for people who want to write, play, and be remembered — without the setup
A gentle place for the characters you love — one that remembers your story, keeps what you make yours, and never asks you to be an engineer.
Hosted web runs the full app in your browser at app.sparklochat.com — chats, characters, themes, community, and long-term memory in one place.
Prefer your pocket? The Android app carries its own local engine, so private data and provider keys stay on your device.
Maybe you've gotten used to hopping between a few apps: chatting with AI in one, jotting down a stray thought in another, picking a character's story back up somewhere else, and stringing it all together with a handful of API keys.
More tools, and somehow nothing gets easier. Every new app means learning its settings and its vocabulary all over again — while your memories, your data, and your stories sit scattered in different places, sometimes held together by nothing more than a few hand-written lines of code.
Sparklo wants to bring all of it back into one place.
Here, you can jot down an idea as it comes, talk with your AI, try something fun — or return to a character you love and pick up the story you never finished. Clear settings, flexible plugins, and dependable long-term memory quietly hold on to everything that happens along the way.
You just have to come back. It remembers where the two of you left off.
Whether you're writing, playing, or simply talking.
Sparklo keeps track of who your characters are, the world you built, and what already happened — so four hundred messages later, they can still bring up the detail that mattered. When Sparklo saves a memory, you can see it happen in plain language, not inside a black box. Sometimes the character even saves something important on their own.
Not every conversation needs a plot. Work through an idea, sort out something small from everyday life, or spend an unhurried moment with a character you love. Sparklo makes room for all of it, without making you start over each time.
Dress the whole app in a theme, add a touch of atmosphere, and choose its sounds. Tie a theme to a character, so the mood shifts the moment they arrive. Browse themes made by other people, or share your own.
Bring your own provider key — on Android, it stays on your device — or top up a hosted balance and choose the exact model you want. Either way, model usage is pay-as-you-go. Hosted usage shows what each message cost, and the membership never hides model charges inside a bundle.
Private app data stays where it should: on your device on Android, and in your own private account space on the web. Cloud sync is there when you want it. Sparklo doesn't sell your data or turn your private story into a public feed.
We're opening the doors slowly — not to be exclusive, but to give the community room to stay kind and worth protecting. One simple membership covers the app, your private cloud sync, and the creator community.
Model usage is separate and pay-as-you-go: bring your own provider key, or top up a hosted balance when you want it. There is no trial — but the price, what's included, and how model usage is billed are shown plainly before you decide.
Sparklo keeps software membership and model consumption separate. The membership unlocks the app, cloud sync, community services, and platform embedding support; chat model usage stays flexible so you can pick the billing route that fits you.
Connect your own Anthropic, OpenAI/GPT, Gemini, OpenRouter, or compatible API profile. Android/local mode calls from your device; Hosted Web uses an encrypted account vault.
Top up Sparks to use Sparklo-hosted model channels from partners such as official Anthropic, AWS Bedrock, Google Gemini, OpenAI/GPT-compatible providers, and more. Rates are shown per model inside the app.
Hosted model calls are tracked with provider, model, request time, token usage, and Sparks balance movement, so spending stays visible instead of mysterious.
Connect your own Codex or Claude Code authorization for Sparklo-supported coding-agent workflows. Those external authorizations stay separate from the membership.
Want a reminder before the next access wave? Leave your email here. Invite codes only create beta accounts; app use and APK downloads still require membership or an existing grant.
In-app balance for Sparklo-hosted model usage, official store items, and creator tips. Everything shared in the community — characters, worlds, themes — is free to enjoy.
Community themes are shared freely by the people who made them. The official store carries Sparklo-made items and feature packs, purchased with Sparks.
Great creators deserve recognition. Send Sparks as a tip to show your appreciation — a simple, heartfelt way to say "your character made my day."
Sparklo was made by one person who wanted a kinder place to write: somewhere characters remember, what you make stays yours, and you don't need to be an engineer to feel at home.
When the tools I had reached their limits, I stopped patching them and began building Sparklo.
Sparklo — spark (a small flash of inspiration) + lo (small, gentle, close).
No. You can add a little hosted balance and use a Sparklo-provided model, or bring your own provider key if you prefer. On Android, your provider key stays on your device.
About US$3.6 per month covers the Sparklo app, private cloud sync, and the creator community. Chat-model usage is separate and billed only when you use it, through either your own provider account or Sparklo-hosted balance.
No. Invite codes only allow beta registration. App access and APK downloads require a Sparklo membership or an existing access grant. See Pricing for details.
Sparklo-hosted model calls use Sparks balance and are tracked with provider, model, request time, token usage, and balance movement. Model rates can differ by provider and model, so Sparklo shows rates in the app and keeps usage records visible instead of bundling model credits into the membership price.
In Android and local modes, private app data stays on your device. Hosted Web keeps private app data in a separate account space for each user. Creator-protected content follows Sparklo's protection flow, and we don't sell user data. Full details are available in the Privacy Policy.
Sparklo doesn't add a filter of its own on top of your private chats. What a model will or won't write is up to the model and its provider — that's true whether you bring your own key or use hosted balance. Different models draw their lines in different places, and none of them are entirely without limits, so it's worth choosing one whose range fits the story you want to tell. Content shared publicly in the community is a different space, and follows the Community Guidelines.
Not from external file formats. Sparklo's native character and world systems are built around creator protection, and keeping that boundary intact is intentional.
Yes. Sparklo can support connecting your own Codex or Claude Code authorization for supported coding-agent workflows. Those authorizations belong to your external account and stay separate from the membership.
Every character deserves to be remembered.
Every creator deserves to be seen.
