Fermat

Fermat is a fashion-oriented generative AI workspace for turning apparel ideas into visual concepts. It is strongest for designers and brands refining garments and brand imagery; its focused tools are appealing, but ongoing use depends on paid credits.

Overview

Fermat groups more than 40 generative tools by workflow, covering fashion and luxury design from moodboards to realistic renders, materials, and virtual model fitting. The specialization makes it a better fit for apparel development than a general image-making workflow: sketch rendering and garment edits are core uses. The trade-off is a credit allowance that can limit how freely teams explore.

Key features

• Sketch rendering: Turn apparel sketches into photorealistic images and preview designs in fabric before making a sample. That is useful for evaluating concepts before physical sampling, though the visuals do not replace a sample.
• Design iteration: Change sleeves, hems, necklines, fit, and length without redrawing. This targets repeated garment revisions, but each image generation uses one credit.
• Custom Styles: Upload visual references and train image models to produce images in a chosen style. This gives brands a way to steer outputs toward a visual direction rather than start from an unanchored prompt.
• Tool Editor: Build internal company frontends around public or private AI models with a no-code editor. It is relevant to organizations that want an internal workflow, rather than only individual image creation.
• Privacy and control: Fermat says customer generations, prompts, references, and uploads are not used to train its own or third-party foundation models. Customers retain intellectual property ownership, and each brand gets an isolated workspace with private generated content. Its security page lists SOC Type I and SOC2 Type II; enterprise controls include SSO, on-premises options, admin roles, model opt-outs, and GDPR compliance.
• API and automation: Enterprise includes batch processing and API, custom workflows, and custom tools. These features suit organizations integrating generation into established processes, but they sit behind custom pricing.

Pricing

Fermat has a free Starter tier and paid Pro and Studio plans, with Enterprise on custom pricing. Each image generation costs one credit and each video generation costs four; Starter's one credit is therefore a brief sample, not a working monthly allowance.

• Fermat Starter: free, with 1 credit. This is enough to glimpse the workflow, but not to support regular exploration.
• Fermat Pro (monthly): $30 a month, billed per month, for 150 credits per month, latest AI models and updates, an assets library, image model training, full content ownership, a commercial license, high-resolution export, and private generations. It is the stated fit for individuals and freelancers; the monthly credits suit measured use, while video consumes them four times faster than images.
• Fermat Pro (annual): $330 a year, billed $330 per year; the page also shows $360. It includes the Pro features and 150 credits per month, with the option to buy more credits as needed. This lowers the stated annual bill compared with paying $30.00 monthly for twelve months, but commits the buyer to annual billing.
• Fermat Studio (monthly): $250 a month, billed per month, for 500 credits per month, team access, unlimited users, 8/5 support, and Pro features. It is aimed at small teams and agencies; the higher price buys team access and a larger shared workflow rather than a per-seat cap.
• Fermat Studio (annual): $2,700 a year, billed $2700 per year; the page also shows $3000. It includes Studio features and 500 credits per month, with additional credits available to buy. Annual billing costs less than twelve monthly payments at 250.00 USD, in exchange for a yearly commitment.
• Fermat Enterprise: Custom pricing, billed Contact us, on monthly or annual terms. It offers custom monthly credits, white label, a customer success manager, custom SLA, SSO, batch processing and API, custom workflows, and custom subdomain deployment. It fits organizations needing deployment and administrative controls, not buyers looking for a published fixed price.

Credits renew on the 1st for the monthly Pro plan. The annual Pro and Studio plans also state monthly credit allowances and the option to buy more as you go. The distinction to weigh is not just price: Pro is for individual use, while Studio adds team access and 8/5 support.

Platforms

Fermat is available on web and through an API. The API is a platform option, while Enterprise specifically includes API and batch-processing features.

Who it's for

Fermat is best for apparel designers and fashion or luxury brands that need to turn sketches into renderings, iterate on garment details, or generate imagery in a chosen style. Pro fits individuals and freelancers; Studio is the more natural choice for small teams and agencies that need team access and support. Enterprise is the option for organizations that need SSO, custom workflows, or deployment controls. It is a weaker fit for casual users who want to experiment without managing a small credit budget.

Pros and cons

• Pro: More than 40 tools organized by workflow, with sketch rendering and garment-specific edits aimed directly at apparel development.
• Pro: Private brand workspaces, customer ownership of generations, and a stated no-training policy address important concerns for proprietary design work.
• Pro: Studio allows unlimited users and includes 8/5 support, rather than charging by seat in the stated plan.
• Con: Starter's single credit permits little evaluation, and video generations cost four credits each.
• Con: Enterprise capabilities such as API automation, custom workflows, and SSO require a custom-priced plan.
• Con: The annual Pro and Studio prices each appear alongside a higher figure on the page, so buyers should confirm the billed amount before committing.

Alternatives

For apparel sketch workflows, compare Fermat with the broader AI Sketch-to-Image Generators list. Choose Vizcom if a free plan with 800 credits and basic AI creation tools is more important than Fermat's fashion-specific workflow. FLORA Fashion Studio is another fashion-focused option; its free tier includes one seat, three active projects, and up to 17 free generations, while its Starter plan is $18 a month.

Gendo offers a free web plan with unlimited generations, but watermarks outputs and limits collaboration to one collaborator. Consider LookX AI if a free allowance of 100 images or a $20.00 USD monthly subscription better suits your budget. Neolocus AI has a free 30-credit plan and a one-time $18.00 USD Starter plan, making it an option for buyers who prefer a one-off payment.

Raspberry AI Prints & Patterns is worth comparing for a free 50-credit allowance or an Individual plan at $49 a month. Spacely AI offers 40 trial credits on a free-forever plan, while Fashion Diffusion is an alternative with Android and iOS apps as well as web access.

Verdict

Choose Fermat if apparel sketch-to-render work, garment iteration, and private brand imagery are central to your workflow. Pro is the practical starting point for an individual, while Studio makes more sense when a team needs shared access and support. Look elsewhere if a one-credit free tier is too narrow to judge the product or if you need enterprise automation at a published price.
