# SumizAI vs Gepette

Looking for a Gepette alternative? SumizAI and Gepette side by side: price, licence, platforms and what each one actually does.

## What Gepette is

AlternativeTo files Gepette under AI Coding Assistant. It is recorded as Freemium, Proprietary. It ships on Mac, Windows, Linux. The topics its entry raises are code.

That is our reading of the record. For AlternativeTo's own wording, see [its page for Gepette](https://alternativeto.net/software/gepette/about/) — the facts above were read on 2026-08-16.

## Gepette in depth

### A tool built around one specific complaint

Gepette exists because of a problem that anyone who has pasted code into a chat window will recognise. You want the model to change something in a codebase, so you gather the relevant files, paste them in one by one, add the instruction, remember the formatting conventions you want followed, and then discover you have blown past the context limit or forgotten the file that actually mattered. The application, written by an independent developer named Zhu Liang, turns that improvised ritual into a repeatable interface: you pick source files from a project tree, write the task, attach reusable formatting instructions, and the app assembles a single prompt with a running token count so you can see the budget before you spend it.

The distinguishing decision is that it is a desktop program rather than a service. It runs locally on macOS, Windows and Linux, and prompt assembly happens on the machine — the vendor states plainly that the app works without an internet connection and that nothing is stored on company servers. Network traffic only occurs if you choose to send a prompt to a model provider through the built-in API integration, and in that case the request goes directly from your machine to the provider using your own key.

### What it does beyond assembling text

The feature set has grown well past prompt construction. Workspaces let you register multiple repositories and treat them as one context, which matters for the common case of a frontend and a backend living in separate checkouts where a single change touches both. Custom instructions are saved task templates — refactoring conventions, documentation style, testing expectations — that can be attached to any prompt instead of retyped. Saved prompts cover the same ground for whole requests you run often.

A newer capability, present in the 0.0.107 generation of the app, moves it from prompt authoring into code editing: the app can apply the model's suggested changes to your files with a visual diff, and the changes are reversible. That places it in overlapping territory with editor-integrated assistants, though with a different posture — you still assemble context deliberately rather than letting an agent decide what to read. There is also a side-by-side comparison mode for running the same prompt against different models via API and judging the outputs against each other, which is genuinely useful when deciding whether a cheaper model is good enough for a given class of task.

### Model providers and the bring-your-own-key requirement

The app is provider-agnostic and ships integrations for OpenAI, Anthropic's Claude, Google Gemini, DeepSeek, OpenRouter, Azure OpenAI and Ollama for local models, plus generic support for OpenAI-compatible endpoints, with Fireworks, Hyperbolic and DeepInfra named explicitly. Code context works with all mainstream languages — Python, JavaScript, TypeScript, Java, C++ and SQL are the ones the vendor lists — and the documentation calls out common frameworks including React, Vue, Next.js, Flask and Django.

One point deserves emphasis because it trips people up regularly, and the vendor addresses it directly in the documentation: a ChatGPT Plus or Claude Pro subscription does not include API access. Using the API features means creating a developer account with each provider and funding it separately, and some models require a prepaid balance before they will respond. The licence you buy for Gepette covers the software only; every token you send is billed by the model provider. For light users this can work out cheaper than a chat subscription, and for heavy users considerably more expensive. It is worth modelling before switching over.

### Pricing, and a stale figure in the directory

The AlternativeTo entry lists a one-time purchase of twelve dollars. That figure is out of date and anyone planning around it will be surprised. Current pricing on the vendor's site is a free tier limited to ten prompts per day with full local functionality including source code management, formatting instructions, prompt copying and Anthropic and OpenAI API access; an Individual lifetime licence at forty-eight US dollars, activating on up to three devices; and a Team lifetime licence at sixty-eight US dollars, activating on up to ten devices and adding company invoicing with a name and tax identification number plus priority support. Volume discounts and white-label arrangements are offered on request for larger buyers.

Two policies around the licence are stated bluntly and both are worth knowing before purchase. Licences include free updates with no expiry, which is unusual and favourable in a market drifting toward annual renewals. Against that, there are no refunds at all — the vendor attributes this to the cost of processing them through Stripe. Given that, the ten-prompts-per-day free tier is not a teaser but the actual evaluation mechanism, and it should be used properly. Device management is self-service: since version 0.0.59 you can deactivate a machine yourself and move the licence, without opening a support ticket.

### Platforms, packaging and known gaps

macOS gets a native application, Windows an installer, and Linux is served by a Debian package and an AppImage. One compatibility note in the documentation is that Windows 8 is no longer supported. There is no mobile version and no browser version, which is consistent with the local-execution design but rules out working from a machine you cannot install software on.

The AlternativeTo record is sparse in a way that is itself informative. The entry was created on 7 March 2024, updated the following day, and has since gathered six likes, no comments and no reviews, with eighteen alternatives listed against it. The directory reduces the feature list to two flags — ad-free and works offline — and tags it under ChatGPT, productivity tool and developer tools. The offline flag is accurate and arguably the single most important thing on that page, but the absence of any user commentary means there is no independent account of how the diff-and-apply feature behaves on messy real-world repositories.

### Judging whether it fits your workflow

- It suits developers who want deliberate, auditable control over exactly which files a model sees, rather than an agent that crawls the repository on its own.
- It suits people who already hold API keys and want to compare providers without maintaining separate scripts.
- It suits environments where code must not be uploaded to a vendor's servers as part of the tooling, since the app itself stores nothing remotely.
- It suits anyone allergic to subscriptions, given the perpetual licence and free updates.

It fits poorly if you want an agent that plans and executes multi-file changes on its own initiative, if you need mobile or web access, if a no-refund policy is a procurement blocker, or if you were expecting the software licence to cover model usage. It is also a single-developer product, which cuts both ways: release cadence has been brisk and the version numbering suggests frequent iteration, but there is no organisation behind it if the author steps away.

For anyone comparing this with SumizAI, the overlap is limited. Gepette is a context-assembly and code-editing utility aimed at programmers who bring their own model access; it is not an end-user assistant and does not answer questions itself. The decision between them is less a feature comparison than a question of whether your work is writing software.

## What SumizAI is

A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.

A vault is a directory holding `base.md`, a generated table of contents up to six levels deep, and a `notes/` folder with one `.md` file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.

The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

## Where they differ

- Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what Gepette does with the model bill before comparing prices.
- Gepette is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
- AlternativeTo's description of Gepette does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard `.md` files to a folder you picked, and an unpaid account can still export all of them.
- AlternativeTo lists no mobile version of Gepette. SumizAI runs on macOS, Windows, iOS and Android.
