-like ring, then arrow graphic to Detector page for a deeper pass.]

Verify before you publish: Humanize, then scan with the detector when stakes are high.

9. Tips for best output

• Length: Stay within your plan’s per-request limit; split very long pieces and keep headings consistent across chunks.
• Language: Match the language of your source; avoid mixing multiple languages in one paste unless you intend to.
• Format: Use preserve formatting for lists and docs; plain paragraphs are simplest.
• Iterate: Use Use humanized text as new input to run a second pass with different intensity or mode if the first pass is close but not quite right.
• Pair with readability: Cross-check with SynthRead when grade level and clarity are part of your acceptance criteria.
• Facts and quotes: Humanization can rephrase around proper nouns; verify statistics, legal language, and citations after any Aggressive pass.
• Chat and slash workflows: If you already use SynthQuery Chat with slash commands, you can route humanization from conversational flows—handy when the same team drafts in chat and then polishes in the dedicated tool.

Editorial checklist (2 minutes)

1. Skim the diff for unintended tone shifts.
2. Confirm bypass / AI score meets your internal bar—or run Detect.
3. Spot-check readability grades against your audience.
4. Copy or export, then publish.

10. Common issues and troubleshooting

| Issue | What to try | | --- | --- | | 401 / sign-in required | You must be logged in. Register or sign in, then return to Humanizer. | | Character limit exceeded | Shorten the input or upgrade for a higher per-request cap (Pricing). | | 429 rate limit | Wait for the hourly window to reset (Free: 3 analyses/hour) or upgrade. | | Output still “detectable” | Try Aggressive once, or change mode; then lightly edit the diff. Run Detect for detail. | | Meaning drift | Drop intensity to Standard or Light; reduce conflicting instructions in brand voice sample. | | Broken lists or headings | Toggle Preserve lists, headings, and line breaks and re-run. | | 503 / service not configured | Rare environment issue on self-hosted deployments; retry later or contact support if it persists. | | Inconsistent tone across chunks | Use the same mode and intensity for each section; keep a shared brand voice sample for the whole project. |

Quick comparison: intensity vs speed, quality, and bypass

Exact timings and bypass rates depend on text length, language, and model load—use this as a rule of thumb for planning:

| Intensity | Speed (relative) | Editorial risk | Typical bypass impact | | --- | --- | --- | --- | | Light | Fastest | Lowest | Incremental | | Standard | Medium | Medium | Solid default | | Aggressive | Can be slower / more edits to review | Highest | Often strongest, but verify facts |

Next steps

1. Create your account.
2. Open AI Humanizer and run your real draft with Standard mode + Standard intensity.
3. Review the diff, check the Human-like score, and optionally follow through AI Detector.
4. When you need scale, upgrade and wire the API.
