Question 1

Do we have to migrate our existing AI tools?

Accepted Answer

No. Tendril is code- and model-agnostic. Whatever you are running today (Claude, Codex, Antigravity, GPT, an open-weight model, your own .NET stack), we work with it. The orchestration layer sits on top.

Question 2

What about EU regulatory requirements?

Accepted Answer

We design for it. Tendril supports routing specific tasks to specific models, so sensitive work can stay on EU-hosted or on-prem models while other work uses frontier capability. We can detail this in the scoping conversation.

Question 3

How long until we see results?

Accepted Answer

It depends on the engagement: Boardroom Briefing. A single 90-minute session. Move Faster Package. Your dev team typically starts shipping code in 2–3 weeks. Full Implementation. Scope-dependent, but throughput change is typically visible within the first quarter.

Question 4

What does "level 8" actually mean in practice?

Accepted Answer

A custom orchestrator with three primitives: a shared task queue (so agents never duplicate work), a coordinator process (assigns tasks based on availability and priority), and checkpointing (recovers from failures cleanly). Layered on top: custom agents tuned to your domain, persistent memory so the system learns over time, and measurement so output is observable and improvable. The short version is in section 2 of this document.

Question 5

What if we want to start with the open-source version and engage later?

Accepted Answer

That is genuinely a great path. Many of our customers started exactly there. Build something, get stuck, then talk to us about taking it the rest of the way.

Question 6

What is Tendril?

Accepted Answer

Tendril is a desktop app that makes ad-hoc AI coding structured, verifiable, and self-improving. It manages AI coding agents with a plan-based lifecycle, two human checkpoints, automated verifications, and continuous agent learning. It brings structure to AI development like CI/CD did for deployment.

Question 7

Who is Tendril for?

Accepted Answer

Tendril is for any size development team adopting structured AI coding. It's ideal for teams that need local-first, multi-stack support or want to avoid vendor lock-in. Tendril scales from solo developers to large engineering teams.

Question 8

What problem does Tendril solve?

Accepted Answer

Raw AI coding agents are inconsistent and lack oversight. Tendril turns them into orchestrated workers with persistent memory, automated quality checks, and targeted human control.

Question 9

What does the workflow look like?

Accepted Answer

There are exactly two human touchpoints: 1. Review the plan before execution 2. Review the diff before PR creation Everything else is automated.

Question 10

What are promptwares?

Accepted Answer

A promptware unit is a self-contained, self-improving agent. Each one contains: Program.md - Task-specific instructions that evolve over time Memory/ - Persistent learnings across sessions Tools/ - Scoped permissions defining what the agent can access Logs/ - Full execution history for auditability Tendril ships with built-in promptwares for each stage of the lifecycle: CreatePlan, ExpandPlan, ExecutePlan, UpdatePlan, SplitPlan, CreatePr, and CreateIssue.

Question 11

Which AI coding agents does Tendril support?

Accepted Answer

Tendril is agent-agnostic. Currently supported agents include: Claude Code (Anthropic) OpenAI Codex CLI Antigravity CLI On customer request, we can make Tendril work with any CLI-based agent.

Question 12

Which AI models can I use?

Accepted Answer

Tendril is model-agnostic. Supported models include: Claude Opus, Sonnet, Haiku (Anthropic) - through Claude Code. GPT-4o, o3 (OpenAI) - through Codex. Gemini 2.5 Pro (Google) - through Antigravity. On customer request, we can make Tendril work with basically any model.

Question 13

Can I use my own API keys?

Accepted Answer

Yes. Tendril runs locally and uses your own API keys for whichever LLM provider you choose. There is no Tendril-hosted proxy or middleman. You maintain full control over your API relationship, usage limits, and spend.

Question 14

Can I switch agents or models without disrupting my workflow?

Accepted Answer

Yes. Plans, memory, and verification gates are independent of the agent and model. Switch providers at any time - your accumulated knowledge and workflow configuration carry over completely.

Question 15

What tech stacks does Tendril support?

Accepted Answer

Tendril is stack-agnostic. One Tendril instance manages all your projects regardless of language or framework.

Question 16

Is Tendril cloud-based?

Accepted Answer

No. Tendril is a local-first desktop application. Your code never leaves your machine. The only external calls are to the LLM API (which you choose) and GitHub. This makes it ideal for regulated industries and teams with strict data sovereignty requirements.

Question 17

What platforms does Tendril run on?

Accepted Answer

Tendril supports: Windows 10 or later macOS 12 (Monterey) or later Linux - Ubuntu 22.04+, Fedora 36+, Debian 12+, or any distribution with WebKitGTK 4.1+

Question 18

How is Tendril different from Copilot, Cursor, or Windsurf?

Accepted Answer

Those tools operate inside your IDE and assist with inline code generation (autocomplete, chat, inline edits). Tendril operates above that layer - it manages the full lifecycle from ticket to merged PR, with plans, verification gates, and agent memory. You can use Tendril alongside any IDE tool. They complement each other.

Question 19

How is Tendril different from Devin or Factory AI?

Accepted Answer

Devin and Factory are cloud-hosted autonomous agents. Your code goes to their servers, you're locked to their models, and there's limited human oversight in the loop. Tendril is local-first (code stays on your machine), agent-agnostic (you pick the agent and model), and built around two defined human checkpoints rather than full autonomy.

Question 20

What does Tendril cost?

Accepted Answer

Tendril is open-source and free. We offer enterprise companies help with setup and support plans.

Question 21

Are there usage limits or credits?

Accepted Answer

No. Tendril itself has no usage limits, token caps, or credit system. You use it as much as you want. The only variable cost is your LLM API usage, which you pay directly to your chosen provider at their rates.

Question 22

Does my code leave my machine?

Accepted Answer

No. Tendril is a desktop application with a local-first architecture. The only external communication is with the LLM API of your choice and GitHub. Your code, plans, and agent memory all stay on your machine.

Question 23

Do you train on my code?

Accepted Answer

No. Tendril never sees your code. It runs locally on your machine and orchestrates agents that also run locally. The only external calls are to the LLM API you choose and GitHub. Whether the LLM provider trains on your code depends on their terms and your API agreement - Tendril itself stores nothing externally.

Question 24

How long does it take to set up?

Accepted Answer

Ivy offers a 3-day on-site implementation engagement: Day - FocusDay 1 - Foundation - install, configure, connect ticket systems, set up verification pipelines Day 2 - Training - onboard team, define quality criteria, implement self-improvement loop Day 3 - Handoff - stabilize, culture workshop, document, transfer ownership For self-service, you can get started immediately.
