You can start from a description and let the built-in Zite AI assemble a ready-to-publish form in your brand, or drag and drop fields manually. Every submission is stored in a structured database you can filter, analyze, and connect to other tools. Beyond basic data collection, Fillout adds intelligent routing, login-based forms that let respondents edit their own answers, digital signatures, and native integrations with 50+ apps. Branding is fully controllable, including custom domains, white-labeling, and embeds as popups, sliders, or full-screen pages. A large number of organizations use Fillout for secure data intake, and the service advertises SOC II Type 2 compliance plus AES-256 encryption. A free tier covers casual use, while paid plans unlock advanced logic, higher limits, and team features. **Pricing & Plans:** Freemium. A free plan covers basic forms and submissions, with paid tiers for advanced logic, higher limits, file uploads, payments, and team collaboration. - **AI form builder (Zite):** Describe the form you need in plain language and Zite generates a branded form with logic, file uploads, and payments. - **Logic and workflows:** Add conditional logic, intelligent routing, and multi-step workflows to automate what happens after each response. - **Editable and secure submissions:** Respondents can log in to update their answers, and forms can be restricted to internal users only. - **Branding and embeds:** Use custom themes, fonts, logos, custom CSS, your own domain, and embed forms as popups, sliders, or full-screen pages. - **50+ integrations and analytics:** Send responses to spreadsheets, CRMs, and other tools, then review and collaborate on results with flexible views. **Strengths:** AI-assisted building makes first drafts fast; Deep logic, workflows, and 50+ integrations; Strong branding controls including white-label and custom domains; SOC II Type 2 compliance and AES-256 encryption **Limitations:** Advanced features require paid plans; Feature depth can be overwhelming for simple one-off forms; Popular templates see heavy competition for the same look [Profile (Markdown)](https://openaitools.app/tool/fillout-com.md) ## Pi Coding Agent Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn. Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing. Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site. **Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself. - **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git. - **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control. - **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session. - **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent. - **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL. **Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options **Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI [Profile (Markdown)](https://openaitools.app/tool/pi-coding-agent.md) ## Frequently Asked Questions ### How do Fillout and Pi Coding Agent compare in monthly traffic?
