One AI character, one month of client posts: how an agency plans it
Short answer: Treat a recurring AI character as a project with a contract, a calendar and an exit plan, not as a prompt. Agree the character in writing, split 12 to 20 posts into a few scene families, build and test the reference set before the month starts, and approve in two gates. Higgsfield, an online platform that bundles many AI image and video models, can do the batch work, but its Soul ID feature, which learns one person's look from photos, cannot be exported as a file, so settle what the client receives at exit before you begin.
A client wants the same character across a month of posts. Making each one by hand burns hours and the look drifts. You want to know how to plan the month so it is profitable and survives a change of tool or a change of mind.
I'm Ranjit, and I run Blur Studio: 15+ years building software, 120 apps taken live, and clients who have gone on to raise $10M+. I build AI systems and processes that help businesses do a lot more with a lot less time. I also work differently from most of what else is out there, more on that further down this page. Say hello.
Most guides on AI characters show you how to make one good picture. An agency has a different problem: a client, a retainer, a month of posts, a person who approves, and a character that has to look the same in week four as in week one. The hard parts are not the prompts. They are the contract, the calendar, the approvals and what happens if the client leaves.
This page is the agency operations view. It does not teach you how to build the reference images themselves; for that, see how to keep a brand mascot consistent. It also does not cover disclosure rules for realistic faces in ads; see the rules for made-up models in ads. Here the focus is planning, capacity and risk. Ownership, liability and cost for the brand side are in daily posts from a branded AI character.

Cheapest first: draw it once and reuse it in a template
Before you plan an AI month, check whether you need AI. For a simple cartoon character, hire a freelance illustrator to draw 6 poses once. Then reuse them in a template tool such as Canva, an online design tool, with changing copy. It is often cheaper than AI for 12 posts, and it is 100 percent consistent. You also give the client a clean set of master files at the end.
If the client wants real authenticity, hire real creators instead of a character, and test the idea cheaply before you pay one. A character that talks every week in video is a different job again; tools made for talking faces, such as HeyGen, an online talking-avatar tool, suit that better than a still-image platform.
Agree the character in writing: spec, ownership and exit terms
Put the character in the contract, not only in the brief. Add one short paragraph, or a schedule, covering these points:
- What the character is. Role (mascot, host, product companion), personality, and the one-page spec: fixed traits, colour codes, forbidden changes.
- Who owns what. Who owns the final images and the reference set, which tool made them, and what rights the client gets. This is not legal advice, so have a lawyer review it, and check local law and each tool's current terms.
- The tool dependency. Say plainly that the character may live inside one vendor's account. Higgsfield's own help center says a Soul ID, its feature that learns a person's look from 20 or more photos, holds one person and cannot be exported as a standalone file. Do not tell a client they will own a reusable trained character if it only exists inside your account.
- What the client receives at exit. All approved images in full size, the spec, the winning prompts, the reference set and a note of which tool and settings were used.
- Change policy. What counts as a "new look" (a paid change) versus a fix (included).
- Consent for any real face or voice. If the character is based on a real person, you need their written permission first, covering how long it lasts and what happens if they leave.
An exit test before kickoff: can you hand over a ZIP of the approved master images plus the spec today? If the identity only exists inside one account, price in the cost of recreating it elsewhere.
Plan 12 to 20 posts as scene families on one calendar
Put the whole month on one calendar before you generate a single image. Give each post to one of 4 to 6 scene families, for example:
| Scene family | Example post | Posts in a month |
|---|---|---|
| Greeting | Monday hello with the week's theme | 4 |
| Product | Character holding or pointing at an item | 4 |
| Tip | Character explaining one quick tip | 3 |
| Reaction | Character reacts to news or a customer question | 2 |
| Offer | Character with a sale banner | 2 |
| Behind the scenes | Character in the workshop or office | 1 |
Then generate one family at a time, in one session, with the same reference and the same style setting. Different days and different people produce different faces. Also plan the layout: where the text goes, where the logo sits, and the safe zones for square, 4:5 and 9:16 formats. Preview each post as it will look on a phone.
Give the character a voice, not only a face
A character that looks the same but sounds different each week still feels loose. Before you generate anything, write a short voice card and put it in the same folder as the spec:
- A name and a one-sentence role ("Pip, the shop's helpful fox").
- Three personality words, and one thing the character never says (no medical claims, no jokes about customers).
- Reading level and language, and whether it uses emoji.
- Two sample captions the client has already approved, so a new writer can match them.
The first-person caution still applies: a made-up character may speak for the brand, but it should not claim a personal experience such as "I used this for a year".
Build the reference set first, and test it before the month starts
Do not start the month with the reference unproven. Spend the first day on the reference sheet and a short readiness test, the one described in the mascot guide. If the character fails the test, you want to find out before you have promised 16 posts, not after.
Make stills first. A face that is stable in stills can change during speech or from the side in video, so only extend the character into video after the stills pass. Marketing Studio, Higgsfield's template workspace for ads and product videos, says reusing the same avatar across ad variations keeps the same face, but voiceover and pacing vary by generation and should be reviewed. See the Marketing Studio guide.
Where Higgsfield fits for the batch work, and where it does not
Higgsfield is useful for the batch stage: many scenes with one character, in one place, with its own image model Soul 2.0 and the Soul ID feature for a realistic person. Soul ID suits a realistic invented character or a consenting real person. It is a poor default for a flat cartoon. For scenes with two or more consistent characters, Higgsfield's help center points to a different feature called Elements, because one Soul ID holds only one person. The Soul ID guide has the steps.
What it costs, as Higgsfield prints it (check the current pricing page): Starter is $19 a month with 270 credits, Plus is $59 a month ($47 on annual billing) with 1,200 credits, and Ultra is $129 ($99 annual) with 3,000. Soul 2.0 is listed at 0.12 credits per image. Soul ID training cost and Marketing Studio costs are not published, so read the number on the button before you run. Subscription credits reset each cycle and do not roll over, so a quiet month wastes them. Credit packs are valid for 90 days. Time the plan to the production weeks, or consider a monthly plan rather than a year up front for a small retainer. See how to spend credits and the pricing explainer.
It is not the right pick when: the character must talk in video every week (HeyGen or Synthesia, an online tool that turns text into videos with AI presenters, are built for that), the client wants a simple cartoon (use a drawn set), or the client will not accept any dependency on a vendor account.

Other options
- Midjourney, an AI image tool with a painted and illustrated look. Its Edit model takes up to 4 reference images. Standard is $30 a month and Pro is $60 (check the vendor page; annual billing is 20 percent off). Companies over $1,000,000 gross yearly revenue must use Pro or Mega for commercial use, which may affect larger clients.
- Canva, a design tool, is good for the template layer that holds the character, text and logo. I do not quote its price here; check the vendor page.
- HeyGen, a tool for talking-avatar videos, suits posts where the character speaks. Its listed plans: Free $0 (3 watermarked videos a month), Creator $29 a month ($24 billed yearly), Pro $49 ($41 yearly), Business $149 plus $20 per seat. Check the vendor page for current prices.
- A freelance video editor or UGC creator for any post that must feel real. Ask for a quote.
Batch, curate, review: the weekly rhythm and the two-gate approval
A simple weekly rhythm works well:
- Monday: generate one scene family in a batch. Plan for rejects.
- Tuesday: curate. Pick the winners and drop the rest.
- Wednesday: apply the template (text, logo, safe zones).
- Thursday: two-gate approval.
- Friday: schedule, and archive the approved files, the prompts and the sign-off.
Split approval into two gates. Gate 1 is the agency: does the character match the reference sheet? Gate 2 is the client: do they approve the message? Keeping the gates separate stops a client from asking for "a new look" halfway through when the real issue was a caption. Use one named approver on each side, a preview that looks like the phone screen, and a version history.
Cost and capacity math, with illustrative numbers
All numbers here are made up to show the arithmetic. Replace them with your own.
- 16 posts a month. If only 4 of 10 generations are on-model, you need 16 divided by 0.4, which is 40 generations.
- Review time: about 30 minutes per 8 posts for the identity check, plus the template work and the client round.
- Credits: multiply generations by the per-image cost shown on the button. Do not use a headline price.
- Bill the client for the review and planning hours, not for "AI time".
Compare against the no-AI route: an illustrator for 6 poses once plus template work. If the AI month does not beat that by a clear margin after review time, use the drawn set.
A 7-day pilot with pass and fail rules
A plan you can run before you commit to a full month:
- Make 6 posts across 2 scene families.
- Show them to the client in a preview link or a mock phone screen.
- Track the first-time approval rate and the minutes of review per post.
- Pass: at least 4 of 6 are approved with no changes to the character itself, and review time is under your budget. Fail: fewer than 4, or the client asks to redesign the character. A fail means the spec is too vague or the tool class is wrong. Fix that before you take the retainer.
Risks to put in the plan
- Drift between weeks. One person owns the reference and the style setting.
- Tool or plan change. Keep an offline copy of masters, prompts and settings.
- Client changes their mind. The change policy in the contract handles this.
- Audience reaction. Do not present the character as a real person or customer; check each platform's current labelling rules.
- Billing. Higgsfield's Trustpilot page (Trustpilot is a public review site) showed 4.0 from 5,281 reviews on 2026-11-03 (re-check before relying on it), and the reviews include complaints about credits expiring and annual-plan refunds. Opinions, not facts, but they are a reason to start monthly.
Who should skip an AI character for this client
- The client wants authenticity, such as real customers and real staff: hire real creators.
- The client will not sign any wording about tools, ownership or exit.
- Fewer than about 10 posts a month: a drawn set and a template is simpler.
- Nobody can spare the review time. Unreviewed AI posts are how a brand gets embarrassed.
How I'd approach this
I would sell the pilot first, as a paid week, and put the contract paragraph in before any images exist. I would draw or pick the master, run the readiness test, and only then quote the month. For the batch stage I would use the platform that already fits the client's character type, and I would keep every approved file in a folder the client can take away. If you want to try the batch workflow, start with Higgsfield here.
If you run several clients, the repeatable part is the portal: a place where the spec, the references, the batches and the two approvals live. Blur Studio builds that kind of approval portal and shared asset library around these tools. You can see what that looks like.
Questions people ask
How many posts can one character cover?
As many as you have scene families for. A month of 12 to 20 posts across 4 to 6 families is a sensible size. More than that, and you should check for audience fatigue and for drift.
Who owns the character at the end of the contract?
Whatever you agree in writing. State who owns the final images and reference set, which tool made them and what the client receives at exit. This is not legal advice, so have a lawyer review it and check each tool's current terms. Do not promise a trained character the client cannot take with them.
Can I move the character to another tool?
You can move the approved images and the spec. A trained identity may not move: Higgsfield says a Soul ID cannot be exported as a standalone file. Keep the master images and prompts so you can rebuild the character elsewhere. See the Soul ID guide.
What if the client dislikes the character halfway through?
This is why you have a change policy and a pilot. Separate fixes (included) from a new look (paid), and approve the character in the pilot before the full month starts.
Do I tell followers it is an AI character?
A clearly fictional mascot is different from a realistic face, but do not present any synthetic character as a real person or a real customer. Platform rules on AI labels differ and change, so check the current rules for each platform. See the rules page.
How do I stop drift between weeks?
Use one reference set, one style setting and one named owner. Generate one scene family per session, and check every image against the reference sheet, not memory.
Do unused credits roll over?
On Higgsfield, subscription credits reset each cycle and do not roll over. Credit packs are valid for 90 days, and you need an active subscription to buy them. Check the current help center and pricing page, and see the credits guide.
