Make any app
AI-Native in minutes.
Connect your app and deploy. Faustine turns it into a conversational assistant that actually gets things done — no agents to build, no AI stack to maintain. The best models, working inside your product.
Connect, detect, done.
No rewrites and no custom agent code. Connect your repo, Faustine detects what your product can do, and your app gets an assistant that takes action for real.
Add AI to your app. Today.
Normally, adding AI to a product means hiring specialists, building an agent from scratch, and maintaining it forever — months of work. Faustine does all of it for you. Today. Here's what's no longer your job:
It doesn't just answer. It does the work.
A support bot replies. Faustine acts. It works inside your app, looks things up on the web, and runs multi-step tasks end to end — pulling the order, issuing the refund, sending the email — while the customer just watches it get done.
- Works inside your app. Reads and writes real data through the actions you expose — not a copy, your live product.
- Reaches the web. Looks up what it needs — carrier status, pricing, public records — to finish the job.
- Finishes tasks. Chains the steps a person would and completes them end to end, not just suggests them.
Teach it how your product actually works.
Point Faustine at your docs, playbooks and best practices and it grounds every answer in them. The assistant learns the right way to use your app, follows your team's strategies, and responds like the operator who knows your product best — not a generic bot guessing from a prompt.
Update a doc and the assistant knows it. No retraining, no redeploy.
Nothing ships that you didn't approve.
Every capability is opt-in and scoped. Switch actions on one at a time, keep the risky ones read-only, and see exactly what the assistant can touch. And because each capability is real code in your repo, your team can read it, change it, and improve it like any other part of your stack.
- Per-action permissions. Ship read-only first, then enable each write when you're ready for it.
- It's your code. Every tool lives in your repo and ships through your PRs and reviews.
- Full visibility. See every action the assistant took, on what, and why.
It can only do what your users already can.
Faustine isn't a backdoor. The assistant drives your existing UI as the signed-in user — same session, same auth, same permissions. It's just a different way to use your app, not a new way in.
- Acts as the signed-in user.Every action runs through your UI with the user's own session, auth and scopes — never more.
- No custom backend. Nothing to deploy and nothing running on your servers — it uses the same frontend your users do.
- No separate permissions.There's no second access model to audit; your existing rules already govern everything it can touch.
Frontier intelligence, none of the ops.
Your assistant runs on the best models available — Claude, GPT and more. You don't manage keys, evals or migrations: Faustine picks the right model for the job and rolls forward as better ones ship.
Switch providers whenever you want. Your product code never changes.
Token compression, on by default.
Every request is squeezed before it reaches the model. Faustine reuses the context that repeats, prunes stale tool output, and summarizes long conversations on the fly — so you get the same answers for a fraction of the tokens, with nothing to configure.
- Prompt caching. Repeated context is reused across requests instead of re-sent and re-billed.
- Context pruning. Stale tool results and dead branches are dropped before they cost you.
- Live compaction. Long histories are summarized automatically as the conversation grows.
Works with the stack you already ship.
Faustine drops into any modern frontend — React, Vue, Angular and the rest. One snippet, your framework, your build pipeline. No migration, no rewrite, no special runtime.
+ any HTML app — if it runs in a browser, it's one script tag.
It keeps up. You don't babysit it.
Faustine isn't a one-time generator. It's the layer that watches how your assistant is used and keeps it in step with your product as you ship.
Zero to production. Today.
Connect your app, switch on the actions you want, and ship the assistant. You'll have it live before your coffee's cold.
