## Napkin AI

Napkin AI is a visual communication platform that turns plain text into diagrams, infographics, flowcharts, mind maps, data charts, and full presentation decks — no prompt engineering required.

**Preços e planos:** Freemium. The free plan includes weekly AI credits, unlimited editing, unlimited file imports (PPT, DOC, PDF, HTML, MD), and unlimited PNG and PDF exports. Paid Plus and Pro plans unlock more AI credits plus PPT and SVG export, custom branding, and additional design options. Full details are on the Napkin pricing page.

- **Text-to-visual generation:** Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
- **Presentation decks:** Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
- **Fully editable output:** Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
- **Flexible export formats:** Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.

**Pontos fortes:** No prompt engineering — it works directly from your existing text; Generates a wide range of visual types, from flowcharts to data charts; Everything stays editable and brand-matchable after generation; Free plan includes unlimited imports and PNG/PDF exports

**Limitações:** Free plan is credit-limited and some exports (PPT/SVG) and branding options sit behind paid tiers; Visual generation is not yet available on mobile; desktop is still the best experience; Generated visuals still usually need some manual styling to fully match a brand

## Rivet.dev

Rivet is open-source infrastructure for running and scaling AI agents as "Actors" — durable, stateful compute units that live inside your own Node.js or Bun backend. Each Actor keeps persistent state, a filesystem, and a SQLite database, so agents survive restarts, share state, and run code written at runtime without a redeploy. Rivet ships as a single stateless Rust binary and can be self-hosted, run in your VPC, or used through a managed cloud.

**Preços e planos:** Rivet Cloud uses a plan-plus-nodes model. The control plane is Free ($0) for prototyping, Hobby at $10/month, Team at $120/month, and Enterprise at $900/month, each raising control-plane redundancy, Actor Node caps, and support. Actor Nodes are billed per month on top, from $4.20 (R-5) to $94.50 (R-160). Self-hosting is free and open source under Apache 2.0, and startups from Y Combinator or a16z Speedrun get 50% off the Team plan for 12 months.

- **Durable actors with persistent state:** Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
- **Lightweight secure sandboxing:** Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
- **Fault tolerance and workflows:** A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
- **Realtime and multiplayer:** Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
- **One-binary deployment and observability:** Ship with a single stateless Rust binary, embeds storage in S3-compatible buckets, and emits OpenTelemetry traces, metrics, and logs to your existing collector.

**Pontos fortes:** Four-digit millisecond cold starts and a very small per-Actor memory footprint let a single server host far more agents; Open source (Apache 2.0) with a single Rust binary, so it can be self-hosted, run in a VPC, or air-gapped; Durable state via per-Actor SQLite plus object-storage-backed tiers keeps agents restart-safe and cheap; Strong developer ergonomics: typed SDKs, a React SDK, WebSocket networking, and OpenTelemetry baked in

**Limitações:** Requires Node.js or Bun and a working Rust-based control plane deployment for self-hosting, so it favors backend engineers over no-code users; Advanced durability and sandboxing concepts (Actors, WarpDrive storage) carry a learning curve; Managed cloud cost scales with Actor Nodes, which can climb for many mid-sized/sized nodes; Enterprise features like multi-tenancy and hardened compliance guidance sit behind sales conversations
