Why Tendril

Built to actually finish the job.

Most AI tools give you one assistant in a chat window and hope for the best. Tendril runs a team of AI workers in parallel, carries the lessons from your past projects into the new one, keeps your code on your own computer, and reviews its own work before it tells you it's done.

Remembers every project you build

Tendril carries the decisions, conventions, and patterns from your past projects into the one you're building now. Solve something once and you won't have to re-explain it. Build five apps, and the sixth starts already knowing how you like things done. The more you build, the smarter it gets, and you never have to write a single note to make that happen.

A team of AI workers, not one chatbot

Instead of one AI answering you in a chat, Tendril puts several AI workers on a visual board and sets them building different parts of your app at the same time. Each one works in its own safe workspace, so they never trip over each other or overwrite one another's work. You see the whole thing happen live, and the number of workers on a project isn't artificially capped. You can have up to 5 projects active at once.

A board that fills itself in

Describe what you want and Tendril breaks it into tasks on a board, then moves each one from To Do to In Progress to Done as the AI workers finish. The most important pieces get built first, and the rest run side by side. You watch the progress instead of babysitting every small decision.

See it live, then point at what's wrong

Your app runs right inside Tendril, so you can use it as you build. Spot something off? Circle it, type one sentence about what should change, and send. That note turns straight into a fix on the board and gets done. It's the fastest way to go from ‘this looks wrong’ to ‘this is fixed’ in any AI building tool.

Use the AI you already like

Tendril works with Claude, GPT, or Gemini. You pick one for each project. Already pay for Claude Pro or Max? Just sign in and use it directly, no extra setup. Prefer your own account key from any of them? Drop it in. Either way, you're free to build with the AI you trust.

AI runs in a locked sandbox, and you approve every change

Every AI worker runs in a safe workspace where it can't touch anything it shouldn't. Genuinely dangerous moves, like wiping files, writing outside your project, or peeking at secret files, are blocked automatically. And nothing gets saved to your project until you say yes. You're always the one who approves what ships.

A locked sandbox you control

AI workers run in their own safe workspace, dangerous actions are blocked, and nothing is saved until you approve it.

Tendril quality audit scores on subtasks

Checks its own work

Pro

Every part of your project is reviewed and scored before it's called done, and the issues it can fix get fixed.

Review the plan first

Before any building starts, you see the plan laid out as tasks. Approve it, change it, or drop pieces you don't want. You stay in charge.

A team building in parallel

Several AI workers build different parts of your app at the same time, each in its own safe workspace, all on one board.

You get nearly all of this on every plan. Paid plans mainly raise how much you can build, and Pro founding pricing is locked in for the first 200 members.
