Building Custom Skills Directly in Google Docs: A Complete Guide

Google Workspace Skills is rolling out across Google's ecosystem faster than ever. What's interesting here is that you're no longer confined to using Gemini in isolation. Instead, you can ask Gemini to build, refine, and validate custom skills for your Google applications without switching windows. It's a significant workflow improvement for teams relying on Google's suite.

Once you enable a skill, Gemini can recognize when it's the right tool for the job and apply it automatically. Alternatively, you can manually invoke the skill whenever you need it. Here's the breakdown of how to get started.

Creating Skills in Google Docs: Step by Step

A quick heads-up: this feature is still in beta and only available in select regions, so full rollout will take some time.

Step 1: Access the Skill Builder

Open Google Docs and locate the Gemini icon at the bottom of your screen. Click the three horizontal lines menu and select Skill builder to begin creating your skill.

Building a skill in Google Docs

From here, you'll instruct Gemini to generate a skill based on template documents you provide. In this example, we're creating a Proposal Automation Skill that learns from your existing proposal templates.

Create a proposal automation skill based on these examples: Full Cymbal Proposal, Cymbal Investment Proposal. Integrate HubSpot and past sales history for accuracy, analyze requests against historical sales, and maintain our brand voice. Once finalized, automatically share the document in the Chat.

The result? A new skill called Proposal Architect that automates the entire proposal creation and management workflow using Gemini and Google Workspace tools. This is exactly the kind of time-saver teams need.

Your newly minted skill automatically syncs across all Google Workspace applications, ready to be called whenever you need to generate content. On this screen, click Add to Workspace Studio to integrate the skill into your workspace.

Step 3: Activate Your Skill

Navigate to Workspace Studio, and you'll see your new skill displayed with details about its functionality—in this case, generating proposals and presentation slides for business use. Hit the Turn on button to activate it across your workspace.

Enabling a skill in Google Workspace Studio

Now jump over to Gmail (or any other Google app). Click the Gemini icon and draft a message. In the chat window, type your request for an email, then enter @ followed by your newly created skill name. Gemini will generate content aligned with that skill's training. The real concern is ensuring your skills are specific enough to produce consistently useful results—too broad, and you'll get generic outputs.

11 Telltale Signs That an Image Was Created by AI

11 Telltale Signs That an Image Was Created by AI

That celebrity photo circulating on social media? The product shot in an online ad? That suspiciously perfect portrait on a dating profile?

Any of these could have been generated by artificial intelligence. And as we head into 2026, fake images are becoming increasingly sophisticated.

Here's the good news: AI image generators like Midjourney, Adobe Firefly, and GPT Image 2 still make predictable mistakes—if you know what to look for. This guide walks you through 11 reliable methods to detect AI-generated imagery.

1. Distorted Hands and Fingers

AI image generators—including Midjourney—have long struggled with rendering hands correctly. Fingers often appear too long or too short:

AI-generated image showing abnormally long or short fingers

Sometimes the hand itself has too many or too few digits:

AI-generated person with incorrect number of fingers

Or the hands look warped and malformed. In this example, a woman has four fingers on one hand, with the fifth digit appearing to sprout from her skirt:

AI-generated image with deformed hands

Here's what's important to know: Don't rely blindly on this trick anymore. The latest generation of models—GPT Image 2, Midjourney V8.1, and FLUX.2—now render hands with impressive accuracy. This image, created with GPT Image 2, features anatomically correct hands with natural skin texture:

Current AI-generated image from GPT Image 2 with anatomically correct hands

So here's the takeaway: deformed hands are strong evidence of AI generation, but perfect hands don't prove an image is authentic.

2. Missing or Duplicated Elements

Beyond hands, other objects frequently appear incomplete or repeated. Take this lion, which only has one ear:

AI-generated lion with only one ear

Or this T-Rex, which somehow sprouted three arms:

AI-generated dinosaur with three arms

3. Unnaturally Flawless Skin

Many AI image generators produce skin that's suspiciously perfect. That means zero wrinkles, blemishes, facial hair, or moles—essentially digital airbrushing taken to an extreme:

AI-generated person with impossibly smooth, flawless skin

That said, this particular image was created with Midjourney and isn't an extreme example. It could also be a lightly Photoshopped photograph.

With other tools, this "perfect skin" problem becomes far more obvious and jarring.

4. Garbled or Nonsensical Text

Most AI image generators struggle to render readable text accurately. Midjourney included.

Letters often appear distorted, duplicated, scrambled, or missing entirely.

In this logo example, the word "Munchkin" should be spelled clearly, but instead it's mangled:

AI-generated image with nonsensical text—missing or duplicated letters

The newest generation has caught up here. GPT Image 2 now leads the pack in text rendering accuracy, even correctly displaying German umlauts, as shown in this AI-generated sign:

Current AI-generated image from GPT Image 2 with accurate text including German umlauts

So garbled text mainly reveals images from older or cheaper models.

5. Illogical Architecture

AI models often struggle with architecture, especially complex structures like castles or fortifications.

This castle image looks decent at first glance:

AI-generated castle with errors and inconsistencies

But look closer and you'll spot several inconsistencies:

  • Stairways that defy logic
  • Towers that appear warped or asymmetrical
  • Windows that are distorted or misaligned
  • Rooflines and dormers that bend unnaturally
  • Chimneys in odd locations
  • Brickwork laid incorrectly
  • And more...

6. Unnatural Lighting and Shadows

Simulating light and shadow realistically is a complex task that trips up most AI models. So if you spot an image where the lighting and shadows don't quite match up, it might be AI-generated.

In this DALL·E 3 image, the shadows cast by beachgoers are inconsistent and look wrong. Some shadows are too long, too short, cut off, or too dark. Others don't align with the sun's position, or they're missing entirely:

AI-generated image with unnatural shadows

7. Check the Filename

If the filename hasn't been changed before uploading, you can often determine whether an image was AI-generated—and sometimes even which tool created it.

Midjourney image filenames follow this pattern:

Username_Prompt_JobID.png

Example:

blogmojo_superheroine_sailor_with_blue_dress_maritime_backgroun_fc50e595-3c9d-419d-a3e7-ce0ce9f9089a.png
Identifying Midjourney images by filename

With DALL·E 3 (replaced by GPT Image and fully discontinued by OpenAI in May 2026), it was even more obvious—not only the prompt but "DALL·E" itself appeared in the filename. Many such files are still circulating online:

DALL·E images can also be identified by filename

8. Examine the Metadata

Beyond the filename, you can also inspect an image's metadata to determine whether it was AI-generated.

Real photographs contain camera information—brand, model, and lens used—plus technical data like aperture, shutter speed, and focal length:

Authentic photos typically contain camera metadata

AI-generated images lack this camera metadata. Instead, they increasingly carry embedded provenance information:

  • C2PA Content Credentials: OpenAI embeds C2PA metadata into all images generated via ChatGPT or the API (GPT Image). You can verify this free at contentcredentials.org/verify.
  • SynthID: Google watermarks images from Gemini and Imagen with an invisible marker that persists through cropping, screenshots, and light editing. In the Gemini app, you can directly ask whether an uploaded image carries the SynthID watermark, though the accuracy isn't guaranteed—a July 2026 investigation found Gemini sometimes carries over verdicts from the first image in a conversation.

Both methods have limitations, but they're currently the most reliable first-pass checks for suspicious images.

Note: Of course, metadata can be manipulated and added to AI images after the fact. Conversely, real photos can have their metadata stripped—something many image compression tools do by default.

9. Verify the Source

Whenever you encounter an image online, always check where it came from. Who uploaded it? Where did they source it? Have any credible news outlets independently confirmed the image?

If you're uncertain, run a reverse image search using Google Images. Click the camera icon ("Search by image") on the right side of the search bar:

Verify images using Google reverse image search

This shows whether the image has appeared elsewhere previously or if similar versions exist online. You can also check whether credible news outlets have reported on the event the image allegedly depicts.

10. Look Closely at the Details

AI image quality improves constantly. The best ones today are almost indistinguishable from real photographs. But they still typically show subtle tells.

AI images are trained on existing photos, so the models often struggle with uncommon details that rarely appear in training data.

Take this example. Most of the image looks fairly realistic, but the fingers on the person's right hand have an unnatural appearance—a helpful hint that something's off. If the hands don't tip you off, examine the text on the F1 jacket more closely. Those letters are complete nonsense, a common giveaway in AI images, since the technology still struggles with small details like text and logos.

11. Be Suspicious of Perfection

Another effective way to spot AI images is to notice whether they look unnaturally flawless.

AI-generated images often lack the natural texture and imperfections inherent in real photographs. This gives them an overly processed appearance, like they've been run through aggressive smoothing filters or blemish removal.

This image might initially remind you of a famous pop star, but the face lacks natural texture and detail. It's too sharp, too smooth, too perfect—all red flags suggesting AI generation.

The background can also be a giveaway. AI images often feature impossibly perfect or fantastical settings. For instance, a flock of flamingos in the background might seem normal, but in this case, it signals another detail suggesting something's amiss with the image.
