Sketchly AI · the lead featureDescribe an app.
Describe an app.
Get a wireframe, a plan, and a repo.
Sketchly turns a one-sentence idea into clickable mobile or website wireframes, then into a Codex-ready project brief, then into a downloadable starter repo — all without leaving DevHelper. You stay in the creator seat; AI handles the tedium.
1Step 01 · Sketch
Draw screens by hand — or describe them in plain English.
Konva-powered canvas with mobile and website templates. Hit Cmd/Ctrl+K, type "a meditation app with onboarding, streaks, and a daily session list", and Sketchly AI lays the screens out — navbars, content blocks, buttons, cards — following mobile or web conventions.
- Mobile + website wireframe templates
- Multi-screen, infinite-canvas project tabs
- Streaming AI replies you can stop or refine mid-flight
- Auto-clear large chat context — no hard 400 on token caps
2Step 02 · Theme
Pick a brand brief — every screen updates instantly.
Each Sketchly project carries a complete theme: a full palette, body + heading fonts, sharp/soft/pill radii, a mood string. Type "warm cream + indigo, editorial, soft serif", click Generate theme with AI — the entire wireframe rebrands in one go. You override anything by hand.
- AI-generated themes from a one-line brand brief
- Chat-aware theming: "make the primary indigo" updates only theme
- Per-element overrides when you want them
- Theme block ships into the project plan as design tokens
3Step 03 · Plan
One brief, two ways to ship it.
Click Plan. The model walks you through adaptive scoping questions — frontend, backend, auth, codegen — branching on your previous answers. Out comes a plan.md with mermaid navigation, ER and dependency diagrams, plus every screen as a PNG. From here you pick your path: download the ZIP and hand it to any coding agent, or stay in DevHelper and hit Code it for a one-click wireframe → repo flow inside the app.
- End-to-end inside DevHelper, or download the bundle and pass it to any agent
- Smart-branching scoping (Flutter / SwiftUI skip styling branches)
- Mermaid diagrams: navigation, ER, build order — embedded in plan.md
- ZIP: plan.md + per-screen PNGs — Codex, Claude Code, Cursor, anywhere
Plan flow · from prompt to finished brief01 / 03
← swipe or tap a dot →
1 · Adaptive question
Each next question branches on your previous picks. Web and mobile templates surface different option sets, each with a "Recommended" default.
4Step 04 · Interactive Plan
Build it one screen at a time.
Big plan turns can sit on a single reasoning call for minutes. Interactive Plan splits the work: a small draft first, then one screen at a time on Continue — so you can inspect, redirect or stop after every step. Soft canvas lock: pan and zoom stay free.
- Screens land as they’re built — no single long wait
- Pause between every step — Continue or Stop
- See the screen-by-screen plan before any builds start
- Optional per project — flip back to one-shot Plan anytime
5Step 05 · Code it
One click. Codex writes the whole app.
Press the green Code it button and walk away. OpenAI Codex takes your full plan — every screen, every flow, every data model — and writes the whole app to match what you designed: same layout, same theme, same components, same navigation. What you sketched is what gets built. DevHelper drops the complete project on your computer (components, routes, API stubs, styles, config files — the lot), ready to open in your editor (or hand to another AI agent) and run. No code experience required.
- The running app matches your wireframes — layout, theme, components, flows
- A complete project in your chosen stack — files validated before saving
- Open in your editor, or hand off to Claude Code / Cursor
- No tokens used on errors, Stops, or dropped streams

The model
Free by nature. Kept alive by you.
DevHelper has no investors, no ads, and no subscriptions. The whole project runs on community support — and the math is built so when you chip in, you win too.
01
Everything is free to start with.
Download the app, claim your welcome voucher, use Sketchly AI from day one — without spending anything. A temp email is fine. No tier locked behind a paywall, no "first 7 days" trial, no credit card.
02
Donations come back to you — and the community.
When you donate, the split looks like this:
- →Most of it comes back to you as AI tokens.
- →The rest seeds a community buffer that tops up free-tier users when they hit their cap, plus the running costs.
03
The more we grow, the closer DevHelper gets to self-sustaining.
Every new user who joins and chips in makes the community buffer a little bigger and the AI pool deeper. With enough community, DevHelper funds itself indefinitely — no investors, no Pro tier later, no rug-pull. Just the same free app, year after year.
Nothing is sold. Nothing is locked. The only paid layer is voluntary, and most of it comes back to the people who chip in. That's the whole deal.
Transparency · live
Every dollar, on the record.
DevHelper has no investor runway and no Pro tier to lean on, so we publish the real cost of keeping the project alive. The numbers below update live from our backend — every server bill, every promo we run, every shared AI subscription. If the community covers this, the project keeps shipping.

We need $220/month just to keep DevHelper online. Every coffee literally pays the bill — and most of it comes back to you as AI tokens anyway.
Free AI · funded by the community
Donate a coffee. Get most of it back as AI tokens.
DevHelper has no subscription, no tiers, no ads. AI features are funded by a community pool — and your tokens work across every AI-powered app inside DevHelper (Sketchly today, more on the way). Every Buy Me a Coffee donation is split: most of it comes back to you as DevHelper AI vouchers, emailed within ~5 minutes — and the rest keeps the lights on (servers, code-signing certs, the developer's caffeine).
Want to sponsor a community pool instead? Companies and individuals can fund a shared bundle that covers free-tier users who hit their cap — sponsors get their logo and link shown inside the app while community members are using their credits.

There's so much more we want to build.
Your support is what ships it.
AI in more apps, smarter wireframes, deeper project plans, sharper extensions, and a few ideas we're still keeping under wraps — there's a long list of features waiting on community support. Your donation is what turns those ideas into real things you can use inside DevHelper. And the bonus: most of every donation comes back to you as DevHelper AI tokens you can spend in the app today.
Buy me a coffeeFAQ
Common questions.
Yes. Every feature, every export, every limit raised. No Lite/Pro tiers, no subscriptions, no ads. AI features are also free — tokens are funded by community donations through Buy Me a Coffee, and the same tokens work across every AI-powered app inside DevHelper.
Sign-up exists to protect the shared OpenAI credits from abuse — temp / throwaway emails are explicitly welcome. Signing in lets you claim a welcome voucher, your monthly quota, and (optionally) cloud sync. Local tools work without an account.
Every BMC donation is split: most of it comes back to you as a DevHelper AI voucher, emailed within ~5 minutes (a polling pipeline against BMC's API mints SKAI-XXXX codes). The remainder covers operating costs — servers, Windows code-signing, hosting. You paste the code in-app and credits stack on top of your quota — usable across every AI app inside DevHelper. Tier values are configurable in admin and may shift as model prices change.
Locally on your machine. Sketchly tabs, chat history, themes, plans and notes are stored in DevHelper's local data folder. Sign-in unlocks optional cloud sync (25 MB compressed). New:
.dhsp Sketchly project files double-click straight into the app.Almost everything is local-first — your wireframes, themes, notes, diagram tabs and JSON tabs sit on your machine and never leave unless you ask. The AI features are the exception: when you hit Generate, Plan or Code it, your prompt and the relevant wireframe data are sent through DevHelper to OpenAI so the model can respond. Cloud backup is optional and you turn it on yourself. Nothing is sold, nothing is used to train third-party models.
Yes — there's a Feedback panel built into the app's left sidebar. Every idea, bug report and feature request goes straight to the developer's inbox, and most fixes show up in the next release or two. Since DevHelper's AI features are community-funded, your support also helps decide which features get built first.
No — your quota only ticks on a successful AI completion. Network errors, model truncations, Stop clicks, and dropped streams don't spend any tokens at all.
