The player's side of the table
Gnasher's Satchel™
Your character, in your pocket. A free, 5E-compatible sheet that rolls with one tap, tracks the fight for you, and links live to your DM's screen. No account. No subscription. Works in a basement with no signal.
Free forever · opens in your browser · installs on your phone · your characters never leave your device
Gnasher carries your dice, your sheet, and your notes, and he rolls right alongside you.
Phone, tablet, or laptop
Bring whatever screen you bring to game night. It loads like a page and behaves like an app.
Add it to your home screen
iPhone: tap Share, then Add to Home Screen. Android: open the menu and pick Install app. It gets its own icon.
Signal optional
After that first visit it opens offline, sheet and dice and all. Rather own the file outright? The download gives you the whole app as one file.
What's in the bag
Everything a player reaches for, and nothing they have to set up.
A sheet in three minutes
Pick a class and a level and your proficiency, saves, hit dice and spell slots fill themselves in. Or build one from scratch in the Forge, with every number computed for you.
Tap to roll
Every check, save, skill, and attack rolls with one tap, advantage and disadvantage included, with an honest result card and a session log you can clear.
The bookkeeping face
One-tap damage and healing, temp HP, conditions, and rests that do the right thing. At 0 the hit-point plaque turns into death saves by itself, with a Healed button waiting.
Your resources, as coins
Rage, Second Wind, Action Surge, Channel Divinity, Bardic Inspiration, Sorcery Points and the rest sit on the Fight tab, grown from your level, spent with a tap, handed back by the right rest.
Spells that keep their own count
Cast one and pick the slot. Concentrate on one and the sheet asks for the save when you take a hit. Prepared spells are counted against your level, so you always know where you stand.
The whole SRD, a search away
Every rule, action, feat, feature and item in the free SRD 5.2.1 is one search from your sheet, and the dice written into the text are ready to roll where they sit.
The live table
Your DM reads a short code off Gnasher's Grimoire; you type it in. Your rolls appear at the table, the initiative order lights up when it's your turn, and handouts land in your Journal.
Phones sleep. Fine.
When your screen dozes off, your seat is held. The Satchel rejoins by itself when you wake it, and anything you missed, even a private whisper from the DM, is already waiting.
Yours, forever
Everything lives on your device. Export a .satchel file any time to back up or move phones. No account to lose, nothing to cancel.
When your character gets complicated
The parts that usually end up on a sticky note next to the sheet.
Wild Shape, and the sheet becomes the beast
A Druid wears a form and the whole sheet turns into the animal until you drop it. Add a form once under Companions & Forms and it is waiting the next time you need it.
Familiars, steeds and summons
Anything you bring to the fight carries its own hit points and its own attacks on the Fight tab, so your owl is not being tracked on the back of a napkin.
Multiclass without the spreadsheet
Add a class with one button and the Satchel keeps the math straight underneath: hit dice, proficiency, and which ability each half of you casts with.
Every other speed
Fly, swim, climb, burrow. Other speeds and your darkvision sit right beside your walking speed, where you can see them on the turn you actually need them.
Level when you are ready
When your XP earns a level the sheet asks whether you want it now, shows you what the level brings, and then moves every number that should move.
No character? Pull up a chair
Join your DM's table with nothing but your name and watch the fight from the top of the screen. Make a character later and your handouts move into its binder.
Bring your own books
The Satchel ships with the free SRD 5.2.1 and nothing else, on purpose. The rest of your table is yours to bring.
Drop the files in
Drop them anywhere into your Satchel, several at once. A .satchel backup, a D&D Beyond character or a Foundry VTT actor becomes a character. A .md or .txt note becomes a page in the open character's binder. A .csv, .tsv or .xlsx sheet becomes a page you can roll on. A PDF, EPUB, Word or 5eTools file is a book.
Your Books holds the rest
Species, backgrounds, feats, spells, items, armor, whole classes and subclasses. Three ways in: type an entry yourself, load a book file, or read a book you already own. Every one shows up in the Forge the moment you keep it.
Then build, in about three minutes
Species, background, class, feats, spells and gear, with your own material sitting in the same lists as the SRD. Tick what your table uses, leave the rest, and every number computes itself. Most of the three minutes is you reading your own book.
- It stays in this browser. The Satchel never sends your material anywhere, and nothing you put in can be shared from inside the app. That is deliberate. Your books are yours.
- A name clash never overwrites you. Where your entry shares a name with the SRD, the SRD keeps the plain name and yours carries its book's name after it. Take a book back out and the characters built from it keep their names and say plainly what is no longer installed.
Free rulebook packs
Open rulebooks, already packaged for the Forge. Download one, load it in Your Books, and its options sit in the same lists as the SRD, picked the same way, computed the same way. No account, no sign-in, nothing phones home.
This is somebody else’s rulebook, shared under the open licence its publisher chose, and the pack carries its credit line inside it. We are not affiliated with EN Publishing. Take it back out whenever you like. A pack is never welded in.
Running the game instead? Gnasher’s Grimoire has more of them, whole bestiaries and spell lists, built for the table behind the screen.
Install to rolling, in ten steps
The same walkthrough lives inside the app, under How to use in your Satchel.
- Install it. Open the Satchel. iPhone: Safari's Share button, then Add to Home Screen. Android: Chrome's menu, then Add to Home screen, then Install.
- Or tap "Try a sample hero" when your Satchel is still empty: a ready-made Fighter, every number real, so you can tap things before you build anything.
- Make a character with + New Character: name, class, level, and the Standard array button for instant ability scores. Three minutes, playable.
- Or bring your D&D Beyond character. Set it to Public on dndbeyond.com (Manage, then Character Settings, then Privacy), then paste your character's link into the Satchel's Import. It opens your data page in a new tab; select all, copy, tap Paste, done. You carry your own data; the Satchel never fetches it for you.
- Or bring your Foundry character: right-click the actor, Export Data, and feed the .json to Import.
- Roll by tapping. Any ability, save, skill, or attack rolls itself, bonus included. Set Adv or Dis on the dice tray first when it matters.
- Run the fight from the Fight tab. Damage, Heal, and Temp HP live inside the hit-point plaque; at 0 HP it becomes death saves, and a Healed button waits there for your cleric. Conditions, slots, hit dice, class resources, and rests are all one tap.
- Level up in the Study. Tap Level up: the Satchel shows what the level brings, asks for your subclass or your Ability Score Improvement or feat, files the features you gain, and moves every number that should move.
- Join the table. Tap the wax seal, type the short code your DM reads out, tap Join. The seal glows when you're linked and remembers the code for next week.
- Play. A YOUR TURN banner takes the top of the screen when the fight reaches you. DM handouts and whispers land in your Journal, where you can rename, tag, and annotate them.
- Keep notes. Journal tab: dated Session Notes, free Campaign Notes pages, and your handout shelf.
- Back it up. Journal tab, Export .satchel. One small file is your whole character; Import brings it back on any device.
For DMs: light the table in five steps
You host from Gnasher's Grimoire; your players just point their Satchels at it.
- Open Gnasher's Grimoire and tap Theater in the menu bar.
- Tap Open the table by code and read the code aloud. Each player types it into their Satchel's wax seal. (No venue internet? Same room mode or your phone's hotspot.)
- Run combat exactly as you always do; the tracker drives every paired Satchel by itself, turn banners included.
- Push handouts (text or images) from the Theater panel; pick one name in the To row to whisper it privately.
- Phones that doze show as resting seats. Keep playing; they catch up the moment they wake.
The other half of the table
Your DM runs it from the Grimoire
Gnasher's Grimoire is the free binder that holds every adventure, summons any table or monster in a keystroke, and drives the initiative your Satchel watches for. The two are built for each other.
- Free, offline DM app: holds your whole library.
- Hosts the live table your Satchel links into.
- The War Table your initiative bar is reading from.

Who pays for this
No company, no investors, no ads, and nothing in the Satchel calls home. It is one DM on Long Island, building the tools he wanted at his own table. The Satchel is free and it stays free.
Two things keep it going. People buy Keepers, the adventures, tables and packs that drop into the Grimoire. And people become Patrons, or donate.
Patron · $25, once. It unlocks nothing, because nothing is locked. There is no tier that opens a feature you already have on your phone. What it buys is art. Icons and covers get commissioned from artists, and this is what pays for them.
- Your name on the Patrons’ Page
- The patrons’ room in the Discord, where I answer first
- A vote that counts on what gets forged next
Take it. It's free.
The Satchel is one file. Open it, join your DM's table with a code, and your character, your dice and your handouts stay on your own device. No account. No install. Nothing lost when the wifi drops.
Open the Satchel Send your DM the GrimoireEver run a game yourself? The Bi-Weekly One-Shot is free, and every issue is an adventure the Grimoire is built to hold. Signing up free also gets you the DM's Field Kit.
The companion line: Gnasher's Grimoire™ (the DM app) · Gnasher's Satchel™ (the player app) · Gnasher's Quill™ (the session recorder).
the Quill records → the Grimoire holds → the Satchel carries. Free tools live in The Hoard.
