No more copy-pasting out of chatbots. Build Perch runs on your machine, not in the cloud, with the tools to research, write documents, generate media, and automate your work. Control your costs, quality, and privacy through 400+ models, from the latest and greatest to ones hosted locally.
Built for Windows 11 · see how it stays private →
Example: ask Build Perch to fill your own PowerPoint template with product info. It opens the template, pulls images and product info from your workspace, and fills the placeholders with layouts intact. Other examples: save a workflow that summarizes each week's invoices into a PDF on a Friday schedule; turn study notes into flashcards, one card per concept, and get quizzed on them; write a client rundown as a Word document from your own files; or break an hour-long recording into 12 captioned vertical clips, processed on your PC. All of it can use any of 400+ models through OpenRouter or local models with Ollama.
See it in action
Screenshots from the current build, taken in a staged demo workspace.
A research chat in progress. Every tool call shows as an activity row, and the reply carries the exact model that wrote it plus a live context meter.
Pick any model, eyes open
Connecting a chat opens the live model catalog, with each model’s context window, per-token rate, and tool support in one table.
Scope each chat
A chat carries only the skills you give it. Toggle bundles or single tools and the token cost of what’s enabled updates live.
Build your own modes
Modes and skills are editable. Write the description the AI sees, pick the exact tools a skill grants, and save your own presets.
Set the limits
Defaults for every new chat: how many tool rounds and web searches a turn may use, when to summarize, and how much the AI can read per call.
Search that stays home
Files are chunked and embedded into a local database that never syncs to a cloud, so the AI can find things by meaning. Pause or rebuild any time.
See every run
The Activity window lists what ran and where: each chat, agent, and workflow run with its workspace, status, and how long it took.
Why Build Perch
Build Perch gives you tools to organize your data locally while improving privacy and safety, with full control over the capabilities and access each AI model receives.
Turn a chat into a native Word, Excel, PowerPoint, PDF, or webpage, or fill your own branded template. Build Perch works with 75+ file types, and every edit is snapshotted, so one right-click reverts whatever a reply changed.
Generate images, speech, music, and video, then trim, reframe, caption, and transcribe it on your own machine with a bundled FFmpeg.
Ask what you decided in March and get it from your own files, chats, and task cards. Full semantic search covers 49 file types, including Word, Excel, PowerPoint, and PDF, and the index runs on your CPU with nothing shipped to a cloud.
A built-in Kanban system with customizable stages, priorities, and deadlines that the AI can read, update, and pull into chats as context.
Save an agent, chain a few into a workflow, and fire it on a schedule, an email, a Discord post, or a changed file. It asks before anything leaves.
By default, every tool call shows up in plain English to allow or deny. Reply in your own words to redirect it, or turn on auto-approve when you want the AI to run on its own. You set the level of control.
Integrations
Your choice of models, a focused set of the apps you already use, and the open web. Each stays off until you turn it on, with credentials kept in your OS keychain.
Three ways to run models: pay-as-you-go for 400+ through OpenRouter, a subscription on Ollama Cloud, or free and local with Ollama.
Off until you connect them. Secrets stay in your OS keychain.
